About Us

Reliability through Relationships

The SPP Mission: Helping our members work together to keep the lights on, today and in the future.

SPP is about more than power. We’re about the power of relationships.

SPP was founded in 1941 when eleven regional power companies pooled their resources to keep Arkansas’ Jones Mill powered around the clock in support of critical, national defense needs. (Read more about our history.)

Now, more than 75 years later, we’re proud the SPP of today still reflects those early principles of collaboration in the interest of providing a critical service for the good of our region.

What We Do, and for Whom

Today, SPP oversees the bulk electric grid and wholesale power market in the central United States on behalf of a diverse group of utilities and transmission companies in 14 states.

We ensure the reliable supply of power, adequate transmission infrastructure, and competitive wholesale electricity prices for a 546,000-square-mile region including more than 60,000 miles of high-voltage transmission lines.

Our staff of about 600 professionals works proudly and diligently to ensure that more than 18 million people in our footprint have electricity when they need it.
