Ground zero for America's AI infrastructure debate
Michigan has emerged as a major battleground for data center development, with 11+ large-scale projects proposed since 2024. The state's combination of available land, grid infrastructure, and new tax incentives has attracted billions in proposed investment—and significant community opposition.

To understand data center debates, you need to understand how electricity gets to your home. The U.S. power grid operates in layers, from federal oversight down to your local utility. Here's how it works in Michigan:
Federal Energy Regulatory Commission
Oversees interstate transmission of electricity, natural gas, and oil. Sets wholesale electricity market rules. Approves transmission rates and major infrastructure projects that cross state lines.
Midcontinent Independent System Operator
Operates the regional grid across 15 states including most of Michigan. Manages wholesale electricity markets, balances supply and demand in real-time, and coordinates the interconnection queue for new generation and large loads like data centers.
Note: Southwest Michigan (St. Joseph, Cass, and Berrien counties served by Indiana Michigan Power) operates within PJM Interconnection, not MISO.
Michigan Public Service Commission
Regulates Michigan's investor-owned utilities, sets retail electricity rates, approves utility contracts, and protects consumers. For data centers, the MPSC has become the key decision-maker on major power supply agreements.
IOUs, Municipals, and Cooperatives
The companies that actually deliver electricity to your home or business. Michigan has investor-owned utilities (like DTE and Consumers Energy), municipal utilities (owned by cities), and rural electric cooperatives. Each type operates under different regulatory frameworks.
When a data center proposes to use 500 MW of power (enough for 400,000 homes), it must navigate all these levels. The regional grid operator (MISO) must confirm there's enough capacity. The state regulator (MPSC) must approve contracts that protect other ratepayers. And the utility must actually build or procure the generation.
Regional grid operators don't work in isolation. MISO connects to PJM (to the east), SPP (to the southwest), and other regions through transmission "seams." The Eastern Interconnection links grids from the Rockies to the Atlantic coast—only Texas (ERCOT) operates largely independently.
This means a heat wave in the Southeast, a coal plant retirement in Indiana, or a new data center cluster in Ohio can all affect electricity prices, reliability, and available capacity in Michigan. When grid planners assess whether Michigan can support new data center load, they must consider demand growth across the entire interconnected system.
MISO coordinates the reliable delivery of electricity across a region spanning from Michigan to Montana, manages wholesale electricity markets, and oversees the interconnection queue for new generation and large loads.
Southwest Michigan (St. Joseph, Cass, and Berrien counties) is served by Indiana Michigan Power, which operates in the PJM Interconnection rather than MISO.
State agencies play a critical role in data center development. The MPSC regulates utilities and approves contracts, while other agencies handle environmental permits, economic incentives, and more.
The MPSC regulates Michigan's investor-owned electric and natural gas utilities, setting rates and approving service contracts. For data centers, the MPSC has become the key decision-maker on utility contracts and ratepayer protections.

Each type operates under different regulations and governance structures.

Michigan's electricity generation remains heavily dependent on fossil fuels, though the state has set ambitious clean energy targets. The gap between current generation and future targets is a key tension point for data center development.

Based on Public Acts 229, 231, 233, 234, 235 of 2023
Michigan's 2023 clean energy laws include an "offramp" provision allowing utilities to continue fossil fuel generation if renewable sources cannot handle grid load. Critics argue that adding 7+ GW of data center demand could trigger this offramp, effectively derailing the state's climate goals. The MPSC has stated clean energy compliance will be addressed in separate proceedings.
Michigan has enacted significant legislation affecting data center development, from tax incentives to clean energy requirements. Understanding these policies is essential for following the debate.
Senate Bill 237 / House Bill 4906 | Signed 2024-12-30
Senate Bill 237 (Public Act 181 of 2024), signed December 30, 2024, exempts qualifying data centers from sales and use tax on equipment purchases through December 31, 2050 (extended to 2065 for brownfield sites). A companion bill, House Bill 4906 (Public Act 207 of 2024), amended the General Sales Tax Act.
SB 237's passage and implications are examined in detail in Chapter 9: The Incentives.
Public Act 235 of 2023, Public Act 229 of 2023, Public Act 231 of 2023, Public Act 233 of 2023, Public Act 234 of 2023 | Signed 2023-11
Public Act 235 of 2023 (part of the Clean Energy Future package) and related acts 229, 231, 233, and 234, signed by Governor Whitmer in November 2023.
Critics argue that adding 7+ GW of data center demand could trigger the offramp provision, allowing utilities to continue fossil fuel generation and effectively derailing Michigan's climate goals. The clean energy requirements in SB 237's tax exemption may be met through REC purchases rather than physical renewable generation.
First-in-state data center tariff establishing rules for customers with 100+ MW minimum service threshold. Includes 15-year minimum contract term, ratepayer protection provisions, and prohibitions on cost-shifting.
MPSC conditionally approved 19-year, 1.4 GW power supply agreement for Saline Township (Oracle/OpenAI Stargate) with mandatory ratepayer protections. AG Dana Nessel filed petition for rehearing in January 2026.
Three bills introduced by Democratic senators to regulate data center environmental impacts.
Bipartisan bill introduced by Rep. Dylan Wegela (D) and Rep. Jim DeSana (R) to repeal data center tax incentives enacted in late 2024.
Michigan has 8 documented data center projects in various stages of development. Here are the major active projects:
Saline Township • Washtenaw County
Part of OpenAI's Stargate initiative. 575-acre campus with 2.2M sq ft across five buildings. Called "the largest economic project in Michigan history" by Governor Whitmer. MPSC approved DTE power contracts in December 2025 with ratepayer protections.
Howell Township • Livingston County
Hyperscale campus backed by Meta Platforms. Planning Commission voted unanimously to recommend denial after 7-hour meeting with hundreds of public comments. Township adopted 6-month moratorium in November 2025.
Gaines Township • Kent County
Microsoft purchased 316 acres from Steelcase Inc., less than 5 miles from Switch's data center campus. No site plan submitted yet; project scope and power requirements unknown.
Gaines Township • Kent County
Largest data center campus in eastern U.S. Located at former Steelcase pyramid campus. Over 1M sq ft built out with continuous expansion planned for 10+ years. Part of $5B financing plan.
Ypsilanti Township • Washtenaw County
National security and AI research facility. Received $100M grant from MEDC. Faces significant local opposition over environmental, health, and safety concerns.
Augusta Township • Washtenaw County
