Combined Heat and Power Projects
Combined heat and power (CHP) is the sequential production of electricity and useful thermal energy from a single source fuel.
- Types of CHP generators:
- Gas Internal Combustion Engine
- Gas Combustion
- Turbine Microturbine
- Fuel types:
- Natural Gas
- Biogas
- Landfill Gas
- Useful thermal energy is created from the production of electricity which would otherwise be wasted if not used for other nonelectric generation, beneficial purposes such as:
- Hot Water
- Heating
- Cooling
- Other industrial processes
CHPs can qualify for Tier II AECs in the PA AEPS under the distributed generation designation (DGN). The PA AEPS does not limit the number of years a CHP can participate. To qualify in the AEPS, CHPs will need to meet the following requirements:
- Located in Pennsylvania
- Total capacity less than 5 MW
- Interconnection to local utility (if not interconnected, the generator may still qualify under demand-side-management)
- Production meter to record generation
- Currently, the PA AEPS does not have a system efficiency requirement
Please see the CHP Overview for additional information and application directions.
