Maine regulator seeks Iberdrola records amid CMP rate push
On Wednesday, Maine’s Public Utilities Commission asked the utility’s Iberdrola parent for internal documents that show how it calculates the earnings needed to cover costs and satisfy investors. The case accompanies Central Maine Power’s request to raise residential distribution rates by about $18 per month, shifting its return on equity from 9.35% to 9.8%, after a prior longer-term proposal was rejected.
