Cogeneration

Energy-efficiency on a large scale.

Managing the energy needs of a big facility can be a daunting prospect. National Grid routinely works with commercial, industrial, and municipal customers to reduce energy costs on a large scale. One way is through cogeneration, or combined heat and power (CHP), a highly efficient form of energy conversion that generates heat and electricity simultaneously, then captures and reuses heat that would otherwise be wasted. CHP is 40% more efficient than heat and power provided separately.

If you have a large-scale facility or a multi-building complex with consistent power and thermal loads, National Grid can connect you with CHP vendors who provide incentives to qualifying customers.
