Today, New Hampshire currently has 17 CHP sites. Of the 17, 2 are located in hospitals or healthcare centers, 3 in colleges or universities, and 2 are in textile plants, among other uses. Altogether, these systems boast a capacity of 46.768MW. This information along with further details can be found at the U.S. DOE Combined Heat and Power Installation Database.
In a study conducted by the Department of Energy in March 2016, it was apparent New Hampshire's CHP capacity still has room to grow. New Hampshire has 447 MW of overall CHP capacity identified at 1,363 sites.
Policy & Incentives
New Hampshire has a number of programs and incentives designed to promote and support new and existing CHP projects. CHP qualifies for the state's Renewable Portfolio Standard if fueled with biomass. In addition, renewably fueled CHP can receive "useful thermal energy" output credit for its electricity output. For more information, visit http://programs.dsireusa.org/system/program/detail/2523. Commercial CHP projects may be eligible for financing assistance through the Clean Energy Fund. Finally, CHP may also qualify for net metering, but this is capped at 4 MW of aggregate capacity statewide.
