Google, Apple and Facebook sent a letter to North Carolina legislators urging them not to change the state’s renewable energy laws.  State representatives are considering a bill that green energy advocates say would negatively impact the renewable energy sector.

The tech giants’ letter urges legislators not to adopt House Bill 332. The proposed legislation would make significant changes to the state’s Renewable Energy Portfolio Standard (REPS).

The REPS requires utility companies to buy a certain percentage of their energy from renewable sources, such as solar or wind power. The REPS also requires utilities to increase the percentage of clean energy they buy over time. Allison Eckley of the North Carolina Sustainable Energy Association (NCSEA) says the REPS has been key for the growth of green energy companies in North Carolina, and to keeping rates down for consumers.

“We’ve already seen the downward pressure on electric bills that these policies have had,” Eckley said.

House Bill 332 wouldn’t get rid of the REPS, but it would freeze the REPS requirement at its current 6 percent. Google, Apple and Facebook expressed concern in last week’s letter to legislators that limiting the REPS would hold back the growth of North Carolina’s renewable energy sector. The three companies employ 200 people in North Carolina and have invested $2.7 billion in the state. More than half of their investments are in the renewable energy sector, according to a statement from NCSEA.

“They’ve been following the policy developments here because they consider clean energy as a supplier to that power as a priority. And that’s part of the reason, as they say in the letter, that they selected North Carolina instead of other states in the Southeast that also have cheaper electricity,” Eckley said.

House Bill 332 is co-sponsored by Rep. Mike Hager, a former Duke Energy employee. He and other proponents of House Bill 332 say the REPS unfairly support the renewable energy industry over other sectors. Becki Gray, from the Raleigh-based conservative think-tank, the John Locke Foundation, agrees.

“This mandate, these special favors that are granted to the solar industry at the expense of taxpayers is not good policy. It doesn’t lead to good economic growth,” Gray said.

Gray argues the opposite of Google, Facebook and Apple when it comes to the REPS’ downward pressure on rates.

“The studies that we’ve seen show that that is not true, that the costs increase with the requirement that a certain percentage of your energy has to come from more expensive sources,” she said.

House Bill 332 is being debated in the Senate. For now, the one thing both sides can agree on is the need for more research on the REPS’ economic impact.
