History of the SEU
Stillwater is the 2nd largest municipally owned electric utility in Oklahoma and the
largest municipal electric generator in the State.
Stillwater has owned its Electric Utility since 1901
and began generation of it’s own electricity in 1903.
Boomer Lake StationBoomer Lake Station was the built in the
1950’s and was renovated in the 1990’s as part of a 20 year life extension project.
Feasibility Analysis
1. Rebuild Boomer Lake Station
2. Build a new State of the Art Generation Facility
3. Get out of the generation business
Was it economically feasible to build generation in the City of Stillwater?
In January of 2013 the study came back that it would be beneficial and economically viable for SEU to own new
generation
