April 9, 2002 – The National Aeronautics and Space Agency (NASA) has installed an enterprise energy management (“EEM”) system to control power usage and reduce costs at its Ames Research Centre facility near San Francisco, California, manufactured by Power Measurement.

Designed by Jacobs/Sverdrup Technology, the Ames Power Monitoring System (APMS) monitors power usage throughout the centre, including the facility’s three large wind tunnels, used regularly for aeronautic research and development testing.

The system uses ION® Enterprise™ software installed on over a dozen PC workstations combined with approximately a hundred ION 7330™ and ION 7700™ meters (at full implementation), to help facility personnel manage
and schedule real-time and future energy usage.

The energy management system helps the centre to avoid incurring costly demand penalties by enabling wind-tunnel operators, test engineers, and power managers to monitor total demand for the centre in real time. Personnel receive the information they need to schedule energy-intensive procedures in advance, and vary loads in real-time to ensure the facility does not exceed the maximum allowable demand level.

Since the deployment of the APMS, Ames Centre has achieved significant energy cost savings by helping facility personnel to maintain integrated demand below monthly allowable levels, manage overall power factor (PF) to avoid low PF penalties, and use historical system data to identify opportunities for additional energy savings.

The system also provides power engineers and electricians with the information they need to perform advanced modifications and day-to-day maintenance of the centre’s electrical distribution system.
