Power Purchase Agreements

What are Power Purchase Agreements?

A Power Purchase Agreement or "PPA" 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 for a CHP system, solar cogeneration or rooftop PV energy solution, may save your company thousands, and possibly hundreds of thousands of 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 most energy, renewable energy and power generation projects, you need to insure that the PPA is an optimum agreement that you/your company can live with over the 10-20 year period. Note: We are not attorneys and do not provide legal advice but we do work with several attorneys and law firms that have a record of providing PPA's that have secured project financing.

Clean Power Generation

Running on "green fuel" such as Biomethane, B100 Biodiesel, Synthesis Gas or natural gas, our CHP Systems are the greenest "clean power generation" systems available.

With Natural Gas at approximately $4.00/mmbtu, our Clean Power CHP Systems  generate power for about $0.04 / kWh (fuel cost).

With operations & maintenance added, that's  about 5.5 cents /kWh - or approximately 50% - 60% less than what most commercial customers are paying, on average, for their electricity.

CHP Systems
(Cogeneration and Trigeneration) Plants 
Have Very  High Efficiencies, Low Fuel Costs & Low Emissions

The CHP System below is rated at 900 kW with a 
heat rate of 4100 btu/kW & system efficiency of 92%.

The CHP System below features: (2) Natural Gas Engines @ 450 kW each 
on one skid with optional Selective Catalytic Reduction system 
which removes Nitrogen Oxides to "non-detect."




CHP Systems and Dispersed Generation power plants are an ideal solution for data centers, district energy systems electric utilities, electric co-ops, electrical sub-stations, energy service companies, food processing plants, hospitals, military bases and  universities among many others. 

High-efficiency CHP Systems eliminate blackouts, electric grid supply problems and significantly reduce greenhouse gas emissions and hazardous air pollutants associated with electric power generation at central power plants.

A CHP System may be the best solution for your company's economic and environmental sustainability as we "upgrade" natural gas to clean power with our clean power generation solutions. Our emissions abatement solutions reduce nitrogen oxides (NOx) to "non-detect" and can be installed and operated in most EPA non-attainment regions!

What is "Decentralized Energy"?

Decentralized Energy is the opposite of "centralized energy."  

Decentralized Energy energy generates the power and energy that a residential, commercial or industrial customer needs, onsite. Examples of decentralized energy production are natural gas fueled CHP Systems, Rooftop PV and solar cogeneration energy systems.

Today's electric utility industry was "born" in the 1930's, when fossil fuel prices were cheap, and the cost of wheeling the electricity via transmission power lines, was also cheap.  "Central" power plants could be located hundreds of miles from the load centers, or cities, where the electricity was needed. These extreme inefficiencies and cheap fossil fuel prices have added a considerable economic and environmental burden to the consumers and the planet.

Centralized energy is found in the form of electric utility companies that generate power from "central" power plants. Central power plants are highly inefficient, averaging only 33% net system efficiency.  This means that the power coming to your home or business - including the line losses and transmission inefficiencies of moving the power - has lost 75% to as much as 80% energy it started with at the "central" power plant.  These losses and inefficiencies translate into significantly increased energy expenses by the residential and commercial consumers.

Decentralized Energy
is the Best Way to Generate Clean and Green Energy! 

How we make and distribute electricity is changing! 

The electric power generation, transmission and distribution system (the electric "grid") is changing and evolving from the electric grid of the 19th and 20th centuries, which was inefficient, highly-polluting, very expensive and “dumb.”  

The "old" way of generating and distributing energy resembles this slide:


The electric grid of the 21st century (see slide below) will be Decentralized, Smart, Efficient and provide "carbon free energy" and "pollution free power” to customers who remain on the electric grid.  Some customers will choose to dis-connect from the grid entirely.  (Electric grid represented by the small light blue circles in the slide below.)

Typical "central" power plants and the electric utility companies that own them will either be shut-down, closed or go out of business due to one or more of the following:  failed business model, inordinate expenses related to central power plants that are inefficient, excessive pollution/emissions, high costs, continued reliance on the use of fossil fuels to generate energy, and the failure to provide efficient, carbon free energy and pollution free power

 Carbon free energy and pollution free power can also reduce our dependence on foreign oil while making us "energy independent" and reducing or eliminating Greenhouse Gas Emissions.

What is "Cogeneration"?

Did you know that 10% of our nation's electricity now comes from "cogeneration" plants?

And because cogeneration is so efficient, it saves its customers up to 40% on their energy expenses, and provides even greater savings to our environment through significant reductions in fuel usage and much lower greenhouse gas emissions.

Cogeneration - also known as combined heat and power (CHP), cogen, district energy, total energy, and combined cycle, is the simultaneous production of heat (usually in the form of hot water and/or steam) and power, utilizing one primary fuel such as natural gas, or a renewable fuel, such as Biomethane, B100 Biodiesel, or Synthesis Gas.

Cogeneration technology is not the latest industry buzz-word being touted as the solution to our nation's energy woes. Cogeneration is a proven technology that has been around for over 120 years!

Our nation's first commercial power plant was a cogeneration plant that was designed and built by Thomas Edison in 1882 in New York. Our nation's first commercial power plant was called the "Pearl Street Station."


Net Zero Energy


"Net Zero Energy" to Become $1.3 Trillion/year Industry by 2035

What is Net Zero Energy?

Net Zero Energy - when applied to a home or commercial building, simply means that they generate as much power and energy as they consume, when measured on an annual basis.

"Central power plants" - which have been the typical method of providing electricity for customers - are highly inefficient and are only 28% to 40% efficient. This means that central power plants waste about 60% - 72% of the energy in the form of "waste heat" electrical and mechanical inefficiencies. In addition, enormous amounts of hazardous air pollutants, volatile organic compounds, nitrogen oxides, mercury and greenhouse gas emissions are unnecessarily spewed into the environment by these central power plants.  The electric grid, where the "brown power" generated from the central power plants is distributed to "load centers" which is comprised of the local electric utility's customers - homes and businesses - is also highly inefficient and wasteful of vast amounts of energy.

Under the American Energy Plan, central power plants are no longer needed as all of the clean power and energy is generated where the power and energy is needed - at your home or business.  The clean power and energy is produced through "distributed energy resources" such as "solar cogeneration" or "solar trigeneration" energy systems that are highly-efficient producing. These homes and businesses will become "central power plants" and if the homeowners and business owners choose, they may completely dis-connect from the electric grid. 

The U.S. Army now has a Net Zero Energy initiative to help reduce/eliminate America's use of foreign oil  - particularly oil from muslim/middle-east countries - which saves the lives of our brave soldiers in the military.

Net Zero Energy Buildings Are Coming - What About The Buildings Already Standing?



What is Trigeneration?

Trigeneration is the simultaneous production of three forms of energy - typically, Cooling, Heating and Power - from only one fuel input. 

Stated another way, our trigeneration power plants produce three different types of energy for the price of one.

Trigeneration energy systems now exceed the efficiency of central power plants by almost 300% as overall trigeneration system efficiency is about 90%. Typical "central" power plants, that do not need the heat generated from the combustion and power generation process, are only about 33% efficient. 

Basically, a trigeneration power plant is a cogeneration power plant that has added absorption chillers for producing chilled water from the heat that would have been wasted from a cogeneration power plant. 

In addition to the economic benefits and advantages, trigeneration plants reduce our dependence on foreign energy supplies and help our environment by dramatically reducing greenhouse gas emissions such as carbon dioxide - when compared to typical power plants. Trigeneration has been hailed the "hat-trick of the energy industry" with system efficiencies approaching and exceeding 90%.

Trigeneration plants are very energy efficient, conserve natural resources and reduce fuel consumption as the system operates at such high efficiencies. Cogeneration and trigeneration power plants are about 90% efficient and approximately 300% more efficient than "central power plants" that average 27% to 40% efficiency. When fueled with renewable fuel, cogeneration and trigeneration plants are carbon neutral, producing no greenhouse gas emissions and the optimum solution for clients seeking to reduce their energy expenses and greenhouse gas emissions.

What is "Net Positive Energy?"

Net Positive Energy - when applied to a home or commercial building, means the home or business generates more power and energy than they consume, when measured on an annual basis.  The excess power and energy can then be sold/transferred/exported to the grid or to their surrounding neighbors in order to off-set and eventually replace the "dirty brown electrons" generated from highly polluting and inefficient "central power plants."

What is a "Positive Energy Building?"

Net Positive Energy - A "positive energy building" produces more energy (from renewable energy sources) than it consumes.  This surplus energy can then be sold to produce an income to a neighbor or exported to the electric grid for revenue or a credit (see Net Energy Metering).

About us

The founder of the Renewable Energy Institute (REI) was first involved in Net Zero Energy buildings and Solar Trigeneration sm energy system in 2001 - 2002.  This started with family-owned real estate developments in Northern and Southern California.  This interest was accelerated when REI's founder was introduced to the President of a solar company in Los Angeles and their client, the Audubon Nature Center at Deb's Park (Los Angeles) that was planning to build a new 5,000 sf office and conference center. Except, the new building for the Audubon Nature Center was about 1/2 mile from the end of the power lines and a very costly extension of the power lines to their new facility forced them to consider a solar solution. When the Audubon Nature Center's new 5,000 sf office and conference center was completed in 2003, the facility not only featured the Solar Trigeneration sm energy system - they were awarded one of the first Platinum LEED Awards by the USGBC - and the powerlines were still 1/2 mile away! To this day, 100% of the power and energy for the Audubon Nature Center's building is supplied by the Solar Trigeneration sm energy system - whether at 12 noon, or 12 midnite.  (The Audubon's facility also includes a battery energy storage system for back-up power generated by the Rooftop PV panels as well as a thermal energy storage system that stores the excess hot water generated by the evacuated tube collectors).

These early projects led to more client inquiries and engagements with real estate developers, architects and building owners in Southern California, Louisiana and Texas and the advent of a growing Net Zero Energy industry along with Solar Cogeneration sm  & Solar Trigeneration sm energy systems. This culminated in a family-owned 200 (Net Zero Energy) home real estate development in Desert Hot Springs which has been approved but not yet constructed. 

During this time, the REI's Founder became a volunteer and Advisor to the University of Texas' Solar Decathlon Competition. He coordinated the donation of the same solar thermal system used at the Audubon Nature Center's facility in Los Angeles, for UT's entry in the 2002 Solar Decathlon Competition in Washington, D.C.  UT's entry in the Solar Decathlon Competition placed 1st in the domestic hot water competition that year (2002) and 4th overall, out of 20 universities that had entered. 

In 2006, after Hurricane Kattrina devastated New Orleans, the REI was formed and several of the REI's board members and a Professor from the University of Texas School of Architecture formed a design team to enter the Brad Pitt/Global Green Rebuild New Orleans Competition.  Our entry also focused on sustainable building solutions and materials as well as the Net Zero Energy concepts, incorporating once again, a Solar Trigeneration sm energy system. 

Today, the REI "Flagship" has chartered the Renewable Energy Institute in Florida, with discussions to open REI state chapters in Arizona, California, Hawaii, Minnesota and Oregon. 

The REI supports greater use of Net Zero Energy systems by architects, builders, homeowners and owners of commercial buildings. This includes "upgrading" homes and commercial buildings to Net Zero Energy.  The REI provides Net Zero Energy; advertising, business development, conferences, e-commerce, education, marketing, online marketing, public relations, renewable energy, sales and strategic marketing solutions for architects, builders, cities, colleges, HVAC contractors, Net Zero Energy developers, real estate developers and universities.

“spending hundreds and hundreds and hundreds of billions of dollars every year for oil, much of it from the Middle East, is just about the single stupidest thing that modern society could possibly do. It’s very difficult to think of anything more idiotic than that.” 
~ R. James Woolsey, Jr., former Director of the CIA

Price of Addiction
to Foreign Oil

According to R. James Woolsey, for Director of the Central Intelligence Agency, “The basic insight is to realize that global warming, the geopolitics of oil, and warfare in the Persian Gulf are not separate problems — they are aspects of a single problem, the West’s dependence on oil."
