Estimating the Need for New Gas Capacity in the Southeast

Client:

The FERC approved the Atlantic Coast Pipeline (ACP) in 2017. Project owners Duke and Dominion filed a certificate for a construction extension with FERC on June 16, 2020. On behalf of the Southern Environmental Law Center, Synapse assessed the projected demand for new gas used for electric generation, estimating the “maximum demand for new gas” on a peak winter day in Dominion’s and Duke’s service territories. We examined public IRPs, new policies in Virginia and North Carolina that will lower CO2 emissions in the electric sector, and public documents related to the utilities’ internal emission reduction goals. We used that data to build spreadsheet models to assess maximum future gas demand on a winter peak day. Our analysis demonstrates that the need for new gas-fired generating resources originally anticipated by Duke and Dominion has not and will not materialize, thus negating the utilities’ claimed need for the ACP.
