Southwestern Electric Cooperative provides electric service to nearly 23,000 residential, commercial, agricultural and industrial member accounts in southwestern Illinois, including portions of the St. Louis Metro East.

As a not-for-profit utility company, Southwestern Electric is committed to providing high-quality energy services at the lowest possible prices. We are also guided by the simple belief that a member-owned and member-controlled energy company should always operate in the best interests of local families, neighbors and communities. The cooperative strives to provide affordable and reliable energy, and to return earnings whenever possible, to its members.
