Briefings
Duke Energy announced a clean transition tariff framework in May 2024 with major tech and steel companies, but it has not been formally adopted. The utility later filed a tariff proposal in July 2024 that excludes the clean transition tariff component, citing insufficient detail and preferring to explore existing green tariff programs first. While the original 2024 memorandum of understanding is effectively dead, the utility remains engaged with Google to consider a CTT in a separate merger settlement. The North Carolina Utilities Commission has indicated that rate cases may handle a CTT, though no formal proposal has been filed yet.
Key points
- Duke Energy announced a clean transition tariff framework in May 2024 with Amazon, Google, Microsoft, and Nucor, but the framework has not been formally adopted.
- By July 2024, Duke Energy filed a final large load tariff proposal that explicitly excludes the clean transition tariff component, stating no party has presented sufficient detail for such a program.
Context and limitations
Coverage is limited to Duke Energy's actions and the North Carolina Utilities Commission's statements regarding the clean transition tariff. The evidence does not include responses from Google, Nevada Energy, or other stakeholders. The timeline ends at the July 2024 filing, with no information on subsequent developments.
