Pipeline: active generation and storage requests in the ISO queue, or EIA planned plants where larger (outside the ISOs). Top kV: highest substation voltage. Power price: the state's industrial average. DCs: GPU colocation, mining sites and AI campuses.
What the data shows
The strongest Indiana counties for a large AI load are Sullivan County (76), St. Joseph County (70) and Vermillion County (69) on the site score. Indiana sits in MISO and PJM; its ISO queues hold 60 GW of active generation and storage requests, 2.4 GW of them with a signed interconnection agreement, and it has 89 substations at 345 kV and up.
Industrial power averaged 9.2¢/kWh (EIA, July 2026 YTD), against 8.8¢/kWh a year earlier, the 27th lowest of the 50 states and DC. Indiana has a data center sales and use tax exemption in force. We track 3 AI campuses and 11 GPU-ready colocation facilities here.

Data center tax exemption in Indiana
Indiana data center sales tax exemption (IC 6-2.5-15)
Exempts qualified data center equipment and energy purchased by an IEDC-approved user at a qualified data center for up to 25 years (up to 50 years for investments over $750 million); minimum qualified investment within five years of the award certificate is tiered by county population: $25 million (50,000 or fewer residents), $100 million (50,001-100,000) or $150 million (over 100,000); no statutory jobs minimum found.
Recent change: 2026 HEA 1210 requires data centers seeking award certificates to first enter an agreement with the local unit to make a payment reported as up to 1% of their tax savings (reports differ on whether the base is electricity or total savings); a proposal to end the electricity exemption was dropped.
