2023 Tri-State Investor Presentation
A DIVERSE & RELIABLE GENERATION PORTFOLIO
How we generate and purchase power is important to our members.
Tri-State is able to meet our members' needs by deploying clean
energy resources via our long-term purchase power contracts, an
efficient fleet of owned generation resources and market purchases.
Our diverse generation portfolio leverages the West's plentiful natural
resources to generate reliable and affordable electricity for our
membership. We manage risks and costs of power generation by
utilizing clean energy resources, including hydropower, wind and
solar. We back that up with our efficient base load-serving coal
generating units, intermediate load-serving natural gas combined-
cycle generating units, and peak load-serving natural gas and oil
combustion turbines.
To manage the costs of energy production, we use coal from
Tri-State-owned mines and contract for other coal supplies through
our cooperative network. In addition, several of our gas plants are
dual fuel and allow for alternative fuel options, protecting us from
market price volatility.
