Keeping Winchester Powered Up

Winchester holds a special place in electrical history. It was the first city south of the Potomac River to use electric lights.

SESCOS is another proud part of Winchester’s electrical history. We’ve been here in your community for more than 60 years, delivering the power you need to keep your homes warm and bright, your businesses humming and your streets safe.

What’s Old Is New Again

Most of Winchester’s early businesses were family-run operations. The same is true for early suppliers of electricity. In the early days of electricity, we didn’t know as much about safety as we do know, and being an electrician was a job that required nerves of steel.

In those days, businesses were familiar parts of the community. Everyone knew each other’s name, family and personal history.

That part of our history is the same. We are a family company that was founded in 1963 by Jack Lee when Winchester had a much smaller population than its current population of 27,000. We now employ more than over 200 talented, licensed technicians that are part of our family, too.

One thing has never changed, and that’s our old-fashioned belief that service is the heart of what we do. We consider our longstanding customers in the Winchester area part of our family as well.
