Recently, GE Vernova completed a study to demonstrate the consumer benefits of greater interregional transmission given more frequent extreme weather events and the shift to lower carbon resources.
- GE Vernova illustrated that greater interregional transmission provides affordability, reliability and resiliency benefits while also proposing a methodology that regulators could consider, to quantify the amount of incremental transmission required.
- GE Vernova simulated electric generation across the US Eastern Interconnection for a number of weather conditions in the 2035-2040 timeframe in order to quantify the benefits of greater interregional transmission to resiliency, affordability and stability.
- During a simulated heat wave in August 2035, greater transmission prevented ~740,000 customers losing power across New York City and Washington, DC saving $875M.
- During a simulated polar vortex in February 2035, greater transmission prevented ~2 million customers losing power across Boston, New York City, Baltimore and Washington, DC saving $1B.
- Under normal weather conditions, greater transmission saved $3B/year in 2035 increasing to $4B in 2040 via greater access to lower cost generation.
- Example cost benefit analysis shows $12B in net benefits from 87GW of incremental interregional transmission.
- Grid stability is also increasingly a risk during extreme weather events. Alternate interregional transmission technologies (e.g. DC vs AC connections) should be considered to maintain stability especially with high inverter-based resource penetrations.
