Energy storage and the EU Green Deal
In the run-up to COP26 in Glasgow, momentum is strengthening to accelerate the decarbonisation of the global economy, and in particular its energy and transport systems. Energy storage and batteries will be important in this transition.
From an energy systems perspective, in the EU unfavourable conditions or barriers for the development and financing of energy storage projects often still prevail. Reform is underway however. As part of the EU Green Deal, the European Commission has begun a comprehensive review of relevant EU legislation to determine to what extent amendment or additional legislation is necessary to make the EU carbon neutral by 2050. These changes are expected to create a true level playing field for storage technologies.
To support the EU Green Deal objectives, the EU has adopted a €1.8 trillion package of funding options. Depending on factors including maturity of the storage technology and the specific system services it can provide, storage may be eligible for funding, strengthening the business case for its deployment in the EU.
In our experience, funding models for energy storage in the EU are diverse, depending not only on technology and risk appetite, but also on local electricity market structures. Whilst project finance is still relatively rare in Europe, colleagues in the US have recently assisted in the financial close of a portfolio of six storage projects (further information available here).
In relation to the decarbonisation of transport systems, battery electric vehicles will play a strategic role. In Europe, there is support for increased European battery manufacturing capacity, with the European Investment Bank increasing its financing for the sector in 2020 to €1bn. However, the European Commission has made clear that this expansion is not to be undertaken at any cost. As a result of the battery sector’s strategic importance, EU policy is now focused on creating a harmonised framework covering the entire battery life-cycle. In its proposal for a Regulation on batteries and waste batteries, the European Commission proposes to strengthen the sustainability of supply chains and improve the recycling of industrial, automotive, electric vehicle and portable batteries placed on the market in the EU.

Corporate funding in battery storage in 2020 was up by 136 percent compared to 2019, Mercom says
Mercom found that while corporate funding rose significantly with US$6.6bn raised across 54 deals in 2020 compared with US$2.8bn in 42 deals in 2019, venture capital funding into battery storage dropped slightly, totaling US$1.5bn in 32 deals last year, compared to US$1.7bn from the same number of deals in 2019. The report names Swedish lithium-ion battery design and manufacturing startup Northvolt as the top recipient of venture capital funding globally. US company Quantum Scape and UK energy storage developer and system integrator Zenobe Energy also feature in the top five funding recipients. Debt and public market financing for battery storage companies was reported to have risen significantly from US$1.1bn across ten deals in 2019 to US$5 bn in 22 deals in 2020. The full Mercom report is available here.
Battery pack prices reported below US$100/kWh for first time
According to research by BloombergNEF, the cost of lithium-ion battery packs has fallen close to 90 percent and average prices are forecast to be close to US$100/kWh by 2023. The fall is attributed to rising order sizes and battery electric vehicle sales growth, leading to economies of scale for battery manufacturers, and to the falling cost of cathode materials since 2018, improving profit margins for developers. BloombergNEF believes that even a rebound in the cost of raw materials would only delay the decline of pack prices given the industry’s increasing resilience to cost fluctuations, due to consolidation up the value chain.

Demonstrating significant industry interest, operators bid 1,327 MW, six times more than the required 230 MW, at a third of the auction base price. The pilot project will see batteries provide to and stabilize the grid with ultra-rapid frequency reserve for the first time, offsetting the reduction in traditional generation and anticipating significant expansion in intermittent renewable sources of electricity.
The stretch of river holding Spain’s pumped hydro future
The Mont-Negre (3.3 GW) and Gironés & Raïmats (3.1 GW) projects are reported to be competing to build and operate pumped hydro plants on the Riba-roja reservoir in Spain, but commentators suggest only one project may proceed. ENTSO-E data released in a quarterly report on electricity markets issued by the European Commission in 2020 is reported to have shown that Spain ranks only behind Italy, Germany and Austria in terms of operational, planned and announced pumped hydro capacity Europe.
Google to test data center battery backup that also serves the grid
As part of its aim to meet round-the-clock electricity demand with carbon-free sources by 2030, Google has announced that it will install a 3 MW, 2-hour-duration backup battery at its data center in Belgium. Google’s batteries would provide frequency regulation to the grid. Models estimate data centers account for approximately 1 percent of global electricity use and are currently supplied by 20 GW of diesel generation. If demand were to grow for cleaner backup generation for data centers, this could accelerate the uptake of storage by providing an additional revenue steam.

McKinsey: Continuous fall in battery prices is enabling the rapid rise of renewable energy
With many of the world’s leaders putting policies in place to support decarbonization and technology costs falling, McKinsey’s Global Energy Perspective 2021 has predicted that renewable energy will make up around 55 percent of global power generation by 2035, enabled by a continuous fall in battery prices. Renewable energy combined with battery storage is becoming increasingly cost-competitive with fossil fuels. The report indicates that there will still be a role for some fossil fuel assets, such as gas peaker plants in the sector, and other technologies, notably hydrogen, will have important roles to play. The report also noted a role for hydrogen that could be used to decarbonize hard-to-abate sectors such as industrial processing and double up as a long-duration storage solution in the power sector. The full McKinsey report is available here.
Pumped hydro moves to retain storage market leadership
The International Hydropower Association and the U.S. Department of Energy announced an alliance of 11 national governments and more than 60 organizations to speed up the development and deployment of pumped hydro projects globally. New pumped hydro projects typically involve significant expenditure over a number of years and a lack of suitable locations has made new projects challenging. The increase in cheaper renewable power has also impacted the economics of pumped hydro, which relies on price arbitrage. Total project costs range between US$106 and US$200/kWh, compared to between US$393 and US$581 for lithium-ion batteries, World Bank figures show. However, despite this price advantage, pumped hydro projects are not progressing. The International Forum on Pumped Storage Hydropower will focus on developing policy and market frameworks, maintaining environmental sustainability standards, and demonstrating and improving the value of projects. A first step has been the development of a pumped storage valuation guidebook that helps developers, owners and operators assess the value of hydropower projects.
LevelTen Energy launches PPA-style contract for energy storage projects
Renewable Energy procurement advisor, LevelTen Energy, is reported to have developed a RE-Store Energy Agreement, designed for utility-scale storage projects. The contract means that buyers are paid the difference between highest and lowest hourly energy prices each day in the wholesale market, while the storage owner receives a fixed revenue stream. The buyers do not take on the operational risk that is associated with other utility-scale storage projects, and the storage owner does not need to sit alongside an energy generation system and can use stable revenues to raise debt finance. Further details available here.

South Africa’s 2 GW Risk Mitigation tender and what it means for energy storage, renewables and gas
South Africa’s Ministry of Mineral Resources and Energy launched a risk mitigation procurement program for 2 GW of energy capacity. Independent power producers were invited to prepare bids for renewable energy projects paired with energy storage or natural gas projects with an installed capacity of between 50 MW and 450 MW for 20-year power purchase agreements. Winning projects will need to be dispatchable under terms defined by the tender: the main requirement being that they can dispatch power to the grid as needed between the hours of 05:00 and 21:30. The tender was closed off to coal and diesel plants. Given the technical criteria, it is expected that storage will play a role. The deadline for bid submissions has passed. A list of bidders is available here.
Asia Pacific
The Asia-Pacific region will continue to be the world’s leading center of lithium-ion cell manufacturing for the next decade according to new analysis by research firm Wood Mackenzie. Battery price reductions, the biggest factor in system costs savings in 2020, together with a growing focus on hardware components that make up large-scale energy storage systems, will drive a 30 percent drop in front-of-meter battery storage in key markets China, Australia and South Korea.
China’s energy storage deployments for first nine months of 2020 up 157 percent year-on-year
China deployed 533.3 MW of new electrochemical energy storage projects in the first three quarters of 2020, an increase of 157 percent on the same period in 2019 according to work conducted by in-house research group China Energy Storage Alliance. This brings the total installed energy storage capacity to 33.1 GWh, a significant portion of the global total of 186.1 GWh. These figures include all forms of energy storage including pumped hydro, which still accounts for more than 90 percent of installed capacity.
NSW’s ‘urgent’ electricity infrastructure bill includes 2 GW of long-duration energy storage
Policymakers for New South Wales in Australia have been debating a bill to co-ordinate investment in the state’s electricity infrastructure that includes 2 GW of long-duration energy storage and A$50m (US$36.71m) support for green hydrogen over ten years.

2020: A key year for the future of energy storage in Europe
The Energy System Integration Strategy, the Hydrogen Strategy and the Renovation Wave were released in 2020, supporting the growth of energy storage, including power-to-x, thermal storage and residential storage solutions. Together with this strategic framework, a number of financial and fiscal initiatives have been introduced to address the barriers faced by energy storage stakeholders. Notably the Just Transition Fund, which aims to help mobilize €150bn between 2021 and 2027, was expanded to support energy storage technologies.
EU seeks competitive edge from green batteries
The EU is introducing new regulations that will create a sustainable battery market by forcing manufacturers to use recycled materials and to reduce emissions. From 2024, electric car and industrial battery manufacturers will have to declare the battery’s carbon footprint and, from 2027, comply with an emissions limit. From 2027, there will also be an obligation to disclose the content of recycled raw materials, followed by requirements to use a minimum share of recycled cobalt, lithium, nickel and lead from 2030. It is hoped that the regulatory framework will give the EU’s battery production a competitive edge in its ‘green’ manufacturing. There are concerns however that the proposals will add complexity and lead to over-regulation.
Germany: Growth in home and industrial sectors but large-scale battery storage slowed down in 2019
Research by academics at RWTH Aachen University found that in 2019, Germany saw a slowdown in the large-scale battery storage sector with nine projects coming online, compared with 22 in the previous year. Revenues from frequency containment reserve (FCR) have been falling as battery storage in Germany has increased and FCR auctions have become more competitive. More positively, the German network regulator Bundesnetzagentur approved proposals by grid companies to create so-called ‘virtual transmission lines,’ in an undertaking called GridBooster. This should include two projects of 100 MW / 100 MWh each and another of 250 MW / 250 MWh providing redundancy and spare capacity to large transmission lines. There has also been continued growth of residential battery storage, with 250 MW / 490 MWh added during 2019.
Classifying storage as generation in Great Britain must be a stopgap
Ofgem (Great Britain’s energy regulator) has pushed ahead with classifying battery storage as a subset of generation, to the disappointment of some in the sector. The change was in part motivated by the double charging of storage which, without formal definition, was treated as both demand and generation. The Renewable Energy Association has called for this definition to be a preliminary measure, until further parliamentary time can be dedicated to defining how battery storage fits into the legislative framework.
As part of the continued development of Dynamic Containment in Great Britain, National Grid ESO is to allow participants to stack their revenue streams, with batteries able to tender for bids in both the BM and Dynamic Containment during the same periods. Dynamic Containment was widely welcomed in 2020, as not only a significant tool for National Grid ESO but also for providing a strong return for participants, offering two to three times the price of other frequency response services. Guidance from NGESO can be found here.
Lithuania plans to invest €100m to install four 50 MW batteries with at least 200 MWh of storage capacity. As well as providing backup to the grid (currently interconnected with Russia), the batteries will support the planned expansion of renewable power generation, which is projected to reach 4 GW in 2030 in Lithuania.
Royal decree confirmed that storage will be integrated in the next Spanish renewable auctions
Spain is reported to be looking to install 60 GW of renewables by 2030. A royal decree has been approved by the country’s Council of Ministers for the pay-as-bid auctions that will allow hybridization between technologies and be compatible with energy storage. Alongside this framework, the Council of Ministers have also approved a decarbonization strategy whereby the country will reduce 90 percent of greenhouse gas emissions by 2050, and create carbon sinks through reforestation to absorb the remaining 10 percent.
North America
Energy storage hits record level in third quarter
A record 476 MW of storage was deployed in the third quarter of 2020. This marked a 240 percent increase over the previous high. Although the increases were across the board, the biggest rise was attributed to front-of-the-meter (FTM) storage procurements. Massive systems deployed in California drove the record growth. Despite the economic downturn and COVID-19 related effects, the US Energy Storage Association believes that energy storage is poised to continue this trajectory with unprecedented increases in the coming months.
US Department of Energy publishes its ‘first comprehensive energy storage strategy’
The US Department of Energy (DOE) has published the Energy Storage Grand Challenge Roadmap, its first comprehensive strategy on energy storage. The strategy includes cost and performance targets to be met with a goal to establish the US as a leader in energy storage. The DOE will establish five “tracks” to implement its strategy: a Technology Development Track, a Manufacturing and Supply Chain Track, a Technology Transition Track, a Policy and Valuation Track and a Workforce Development Track.
The final report from the California Public Utilities Commission (CPUC), the California Energy Commission and state grid operator CAISO about California’s rolling blackouts in August revealed that the heat waves caused a supply-demand imbalance. This imbalance was not corrected due to problems with California’s resource adequacy program and market practices for ensuring adequate grid capacity. In order to mitigate these issues in the future, CPUC has ordered utilities to speed up their build-out of energy storage and solar-battery capacity.
Alberta’s fast frequency response pilot is ‘a step in right direction’, Energy Storage Canada says
Alberta Electric System Operator (AESO) is expected to implement a fast frequency response (FFR) pilot in late 2021 for 12 to 18 months. FFR will require providers to respond within 0.2 seconds when the grid system’s frequency hits 59.5 Hz to bring it back up to 60 Hz and AESO is targeting any new technology that can meet these requirements. Energy Storage Canada, a trade association, believes this pilot is an opportunity for energy storage resources in the province; however, the tariff treatment of energy storage resources is still a hurdle.
As battery storage developers look for contracted revenue streams and for ways to manage commercial risks associated with their projects, commodity hedges and related derivatives provide unique opportunities to accomplish their goals. Energy storage hedges may become more common as capital costs for battery storage assets decrease, especially if the US Congress enacts a tax credit for standalone energy storage.

Puerto Rico Electric Power Authority (PREPA) will issue six solar and storage procurements, totaling 3.75 GW of solar and 1.5 GW of four-hour storage, within the next 30 months. The regulator has set a target to release the first procurement as early as possible this year to secure 1,000 MW of solar and 500 MW of storage. A study by PREPA concludes that Puerto Rico’s grid can handle only 650 MW utility-scale renewable generation, including existing renewables. That value could increase as a result of system upgrades and energy storage systems expected to be incorporated in the near future.
The Chilean National Energy Commission (CNE) has issued definitive terms to conduct an auction for 2,310 GWh of renewable energy capacity and energy storage in May 2021. Power generators will need to start supplying energy and capacity in 2026 under 15-year power purchase agreements. The bidding terms aim to reduce market risks, encourage energy suppliers' participation, achieve competitive prices that benefit regulated customers and provide more access to different types of energy projects, including storage.
