PIERRE, S.D.(WNAX)- Managers of rural electric cooperatives have been meeting in Pierre this week.

South Dakota Rural Electric Association general manager Steve Barnett says there are some common problems.

Barnett says most cooperatives are seeing rising demand for electricity and assuring service is critical.

Barnett says moving to carbon free or “green” power sources will take some time.

The association has twenty-eight member electric cooperatives.
