Combined Heat and Power

Combined Heat and Power (CHP), sometimes referred to as cogeneration, helps stabilize the utility grid by generating electricity close to the site of use. These systems save energy by using the waste heat from on-site electricity generation to heat the building or to provide hot water. CHP installations help reduce the need for additional power plants and transmission lines. CHP can generate electricity cleanly and efficiently when powered with natural gas or renewable fuels.

Address
11651 Nebel Street, Rockville, MD 20852
Description
The heat and electricity generated by a natural gas microturbine are used on-site with an overall efficiency of 68% compared to 33% for the average large power plant. The continual electrical and hot water needs make this residential facility ideal for a combined heat and power system. This project was partially funded by the Maryland Smart Energy Communities Program.

Microgrids

Microgrids are small scale power grids that can operate independently of the local utility. Microgrids combine a variety of technologies such as solar, combined heat and power, batteries, and advanced controllers to allow self-sufficient operations. Microgrids improve the resiliency of buildings and campuses to utility interruption, help stabilize the overall grid by generating electricity during periods of peak demand, and can reduce greenhouse gas emissions. The County plans to install microgrids at critical public safety facilities.
