Abstract
(HB6135 · 103rd Legislature) Public utilities: rates; large load commercial rates for data centers; establish. Amends 1939 PA 3 (MCL 460.1 - 460.11) by adding sec. 10ii.

Why this matters
Data centers represent a fast-growing source of large, concentrated electricity demand that can shift cost allocation and capacity planning for all Michigan ratepayers. Creating a dedicated large load commercial rate class would give regulators a statutory basis to isolate data center costs and revenue requirements rather than blending them into general commercial rates, with downstream effects on utilities’ load forecasts and industrial siting decisions.
