State-owned utility Santee Cooper will shut down four coal-fired units at two of its power generating stations by December 31.
The utility’s board had voted in October to shutter the four units, but Santee Cooper did not give specific dates until Monday. The affected units are at the Grainger Generating Station in Conway and two of the four units at Jefferies Generating Station in Moncks Corner.
The other two Jefferies units are little-used and will eventually be shut down, but no date has yet been announced for those. In a statement, Santee Cooper said the October decision was in response to its changing needs and expensive new environmental regulations that would require significant upgrades at those stations. The two are Santee Cooper’s oldest generating stations.
Santee Cooper says it is relocating affected Jefferies employees to other positions in the utility, so no layoffs are expected. Grainger has been idle since the spring and most of its employees have already been relocated, the statement said.
