Because, prior to 2008 when the renewable energy portfolio standards (REPS) mandate took effect, North Carolina’s electricity rates were decidedly lower than the national and regional averages. Since then, N.C.’s rates have been fast converging on those averages — still lower, but growing at a faster clip than both.
And it’s misleading to hide behind that dwindling advantage to prop up a state law, REPS, that is eroding it by driving rate hikes.
Furthermore, those rate hikes have so far occurred under the lowest threshold of the REPS mandate. As Becki Gray helpfully points out in Carolina Journal today, starting this year the REPS mandate doubles from three percent to six percent. By 2021, it’ll have more than quadrupled.
