Combined Heat and Power

Complimentary to GCE's expertise in landfill gas to energy systems is our work with combined heat and power systems. Where conventional power systems remain in the range of 35 to 40 percent efficiency, by utilizing the waste heat generated during the production process the efficiency of a combined heat and power system may be as much as 80 percent.

Also of paramount interest to our clients is taking concrete steps to improve the environment we all live in.  GCE and our clients truly form a bonding relationship as we work together to enhance the world for future generations.

GCE professionals can successfully take you through the development process.  This process typically consists of a feasibility study, economic analysis, financing, permitting, engineering design, construction, construction management, commissioning, and operations and maintenance services.
A summary of some of the more important considerations that are initially evaluated are as follows:

Fuel Source
In many instances, a CHP system is designed to utilize biogas that is derived from a landfill, wastewater treatment plant, or other type of digester. A consistent and clean fuel source is vital to the economic performance of the system.  GCE can evaluate your fuel stream with regards to reliability and can also evaluate and design gas conditioning systems to prolong the life of the critical and expensive engine and heat exchange components.

Fuel to Power Systems 
The following are the fuel to power systems GCE has worked with:

-     Internal Combustion Reciprocating Engines
-     Microturbines
-     Fuel Cells
-     Gas Turbines

The selection of the appropriate engine is an important consideration in the design of the combined heat and power system. GCE has assisted clients in the selection of the appropriate engine based on the type and variability of fuel in-puts, the environmental regulations in which the project is situated, and the overall economics of the project.  GCE has a very good working relationship with the various engine manufacturers.

Utility Interconnection
GCE has experience working in many locations throughout the United States on working with public and private utilities on obtaining utility interconnection approvals.  Many times, this step in the process is one of the most time consuming and costly part of the development process.

Greenhouse gas emmisions is an ever more important aspect of any project.  GCE professionals will walk you through the steps to evaluate what the estimated impact to your existing permits are, or what will be required to obtain new permits.
