By working together, our members share in the benefits from a growing supply of emissions-free renewable energy, including hydropower, wind and solar, and from a highly dependable and cost-effective fleet of coal and natural gas power plants. We own generation facilities, contract for long-term power purchases and buy power from the market to meet our members’ energy and capacity needs. Our members can also self-supply a portion of their needs from local resources.
Helping members use energy wisely is a big part of what cooperatives do. We offer programs that support energy efficiency and promote and share information about new technologies that meet the unique needs of rural consumers and businesses. Our programs span the range of energy use, and our pilot programs test and validate new technologies.
In an increasingly complex and competitive energy market, it’s important for our members that we schedule and dispatch resources and buy and sell power in the most optimized and efficient manner possible. Every minute of every day, we determine the optimal mix of more than 30 generation resources to serve our members, and we look far ahead to ensure our members will have the reliable, low-cost energy they need for the future.
It’s a big job to deliver reliable power to communities across nearly 200,000 square miles of the west, from the eastern plains through the Rocky Mountains and down to the southern deserts. We own or operate more than 5,665 miles of high-voltage lines, supported by our system of substations and telecommunications sites. Our transmission maintenance centers work to keep the lights on.
Research and development
Technology is changing at a rapid pace, and we are part of that advancement through our partnerships with leading organizations like the Electric Power Research Institute and the National Rural Electric Cooperative Association. An important part of our efforts is to directly participate in research projects, which helps solve unique challenges, brings us early information on advanced technologies, accelerates the commercialization of new products and provides information exchanges within our industry.

Our renewables: nearly a third
A growing part of our energy portfolio comes directly from water, sun and wind. In fact, nearly a third of the electricity used by our cooperative consumers comes from renewable resources.
Our member systems are also using local, distributed renewable energy projects in many of their communities. Together, we generate possibilities.
Tri-State’s Environmental Management System (EMS) achieves environmental compliance, enhances strategic planning and promotes environmental stewardship.
The comprehensive EMS guides activities and ensures compliance in a systematic approach that accomplishes environmental goals and keeps facilities running efficiently. Tri-State is among the first cooperatives in the nation to adopt EMS. We continue to make sure we’re meeting or exceeding the highest standards of federal and state clean air and water standards
