Michigan documented that 20% of low-income heat pump participants saw bill increases — and no state adopted safeguards
Five states are promoting heat pump adoption for LMI households. None has enacted binding consumer protections against the documented risk that electrification increases energy burden. The populations least able to absorb financial risk bear the most technology risk.
20%
Of income-qualified multifamily participants saw bill increases averaging 24%
Consumers Energy cold-climate heat pump pilot: 663 installations, 2020-2021. Causes included continued baseboard heating use, non-optimal HP operation, added cooling load, and behavioral takeback. The evaluation warned: "Need for additional analysis and efforts to avoid negative outcomes for these customers least able to afford them."

Michigan — the evidence
DTE single-family HP pilot: only 7% savings vs. expectations
Baseboard heaters were "not disabled at electric panel for most homes" and customers were "not clear that continued usage would impact energy savings." The breakeven analysis concluded gas customers "would likely not see lifetime economic savings from heating electrification."

Massachusetts — the disclaimer
Mass Save explicitly disclaims performance warranties
"Sponsors do not endorse or warrant the performance of installed or serviced equipment and do not make any representations or warranties regarding the services provided by these contractors." LI customers bear all technology risk.

Vermont — the acknowledgment
PUC and EAG both acknowledge electrification may increase LI burden
Act 142: "not all customers will save money through electrification." EAG: the CHS "is likely to increase fuel costs, and therefore increase the energy burdens of low and moderate income Vermonters, at least in the short term."
Act 142 Final Report, VT PUC, Dec 2025, p. 2 fn. 2. CHS EAG Final Report, Jan 7, 2025, Exec Summary p. 1.
Wisconsin — the finding buried in a report
PSC's own market assessment found HPs "will typically increase heating costs" for gas homes
The 2023 ASHP Market Report identified ~300,000 propane/resistance homes that could save, but documented that gas-heated homes face a cost penalty. The Quad IV Order restricts Focus on Energy from claiming fuel-switching savings through 2026.
PSC ASHP Market Report, July 14, 2023, ERF docid 472912. Quad IV Order, Nov 2022, Docket 5-FE-104.
The five-state evidence reveals a regulatory pattern: states acknowledge the risk of bill increases from electrification in study reports, pilot evaluations, and advisory group findings — then proceed with program expansion without adopting binding consumer protections. Michigan has the most detailed evidence of consumer harm. Massachusetts has the most explicit warranty disclaimer. Vermont has the most candid official acknowledgment. No state has acted on any of it.
The consumer protection void exists because no regulatory framework anticipated fuel-switching as a program outcome. Weatherization consumer protections (contractor standards, work specifications, quality control) exist in PA and are developing elsewhere. Electrification consumer protections don't exist because the programs are new — but the risks are already documented.
