The US Department of Energy has identified a range of technological adaptations which have the potential to add between 20 GW and 100 GW of effective transmission capacity. We would guess that would avoid tens of billions of dollars of transmission investments. One technology which the report covers, Dynamic Line Rating (DLR) by itself increases effective transmission by 10%-30% with only a three-month lead time and 5% of the Capex of building the line at the uprated capacity. Transmission is the primary obstacle to the US energy transition, and permitting and lead times – not needed for these kinds of upgrades – are the primary obstacle to transmission, which may need to double by 2035 if the energy transition stays…
