NIPSCO’s proposed 22% electric rate increase is big, but it’s not the only one facing Indiana regulators now. Three of the state’s investor-owned utilities are asking for $40-plus monthly rate increases, “the likes of which we’ve never seen,” Citizens Action Coalition Executive Director Kerwin Olson said. For NIPSCO’s typical residential customer, that’s a monthly increase of about $32, according to the utility, although the Citizens Action Coalition says it’s more like $45.
