China is targeting a non-hydro energy storage installed capacity of 30GW by 2025 and grew its battery production output for energy storage by 146% last year, state media has said.

The statement from the National Development and Reform Commission (NDRC) and the National Energy Administration said the deployment is part of efforts to boost renewable power consumption and ensure grid stability.

The 30GW figure includes all storage processes using electrochemical, compressed air, flywheel and supercapacitor systems but not pumped hydro although plans to increase the latter substantially have also been reported.

The country is aiming for 50% electricity generation from renewable power by 2025, up from 42% currently.

Wei Hanyang, a power market analyst at research firm BloombergNEF, said lithium-ion costs will come down to help China’s goals: “While the cost-learning curve is still relatively slow now, the 14th Five-Year-Plan (2021-25) has made a clear goal for the per unit cost of energy storage to decrease by 30 percent by 2025. This will hopefully accelerate the industry pace.”

Meanwhile, the State Grid Corporation of China (SGCC) reportedly plans to increase its capacity of battery storage to 100GW in 2030 from 3GW today, and do the same for pumped hydro storage from 26GW today. That is according to SGCC chairman Xin Baoan in a Chinese-language commentary published in the state-owned People’s Daily.

China overall is targeting 120GW of pumped hydro by 2030, according to the National Energy Administration.

If true, these 2030 figures would completely blow out of the water recent forecasts on installed storage power capacity in the Asia-Pacific region, like those in Guidehouse’ recent report, which pegged the figure at just 74GW.

As with other countries, pumped hydro is the vast majority of energy storage GW installed in China today.

The Ministry of Industry and Information Technology has also recently revealed that China’s production output for lithium-ion batteries for energy storage reached 32GWh in 2021, up 146%. That is 10% of its total lithium-ion battery output, which was 324GWh, a 106% increase resulting in a market worth 600 billion Yuan (US$95 billion).

The country dominates the global lithium battery supply chain although Europe and the US are both making large strides to increase domestic production to be less reliant on importing from the Far East.

The world’s largest combined lithium-vanadium battery energy storage system (BESS), the Energy Superhub Oxford (ESO), is about to start fully trading in the UK’s electricity market, showcasing the potential of hybrid assets.

ESO is the subject of a 3,000-word feature in this quarter’s PV Tech Power newsletter from our sister site PV Tech. It has the largest lithium-vanadium hybrid BESS in the world at 55MWh and the largest tertiary connection to the UK grid.

The 50MW/50MWh lithium-ion system from Wartsila has been trading in the UK electricity market since mid-2021 and Invinity Energy Systems’ 2MW/5MWh vanadium redox flow battery is set to join it imminently, having been energised in December.

The two will operate as one hybrid asset after a lead-in period of 3-6 months where they’ll operate separately. The hybrid system will be uniquely placed to capitalise on opportunities in both the merchant and ancillary services markets, executives at Invinity, trader and optimiser Habitat Energy and project developer Pivot Power told Energy-storage.news.

In the merchant space, the vanadium could capture margin spreads which might be smaller but over longer periods of time while the lithium could capture value in volatile conditions with larger spreads but shorter time periods.

“Being able to access both sets of value with the same asset is a real positive for this project and something we’re really looking to investigate and explore,” Habitat Energy’s head of UK businessdevelopment Ralph Johnson said.

New pre-fault, higher-output ancillary services like dynamic regulation (DR) and dynamic moderation (DM) will be accessible for the vanadium flow battery thanks to its longer duration, the interviewees told Energy-storage.news.

ESO, which received a £11.3 million (US$15 million) grant from Innovate UK, also comprises an EV charging station and 60 ground source heat pumps although both of those connect directly to the National Grid substation rather than the BESS itself.

Projects like SK Innovation & Ford’s Blue Oval City will substantially grow the US’s domestic li-ion manufacturing capacity. Image: Ford.

Nearly 4.2GW of battery storage capacity was added to the US grid in 2021, according to a new report from BloombergNEF which also looked at growth in the country’s lithium-ion manufacturing capacity.

The ‘Sustainable Energy in America Factbook’, produced for The Business Council for Sustainable Energy, says the figure is more than in all preceding years combined.

Non-hydro, i.e. battery energy storage deployments, grew 360% to 4,417MW although it says that only 77% of this is ‘confirmed’ with the remainder ‘estimated’. It brings the US’ cumulative total battery storage deployment to 6.6GW. The report highlights two main drivers of growth.

First, there is a growing need for storage in energy-shifting applications due to rising renewables on the grid, particularly California’s. And on the regulatory side, the Federal Energy Regulatory Commission (FERC) Order 841 (2018) removed barriers preventing storage from fully participating in those markets, providing a further tailwind to the sector.

Though it cautions that with the higher penetration rate of batteries comes increased pressure to deliver on meaningful system-level impacts on the grid and power markets. Pumped hydro is around 80% of storage capacity in the US today but has been close to flat since 2004, today sitting at around 22.5GW.

BloombergNEF’s report covers all segments of the battery storage market including residential, which saw 19,607 installations in the first nine months of 2021, two-thirds and 1.5x higher than the same period in 2020 and 2019 respectively.

US lithium-ion battery manufacturing capacity also increased, growing to 60GWh/year in 2021. It is expected to reach almost 100GWh/year by the end of 2022, though BloombergNEF does not forecast any further ahead.

However, it notes that joint-venture projects by SK Innovation/Ford’s Blue Oval City and Samsung SDI/LG Energy Solution will add 129GWH by 2027 and 40GWh by 2025/25, respectively. These nearly triple the manufacturing capacity figure on their own.

BloombergNEF’s reports’ broader brief and methodology makes for more positive reading than the American Clean Power Association’s (ACP) recent report, which only covered utility-scale deployments and said that clean power installations fell 3% last year to 27.7GW after a particularly poor last quarter.

BloombergNEF says that overall, new renewable energy capacity deployments grew 5% to 37.3GW in 2021. This figure doesn’t include storage, without which the ACP’s annual deployments figure would have been even lower.

The battery storage sector employed 67,000 people at the end of 2020, though this is likely to be much higher considering the deployment levels the following year. Around 10% of its workforce is unionised, in line with solar and wind.

Even Tesla needed to put its EV operations’ demands ahead of its own BESS business last year. Image: SRP.

Energy storage system integrators are diversifying their procurement strategies to ease supply chain constraints, with the electric vehicle (EV) market a bigger priority for battery cell and module suppliers.

Integrators are starting to procure or consider using Tier 2 battery makers’ products, as investors become “comfortable with the level of risk involved in this market,” Oliver Forsyth, analyst for IHS Markit, told Energy-Storage.news. 

“If you subtract the amount that will go to the automotive sector, there isn’t a lot leftover for the stationary market. For the system integrators and developers to continue to compete for that small segment left of supply is going to be challenging over the next two, three years, until new factories and manufacturing capacity is built out,” he said. 

Forsyth spoke recently about the growing level of competition between energy storage system integrators — including new entrants to the space from developers to battery makers that have diversified into the space — after IHS Markit published its annual survey on the 2021 system integrator landscape.

The major players are able to secure long-term battery supply deals: top-ranked integrator Fluence said ahead of its IPO last year that it has secured 20GWh of supply until the end of 2024. The company also has a partnership with Northvolt, which has the first of its gigafactories in Europe ramping up by the end of that timeframe. Even so, it recently announced future contracts will be signed pegged to raw materials index-based pricing.

Powin Energy, also in the top 10 ranking, has got multi-year deals with Chinese cell manufacturers CATL and EVE Energy. 

“The important thing to realise here is just how small a market the stationary energy storage market is relative to EVs,” he said.

Even the biggest companies in the space will be de-prioritised against electric transport sector customers, which is “just something that the stationary market needs to get used to”.

Even Tesla, again highly-ranked in the survey, which produces its own cells is not immune, with the company’s leadership having revealed that its own EV division had to take priority over stationary storage last year for materials supply. It still managed to deploy nearly 4GWh of storage in 2021.

In the short term, it makes sense then to diversify or expand the base of suppliers, which IHS Markit is seeing across the system integrator landscape. System integrators are starting to sign contracts and long-term MOUs with Tier-2 suppliers, he said. 

“It makes sense because you don’t want to be stuck with one supplier for competitive reasons. For pricing, you don’t want them [suppliers] to have that kind of price control over you. But also, from a risk perspective, if for some reason they cannot honour that agreement, you want to be able to know that you can turn to someone else.”

Historically there has been a very small pool of bankable Tier-1 cell suppliers, perhaps as few as four, but lenders and investors are starting to be a bit more comfortable working with suppliers outside that bracket. 

It helps also that many of those investors are not that new to the market any more. Some have experience over multiple projects and portfolios and have started to understand and be happy to take on the level of risk involved, Forsyth said.

Those more experienced investors have started to consider going with cheaper Tier-2 options. That applies for their choice of system integrator as much as it does their integrators’ selection of cell suppliers. 

“When you come to financing, if who you’re trying to get involved in someone [for whom it is] their first time investing in battery storage, they sometimes want security, they want to be able to know that this project is in good hands.”

“That is when your Tier-1s just come into play — but then we’re seeing, more and more where there’s been people investing into multiple battery projects now, they are getting comfortable with the level of risk involved in this market. They start to think, ‘Okay, we are comfortable, we understand this technology. Potentially, we can try to find a lower cost partner,’

“… and that’s where potentially some of these newer system integrators — or if you’re looking at the battery manufacturing space, some of the Tier-2 cell providers — come into play. We start to see people willing to take that risk and try to test out some of these newer players, because they are sometimes cheaper and that is an advantage for them.”

Countries in West Europe are mutualising a secondary reserve service and storage could be a big winner. Image: Sutthipong Kongtrakool

Energy storage could garner a market share of one-third by 2025 for the new, pan-European automatic frequency restoration reserve (aFRR) market, which is set to launch in the middle of this year with France and Germany sharing their capacity first.

That is according to Corentin Baschet of consultancy Clean Horizon, which has done a lot of work on an upcoming project called PICASSO which will mutualise aFRR services across West Europe. He told Energy-Storage.news that France and Germany will kick things off by mutualising their services around the middle of 2022, a bit later than initially planned (Q1).

The project has trigged a review of market rules which exclude storage from participating in the main European secondary reserve market in most countries, something which is expected to change with the new aFRR scheme’s launch and rollout.

“Increasing the participation of battery storage is definitely one part of Picasso but it’s not at the forefront of their mind, there will still be loads of conventional assets participating,” Corentin said.

“By 2025, we think a third of the aFRR market in West Europe could be for battery storage if the rules and price signals are improved. So that could be something like 500MW for storage in aFRR in Germany alone where the aFRR services market represents a volume of 1.5-2GW.”

He says that the rules in Belgium are much more friendly to storage and today there are more than 30MW of batteries active in the aFRR market, including a 10MW system optimised by Centrica Business Solutions which joined in December.

“More than 200MW of storage will be deployed in Belgium to address this opportunity,” he says, adding that 130MW/450MWh of projects were awarded in the recent capacity market auction.

The aim of sharing aFRR across borders is to reduce the cost of provision, he explains. “It might be that France has more expensive AFRR than Germany has, so if you export energy activation across borders that reduces the cost of ancillary services, which ultimately reduces the cost for the consumer. A portion of everyone’s bill goes to balancing the grid.”

Growth in this revenue stream for energy storage could not come as a better time as revenues from primary reserve decline.

Primary reserve (FCR) and secondary reserve (aFRR) make up frequency control reserve services which ensure the grid’s balance between generation and consumption. In 2020, aFRR services paid over €100k/MW/year (US$111k) versus around €70k/MW/year for FCR.

Primary reserve stops extreme frequency drift when there is an imbalance event with a big and rapid-response (

Primergy has invested significant resources to minimize the physical footprint of the Gemini project where practicable to both preserve and protect local flora and fauna. The company has partnered with biologists to create the industry’s first Desert Tortoise Relocation Plan, which tracks, cares for and will safely reintroduce the protected species back into their natural habitat once construction is complete. Additionally, Primergy will implement responsible and efficient construction processes, such as using alternative site preparation methods and establishing narrow road corridors into the project site as well as building appropriately spaced, raised rows of solar modules to ensure nearly 80% of the land on site remains open to the sky.

“While the size, scale and innovative integration of solar PV coupled with battery storage makes Gemini one of the most complex clean energy projects ever developed, Gemini also sets new and timely benchmarks in sustainable infrastructure development,” explains Ty Daul, CEO of Primergy. “Through Gemini, Primergy has pioneered a holistic approach to responsible project development that considers complete ecosystem management, collaborative partnerships with local and community stakeholders and undertakes careful due diligence in supply chain and equipment selection. This ensures the company procures responsibly, minimizes environmental impact and delivers lasting community benefits across jobs, training and ongoing education in the benefits of large-scale clean energy infrastructure.”

Primergy’s Nevada portfolio alone exceeds 1,300 MW AC of solar and 3,330 MWh of battery energy storage systems under contract with NV Energy as well as multiple additional projects in the development phase.

Retailer Meijer has signed a renewable energy power purchase agreement (VPPA) with developer Duke Energy Sustainable Solutions, which states Meijer will purchase a portion of all energy generated by the project for the first 15 years of operation. The project broke ground in Navarro County, Texas on 1,800 acres of land and is expected to be completed by the end of the year.

“At Meijer, we are motivated to make an impact in the local communities we serve, and beyond, by doing our part and taking the necessary steps to reduce carbon emissions,” says Rick Keyes, Meijer’s president and CEO. “Meijer has made significant progress over the years to integrate sustainability into our daily operations. We’re committed to these ongoing efforts and a project like this brings us closer to our industry leading sustainability goals.”

Each year, the Pisgah Ridge Solar project will generate approximately 200,000 MWh of energy for the first year dedicated to Meijer. This clean energy will account for a reduction of more than 103,000 metric tons of CO2e from the retailer’s operations.

“Renewable energy assets like the Pisgah Ridge Solar project contribute to a cleaner, stronger economy and help create a more diverse energy infrastructure,” states Chris Fallon, president of Duke Energy Sustainable Solutions. “We’re pleased to be working with Meijer to create jobs, strengthen the local economy and generate cleaner energy, while also helping them address their carbon reduction goal.”
