Using CHP to Reduce Energy Use by More than 18 Percent

Today in Washington D.C., EPA recognized three Energy Star Combined Heat and Power (CHP) Awards winners for using CHP to reduce their energy use by more than 18 percent. CHP, also referred to as cogeneration, is an efficient, clean, and reliable approach to generating power and thermal energy from a single fuel source. By installing a CHP system, a facility can increase operational efficiency and decrease energy costs, while reducing air pollution and greenhouse gas emissions.

Awardees included:

Calpine Columbia Energy Center (Gaston, South Carolina) for its combustion turbine-based CHP system that produces up to 500 MW of electricity and one million pounds of steam per hour. The local utility grid receives all of the generated electricity while an adjacent manufacturing plant productively utilizes the steam. This highly efficient CHP system requires 30 percent less fuel than typical alternatives.

University of New Mexico CHP Project (Albuquerque, New Mexico) for its natural gas-fired CHP system at the Ford Utilities Center. Part of a major energy infrastructure upgrade project, the CHP system supplies the campus with roughly one-third of its total electricity demand and produces steam to help meet the space heating, space cooling, and domestic hot water production needs of more than 25,000 students, staff, and faculty. With an operating efficiency of almost 65 percent, the CHP system requires 20 percent less fuel than typical alternatives.

Verizon Garden City Fuel Cell Project (Garden City, New York) for its fuel cell CHP system. Located at a Verizon call routing center, the CHP system is the largest U.S. commercial fuel cell installation of its kind. Hot water that would otherwise be wasted is recovered and used for the space cooling and heating of an office building that serves more than 35,000 telecommunication customers. With an operating efficiency of almost 60 percent, the CHP system requires 25 percent less fuel than typical alternatives.
