Indiana Power Plans Sharpen As Siting Rules Tighten
The clearest hard movement yesterday came out of Indiana, where utility planning for new data center load jumped from abstract demand talk to named contracts and supply plans.
Beyond that, it was more a rules-and-pushback day than a groundbreaking day. That fits the pattern of the past week: as projects get bigger, the friction is showing up earlier in utility planning, rate design, and local rulemaking.
NIPSCO said large-load deals in northwest Indiana are tied to much bigger power commitments than utilities have usually had to spell out publicly. For Amazon's planned Hobart campus, filings described 3,000 megawatts of dedicated supply from two 1,300-megawatt gas plants plus 400 megawatts of battery storage; Google-linked load in Michigan City was paired with battery units and 500 megawatts from a contractor.
NIPSCO also confirmed an agreement to buy energy from the Merom coal plant, underlining how quickly data center demand can pull older fossil generation back into the resource mix when utilities need firm capacity fast.
Vermont lawmakers gave final passage to H.727, a new framework for data centers above 20 megawatts that pairs customer cost protections with minimum contract terms, limits on fossil-fuel backup generation, on-site renewable requirements, and water safeguards.
Seattle moved toward a one-year moratorium and a broader policy review that could include a separate rate class for very large loads. Augusta, Georgia, stopped short of a pause for now, but the moratorium idea is moving into more city agendas.
On the finance side, I Squared agreed to buy 10 Cogent facilities for $225 million and pledged another $1 billion for upgrades and expansion. The deal covers about 53 megawatts across nine U.S. locations, a reminder that existing, already-powered sites in constrained markets may be more valuable than undeveloped land.
Key Points
- Utilities are increasingly being asked to do more than connect load; they are being pushed to assemble dedicated generation, storage, and supply contracts around named data center customers.
- The near-term answer to AI-scale demand still includes a lot of fossil fuel, even where batteries and renewable procurement are also part of the package.
- Regulatory response is becoming more formal. Instead of general backlash, more jurisdictions are discussing moratoriums, special rate classes, contract requirements, and operating conditions.
- Water remains part of the siting equation. California disclosure scrutiny and Vermont's water provisions show that cooling impacts are staying in the approval conversation, not fading behind the power story.
- Capital continues to chase scarcity. Buying existing facilities in supply-constrained metros is emerging as a practical alternative to waiting on greenfield power timelines.
Implications
For builders, power access is turning into a full project-development question involving fuel mix, utility approvals, and who pays for new capacity, not just interconnection timing.
For utilities and regulators, the tradeoff is getting starker: fast data center growth can support new investment, but it also raises direct questions about ratepayer exposure and emissions.
For markets competing for AI infrastructure, clear siting and utility rules may matter almost as much as cheap land.
Watchpoints
Watch
How Indiana regulators and utilities handle the gas plants, battery storage, and cost allocation tied to the Hobart and Michigan City loads.
Watch
Seattle's June 2 committee vote and possible June 9 council vote on a moratorium and related policy work.
Watch
Whether Vermont's new framework and California's water-disclosure push become templates for other states.
Fallout
Yesterday's developments were strongest on three durable pressures: utilities turning hyperscale demand into specific power plans, governments tightening control over approvals, and water moving further into the center of siting debates.
Electricity Demand Pressure
Large AI and cloud campuses are now big enough that utilities often need to line up new capacity, storage, and contract structures before a project can feel real.
Fresh developments
Indiana provided the clearest example. NIPSCO tied Amazon's planned Hobart campus to filings describing two 1,300-megawatt gas plants and 400 megawatts of battery storage, while Google-linked load in Michigan City was paired with battery units and 500 megawatts from a contractor. The same day, I Squared bought 10 Cogent facilities and committed more capital to upgrades, showing how valuable existing powered sites have become in tight markets.
Why we noticed
This is the stage where demand stops being a forecast and starts reshaping utility plans, fuel choices, and investment strategy. It also makes cost allocation and emissions harder to sidestep, because the required infrastructure becomes visible.
Watch for:
- Whether Indiana regulators scrutinize the proposed gas plants and related cost recovery as data-center-driven supply.
- Any disclosure on transmission, substation, or large-load tariff changes tied to the Hobart and Michigan City projects.
- More deals for already-powered assets in constrained metros rather than pure greenfield announcements.
Local Siting Control
Cities and states are increasingly deciding that standard industrial zoning is not enough for very large data centers, especially when projects carry visible power, water, and neighborhood impacts.
Fresh developments
Vermont's legislature gave final passage to a statewide framework for facilities above 20 megawatts, while Seattle moved toward a one-year moratorium and a policy review that could include a special rate class for large loads. Augusta discussed a pause as well, even though officials did not advance it yet.
Why we noticed
These are no longer just protest stories. They are becoming procedural checkpoints that can change timelines, operating requirements, and even whether utilities can treat data centers like ordinary new load.
Watch for:
- Seattle committee and council votes in early June.
- Whether Vermont's bill is signed and how quickly utilities and agencies translate it into operating requirements.
- More cities pairing moratorium talk with special rate classes or siting rules rather than simple yes-or-no bans.
Water Supply Constraints
Cooling water and disclosure are becoming recurring parts of siting fights, even when the day's headlines start with electricity.
Fresh developments
A California report highlighted how difficult it still is to find clear public data on planned water use as facilities spread into stressed parts of the state, and lawmakers are again pursuing disclosure requirements. Vermont also wrote water protections directly into its new large-data-center law.
Why we noticed
Water can turn from a secondary talking point into a real permitting obstacle once projects move into drought-prone or groundwater-stressed areas. The more opaque the planning, the easier it is for local opposition and state oversight to harden.
Watch for:
- Movement on California bills requiring water-use disclosure and stricter review in overdrafted basins.
- Whether developers start volunteering project-level water data earlier in the approval process.
- Cooling and wastewater-reuse commitments in water-stressed markets.
Final Thought
Yesterday did not bring a single decisive turn, but it did make the current hierarchy clearer. First secure power, then secure permission to use it on terms a utility, regulator, and host community will accept.
