NASA's Lyndon B. Johnson Space Center Starts Construction on Mission-Critical Energy Islanding Project

Tuesday, March 8, 2016


Houston, Texas – Energy Systems Group (ESG), a leading energy services provider and wholly owned subsidiary of Vectren Corporation (NYSE: VVC), began construction of a combined heat and power (CHP) plant at the Lyndon B. Johnson Space Center (JSC). The CHP plant is included in the scope of an energy savings performance contract (ESPC) awarded to ESG in August 2015 by the National Aeronautics and Space Administration (NASA). Established in 1961 as the Mission Control Center for NASA’s U.S. Human Space Flight Program, JSC is one of NASA’s largest research and development centers, occupying 1,620 acres southeast of downtown Houston. JSC serves as NASA’s lead for the International Space Station (ISS) and is home to the Orion Spacecraft, the NASA Astronaut Corps, and other advanced human exploration projects.


The CHP facility will operate in parallel with the utility, meeting nearly 70 percent of JSC’s electric requirements, all of JSC’s steam requirements, and roughly half of JSC’s chilled water requirements. Capable of operating as an islanded microgrid, the CHP plant will provide energy for critical mission operations such as ISS Mission Control and the Orion program in the event of a utility power disruption.  This represents a new way of thinking about utilities at JSC. As the JSC center changes, the new CHP system, the first ever for NASA, will allow JSC to adapt to new programs, new requirements, and new ways of being flexible.


The ESPC project’s two energy conservation measures, a CHP plant and chilled water plant improvements, will save approximately $141 million over a 22-year operating term. The CHP plant will produce 11.9 megawatts of electricity via two 5.7 megawatt combustion turbines and one 500 kilowatt steam turbine. Using waste heat from the combustion turbines, two heat recovery steam generators will produce 50,000 pounds per hour of high pressure steam. The steam will be simultaneously used for heating and to generate chilled water via existing steam turbine-driven chillers. Conventional utility power generation systems typically operate at 35 to 45 percent efficiency. Using the waste heat generated by the NASA JSC CHP plant for both cooling and heating allows for overall tri-generation thermal efficiencies in excess of 85 percent. Recommissioning of the chilled water system will result in still more efficiencies. ESG will provide operations and maintenance, repair and replacement and savings guarantees for the term of the contract.


As part of an interagency collaboration, the U.S. Department of Energy awarded JSC a $1 million grant to provide direct funding for the project and assisted the center in the preparation and evaluation of the contract and specifications for the CHP.


“ESG is proud to support NASA in the development and construction of this mission-critical energy islanding project,” said Greg Collins, ESG President. “This highly efficient CHP plant will reduce greenhouse gases by approximately 20,000 metric tons of carbon dioxide annually,” added Collins. “That is equivalent to keeping about 4,100 passenger vehicles off the road each year.”


The other NASA centers and Headquarters are very interested in this project and how it can help not only JSC meet its energy goals, but all of NASA. The ESPC project is expected to reduce JSC energy intensity by more than half as compared to 2014 levels and will help JSC meet site energy intensity reduction goals through 2025. The project will reduce NASA agency-wide energy intensity by roughly 10 percent as compared to 2014 levels. More than 50 local jobs will be created to support construction of the CHP plant and to implement additional efficiency measures.
