Commissioning has taken place of a 100MW/400MWh vanadium redox circulation battery (VRFB) energy storage system in Dalian, China.

The most important undertaking of its sort on the earth right now, the VRFB undertaking’s planning, design and building has taken six years. It was linked to the Dalian grid in late Could, based on a report this week by the China Energy Storage Alliance (CNESA) industry group.

The system is in Dalian Metropolis’s Shahekou District, which is in Liaoning Province in northeastern China. It should contribute to reducing the height load on the grid in Dalian Metropolis and will even play a job at provincial stage, bettering energy provide and the aptitude to attach new technology sources like renewable energy to the grid.

VRFB developer and producer Rongke Energy provided the battery expertise. The corporate is a spin-off from the Dalian Institute of Chemical Physics of the Chinese language Academy of Sciences and the institute has overseen the undertaking by way of doctoral supervisor and head of its energy storage division Li Xianfeng.

Rongke Energy had been cited to be working with US-headquartered circulation battery expertise firm UniEnergy Applied sciences on the undertaking beforehand, however that firm’s Chapter 11 chapter was broadly reported late final yr and even its web site now seems to be offline.

An replace on the undertaking’s progress which was issued in June by the commerce group Zhongguancun Energy Storage Trade Alliance from Beijing stated the VRFB expertise was developed by the Dalian Institute of Chemical Physics crew.

Collectively, the lecturers have labored with Rongke Energy on virtually 40 business demonstration circulation battery tasks already, the alliance stated, together with tasks each in China and abroad, akin to a 10MW/50MWh system which was the world’s largest when accomplished in 2013 and a 10MW/40MWh undertaking at a wind farm.

Beforehand, the largest circulation battery set up on the earth was a 15MW/60MWh system deployed in 2015 in northern Japan by Sumitomo Electric. Sumitomo Electric brought online a second, 51MWh large-scale system in April this yr, which once more would nonetheless rank among the many world’s largest for a expertise which is regarded highly for its technical capabilities but has so far largely been unable to scale up.

Nevertheless, the Dalian undertaking is, in addition to being an illustration undertaking and a part of a wave of large-scale VRFBs China is seeking to deploy, solely at its first part of building. A second part will deliver it as much as 200MW/800MWh.

Scale of China VRFB tasks dwarf the rest on the earth to date

It was the primary undertaking to be authorized beneath a national programme to build large-scale flow battery demonstrations around China again in 2016 because the nation’s authorities launched an energy storage coverage technique. It’s thought that numerous components together with surprising volatility within the value of vanadium and demand for the metallic in different industries like building had slowed the programme considerably based on sources Energy-Storage.information had spoken to beforehand.  

Elsewhere, in China’s Hubei Province, one other (very) large-scale VRFB is being inbuilt phases that was authorized by way of the identical programme. Canada-headquartered VRB Energy is establishing that 100MW/500MWh facility, with a ceremony held to signal the start of construction in August last year for an initial 100MWh phase.

VRB Energy and its native companions had already constructed a profitable 3MW/12MWh demonstration undertaking in Hubei and a VRFB factory with 1,000MWh annual production capacity could be built on the web site at a later date too.

The Hubei undertaking’s price for 500MWh of VRFB, together with a mixed 1GW of {solar} PV and wind technology from which it’s going to cost, was cited as round US$1.44 billion.

The primary part of Rongke Energy’s Dalian undertaking in the meantime was given as RMB1.9 billion (US$298 million) in CNESA’s announcement, equal to RMB4.75/Wh (US$0.7/Wh).

Though not on the dimensions individually of both Chinese language undertaking, some megawatt-scale circulation battery tasks have been accomplished, introduced or begun building in latest months all over the world.

Within the UK, the world’s largest battery storage system to hybridise lithium-ion and vanadium circulation went formally into business operation this summer season, pairing 50MW/50MWh of lithium with a 2MW/5MWh VRFB system.

The circulation battery firm behind that undertaking, Invinity Programs, can be supplying Australia’s first grid-scale circulation battery storage, a 2MW/8MWh system co-located with a 6MWp {solar} PV plant in South Australia. Invinity may also provide a 2.8MW/8.4MWh battery storage system at a demonstration project in Alberta, Canada.

On the bigger finish of the dimensions, California non-profit energy provider Central Coast Neighborhood Energy (CCCE) picked three VRFB tasks as a part of a procurement of sources to come back on-line by 2026, ranging from 6MW/18MWh to 16MW/128MWh and totalling 226MWh.

One factor limiting the scale and scale of circulation batteries right now is entry to vanadium pentoxide, which is used of their electrolytes. Whereas vanadium itself is abundant in both its raw primary form and as a secondary byproduct of steel production, not many services to course of it into electrolyte exist.

This has led some circulation battery firms like Austria’s CellCube and others to focus on the commercial and industrial (C&I) and microgrid segment of the energy storage market, a minimum of in the meanwhile.

Clearway inaugurates Hawaiian island’s first large-scale solar-plus-storage plant



Clearway inaugurates Hawaiian island’s first large-scale solar-plus-storage plant

Clearway Energy Group has introduced on-line the primary ever utility-scale solar-plus-storage venture on the Hawaiian island of O’ahu.

Set up of {solar} PV modules and batteries was accomplished forward of schedule on the US$140 million venture, the developer and impartial energy producer (IPP) stated final week as its introduced commissioning of the Mililani {Solar} I plant.

The ability plant combines 39MW of {solar} PV with 39MW/159MWh of battery energy storage system (BESS) know-how. Clearway signed 20-year energy buy agreements (PPAs) with Hawaiian Electric Firm (HECO) in 2018 for Mililani {Solar} I and Waiawa {Solar}, a separate 36MW PV, 36MW/144MWh BESS venture additionally on O’ahu.

Construction on both plants began in April 2021, Energy-Storage.information reported on the time, with Moss {Solar}, the {solar} division of infrastructure firm Moss employed as building contractor.

Wärtsilä Energy equipped the battery storage. In July, the Finnish energy storage system integrator and producer introduced its involvement in each Clearway’s O’ahu initiatives, in addition to three initiatives for the developer in California.

Collectively the Clearway projects will see Wärtsilä supply 500MW/2,000MWh of BESS. The three California crops are all solar-plus-storage too, with one a retrofit to an present {solar} plant and two new-build {solar} farms positioned adjacently on the web site of two retired fossil gasoline crops within the state’s San Bernadino County. These crops are scheduled to come back on-line subsequent 12 months.

The Hawaii crops’ solely software will likely be {solar} load-shifting, Wärtsilä Energy VP of energy storage and optimisation Andy Tang informed this web site in a latest interview. The four-hour period batteries will retailer energy generated in the course of the day to assist mitigate night and night-time electrical energy use and kick into play to ease the utility’s interval of {solar} ramp down every day.

For Clearway’s initiatives, Wärtsilä put in its personal GridSolve Quantum BESS answer, because it does for all its grid-scale battery initiatives. GridSolv Quantum consists of the GEMS Digital Energy Platform energy administration system (EMS) and is provided with lithium iron phosphate (LFP) battery cells.

O’ahu has been residence to Hawaii’s solely coal energy plant, which is within the means of being taken out of service and being changed with {solar} and batteries. Hawaii can be concentrating on 100% renewable energy by 2045 and is already one of many highest {solar} adopters per capita within the US, significantly for residential rooftop PV.

Since HECO signed the renewable energy PPAs in 2018 which Clearway’s initiatives had been amongst, the utility has undertaken a few procurements by way of Requests for Proposals (RfPs) to contract for about 5GWh of battery storage, alongside {solar} PV.

Energy-Storage.information reported earlier this month as AES Corporation broke ground on two more large-scale solar-plus-storage plants in the state, one a 60MW PV plant with 240MWh BESS on Maui and the opposite a 30MW PV plant with 120MWh BESS on Hawaii Island.

Clearway commissioned three earlier {solar} PV-only initiatives in Hawaii in 2019, two on O’ahu and one on Hawaii Island. When each new solar-plus-storage crops are on-line, the corporate’s put in PV base within the state will complete 185MW.

230MW BESS comes online at Bureau of Land Management site in California



caiso california nextera desert sunlight energy storage

A 230MW battery energy storage system (BESS) from NextEra Energy Assets, half of a big solar-plus-storage challenge, has come on-line in California.

The Bureau of Land Administration (BLM), which manages the land on which the 94-acre challenge is positioned in Riverside County, announced the beginning of economic operations on the Desert Daylight Battery Energy Storage System yesterday (16 August).

The 230MW BESS challenge adjoins the prevailing Desert Daylight {Solar} Farm and can retailer renewable energy generated by the Farm and shift it to peak demand hours.

In a doc approving the project in November last year, BLM mentioned the challenge developer was Daylight Storage, LLC, a subsidiary of NextEra Energy Assets, which seems to have been very quiet on the challenge.

An SEC filing from the Fortune 500 company, referring to the project as the Sunlight Storage Facility, mentioned it’s a 230MW/920MWh system. A four-hour period is a requirement for initiatives in California to supply energy to utilities by means of Useful resource Adequacy, the framework by which grid operator CAISO ensures provide can meet demand, and the primary income stream for BESS initiatives.

The challenge’s commissioning is sweet information for the state after one thing of a slowdown in BESS deployments in the lead-up to the peak summer season, when the heightened danger of wildfires may also threaten grid reliability and enhance the possibility of outages.

As of the top of July, CAISO had 3,334MW of grid-scale BESS in industrial operation in keeping with its official knowledge (which will be modified retrospectively if a unit’s industrial operation date is introduced considerably after the very fact).

It’s not clear if these figures embrace the Desert Daylight BESS, which it’d do whether it is asserting its industrial operation late, for instance. Assuming not, this brings the BESS depend in California to just about 3,600MW. If Ameresco’s 537.5MW/2,150MWh initiatives for utility SCE had not been delayed, as reported by, the determine might have been over 4,000MW by now, the grid operator’s stated aim.

The BLM is the US authorities physique liable for administering federal lands, a key determine in approving initiatives positioned inside its portfolio. Latest important solar-plus-storage initiatives it has waived by means of embrace a 250MW project by Revolve Renewable Power and a 500MW project by Oberon Solar, each lined by our sister web site PV Tech.

The company can be encouraging initiatives to be constructed on its land, most just lately issuing a solicitation for utility-scale solar projects on 90,000 acres of public land throughout Colorado, Nevada and New Mexico.
