Additional Distributed Energy Resource Technologies

DER technologies include Combined Heat and Power (CHP), Waste Heat to Power, Linear Generator, Power to Gas, Battery Storage, and Solar Photovoltaic.

Combined Heat and Power (CHP) Technologies

CHP  are technologies that generate electricity and capture the heat that would otherwise be wasted to provide useful thermal energy—such as steam or hot water—that can be used for space heating, cooling, domestic hot water, and industrial processes.




How is CHP powered?

In California, a CHP system can be powered from natural gas, renewable natural gas, biogas and/or hydrogen in technologies such as engines, turbines, microturbines, or even fuel cells. A CHP system could be comprised of an internal-combustion engine generator, a micro-turbine, a gas turbine, a steam turbine, a fuel cell and heat recovery equipment.

How does a CHP unit generate electricity and heat?

These systems simply capture and utilize excess heat generated during the production of electric power. CHP systems offer economic, environmental, and reliability-related advantages as compared to conventional power generation facilities that produce only electricity. Distributed power generation systems, which are frequently located near thermal loads, are particularly well suited for CHP applications.

What is the benefit of CHP?

  • Increased energy efficiency
  • Reduced air emissions
  • Enhanced grid reliability and resilience
  • Reduced energy and infrastructure costs

What are the applications of CHP?

  • Commercial buildings - office buildings, hotels, health clubs, nursing homes
  • Residential - condominiums, co-ops, apartments, planned communities
  • Institutions - colleges and universities, hospitals, prisons, military bases
  • Municipal—district energy systems, wastewater treatment facilities, K-12 schools
  • Manufacturers—chemical, refining, ethanol, pulp and paper, food processing, glass manufacturing.

What is MicroCHP?

MicroCHP is an extension of the idea of traditional CHP to the smaller customer sector range, in the range up to 50 kW. The difference between MicroCHP and CHP is the scale of the system, as traditional CHP systems are typically larger.
