Municipal Utility Districts

What is a Municipal Utility District?

A Municipal Utility District (MUD) is a special-purpose districts which are created to provide public utilities, which may include one or more of the following services, to the homeowners and businesses within the MUD;

• ambulance

• electricity

• fire

• garbage & waste collection

• natural gas

• sewage/wastewater treatment

• water

• wholesale telecommunications

MUDs are created by an election of the voters within the proposed MUD, and by board of directors who are voted on by the local people. As governmental entities, they operate as a nonprofit.

Public Utility Districts (PUDs) are similar to MUDs but created by a local governmental body such as a city or a county, but has no authority to levy taxes.

____________________________________________________

____________________________________________________

A Municipal Utility District, or "MUD" is a district that has been created and authorized by a developer that may provide for one or more utilities or services, to those residing within the MUD.  Examples of utilities or services that may be provided to resident and businesses within the MUD may include one or more of the following; energy and renewable energy in the form of natural gas, electricity, solar power/energy, water, wastewater treatment plants, storm water drainage, telecommunications, as well as other services deemed necessary within that specific MUDs boundaries that could include police, fire and ambulance services.

How is a MUD created?

This depends upon the state that the proposed MUD is located in.  Typically, a majority of the property owners in the proposed MUD's boundaries district petition that state's respective governing body for creating the MUD.  The regulating body that provides the oversight for MUDs will evaluate the petition, conduct one or more public hearings, and then determine whether to grant or deny the petition. If the MUD is approved, a temporary MUD Board of Directors (or Commissioners, again, dependingon the state) is established that may be comprised of three to five temporary members to the MUD's Board of Directors.  This is only until an election is called to permanently elect the MUDs Board of Directors, and to confirm/ratify the MUD's creation. After which time, the MUD may authorize bonds and levy taxes for the repayment of the bond(s). 

How does a MUD work?

The publicly elected Board of Directors of a MUD manages and controls all of the affairs within that MUD as it relates to the charter for that MUD.  The Board of Directors will establish policies, rules and other guidelines on behalf of the residents and utility customers of their MUD.  A MUD will adopt and enforce all necessary charges, fees and taxes in order to provide for the MUDs facilities and services it was created for providing.

How do MUDs provide for parks and recreation facilities?

In addition to their common functions of water and wastewater service, MUDs may be empowered to engage in conservation, electrical power generation, irrigation, firefighting, solid waste collection and disposal, stormwater drainage, as well as recreational activities such as parks, bicycle/jogging paths, swimming pools, tennis courts and basketball courts/gymnasiums. 

What are the developer's responsibilities to the MUD they helped create?

This will depend on the state that the MUD is located in.  In general, a developer petitions the appropriate governing body for that state, to create the MUD. 

Developers are usually prevented from serving or placing employees, business associates, or family members on the MUD's Board of Directors that the help create. 

Developers must pay for or put up a letter of credit equal to 30% of the cost of subdivision utilities. This requirement ensures against "fly-by-night operators" who are not committed to the success of the MUD. The "30% rule" also offers protection to MUD residents in the event that a subdivision is not built according to schedule. Unless they are voting residents within a MUD, developers have no authority or control over the MUD's Board of Directors. If they are voting members of a district, they have the same power to vote and attend Board meetings as any other resident. 

What is a Public Utility District?

A Public Utility District, or "PUD" is a special-purpose district or a jurisdiction established by a governmental body that provides for public utilities (such as electricity, natural gas, water, sanitary sewers/waste water treatment plants, municipal solid waste collection, and more recently, wholesale telecommunications) for the residents of that Public Utility District.

PUDs are created by a local government body, such as a city, county, or metropolitan service area (two or more communities joining together for public utility purposes). Normally the districts are non-profit.

PUDs are often governed by a commission, which may be appointed or elected.

Again, a "Municipal Utility District" or "MUD" is very similar to a PUD, but MUDs are created by private developers instead of government.

In the past, some of the Public Utility Districts in the Pacific Northwest were created with the purpose of taking over the electric power service territory served by investor-owned utilities - and then serving those customers within that newly-created PUD's territory. The creation of many of these Public Utility Districts were possible due to favorable laws in those states at the time and with the direct assistance of individuals in various federal agencies that were strong proponents of public ownership of electric utilities such as Dr. Paul J. Raver of the Bonneville Power Administration.


More About Municipal Utility Districts and Public Utility Districts 

Introduction

As electric utilities continue to raise electric rates on their ratepayers/customers - citizens, cities, and municipalities are asking companies such as ours to assist them in building their own power generation plants and distributing the electricity to themselves. For most cities and municipalities, the creation of a Municipal Utility District (MUD) or a Public Utility District (PUD) will quickly enable a city or municipality to send the "dis-connect" notice to their respective electric utility. 

A Municipal Utility District (MUD), and a Public Utility District (PUD) are very similar in that they are both like a school district, and are governmental entities, which are created under State law. Each state has its' own laws regarding MUD or PUD creation, and the requirements vary from state to state. MUD's and PUD's may also supply water and wastewater treatment systems.

As a public entity, a MUD or PUD can exercise certain governmental powers, including the levy and collection of property taxes, charging for authorized services, the issuance of bonds for water, sewer, wastewater and electrical power facilities, and the adoption and enforcement of rules and regulations as appropriate to accomplish the purposes for which the district was created.

A MUD or PUD may also be a customer-owned utility, committed to providing electricity on a cost of service basis as a customer service -- not to make a profit for stockholders or shareholders of Independently-Owned Utilities, which have a responsibility to make a profit, and then share those profits to their shareholders, via dividends. This only occurs after they pay their enormous overhead costs and along with overly-generous, and even outrageous salaries to their top management - whose responsibilities are to generate as much of a profit for their shareholders, at the expense of their customers, or ratepayers, that are paying these increasingly greater electric rates. 

MUD's and PUD's are typically governed by a Board of Commissioners. The board sets MUD/PUD policy, employs the General Manager and guides the district's operations. Members serve a term from 2-4 year terms, and normally elected by voters in that district. The General Manager is directly responsible to the Board of Commissioners. In carrying out the policies of the Board of Commissioners and in conducting the business operations of the district, the General Manager is supported by a trained staff, which includes approximately 45 employees. 

Purpose of the Electric Power Generation, Transmission and Distribution District 

The chief purpose of electric power MUD's or PUD's is to generate, transmit and distribute electrical power for the citizens and ratepayers of that specific district. The district owns and operates an electric distribution system serving its' ratepayers. 

Overview on California Municipal Utility Districts (MUD) 

California cities are increasingly turning towards “Municipal Utility Districts” (MUD) as a way to lower utility costs and increase energy efficiencies. This is because a Municipal Utility District is an independent agency – or a public power agency -- that provides for one or more essential public services, such as electricity, to residents and businesses. 

Environmental responsibility 

Municipal Utility Districts and public power agencies can rely more on renewable sources of energy than investor-owned utilities. If a community is environmentally aware, MUD’s will explore alternative energies such as cogeneration and trigeneration. 

Accountability

As public-owned agencies, Municipal Utility Districts must comply with state open-meetings and public-records laws. Public power systems are governed democratically at the local level. Most -- especially the smaller ones -- are governed by a city council, while others are governed by an independently elected board. Control stays in the hands of the community. 

Savings for customers

Municipal Utility Districts charge less than private enterprise. On a national average, private power company residential customers pay about 18% more for electricity than public power customers. Public power utilities, on average, return to state and local governments in-lieu-of tax payments and other contributions that are equivalent to state and local taxes paid by private power companies. 

To establish a Municipal Utility District, the developer or community must strictly follow their respective state's regulations. 

The Steps and Process How We Help Communities and Developers and Establish a MUD or PUD

Again, each state is unique, and have their own respective laws and regulations relating to the establishment of MUDs and PUDs.  

In general, we follow the following steps: 

1. Commission a feasibility study to:

* Evaluate a community's needs for services after which we will design a solution which is better, more efficient, environmentally-friendly and sustainable.

* Determine whether the public entity should be a Municipal Utility District (MUD) or a Municipal Utility (the latter can be created exclusively by an action of the City Council or County Board of Supervisors). 

2. Assuming community opts for a MUD, draft a qualifying petition seeking the creation
of a MUD in accordance with that state's MUD regulations. 

3. Coordinate governmental agencies, including the Board of Supervisors, the Office of the Clerk of the Board, the Department of Elections and the Office of the City Attorney, if there is one. 

4. Obtain enough signatures to equal 10 percent of the total votes (or whatever the state's requirements are) that were cast in the last general election to enable placement of a ballot measure for the creation of a utility district.

5. Sponsor election and elect the temporary Board of Directors.

6. Create “wards” of equal apportionment in the community (or City).  For some states they may be referred to as districts. 

7. Assist the Board of Directors and a newly appointed General Manager for the MUD to handle operations and necessary approvals. 

8. Determine the benefits of incur indebtedness, issuing bonds and investing funds. 

9. Implement all aspects of conversion and installation of new "clean" power generation system.

What are Solar Power Parks?

A Solar Power Park is a large photovoltaic power plant installation that is located near a "load center" such as a city or community, that sends all of its "dedicated" power to that city or nearby load center. 

What is a Power Purchase Agreement? 

A Power Purchase Agreement is a legal agreement wherein our clients agree to buy either the power (electricity) or the power and energy (hot water, steam and/or chilled water for air-conditioning) - or both - directly from us, for a term of 10 to 20 years, where we have installed, own and operate our solar energy systems. 

In nearly every case, once we have installed our solar energy systems at our client's facility, we can immediately reduce our (commercial) client's electricity expenses by 10% over what they were paying for their power electricity from their electric utility.

The right Power Purchase Agreement, solar cogeneration or solar trigeneration energy solution, may save your company hundreds of thousands, and possibly millions of dollars over the term of the agreement.  

Simultaneously, having the wrong or poorly drafted PPA can cost your company thousands or millions of dollars.  You wouldn't consult a brain surgeon to treat your child's broken bone!  Selecting the wrong attorneys, law firm or team to promulgate or re-negotiate your Power Purchase Agreement can leave you "powerless" and penniless - and still requiring the skills and expertise of competent and qualified professionals to resolve the situation.     

Because a Power Purchase Agreement is at the "heart" and underlying foundation of our projects, we can help your business with the selection and oversight of PPA's. 

We can help your city or community create a Municipal Utility District or Public Utility District that may then qualify for our very competitively priced energy and electricity rates. Now is the time for cities, municipal and governmental clients to consider having our company install one of our renewable power and energy systems that will generate "clean" power and energy, lower costs, and avoid the coming electricity shortages and grid congestion problems!

A host customer agrees to have solar panels installed on its property, typically its roof, and signs a long-term contract with the solar services provider to purchase the generated power. The host property can be either owned or leased (note that for leased properties, solar financing works best for customers that have a long-term lease). The purchase price of the generated electricity is typically at or slightly below the retail electric rate the host customer would pay its utility service provider. 

Solar Power Purchase Agreement rates can be fixed, but they often contain an annual price escalator in the range of one to five percent to account for system efficiency decreases as the system ages and inflation-related costs increases for system operation, monitoring, maintenance, and anticipated increases in the price of grid-delivered electricity. A Solar Power Purchase Agreement is a performance-based arrangement in which the host customer pays only for what the system produces. The term length of most Solar Power Purchase Agreements can range from six years (i.e., the time by which available tax benefits are fully realized) to as long as 25 years.

The solar services provider functions as the project coordinator, arranging the financing, design, permitting, and construction of the system. The solar services provider purchases the solar panels for the project from a PV manufacturer, who provides warranties for system equipment.

The installer will design the system, specify the appropriate system components, and may perform the follow-up maintenance over the life of the PV system. To install the system, the solar services provider might use an in-house team of installers or have a contractual relationship with an independent installer. Once the Solar Power Purchase Agreement contract is signed, a typical installation can usually be completed in three to six months.

An investor provides equity financing and receives the federal and state tax benefits for which the system is eligible. Under certain circumstances, the investor and the solar services provider may together form a special purpose entity for the project to function as the legal entity that receives and distributes to the investor payments from the sale of the systems kWh output and tax benefits.

The utility serving the host customer provides an interconnection from the PV system to the grid, and continues its electric service with the host customer to cover the periods during which the system is producing less than the site’s electric demand. Certain states have net metering requirements in place that provide a method of crediting customers who produce electricity on-site for generation in excess of their own electricity consumption. In most states, the utility will credit excess electricity produced from the PV system, although the compensation varies significantly depending on state polices.

More about Power Purchase Agreements

A Power Purchase Agreement is "behind" almost every power plant.  A PPA is a contract involving the generation and sales of electricity - which is normally developed between the owner of a power plant generating the electricity, and the buyer of the electricity. PPA's can be quite lengthy agreements that may exceed 100 pages in length and take several months to even 1-2 years to finalize.  

The basic information contained in a Power Purchase Agreement include the following items:

          * Definitions
          * Purchase and Sale of Contracted Capacity and Energy (such as steam, hot
             water and/or chilled water in the case of cogeneration and trigeneration
             plants
          * Operation of the Power Plant
          * Financing of the Power Plant
          * Guarantees of Performance
          * Penalties
          * Payments
          * Force Majeure
          * Default and Early Termination
          * Miscellaneous
          * T&C's

What is "Net Zero Energy^sm?"

Net Zero Energy^sm - when applied to a home or commercial building, simply means that the home or buildings generates as much power and energy as they consume, when measured on a monthly or annual basis, and with an onsite, renewable energy system, such as our Solar Trigeneration^sm Energy System. 

What is a Net Zero Energy Building^sm?

A Net Zero Energy Building^sm produces as much energy as it uses over the course of a year. Net Zero Energy Buildings^sm are very energy efficient. The remaining low energy needs are typically met with on-site renewable energy. 

First of all, understand that there is no such thing as a "zero energy building!" EVERY building uses energy, or you may as well be in a cave!  

The important considerations are, 

1.  How efficient is the building?  

2.  How much energy does the building use, and how efficiently is it used?  

3.  How much "carbon free energy" or "pollution free power" is generated by the buildings' own onsite renewable energy system?

4.  What are the utility company's prices for the excess power generated and sent to the grid? 
(see: Net Energy Metering)

5.  How difficult is it to interconnect the renewable energy system of the building with the utility company's powerlines/electric grid?   

At the heart of a Net Zero Energy Building^sm is the idea that any building can meet its energy requirements from low-cost, locally available, nonpolluting, renewable sources, like our Solar Trigeneration^sm Energy Systems. Our Solar Trigeneration^sm Energy Systems are the idea whose time has come, to make Net Zero Energy Buildings^sm commonplace.

Solar Trigeneration^sm Energy Systems Provide All of the Cooling, Heating & Power, for Any Size Building, with only the Energy of the Sun. Solar Trigeneration^sm Energy Systems Provide Simultaneous  Cooling, Heating & Power whether it is 12 Noon, or 12 Midnight,  and can do so, WITHOUT Connection to the electric grid!

The Diagram Below Shows How Our Solar Trigeneration^sm Energy System Works, 
for Heating and Cooling a Building (next to the Solar Thermal Collectors, are the PV Panels, that generate the Electricity).

Our Solar Trigeneration^sm Energy System
provides "Cooling, Heating & Power" for your business,
or home with the free energy of the sun!

What is Net Energy Metering?

Net energy metering is used to measure a customer's total electric consumption against that customer's total on-site electric generation.  When a customer's onsite generation of power exceeds the amount that they use, the customer's solar energy system (or other renewable energy system) exports the extra electricity to the grid.  When the power requirements of the customer exceeds their onsite generation of power, the customer imports the electricity they need from electric grid. The customer pays the electric company for any extra power they use over the amount they generate - OR -  the customer receives a credit or refund from the electric company if they exported more power to the grid, than what they consumed.  

Renewable Energy Is Necessary for Net Zero Energy Buildings

Much focus is placed on energy efficiency as the most cost-effective way to reduce energy use in commercial buildings. However, consumption can be reduced only so much. There is a point at which the cost of adding efficiency measures is higher than that of using renewable energy such as thin film photovoltaics and other solar energy systems. 

Aggressive energy efficiency strategies can reduce a building's energy consumption by 50% to 70%. Renewable energy technologies must be used to reach the goal of a net-zero energy building (NZEB).

Supply-Side Technologies

Various supply-side renewable energy technologies are available for Net Zero Energy Buildings. Supply-side technologies, often called energy producers, collect natural energy and transform it into a useful form. Examples of these technologies include PV, solar hot water, wind, hydroelectric, and biofuels.

Ranking of Energy Options

All renewable sources are favorable over conventional energy sources such as coal and natural gas; however, the U.S. Department of Energy recommends the following ranking for these options (the lower numbers are preferable):

This hierarchy is weighted toward renewable technologies within the building footprint and site. Rooftop PV and solar water heating are the most applicable supply-side technologies for Net Zero Energy Buildings. Other supply-side technologies such as parking lot-based wind or solar energy systems may be available.

The goal in developing the ranking was to encourage technologies that:

• Minimize overall environmental impact by encouraging energy-efficient building designs and reducing transportation and conversion losses

• Will be available over the lifetime of the building

• Are widely available and have high replication potential for future Net Zero Energy Buildings.

There is now a better, more efficient, “pollution free power” and "carbon free energy" solution for cooling, heating and powering homes and commercial buildings where solar energy is available. It's called Solar Trigeneration.

Solar Trigeneration is defined as the simultaneous generation of cooling, heating and power with only the free solar energy from the sun providing the "fuel". 

Solar Trigeneration is now a reality at the Audubon Center at Debs Park several miles from downtown Los Angeles and is one of the world's first "Net Zero Energy Buildings." Net Zero Energy Buildings." Net Zero Energy Buildings."

The Audubon Nature Center is totally powered by the sun’s energy and our Solar Trigeneration energy system!

The 5,300 square foot building operates entirely “grid-free” and without any electric connections to the electric grid, or natural gas connections – a truly sustainable power and energy solution. 

Best of all, the Audubon Center doesn’t rely on the over-burdened electric grid or even natural gas.  Therefore, the Audubon Nature Center NEVER receives an electric bill or natural gas bill.... ever!

The Audubon Nature Center's 5,000 square foot office and conference facility is powered by a Solar Trigeneration system that features a 25-kilowatt solar electric power system where the energy is stored in a bank of batteries. The Center is cooled by a 10-ton solar absorption cooling system powered by an array of very efficient solar heat pipe vacuum tube thermal collectors.  The collectors heat the water to temperatures of 200+ degree F stored in a 1,200 gallon insulated tank, another type of inexpensive battery. The Solar Trigeneration system at the Audubon not only provides the air-conditioning in the summer but also heats the building in the winter, and provides the hot water for the kitchen and bathrooms. 

Absorption chillers, and cooling with solar energy with an absorption chiller are not new technologies.  In fact, absorption chiller technology is over 70 years old.  The first refrigerators were powered by propane gas to run the absorption chillers that used ammonia as a refrigerant.  Electricity and the electric compression chiller gained popularity only because of the convenient “plug and play” appliance and relatively cheap electric rates.  Electricity is no longer economically, or environmentally “cheap.”

History of Cogeneration and Trigeneration

Few people realize that the world's first commercial power plant, designed and built by Thomas Edison, was a cogeneration power plant that was first opened on Pearl Street, in Lower Manhattan, New York.  That was in 1882!  Edison not only generated, and sold electricity in the several blocks surrounding his "Pearl Street Station" but he also sold the hot water that was also generated from the cogeneration plant. The fuel Edison used for generating the electricity and hot water (cogeneration) came from "pulverized coal." The Pearl Street Station provided 110 volts of "direct current" power to 59 customers in lower Manhattan, around his Pearl Street laboratory. 

Cogeneration is the simultaneous production of heat and power. 

Trigeneration is the simultaneous production of cooling, heating and power.

Our company, in partnership with the Renewable Energy Institute and our affiliated partners, have perfected "Solar Cogeneration" and "Solar Trigeneration" which are the "heart" of our Net Zero Energy Buildings.

Unlike traditional cogeneration and trigeneration power plants that are fueled by natural gas - and Thomas Edison's cogeneration plant, which was fueled with pulverized coal, our Solar Cogeneration and Solar Trigeneration energy systems are fueled with the energy of the sun!  And, while natural gas is a "cleaner" fuel, it still has its problems in that it is a limited resource and generates greenhouse gas emissions.  Natural gas also have had extreme price swings and has a history of price volatility.  Natural gas prices have gone from a high of $17.00/mmbtu to a recent low of under $3.00/mmbtu.  

Regarding pulverized coal, yes, it's cheap in terms of the cost of generating electricity, but too many people forget about the "externalities" of pulverized coal that is not reflected in the "cheap" costs of generating electricity from pulverized coal.  These costs not accounted for are the huge environmental cost relating to the use of pulverized coal.  Pound for pound, pulverized coal and coal fired power plants generate more greenhouse gas emissions than any other fossil fuel.  There are also the costs related to the health and safety issues of the miners that mine the coal.  And, the costs to the environment in terms of the ever-increasing amounts of mercury that are "dumped" into the environment from coal fired power plants, is also not reflected in the "cheap" price of generating power from pulverized coal.

Unlike the problems inherently found with the use of fossil fuels, Solar Cogeneration and Solar Trigeneration have no such problems. 

And talk about "cheap" costs of generating power and energy, there is nothing cheaper than free!!!!  

The owners of the Audubon Nature Center never receive any monthly natural gas or electric bills!

And the owners of the Audubon Nature Center will never have to account for their greenhouse gas emissions, or comply with the ever-increasing regulations related to greenhouse gas emissions and the pending Cap and Trade laws..... thanks to our  Solar Trigeneration energy system!

Solar Trigeneration is an EcoGeneration solution.  EcoGeneration refers to a power and energy system that uses the “natural” energy or fuel that is available for a specific site or location. Such energy or fuel includes, solar, wind, BioMethane, geothermal, and ocean power, including ocean tidal and ocean thermal energy conversion. For example, in the desert areas of the Southwestern U.S. , there is an abundance of solar energy. Therefore, home-owners and business owners in this part of the country should seriously consider an EcoGeneration system (“ecogen system”) that optimizes the opportunities available through solar energy

Today, the cause of the summer peak electric demand, electric supply problems, and black-outs, are the result of the energy crisis in California, primarily attributed to the air conditioning load. Over 40 percent of the electricity generated every day goes is used for air conditioning.  At this time of year, the electric utilities are forced to turn on all of their power plants to generate the “peak” demands required by the customers, primarily for air-conditioning.  This means that all of the efficient power plants, the inefficient power plants, along with all of the “peaking” power plants have to run to generate the electricity needed. The high cost of meeting the peak demand is passed on to the consumers with rates of $.20+ per kWh during the summer months. For fixed income seniors living in desert communities, they are already forced to conserve on energy, food, water, and other necessities of life. 

Greater Demands on California’s Limited Electric Supply, Lack of New Electric Power Supplies, and This Summer’s Heat Wave are Compounding the Problem Leading to the “Perfect Electric Storm”

Many people will remember the movie “The Perfect Storm” from several years ago, when several storms came together in the northeastern part of the U.S. to produce a deadly and catastrophic “perfect” storm. Today, a different type of “perfect storm” is brewing in California. The storm that’s looming on the horizon in California is a “perfect electric storm” wherein the supply of electricity from the electric utility company’s power plants are unable to keep-up with the demand – meaning a black-out, or loss of electricity, like the black-outs from previous years, and like the northeastern black-out from 2003.

The most likely time of year for a black-out in California, unfortunately, is the summer, when air-conditioners are running at the maximum, and placing the maximum load on California’s electricity supply.  Should such a black-out occur in the desert areas of California, where daily high temperatures routinely reach 110 degrees and higher, and where a significant percentage of the population is comprised of retired and senior citizens, and should the black-out be prolonged, a number of deaths will be the likely outcome. People, and especially the elderly, simply cannot tolerate prolonged high temperatures

How Do We Prevent the “Perfect Electric Storm” from Occurring in California and Other Regions in the U.S.?

Another major concern is how do we prevent the “Perfect Electric Storm” from happening, like the Northeast Blackout several summers ago, especially for people living in the desert?  California ’s energy authorities are warning of a possible energy crisis during the hot summer months, due to the excessive and prolonged summer temperatures where demand increases by over 40 percent.  Compounding the problem is the rising demand for electricity due to population growth and the limited transmission capacity in some areas in the region.  According to the California Energy Commission, the State must build three natural gas-fired 500-megawatt peaking power plants, every year, just to keep up with the growing demands of electricity. Failure to keep up with demand means The problem is getting worse due to the population growth in the Inland Empire , Coachella Valley and Antelope Valley. The projected power gap for the coming summers remains bleak.

Governor Schwarzenegger’s “Million Solar Roofs” program and the passage of the 2005 Federal Energy Act will be the foundation to create a “Perfect Solar Storm” to trigger the Solar Economy throughout California. 

With the threat of California’s seniors and elderly dying from heat exhaustion due to power outages, black-outs, rolling black-outs and the rising costs of electricity and natural gas, combined with the continuing impact of global warming, the perfect solution is to create a Solar Revolution by cooling, heating and powering the desert with solar energy and technologies like Solar Cogeneration or Solar Trigeneration.

Absorption Chillers 
&
Adsorption Chillers

For Solar Trigeneration Applications

What Absorption Chillers and How Does They Work?

Absorption chillers use heat instead of mechanical energy to provide cooling. A thermal compressor consists of an absorber, a generator, a pump, and a throttling device, and replaces the mechanical vapor compressor.

In the chiller, refrigerant vapor from the evaporator is absorbed by a solution mixture in the absorber. This solution is then pumped to the generator. There the refrigerant re-vaporizes using a waste steam heat source. The refrigerant-depleted solution then returns to the absorber via a throttling device. The two most common refrigerant/ absorbent mixtures used in absorption chillers are water/lithium bromide and ammonia/water.

Compared with mechanical chillers, absorption chillers have a low coefficient of performance (COP = chiller load/heat input). However, absorption chillers can substantially reduce operating costs because they are powered by low-grade waste heat. Vapor compression chillers, by contrast, must be motor- or engine-driven.

Low-pressure, steam-driven absorption chillers are available in capacities ranging from 100 to 1,500 tons. Absorption chillers come in two commercially available designs: single-effect and double-effect. Single-effect machines provide a thermal COP of 0.7 and require about 18 pounds of 15-pound-per-square-inch-gauge (psig) steam per ton-hour of cooling. Double-effect machines are about 40% more efficient, but require a higher grade of thermal input, using about 10 pounds of 100- to 150-psig steam per ton-hour.

In single-effect absorption chillers, all condensing heat cools and condenses in the condenser. From there it is released to the cooling water. A double-effect machine adopts a higher heat efficiency of condensation and divides the generator into a high-temperature and a low-temperature generator.

Actions You Can Take

Determine the cost-effectiveness of displacing a portion of your cooling load with a waste steam absorption chiller by taking the following steps:

• Conduct a plant survey to identify sources and availability of waste steam

• Determine cooling load requirements and the cost of meeting those requirements with existing mechanical chillers or new installations

• Obtain installed cost quotes for a waste steam absorption chiller

• Conduct a life cycle cost analysis to determine if the waste steam absorption chiller meets your company's cost-effectiveness criteria.

Absorption Chillers Refrigeration Cycle

The basic cooling cycle is the same for the absorption and electric chillers. Both systems use a low-temperature liquid refrigerant that absorbs heat from the water to be cooled and converts to a vapor phase (in the evaporator section). The refrigerant vapors are then compressed to a higher pressure (by a compressor or a generator), converted back into a liquid by rejecting heat to the external surroundings (in the condenser section), and then expanded to a low- pressure mixture of liquid and vapor (in the expander section) that goes back to the evaporator section and the cycle is repeated.

The basic difference between the electric chillers and absorption chillers is that an electric chiller uses an electric motor for operating a compressor used for raising the pressure of refrigerant vapors and absorption chillers use the heat for compressing refrigerant vapors to a high-pressure. The rejected heat from the power-generation equipment (e.g. turbines, microturbines, and engines) may be used with an absorption chiller to provide the cooling in a CHP system.

The basic absorption cycle employs two fluids, the absorbate or refrigerant, and the absorbent. The most commonly fluids are water as the refrigerant and lithium bromide as the absorbent. These fluids are separated and recombined in the absorption cycle. In the absorption cycle the low-pressure refrigerant vapor is absorbed into the absorbent releasing a large amount of heat. The liquid refrigerant/absorbent solution is pumped to a high-operating pressure generator using significantly less electricity than that for compressing the refrigerant for an electric chiller. Heat is added at the high-pressure generator from a gas burner, steam, hot water or hot gases. The added heat causes the refrigerant to desorb from the absorbent and vaporize. The vapors flow to a condenser, where heat is rejected and condense to a high-pressure liquid. The liquid is then throttled though an expansion valve to the lower pressure in the evaporator where it evaporates by absorbing heat and provides useful cooling. The remaining liquid absorbent, in the generator passes through a valve, where its pressure is reduced, and then is recombined with the low-pressure refrigerant vapors returning from the evaporator so the cycle can be repeated.

Absorption chillers are used to generate cold water (44°F) that is circulated to air handlers in the distribution system for air conditioning.

"Indirect-fired" absorption chillers use steam, hot water or hot gases steam from a boiler, turbine or engine generator, or fuel cell as their primary power input. Theses chillers can be well suited for integration into a CHP system for buildings by utilizing the rejected heat from the electric generation process, thereby providing high operating efficiencies through use of otherwise wasted energy.

"Direct-fired" systems contain natural gas burners; rejected heat from these chillers can be used to regenerate desiccant dehumidifiers or provide hot water.

Commercially, absorption chillers can be single-effect or multiple-effect. The above schematic refers to a single-effect absorption chiller. Multiple-effect absorption chillers are more efficient and discussed below.

Multiple-Effect Absorption Chillers

In single-effect absorption chillers, the heat released during the chemical process of absorbing refrigerant vapor into the liquid stream, rich in absorbent, is rejected to the environment. In a multiple-effect absorption chiller, some of this energy is used as the driving force to generate more refrigerant vapor. The more vapor generated per unit of heat or fuel input, the greater the cooling capacity and the higher the overall operating efficiency.

Double-effect absorption chillers uses two generators paired with a single condenser, absorber, and evaporator. It requires a higher temperature heat input to operate and therefore they are limited in the type of electrical generation equipment they can be paired with when used in a CHP System.

Triple-effect absorption chillers can achieve even higher efficiencies than the double-effect chillers. These absorption chillers require still higher elevated operating temperatures that can limit choices in materials and refrigerant/absorbent pairs. Triple-effect chillers are under development by manufacturers working in cooperation with the U.S. Department of Energy.

What are Thin Film Photovoltaics?

Without a doubt, the most exciting technology in the solar power industry is "Thin Film Photovoltaics."  Thin Film Photovoltaics technology represents the next big thing in renewable energy and solar power as it integrates nanotechnologies into the production of solar photovoltaics. 

According to the Department of Energy, the recent technological advances in thin film photovoltaics make this a very exciting time to be in the solar energy industry.  These advances have led to many new developments in the components and manufacturing of thin film photovoltaics. This has made thin film photovoltaics cheaper to manufacture as they are also now easier to install since they are extremely versatile, flexible, bendable, and much lighter.

Thin film photovoltaics  have led many to believe that as much as 50% of our nation's future power will be generated by "power buildings" that integrate "building integrated photovoltaics" or "BIPV" into the building's skin or exterior surfaces, that convert sunlight into "pollution free power" for use in the building.  This also designates these buildings (and homes) as "Net Zero Energy Buildings" and make the option for going grid-free, or not connecting to the grid, a real possibility.

According to the Department of Energy, the market potential for printed electronics will grow into a $47 billion market by 2018.  Thin film photovoltaics represents a significant portion of this market - and based on this heavily researched solar technology, thin film photovoltaics now represents a $20 billion/year industry in the U.S.

The solar PV panels produced under the thin film photovoltaics umbrella have the potential to produce power significantly cheaper power than today’s typical silicon-based PV panels.  The panels are usually made in the form of a monolithic piece of glass, upon which various thin films are deposited, although a number of firms are working on depositing the materials on a substrate, such as stainless steel or plastic.

Types of Thin Film Photovoltaics – there are primarily three types of thin film photovoltaics and include:

1. Amorphous Silicon

2. Cadmium Telluride

3. Copper Indium Gallium Diselenide

Amorphous Silicon had the largest share of the thin film photovoltaics market through 2006. It has been researched for the longest period of time, may be the best understood material of the three and has been commercial for the longest. Cadmium Telluride, a very toxic chemical and has the remaining share and is growing. 

• Lower cost of production of the 

• Lower production facility cost per watt - CapEx

• Uses as little as 1/500 of the amount used in standard silicon cells

• Lower energy payback – amount of time until the product produces more energy than was utilized in its manufacture.

• Produces more power/watt

• Superior performance in hot and cloudy climates

• Integrates seemlessly in homes and buildings – see Building Integrated Photovoltaics 

• Produces the lowest cost power

Biomethane: the Perfect Renewable Fuel!
Biomethane Far Better than B100 Biodiesel or E100 Ethanol

As Biomethane is a near perfect fuel, and since Biomethane represents the best of all biofuels in terms of Recycling Carbon, and has the highest Net Energy Balance, and as Biomethane technologies such as Anaerobic Digesters and Biomass Gasification development increases and becomes even more commonplace, one of the fundamental questions is: what is the size of the potential biomass resource supply in the U.S.?

In April 2005, the DOE and the U.S. Department of Agriculture (USDA) co-published a report assessing the potential of the land resources in the U.S. for producing sustainable biomass: Biomass as Feedstock for a Bioenergy and Bioproducts Industry: The Technical Feasibility of a Billion-Ton Annual Supply. Looking at forestland and agricultural land, the two largest potential biomass sources, this study estimates that the U.S. can sustainably produce up to 1.3 billion tons of biomass feedstock by mid-century. This would be enough feedstock to produce 60 billion gallons of B100 Biodiesel and E100 Ethanol with today's technologies.

This study doesn't address the opportunities for Biomethane production from biomass feedstock or Biomass Gasification technologies. Some recent estimates indicate that Biomethane could replace up to 50% of present natural gas consumption in the U.S. and in some countries, such as Iceland, Biomethane already provides 100% of the natural gas requirements.

There are many assumptions in the Billion Ton Study report that impact these estimates, but we believe the estimates reasonably reflect the potential availability and impact of biomass resources.

Of the total estimated resource, the study suggests that forestlands in the contiguous United States can produce approximately 368 million dry tons annually. This projection includes 52 million dry tons of fuelwood harvested from forests and woodlands, 145 million dry tons of residues from wood processing mills and pulp and paper mills, 47 million dry tons of urban wood residues including construction and demolition debris, 64 million dry tons of residues from logging and site clearing operations, and 60 million dry tons of biomass from fuel treatment operations.

Biomass to Biofuels

By "converting" biomass wastes – such as municipal solid waste, sewage sludge, crop residues, energy crops, and manure – into biofuels, this will resolve the energy, environmental and political problems in an economical and environmentally sound manner - that will produce over one million new jobs.

According to Jeff Seisler, Director of the European Natural Gas Vehicle Association, "Biomethane has an outstanding potential as a multifaceted solution to multifaceted social problems: urban and agricultural waste management, water purification, and clean air. Urban and agricultural waste can be processed into usable methane, as can the sewage during the water purification process. Cleaning and compressing the gas for use in vehicles then provides cleaner air than petroleum-consuming vehicles."

Continuing, Mr. Seisler states about Biomethane; "this environmental 'closed loop waste-to-energy-to-fuel used in vehicles that again truck the next load of waste to the energy processing plants-substitutes fossil fuels with a renewable resource and reduces greenhouse gases 100% as compared to over gasoline vehicles (on a well-to-wheel basis).

According to Peter Boisen Chairman, of ENGVA, "various well respected European research institutes now estimate more than three times better fuel output per hectare of land used than if going for ethanol or biodiesel. Sweden currently has a 51% Biomethane share, and Switzerland 37%. France, Norway, Germany and Austria use smaller amounts for vehicles. Iceland, completely without natural gas, uses 100% biomethane in its NGVs," Boisen says.  Continuing, Boisen adds, "China, India, Korea, the Ukraine, Spain and Italy are other examples of countries now starting up projects where Biomethane will be used as a vehicle fuel." 

"With the energy efficiency of the gas production process at 50% to 70% it's hard to think of a more socially acceptable and economic energy value for the transportation sector," Boisen says.

"Governments need to get out of their liquid fuel paradigm to refocus and balance their policies and communications to support the development of a Biomethane infrastructure. In Europe Biomethane has the potential to replace 20% of the petroleum consumed in the transport sector by 2030."

Thursday, 29 June 2006
Sacramento, California USA and Sweden 

In a ceremony held at the Ministry of the Environment in Stockholm, representatives of the Kingdom of Sweden and the State of California signed an agreement pledging the two governments and their related industries to work together to develop bioenergy, with a particular emphasis on Biomethane. 

“Through a strong working relationship between its industry and government, Sweden is showing how bioenergy can be developed in a cost-effective manner that benefits its economy and environment. We are extremely pleased to have signed this Memorandum of Understanding (MOU) that will provide a basis for intensified collaboration between Swedish and California officials to develop a thriving bioenergy industry in California,” said Joe Desmond, Undersecretary for the California Resources Agency.

In particular, Sweden has been a global leader in terms of converting biowaste, largely agricultural material and residues, into usable Biomethane. This gas is then used to either generate electricity, residential heating, or as a transportation fuel.

More than 8,000 vehicles in Sweden are powered by a combination of natural gas and Biomethane. The vehicles include transit buses, refuse trucks, and more than 10 different models of passenger cars. There are more than 25 Biomethane production facilities in Sweden and 65 filling stations. The Swedish Biomethane industry has been growing at an annual rate of about 20 percent over the last five years.

According to the Swedish Gas Association, more than 50 percent of the methane used to power Sweden’s natural gas vehicles now comes from biological sources, up from 45% last year. Natural gas vehicle sales in Sweden are increasing at the rate of 25% per annum. 

Sweden was motivated to develop its Biomethane industry because it has no natural gas reserves, to more efficiently manage its waste, and to meet its obligations under the Kyoto Accord. Since Biomethane is developed from methane sources that would normally release into the atmosphere, it’s considered one of the most climate friendly fuels. Methane (and Biomethane) is 21 times more reactive as a greenhouse gas than carbon dioxide (CO2). Sweden is currently meetings its objectives and schedule as outlined in the Kyoto accord.

Biomethane is developed by heating up and breaking down biomaterials in an (Anaerobic Digesters) digester. Among other raw materials, Swedish operators feed their Anaerobic Digesters with slaughterhouse waste, swine manure, and even grassy crops. After the materials breakdown over a 20 day period, technology is then used to remove the impurities and produce Biomethane. Once cleaned-up, Biomethane is 98 percent methane and easily meets the Swedish and California pipeline standards.

The Memorandum of Understanding can be accessed on the California Resources Agency Web site: http://resources.ca.gov/press_documents/CaliforniaSwedenBiofuelsMOU.pdf

________________________________________________________

Anaerobic Digesters recover valuable and toxic Biomethane from organic materials and prevents the Biomethane - which has a Global Warming Potential that is 21 times more harmful to our climate than Carbon Dioxide Emissions - from entering the atmosphere.  

Biomethane, which we also refer to as "Renewable Natural Gas" is used as a renewable fuel for our cogeneration and trigeneration power plants. Alternatively, we may sell the Biomethane to a customer and transport it to them from our Anaerobic Digesters via natural gas pipelines.

We believe Anaerobic Digesters and Biomethane represent exciting opportunities for generating renewable natural gas and profits - for multiple reasons:

1.  Anaerobic Digesters take an existing liability and waste (Biomethane) and convert it into an asset and " profit generator."

2.  Anaerobic Digesters mitigate and reverse climate change and global warming by preventing Biomethane to escape into the atmosphere, which is one of the major causes of climate change and global warming.  

Of all Greenhouse Gas Emissions, Biomethane is 21 times more harmful to the environment than Carbon Dioxide Emissions.

3.  Anaerobic Digesters are vital for renewable energy production and helping our country's drive for energy independence. 

4.  EVERY wastewater treatment plant as well as ALL Concentrated Animal Feeding Operations (CAFO's) - IN EVERY COUNTRY - will soon be installing Anaerobic Digesters to prevent Biomethane from entering the atmosphere and help reverse climate change as well as for use as a renewable fuel. Or, they will be replacing their existing inefficient and inferior mechanical wastewater treatment plants, with our "Natural Wastewater Treatment" plants! 

5.  The country of Sweden is the global leader in Biomethane production.  Sweden has identified the Biomethane opportunities and is converting biowaste derived from agricultural material and residues into usable Biomethane. The Biomethane is used to generate clean, renewable electricity, residential heating, and also as a transportation fuel. Biomass sources make up 45% of Sweden’s Biomethane.  Sweden's Biomethane industry has been growing at an annual rate of around 20% over the last five years.  Biomethane powers more than 8,000 transit buses, garbage trucks, and 10 different models of passenger cars in Sweden. Sweden now has more than 25 Biomethane production facilities and 65 filling stations. The country believes that since Biomethane is developed from natural, organic sources that would have been released into the atmosphere, that Biomethane is considered one of the most climate-friendly fuels. Biomethane is 98% methane and easily meets the Swedish and California pipeline standards.
