Understanding Indiana's Dual-ISO Structure

NIPSCO (MISO Zone 6)

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.

Duke / AES (PJM)

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 Market Guide

🏭

Manufacturing Hub

Indiana is a top-10 US manufacturing state. Automotive, steel, pharmaceuticals, and logistics drive massive industrial loads with unique rate structures and interruptible tariffs.

Coal Transition

Indiana historically relied on coal for 60%+ of generation. The aggressive retirement schedule (NIPSCO, Duke) is creating rate volatility as replacement resources come online.

Wind Corridor

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.
