In this report, as an indicative case study of this broader trend, we examine the cost-savings opportunities renewables price declines have made possible for Tri-State Generation & Transmission Association and its member co-ops. Specifically, we consider their opportunity to engage in large-scale procurement of costeffective renewable energy projects, while maintaining system reliability requirements. We analyze two illustrative power supply portfolios based on publicly available data, and find that procurement of new wind and solar projects represents approximately $600 million of cost-savings potential for Tri-State’s members through 2030, versus continued reliance on legacy coal-fired generation. Scaled adoption of renewable energy by Tri-State could also mitigate risks of revenue loss and cost increases associated with reliance on existing assets for electricity supply, reducing the rate increases under a range of risk scenarios by 30% to 60%.
