HB 146 — Affordable Electricity Act of 2026

Deferred
Current Status
Last verified: March 2026

Legislative Status

Deferred until 2027. HB 146 was killed in the House Transportation, Highways & Military Affairs Committee after hearing testimony almost exclusively from utility representatives (Rocky Mountain Power). Utilities argued safety concerns and grid cost-sharing. No active law restricts plug-in solar — the bill simply did not pass.

Sponsored by: Rep. Clark Stith
