MARION, S.D.(WNAX)- The Federal Energy Regulatory Commission has been warning of possible power shortages, especially in the Midwest this summer.

A combination of coal plant retirements, increasing demand and shortage of power line capacity could lead to the short fall.

Brad Schardin, manager of Southeastern Electric based in Marion, says they have a variety of electricity sources.

Schardin says there have been power issues with some regional electric grids.

Schardin says Basin Electric and the cooperatives have been working on long term power supply plans.

Southeastern Electric is holding their annual member meeting this Thursday in Lennox.
