Press Webinar Invitation: Explainer on Large Load Tariffs for Data Centers with Q&A

COLUMBIA, SC - The South Carolina Small Business Chamber of Commerce and the Sierra Club are hosting a webinar, on background, for reporters in South Carolina on the importance of large load tariffs in protecting existing utility customers from rate shock due to power-hungry data centers. The purpose of the webinar is to have a conversation about the size and impact of data centers on the electric grid, impacts to existing customers, and how the South Carolina Public Service Commission (PSC) could adopt transparent safeguards for Dominion, Duke, and Santee Cooper customers following its opening of a large load docket.

Dominion and Duke allege they are protecting customers, however their deals with data center companies are currently secret. The Small Business Chamber of Commerce and the Sierra Club were part of settlement negotiations with Duke Energy that required a large load docket to be opened by the PSC no later than June 1, 2026.

The presentation portion of the webinar will be recorded, and the slides and recording will be shared by request following the event. An opportunity for Q&A with webinar participants will occur following the presentation, which will not be recorded.
