Data in this visualization comes from the 2024 Annual Utility Decarbonization Report
Which U.S. Utilities Are Investing in Clean Energy the Most?
Decarbonizing the power sector will require significant investments in clean energy as utilities replace existing fossil fuel infrastructure.
In this graphic, we show which U.S investor-owned utilities (IOUs) have allocated the most capital expenditure (CAPEX) toward clean energy.
The data comes from the latest edition of the Annual Utility Decarbonization Index, created in partnership with the National Public Utilities Council, which quantifies and compares the status of decarbonization among the largest U.S. IOUs.
The Carbon-Free Investment Ranking
The Utility Decarbonization Index ranks companies on six metrics based on the latest available data, specifically those that pertain to their fuel mix, carbon emissions, and decarbonization goals.
The sixth and final metric measures the share of each utility’s planned CAPEX for carbon-free electricity generation, such as nuclear power and renewables.
Here are the top scorers out of the 47 IOUs included in the report.
| Rank of Company | Company | Share of Planned Generation CAPEXAllocated To Nuclear & Renewables |
|---|---|---|
| #1 | NextEra Energy | 100% |
| #2 | Public Service Enterprise Group | 100% |
| #3 | Avangrid | 100% |
| #4 | Pacific Gas and Electric* | 96% |
| #5 | Alliant Energy | 94% |
| #6 | National Grid | 93% |
| #7 | AES Corporation | 92% |
| #8 | Constellation Energy | 90% |
| #9 | WEC Energy | 90% |
| #10 | Emera | 86% |
| #11 | Dominion Energy* | 84% |
| #12 | American Electric Power | 83% |
| #13 | TransAlta | 81% |
| #14 | MGE Energy | 78% |
| #15 | Duke Energy | 68% |
| #16 | Evergy | 68% |
| #17 | DTE Energy Company | 67% |
| #18 | Fortis Inc. | 67% |
| #19 | Consumers Energy | 66% |
| #20 | Southern Company | 63% |

Avangrid climbed to first place in 2022, tying with NextEra and PSEG, who both maintained their 100% carbon-free investment plans from 2021. This marks an improvement from Avangrid’s 98% the year prior.
Meanwhile, National Grid pulled off the most significant percentage increase, from 3% to 93% from 2021 to 2022.
Overall, carbon-free investment is up 3 percentage points year-over-year from 63% to 66% for the top 47 IOUs.
Which Utilities Are Included in the Decarbonization Index?
The IOUs ranked in this year’s Utility Decarbonization Index are the 47 largest in the U.S. by their 2022 net owned and purchased electricity generations.
U.S. IOUs that had fewer than 2 million megawatt-hours (MWh) of owned generation were excluded from the report.
The 47 IOUs featured in the Index accounted for over two-thirds of the nation’s electricity generation in 2022. As a result, these utilities’ decarbonization efforts will significantly impact the 33% of U.S. emissions that come from the power sector.
