WattEV's Fresno depot goes live two years early - powered by Ampcontrol EMS

On June 30, 2026, WattEV opened the first public heavy-duty electric truck charging depot in Central and Northern California — its seventh in the state — on the Highway 99 corridor in Fresno, and the first of four planned Northern California sites linking the Ports of Oakland and Stockton with Central Valley freight hubs. The depot runs seven MCS megawatt fast-chargers and fifteen single-cord 240 kW CCS chargers.

Ampcontrol provides the energy management system that runs the site, and it is the product PG&E approved under its Flex Connect program. By managing charging load in real time against available grid capacity, the EMS lets the depot access up to 3.6 MW during most hours of the year — even though only about 1 MW of firm capacity is available today. A permanent capacity upgrade is scheduled for mid-2028; until then, flexible load management keeps the trucks charging and freight moving.

The result is a depot online roughly two years ahead of a traditional interconnection timeline. As a PG&E Flex Connect certified solution provider (IEEE 2030.5 / CSIP), Ampcontrol helps fleets and utilities electrify faster while making better use of the grid capacity already in place.

"Grid capacity shouldn't decide when freight gets to go electric. Our energy management system lets WattEV's Fresno depot draw the power it needs today by flexing load around what the grid can give — years before the permanent upgrade arrives. We're proud to be PG&E's Flex Connect–approved partner and to help open a zero-emission freight corridor through the San Joaquin Valley."
