Pacific Gasoline & Electrical is asking state regulators to approve one other huge spherical of vitality storage procurements, together with its first large-scale contract for behind-the-meter batteries to serve grid wants.
The six tasks introduced Wednesday add as much as 387 megawatts, or 1,548 megawatt-hours, of vitality storage, together with two utility-scale solar-storage techniques in Southern California and three standalone battery installations throughout the state.
However the 27-megawatt/108 megawatt-hour behind-the-meter battery venture represents a departure from PG&E’s present roster of utility-scale storage contracts. The 15-year settlement requires Nexus Renewables U.S., a part of Ontario, Canada-based Nexus Renewables, to deploy a fleet of batteries at a number of websites in PG&E service territory, and supply them for grid companies beginning in August 2022.
PG&E’s announcement cites this deployment as an “AMCOR venture.” Amcor is an Australian-based firm that makes packaging supplies for meals and drinks, prescription drugs, private care and different merchandise, and has a number of amenities in PG&E’s Northern California service territory.
PG&E didn’t instantly reply to requests for extra data on the websites that might be focused for the behind-the-meter battery fleet.
This foray into behind-the-meter battery aggregation comes as a part of PG&E’s efforts to satisfy the California Public Utilities Fee’s name for vitality storage to assist stability the state’s more and more photo voltaic power-influenced grid.
Final yr, the CPUC ordered the state’s utilities and group selection aggregators (CCAs) to obtain a complete of three.three gigawatts of latest assets by 2023 to assist make up for the capability to be misplaced from the pending closure of pure gas-fired energy vegetation alongside Southern California’s coast.
PG&E and fellow investor-owned utility Southern California Edison have been inking huge battery and solar-storage contracts to satisfy this 2019 mandate, as have the state’s group selection aggregators (CCAs).
California’s rolling blackouts in August have pushed regulators to hunt out new assets, together with batteries, that may be introduced on-line rapidly to retailer grid energy for night peaks in grid demand, when the state’s photo voltaic era fades away but buyer demand for electrical energy stays excessive.
PG&E’s first procurements in Might contracted for 423 megawatts, or practically 1.7 gigawatt-hours, of vitality storage tasks. These tasks are set to come back on-line by August 2021, as are the seven solar-storage tasks including as much as 770 megawatts, or greater than three gigawatt-hours, of storage capability that Southern California Edison contracted this spring.
PG&E’s newest contracts for lithium-ion battery techniques with 4 hours of storage period are scheduled to come back on-line in 2022 and 2023, because the chart beneath reveals:
California’s rising want for multi-purpose behind-the-meter batteries
The 27 MW aggregation is the primary large-scale behind-the-meter battery venture for PG&E, however not for the state as a complete. Southern California Edison has contracted for 180 MW of behind-the-meter batteries underneath a 2014 plan to switch the capability misplaced from the closure of the San Onofre nuclear energy plant.
Behind-the-meter batteries can serve a number of features, from emergency backup energy and managing on-site energy consumption to cut back utility payments or improve the worth of photo voltaic, to offering system capability to transmission operators or native grid aid for utilities. California is a spotlight of those efforts to “stack” behind-the-meter battery values, and to create the brand new regulatory fashions to handle their interaction with current vitality markets and utility billing and tariff buildings.
SCE not too long ago contracted for a 5 MW behind-the-meter battery aggregation from Sunrun, set for 2023 supply. The main U.S. residential photo voltaic supplier can also be aggregating 20 MW of solar-storage techniques for 3 Northern California CCAs, to be used as grid assets and to help susceptible prospects with backup energy throughout wildfire-prevention energy outages.
California’s growing wildfire risk is forcing utilities to close off energy to excessive hearth threat areas, with PG&E prospects going through the brunt of the outages. The specter of blackouts has additionally pushed California prospects so as to add batteries to their photo voltaic techniques at a speedy tempo, aided by a CPUC mandate to direct profitable Self-Era Incentive Program (SGIP) battery funds to prospects deemed most susceptible to dropping energy.
PG&E emerged this yr from a 2019 chapter attributable to tens of billions of damages from wildfires attributable to its grid, and is working with the CPUC to search out clear vitality microgrid alternate options to the cellular diesel mills it’s deploying to again up blacked-out communities.
In the long run, California will want a large quantity of latest vitality storage to satisfy its objective of 100 p.c carbon-free vitality by 2045. A lot of the new solar energy coming on-line within the coming years can be matched with batteries to higher combine photo voltaic’s era profile with grid wants. Finally, the state may wish tens of gigawatts of longer-duration storage to cowl the gaps in era capability from the closure of its final fossil fuel-fired energy vegetation.
PG&E’s current storage tasks embrace a 300-megawatt/1,200-megawatt-hour venture by Vistra Power and a 182.5-megawatt/730-megawatt-hour venture from Tesla being constructed close to a natural-gas plant within the Monterey County group of Moss Touchdown.
