She noted that while the report predicts electricity rates will increase by 32 percent over the next 10 years, the IURC must review utilities' request for rate increases on a case-by-case basis before that panel decides whether or not to approve rate hikes.
"While this document does give us projections, no costs are passed along to customers until a case actually comes to the commission for review and is approved," McGrath said.
Kerwin Olson, executive director of Citizens Action Coalition of Indiana, said he's pleased the new report acknowledges the role energy efficiency plays in reducing demand for electricity. But he said there's even greater potential for more investment both in energy-efficiency equipment and renewable energy sources such as solar power that could ratchet demand further down.
"I don't necessarily agree that electricity rates have to increase in such dramatic fashion, considering the advances in technologies and the potential that still exists for efficiencies and renewables," he said.
