ELECTRICITY DEMAND HITS NEW ALL-TIME PEAK FOR GEORGIA COOPERATIVE ENERGY SYSTEM

System meets historic demand over holiday weekend

TUCKER, Ga., Jan. 3, 2023 /PRNewswire/ -- Today Oglethorpe Power, Georgia Transmission and Georgia System Operations announced that a new all-time peak electricity demand was reached between 8 and 9 a.m. EST on Saturday, Dec. 24, 2022. This preliminary new record peak of 11,034 megawatts (MW) is almost 8% higher than the previous record of 10,241 MW, set on June 15, 2022.¹ Together Oglethorpe Power, Georgia Transmission and Georgia System Operations provide wholesale energy generation, transmission and system operations to 38 consumer-owned, not-for-profit electric distribution cooperatives across Georgia. These cooperatives serve electricity to approximately 4.4 million Georgians in 151 of 159 counties.

The historic electricity demand occurred during extreme winter weather conditions across Georgia, with temperatures plunging to a single digit across much of the state. Oglethorpe Power, Georgia Transmission and Georgia System Operations maintained reliability and had sufficient generation to meet the new all-time peak electricity demand for the 38 electric cooperatives they serve.

Prior to 2022, the all-time peak for Georgia's cooperative energy system was set in 2019 at 9,701 MW.

Oglethorpe Power President & Chief Executive Officer Michael L. Smith attributed the companies' ability to reliably meet the record electricity demand to a diverse portfolio, preparation and teamwork.

"Fuel diversity is critical to reliability in extreme weather," said Smith. "In these conditions we needed every resource: fossil fuels, hydro, nuclear and solar. Our operations and fuels teams took proactive steps to prepare for the extremely cold temperatures and our crews worked around the clock to quickly repair generation units that tripped due to the weather."

Georgia Transmission President & Chief Executive Officer Barbara Hampton said crews were stationed throughout the state to make immediate repairs of high-voltage transmission equipment damaged by the frigid temperatures and extreme wind. 

"We are dedicated to serving our members and their communities through flexible and responsive service," Hampton said. "That commitment, along with ingenuity and determination, was on full display as our operations and maintenance associates worked tirelessly in the unprecedented weather conditions to help keep the lights and heat on for homes and businesses across Georgia during the holidays." 

"Georgia System Operations played a pivotal role in ensuring our Member Systems' members were never without power during the recent arctic blast," said company President & Chief Executive Officer Greg Ford. "This was due to the hard work of employees and close collaboration among the three organizations that are charged with ensuring uninterrupted power flow."

Oglethorpe Power's SEC filings reflect peak load at the meter point, or sales to members, which is net of transmission losses, and include approximately 14 MW of member load in Florida. Oglethorpe Power's SEC filings will reflect corresponding peak loads of approximately 10,811 MW on Dec. 24, 2022 and 10,017 MW on June 15, 2022.
