Site Description
NASA’s Lyndon B. Johnson Space Center (JSC) has served as a hub of human spaceflight activity for more than sixty years. JSC is home to the nation’s astronaut corps, the International Space Station mission operations, the Orion Program and a host of future space developments. Approximately 7,000 employees occupy the facility, nestled on almost 1,700 acres near Houston.
Funding for The Johnson Space Center (JSC) combined heat and power (CHP) plant was provided through the DOE’s Energy Savings Performance Contracting (ESPC) partnership with Energy Systems Group, an energy service provider. This is a budget-neutral approach to make building improvements that reduce energy and water usage while increasing operational efficiency. The bulk of the project costs, including installation, operation and maintenance, were borrowed through the energy services company and paid for with savings. In this project, utility budget savings are used to fund the ESPC over a 22 year period. Since O&M for new equipment is included, there will be no increase to the current Facilities contract. The ESPC also provides that all ESCO installed equipment have at least 10 years of remaining operational life at the end of the contract term of twenty-two years.
