Utility Size Batteries

Southern California Edison would like its next round of energy storage systems,
. . . to be standard size "Plug & Play" packages,
. . . to fit into fast-changing distribution grid project-planning cycles.

“It’s a faster move toward catalog or off-the-shelf” purchasing,
. . . it's the same way that utilities order transformers, and
. . . other standard grid gear today.

Under California state law AB 2514:
. . . . . . Southern California Edison,
. . . . . . Pacific Gas & Electric, and
. . . . . . San Diego Gas & Electric,
. . . must install 1.3 gigawatts of storage by decade’s end.
Each utility has issued RFPs to meet its first biannual procurement targets.

But all of these projects to date, have been targeted for specific sites, and
. . . preplanned to meet specific grid needs,
. . . with lead times that stretch into multiple years.
This new RFP is meant to collapse all of these constraints,
. . . it has much more flexibility built into where its new batteries will end up, and
. . . “We’re trying to get people to price the cost of transportation,
. . . to places that encompass our entire service territory,” and
. . . “We’re doing distribution deferral.”
(charging batteries at off-peak hours,
. . . then discharging them to bolster grid circuits,
. . . that would otherwise require expensive upgrades to wires and transformers,
. . . to manage peak loading conditions)

Look at all the money Utilities will save,
. . . by storing the "Rejected Energy" on the chart,
. . . in the batteries, for later use.
