District Energy System

What is a District Energy System?

A District Energy System distributes power and energy from the facility's trigeneration energy system through the facility's (campus, downtown area, etc.) underground pipes to the buildings connected to the system. Individual buildings connected to the system, therefore, do not need boilers, chillers or cooling towers. 

Customers use the hot water and chilled water to meet their space heating, water heating, processing and air-conditioning needs. Once the energy (hot water, steam and chilled water) are "used" by the individual buildings, the water is returned to the central plant which is then either re-heated and/or re-chilled… and then re-circulated throughout the underground, closed-loop pipes of the District Energy System. 

District Energy, or, "trigeneration" plants at about 90% system efficiency, are about 300% more efficient and environmentally-friendly than typical, "central" power plants. Trigeneration plants are an excellent and ideal energy and power solution for multiple building locations such as;


Clean Power Generation Solutions

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

The Effective Heat Rate is Approximately
4100 btu/kW & System Efficiency is 92% Plant.

The CHP System below is Rated at 900 kW and Features:
(2) Natural Gas Engines @ 450 kW each on one Skid with Optional
Selective Catalytic Reduction
system that removes Nitrogen Oxides to "non-detect."

Our CHP Systems (available in either cogeneration or trigeneration) 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 to "non-detect" which means our CHP Systems can be installed and operated in most EPA non-attainment regions!


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 "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.)
