SF 102 Wyoming House · 2026 Regular Session

Wyoming energy transmission study.

Wyoming's SF 102 requires the Wyoming Energy Authority to complete a two-phase study of the state's electricity transmission system. Phase one (due November 2027) analyzes how three load growth scenarios (low, moderate, high) would impact current infrastructure through 2046, identifying potential bottlenecks and solutions. Phase two (due September 2028) examines integrating Wyoming's grid into regional markets and evaluates economic benefits for each scenario. The study will inform future legislative recommendations on transmission needs and upgrades.

MODERATE

The bill was finalized as an enrolled act, changing the title to focus on the 'Wyoming energy authority' and adding a requirement for an advisory working group to include rural co-ops, investor-owned utilities, municipal utilities, the public service commission, and the consumer advocate. The study scope was slightly adjusted to include a qualitative summary of utility participation in regional markets, while the reporting deadlines for the study phases were retained from the original draft.

Scope change

The bill's scope was expanded to explicitly include an advisory working group with specific stakeholder representation and to require a qualitative summary of regional market participation in the study.

REQUIREMENT

Added a requirement to establish an advisory working group that must include representatives from rural electric cooperatives, investor-owned utilities, municipal utilities, the public service commission, and the office of consumer advocate.

Added a requirement for the study to include a qualitative summary and narrative of public utilities' participation in regional transmission organizations and electricity markets.

Modified the study requirements to change the power flow assessment language from 'power flow assessment' to 'assessment' and removed the specific requirement for recommendations for transmission solutions in Phase One.

TECHNICAL

Added standard enrolled act formatting elements, including the Governor's signature block, certification of Senate origin, and specific session identifiers (Enrolled Act No. 50, 68th Legislature, 2026 Budget Session).
