2023 Tri-State Investor Presentation
RESILIENCE
RESPONSIBLE ENERGY PLAN
We eliminated CO2 emissions from Tri-State-owned Escalante Generating Station in New Mexico in 2020. In
Colorado, by 2030, we are targeting a 100% reduction in CO2 emissions from Tri-State-owned coal generation, a
90% reduction in CO2 emissions across generation we own or operate, and an 80% reduction in CO2 emissions
associated with state wholesale electricity sales. At the same time, we will have brought more than 1,000 MW of
new wind and solar resources online between 2021 and 2025, with plans to add additional resources through
2030 pending modeling of resource acquisition needs and approvals from the Colorado PUC. Our current goal is
to supply our members with 70% clean energy system-wide by 2030.

We're providing retraining and transition support for employees affected by these changes. We are also working
with impacted communities, as well as state and federal government entities to find meaningful economic
development opportunities to support a just transition.
The Colorado PUC approved Tri-State's Phase I 2020 Electric Resource Plan and settlement agreement. Under
the settlement, Tri-State agreed to reduce greenhouse gas emissions related to its wholesale electricity sales in
Colorado (relative to 2005 baseline) as follows: 26% in 2025, 36% in 2026, 46% in 2027, and 80% in 2030.
Tri-State's Phase II 2020 Electric Resource Plan preferred bid portfolio, with a new wind project coming online
in 2026 is awaiting Colorado PUC approval, expected in May 2023.
