Efficiently Generating Electricity and Thermal Energy

Cogeneration is a cost-efficient means of generating both electricity and thermal energy from the same fuel source. Also known as combined heat and power (CHP), it is a clean, reliable source of power for commercial, industrial, and municipal customers.

There is a growing demand for this type of power. Both state and federal incentives and requirements are growing for Green power. Large fossil power plants are going offline, while electricity demands are growing in the U.S. There is a growing trend for smart grid and micro grid technology. At Peterson, the type of products we offer makes us a strong player in these emerging markets.

Peterson has a range of solutions and processes to provide and support your business in order to make sure that your energy is used efficiently. Our energy solutions not only help reduce energy use, they also reduce energy costs.
