A brand new report from the Lawrence Berkeley National Laboratory of the US Department of Energy (DoE) reveals a big enlargement of solar-plus-storage services within the US energy plant market.
From pv journal USA
Within the United States, information from the Lawrence Berkeley National Laboratory’s vitality market and coverage workforce (EMP) reveals that there are at the moment 469 hybrid energy vegetation working within the United States.
About 61% of hybrid vegetation, or 288 services, are solar-plus-storage initiatives. These vegetation characterize the vast majority of vitality storage capability, with 7.8 GW and 24.2 GWh of vitality deployed throughout the nation. By 2023, 66 out of 80 new hybrid initiatives might be PV-plus-storage programs.
“Hybrid Power Plants: Status of Operating and Proposed Plants 2024 Edition” attracts on information from the Energy Information Administration (EIA) of the US DoE, in addition to annual studies on the nation’s interconnection queue.
The enlargement of solar-plus-storage services gained momentum in 2020, initially pushed by small initiatives in Massachusetts. This development is amplified in California, Texas and Florida, the place the introduction of bigger services has elevated total capability. Notably, Massachusetts hosts 89 of the nation’s 288 solar-plus-storage services, every with lower than 7 MW of capability. These installations are inspired by the state’s SMART program, which promotes vitality storage with useful DC to AC ratios and battery integration.
California follows because the state with the second highest variety of solar-plus-storage services, totaling 72. Unlike Massachusetts, almost half of those West Coast services exceed 100 MW of photo voltaic capability. Arizona and California led the best way within the variety of new solar-plus-storage hybrid vegetation, with 15 and 16 new services coming on-line, respectively.
The use of vegetation is rising, normally and generally individually. There is a nationwide shift from the first use of vitality storage for frequency regulation to its larger use for arbitrage, accompanied by a rising discount in photo voltaic services. This is particularly necessary in solar energy vegetation the place storage helps in extracting vitality that may be prevented and stabilizes the technology profile of photo voltaic services.
The EMP report comprises case research of particular person energy vegetation, together with Blythe Solar II and Meyersdale Windpower, with detailed efficiency information proven within the graphs beneath. Blythe Solar II, a 131 MW (AC) photo voltaic plant with 115 MW / 528 MWh storage, added storage in 2021 to the 2016 photo voltaic infrastructure. The plant cycles its batteries lower than as soon as per day, aligning them with peak photo voltaic hours and nighttime demand for vitality arbitrage that matches CAISO wholesale pricing and photo voltaic shifting. However, the EIA lists frequency regulation as the first perform of the plant, with arbitrage as secondary.
Meyersdale Windpower, a 30 MW wind facility with 18 MW / 12.1 MWh batteries added in 2015, operates individually from Blythe. Its battery cycles on common six instances per day, and as much as twelve instances underneath sure situations. The EIA identifies frequency regulation as the first and solely use of Meyersdale’s battery, according to its fixed biking.
On the entrance, the capability is clear and mixed with storage.
In California, the utility-scale photo voltaic market has successfully reworked right into a solar-plus-storage market, with virtually all new initiatives that includes hybrid programs. The residential PV sector can also be catching up, with a 60% storage attachment fee.
The report says the nationwide interconnection queue is transferring towards California’s hybrid energy plant mannequin. Currently, 47% of future capability is deliberate as hybrid vegetation, with 92% solar-plus-storage services. Of the overall 2.5 TW within the queue, 2 TW are photo voltaic and storage configurations, both standalone or hybrid, signaling a future dominated by these applied sciences.
Future tendencies in vitality storage pricing, which have seen important declines and are anticipated to proceed, are driving these submissions to the interconnection queue. By 2024, photo voltaic investments are anticipated to exceed $500 billion, making certain the expansion of solar-plus-storage services by means of decrease {hardware} prices and improved photo voltaic module effectivity.
However, within the quick time period, pricing for solar-plus-storage services has skilled a slight improve.
The EMP workforce analyzed pricing information from 105 solar-plus-storage energy buy agreements, representing 13 GW of photo voltaic and seven.8 GW/30.9 GWh of vitality storage. The worth for hybrid programs has elevated since 2020, partly resulting from larger battery storage capability, pushed by the price of extra lithium storage time. Although adjustments in battery utilization complicate the evaluation, provide chain inflation additionally seemingly contributed to the worth improve.
Despite these rising prices, the rising variety of new vitality storage initiatives reveals that the market stays steady, with capability persevering with to develop.
