California Calls for Three.3GW of New Assets by 2023 to Meet Looming Grid Shortfall

California Calls for Three.3GW of New Assets by 2023 to Meet Looming Grid Shortfall

California regulators have authorised a Three.Three-gigawatt “all-source” procurement that can pit new renewables, power storage, demand response and different clear sources towards pure gas-fired energy vegetation in a race to satisfy what might be a serious shortfall in grid capability within the subsequent 4 years. 

Thursday’s choice from the California Public Utilities Fee units the stage for each utility, group alternative aggregator (CCA) and third-party direct entry (DA) supplier within the state to safe a share of sources wanted to maintain the grid operating throughout instances of peak demand.

The all-source procurement is technically open to current pure gasoline vegetation. However carbon-free options are prone to be the first beneficiary of the brand new alternatives the choice will open up. These embrace photo voltaic paired with batteries to shift its daytime output to late afternoon and early night, when California faces its steepest demand peaks, and demand response that shifts power consumption away from these crucial hours.

However the CPUC’s choice additionally contained the controversial choice of preserving a set of pure gas-fired energy vegetation open previous their present 2020 closure dates, a transfer opposed by native environmental justice teams and clear power advocates alike. Opponents have vowed to problem that a part of the plan with state coastal water authorities, which ordered the closure of the once-through cooling (OTC) vegetation within the first place. These vegetation use seawater for cooling, which was deemed environmentally dangerous. 

In response to forecasts from state grid operator CAISO, a mixture of nuclear energy plant closures, natural-gas system constraints, uncertainty over the worth of solar energy and electrical energy imports from different states within the coming years, and different elements, may depart the state with a capability shortfall of not less than 2.Three gigawatts by 2022. Utility Southern California Edison, which serves the area hardest hit by these elements, has projected an excellent deeper shortfall — as a lot as 5.5 gigawatts by 2023, together with the retirement of OTC capability. 

The CPUC’s new choice expands considerably past its September proposal for a 2.5-gigawatt procurement, which centered on utility Southern California Edison and CCAs in its territory. 

As a substitute, the CPUC is counting on utilities, CCAs and DA suppliers throughout the state to acquire their share of sources, based mostly on a measure of their share of system load. Every might want to procure half of their complete by 2021, 75 p.c of it by 2022, and all of it by 2023. 

Whereas teams together with the California Group Alternative Affiliation (CalCCA) have questioned the evaluation behind the shortfall projection, “we view the requirement for added procurement now as a “least regrets” technique, since electrical energy shortages would most definitely result in regrets,” the CPUC wrote.

Southern California Edison will nonetheless be liable for the lion’s share of the procurement, with 1.18 gigawatts of incremental procurement. However bankrupt Northern California utility Pacific Gasoline & Electrical, which has been shedding prospects, and thus load, to CCAs in its territory, will likely be liable for 717 megawatts, and San Diego Gasoline & Electrical, which is dealing with the creation of a metropolis of San Diego CCA that may represent greater than half its buyer base, could be liable for 239 megawatts. 

CCAs have been taking up an rising share of consumers from California’s investor owned utilities. Beneath the CPUC’s Built-in Useful resource Plan (IRP) continuing, which spawned this new procurement, CCAs are anticipated to acquire about 10 gigawatts of the projected 12 gigawatts of extra carbon-free era the state will want by 2030. 

Beneath Thursday’s choice, CCAs throughout the state will likely be liable for roughly one-quarter of the three.Three-gigawatt procurement. A few of the largest embrace almost 200 megawatts for Clear Energy Alliance of Southern California, almost 100 megawatts for East Bay Group Vitality, 78 megawatts for San Jose Clear Vitality, 67 megawatts for Silicon Valley Clear Vitality, and about 55 megawatts apiece for Peninsula Clear Vitality and Clear Energy San Francisco, to call just a few. 

CCAs have already got been signing new renewable power contracts at a fast clip. This week, CalCCA introduced that its members have contracted for almost Three.2 gigawatts of renewable energy buy agreements, virtually all of it utility-scale photo voltaic. Whereas standalone photo voltaic doesn’t present almost as a lot capability worth because it as soon as did, CCAs have additionally inked contracts for 239.5 megawatts/788 megawatt-hours of power storage, greater than half of it within the final 12 months. 

Of this battery capability, 86 p.c is co-located with photo voltaic that costs batteries to be used later within the night, making it doubtlessly appropriate for service as grid capability. These contracts, in addition to others that haven’t but been counted within the CPUC’s baseline, will likely be eligible for assembly its new procurement targets, so long as they’re capable of present the capability providers required.
