Duke Energy Carolinas filed requests Thursday that would increase typical residential bills $2.86 a month to pay for energy efficiency programs.
The filing with the N.C. Utilities Commission is separate from the 9.7 percent rate hike Duke Carolinas requested last month. That request, if granted, would increase typical residential rates by about $14 a month.
The energy-efficiency increase is linked to Dukes Save-a-Watt efficiency pilot program, which will end in December, and proposed new efficiency programs that would go into effect in January.
A separate part of customer bills, for fuel costs, will remain unchanged
