TVA issued an internal “Conservative Operations Alert” on Friday, indefinitely suspending all non-essential maintenance activities to minimize risk of power interruptions on TVA’s transmission system and generation facilities.
Late Sunday, TVA also initiated a “Power Supply Alert,” a precautionary declaration that an unexpected shutdown of a large generating unit or transmission system interchange could reduce TVA’s power supply reserves.
TVA is working with the region’s 155 local power companies and TVA’s directly served industrial customers to ensure an uninterrupted supply of electricity to the 9 million residents of the Valley. Electric demand is expected to be high on Monday and Tuesday, but below record levels.
Consumers can find immediate and long-term suggestions on how to reduce their energy usage and lower their power bills at TVA’s EnergyRight Solutions website and programs offered in collaboration with local power companies.
With regional temperatures forecast to be among the coldest in 20 years, TVA electricity demand is expected to exceed 31,000 megawatts on Monday evening and reach nearly 32,000 megawatts on Tuesday evening.
TVA’s all-time record winter demand was set on Jan. 16, 2009, at 32,572 megawatts when temperatures across the Tennessee Valley averaged 9 degrees. The all-time record demand on the TVA power system was 33,482 megawatts on Aug. 16, 2007, when temperatures averaged 102 degrees.
