Michigan applies rigorous subsidy analysis to data centers — but not to residential electrification
The MPSC requires data center customers to prove they pay all costs of service with no cross-subsidization. No equivalent analysis exists for the EWR and MEAP surcharges that fund residential efficiency and electrification measures.
Data center / large load protections
Exhaustive scrutiny applied
✓
15-year minimum contract term
✓
80% minimum billing demand regardless of use
✓
5-year ramp-up to full service
✓
Auto 5-yr extensions; 4-yr termination notice
✓
Exit fee for early termination
✓
Collateral = 50% of exit fee
✓
Per-customer filing proving no cross-subsidy
✓
DTE: 1,383 MW storage funded entirely by customer
vs.
Residential electrification surcharges
Minimal analysis documented
✗
No cost-of-service study for EWR surcharge allocation across rate classes
✗
No analysis of whether non-participants subsidize electrification participants
✗
No proof required that electrification measures don't shift costs to non-adopters
✗
No separate rate class analysis for HP adopter vs. non-adopter households
✗
MEAP surcharge applies to all customers regardless of benefit received
✓
Overall portfolio must pass cost-effectiveness test (UCT ≥ 1.0)
✓
Commission frames system-wide benefit as offsetting non-participant rate impact
~$5.80/mo
Residential surcharges for EWR + MEAP combined: ~$2.00 electric EWR + ~$2.55 gas EWR + $1.25 MEAP. Small per household — but the subsidy flows are unanalyzed.

Cost-allocation studies in this corpus examining whether non-adopters cross-subsidize heat pump or electrification participants through EWR surcharges.
"No other residential, commercial, or industrial customer may subsidize the costs of a new large load customer."
— Commissioner Peretick on Case No. U-21859 (Consumers Energy GPD rate for data centers). The Commission applies this principle rigorously to industrial loads but has not applied the same framework to residential electrification surcharges.
