 generation fleet to more cost-effective, lower-emitting generating resources. Our generating fleet transition plans and GHG goal setting processes take into consideration many factors, including resilience, reliability and affordability as well as GHG reduction. Incorporating each of these important elements allows us to follow an achievable and orderly track as we pursue our net zero by 2050 goal.

4 We continue to make progress toward our interim goal of reducing Scope 1 GHG emissions by 50% from 2007 levels by 2030. We have preliminarily achieved GHG reductions of 49% below 2007 levels in 2024.

4 We continue to project our owned and contracted renewables and energy storage resources to reach approximately 21,000 MW by 2030.

We believe our path to net zero will be achieved through:

4 Continued coal fleet transition

4 Thoughtful use of natural gas

4 Further growth in portfolio of zero- carbon resources

4 Negative carbon solutions

4 Enhanced energy efficiency initiatives

4 Continued investment in R&D focused on clean energy technologies

4 From 2007 through the end of 2024, we reduced the number of coal units from 66 to 15 and our nameplate coal capacity from 20,457 MW to 8,523 MW.
