Indiana Commercial Electricity: Limited retail choice with rates set by the IURC. Average commercial rate: 10.0-12.5¢/kWh (2026). Indiana spans two ISOs—NIPSCO in MISO and Duke/AES in PJM—creating distinct pricing dynamics. The state's heavy manufacturing base makes industrial tariff optimization critical.
A manufacturing powerhouse spanning two ISO markets. NIPSCO (MISO) in the north and Duke/AES (PJM) in the central/south.
NIPSCO is undergoing a significant generation portfolio transformation, retiring coal plants and replacing them with wind, solar, and natural gas. The transition costs are being recovered through base rate increases approved by the IURC.
View NIPSCO Rate Analysis →Northern Indiana (Gary, South Bend, Fort Wayne) is served by NIPSCO within the MISO market. MISO capacity prices have historically been lower than PJM, but the Zone 6 shortage is narrowing this gap significantly.
Central and Southern Indiana (Indianapolis, Bloomington, Evansville) falls within PJM Interconnection. These territories are subject to PJM capacity auction results, which cleared at record highs for the 2026/2027 delivery year.

Indiana is a top-10 US manufacturing state. Automotive, steel, pharmaceuticals, and logistics drive massive industrial loads with unique rate structures and interruptible tariffs.
Indiana historically relied on coal for 60%+ of generation. The aggressive retirement schedule (NIPSCO, Duke) is creating rate volatility as replacement resources come online.
Northern Indiana is part of the MISO wind corridor. NIPSCO is replacing coal with utility-scale wind and solar, creating long-term rate stability at the cost of near-term increases.
Whether you're in NIPSCO's MISO territory or Duke's PJM zone, our team can identify tariff optimization and demand response opportunities.
