WHEELER ARMY AIRFIELD, Hawai’i — Amidst a critical need for stable electricity supply on Oahu, the U.S. Army Garrison Hawaii’s Schofield Generating Station (SGS) has risen as a key player in supporting Hawaiian Electric Company's (HECO) infrastructure. Operating five out of its six generating units on January 8, for the duration of the day. The SGS has been providing a substantial 40 megawatts (MW) of power to the island's grid, for over 8 hours with the sixth unit currently undergoing scheduled maintenance.
The SGS, a pivotal asset in the island's power network, extends beyond just meeting immediate power needs. It plays a crucial role in assisting recovery from island-wide blackouts by kick-starting other power plants. Moreover, in the event of an extended island-wide power outage, it is equipped to provide Wheeler Army Airfield (WAAF), Schofield Barracks (SB), and Field Station Kunia with dedicated power for seven days using onsite fuel, and up to 30 days with on-island fuel.
This facility, developed through a collaborative effort between the Army Office of Energy Initiatives (OEI), U.S. Army Garrison Hawai’i and HECO, is not just a testament to military and civilian cooperation but also a key player in enhancing renewable energy usage. The SGS allows for a greater integration of un-firm renewable resources into the grid, maintaining power quality even when solar and wind sources fluctuate, as evidenced by today's extreme conditions.
