More Interregional Transmission Could Have Saved Nearly $1 Billion, Preserved Power for 200,000 Homes During Texas Freeze

Each additional gigawatt (GW) of transmission capacity connecting the Texas power grid (ERCOT) with neighboring states in the Southeast could have saved nearly $1 billion and kept the heat on for approximately 200,000 Texas homes during Winter Storm Uri in February of 2021, according to a new report released today by the American Council on Renewable Energy (ACORE). The report, Transmission Makes the Power System Resilient to Extreme Weather, details the value additional transmission would have provided during five severe weather events in Texas, the Northeast and the Midwest between 2014 and 2021.
The report found that additional transmission ties would have generated significant cost savings for consumers and reduced outages during recent extreme weather events by canceling out local fluctuations in the supply and demand of electricity and providing alternative sources of power in an emergency.
“As severe weather events become more frequent, our balkanized power grid is increasingly unable to deliver reliable electricity to consumers who need it,” said ACORE President and CEO Gregory Wetstone. “This report demonstrates that we are already paying an enormous price for our lack of interregional transmission, and that the benefits of a robust transmission grid would quickly surpass the cost of constructing new lines. It is time to implement pro-transmission policies to enable the investments we need to strengthen our grid, lower costs for consumers and reduce power outages during extreme weather events.”
