27% of the energy Tri-State and its members deliver to co-op consumers comes from renewable energy.

We are the #1 G&T in the nation for solar energy production.                                       

Tri-State was previously named wind cooperative of the year.                                      



Nearly half a million homes are powered by renewable resources in our members' service territories. We have been delivering electricity using hydro power since 1952. Renewables have been in our generation mix from the start.




Our members are leading the way

Tri-State also supports its members’ development of local renewable energy and distributed energy resources, with incentives and technical support for the development of member-owned or sponsored projects. Collectively, these member projects (completed or under development) account for approximately 76 megawatts of renewable energy resources.
