The US Department of Energy (DOE)’s Advanced Manufacturing Office has announcd the release of the updated Combined Heat and Power (CHP) Installation Database in the country.
The database contains a comprehensive listing of combined heat and power installations throughout the US. The latest update shows there are 82.6 GW of CHP installed at nearly 4,400 sites around the country.
The updated database, sponsored by the US Department of Energy and maintained by ICF Inc, includes data as of December 31, 2016 and is designed to make navigation easy for visitors to the website, allowing users to:
- Search for specific CHP systems or groups of systems.
- Sort and filter data by categories such as application (building/facility) or fuel type.
- Download a list of the currently operating CHP systems in the database as well as a set of summary tables for the data. In order to access the data for download, the user must register by setting up a username and password.
- Send an email to provide any information about operating CHP systems in the U.S.
Since the last update data shows an increase in the overall US CHP capacity, from 81.1 GW in 2015 to 82.6 GW in 2016. The number of CHP sites grew from 4,309 to 4,395 in 2016. This growth was fuelled by the 173 new CHP installations that were entered into the database in 2016.
These installations were spread throughout the U.S., with new systems in 34 states and the District of Columbia. The states with the most new CHP installations were New York (39), Massachusetts (27), California (19), and Pennsylvania (11).
Many of the former installations were older, larger inefficient systems. But now, many of the new installations are located at commercial and institutional sites, thus continuing the move toward smaller sized CHP systems. The 2016 installations included 30 new systems in multi-family buildings, hospitals, colleges/universities, and installations at several other commercial, institutional, and industrial application types.
Natural gas was the predominant fuel type for new CHP installations, and supplied the fuel for 80% of new systems in 2016. However, 16% of all new CHP capacity in 2016 was fuelled by waste or biomass fuels, which is twice the typical proportion of CHP capacity fuelled by biomass. CHP systems help to avoid 241 million metric tons of CO2 emissions annually in the US.
