Wyoming electricity market
Regulated state served by Rocky Mountain Power, Black Hills Energy, and a network of cooperatives. Generation mix is heavily coal and wind; the state hosts some of the strongest wind resources in the US.
Where Wyoming residents save
No retail competition. Low rates and a small population mean residential efficiency is incremental rather than transformative; weatherization through the Wyoming Department of Family Services Weatherization Assistance Program serves low-income households.
