Tesla Opens Superchargers Before the Grid Is Ready With Flex Connect

Tesla is using PG&E's Flex Connect program in California to open Superchargers on spare grid capacity, before the utility's multi-year upgrades are finished. Sites run at full power when there is room and throttle down when the local grid is constrained, according to Tesla's charging account on X. Tesla says drivers should not be impacted, since sites typically run well below their maximum. Since this month, V4 cabinets connect directly to PG&E using IEEE 2030.5, an open standard, which allows setting power limits based on day-ahead forecasts.…

• Tesla estimates a typical project can open more than two years sooner with Flex Connect.
• Since this month, V4 cabinets use IEEE 2030.5 to receive power limits from PG&E.
