Did You Know?

  • Stillwater Electric Utility was honored recently in 2004 and again in 2006 as the most reliable electric service provider among Oklahoma municipal utilities of similar size. Stillwater’s average system availability index (ASAI) has been 99.98% or better during each of the last 4 years.
  • You can report a street light outage using our Assistance Request Systemor by calling 742-8230.
  • Compact Fluorescent Lamps (CFLs) - An energy saving alternative to standard (incandescent) light bulbs, CFLs use less wattage to give you the same lighting power as a larger wattage standard bulb.
  • Lightning kills nearly one hundred people every year in the United States and injures hundreds of others. When you first notice an upcoming storm, remember that lightning usually precedes rain. Go to the nearest building or car and stay inside until the storm has passed. Do not wait until the storm begins to take cover. Protect yourself and your family by moving to a safe place. Stay in the safe place until signs of lightning and thunder have been past for thirty minutes.
  • light poleThe light poles along Boomer Lake walking trail are now numbered to assist pedestrians when reporting non-working lights. Call 742-8230 or use the online Assistance Request System and note the pole number of the non-working trail light.
  • Stillwater’s community-owned utility is no longer known as ‘Stillwater Power’. We are simply the electric utility department of the City of Stillwater a.k.a. Stillwater Electric Utility. Our name and logo may have changed but we are the same group of dedicated employees providing the same great service our customers have come to expect.

Boomer Lake Station

1956 - Original power plant commissioned
1959 - Expansion completed
1994 - Plant renovation completed

This facility is primarily used as a summer time "peaking plant" and is put on-line when power prices rise and it becomes cheaper for us to generate electricity rather than purchase it from an outside source. Electric utilities that do not have generation capability do not have the amount of control over their customer's electric rates as those who do. The plant also serves as a year-round standby source of power for the city in case of emergency. For instance, the plant was in operation during the Y2K event and was prepared to keep the City of Stillwater from total darkness if the country's power grid had failed.

The Boomer Lake Station saves Stillwater Electric Utility customers approximately 1.7 to 2.0 million dollars per year.
