Our Electric Generation Portfolio
Our Electric Generation Portfolio
In 2024, 58% of our electric generation was from carbon-free resources, compared to 40% of megawatt hours generated by the U.S. electric power industry.
Based on MWhs supplied from owned and long-term contracted resources.
Contracted energy from Colstrip Energy Limited Partners (CELP), Yellowstone Energy Limited Partners (YELP) as well as a majority of the contracted wind, hydro and solar are federally mandated Qualifying Facilities, as defined under the Public Utility Regulatory Policies Act of 1978 (PURPA).
NorthWestern does not own all the renewable energy certificates (RECs) generated by contracted resources and periodically sells its own RECs with proceeds benefiting retail customers. Accordingly, we cannot represent that 100% of carbon-free energy in the portfolio was delivered to our customers.
