Merchant market milestone for battery energy storage projects
Traditionally, battery energy storage system (BESS) and other similar projects have been either utility-owned, or underpinned by the existence of one or more long term offtake agreements. These agreements are a critical element for securing project financing, providing lenders with long-term financial assurances to support and validate the cash flow forecasts that form the basis of any debt financing. However, in May 2022, Norton Rose Fulbright represented North American Development Bank and Siemens Financial Services, Inc. on the closing of a US$78.2 million debt financing for 330 MWh of standalone BESS projects in California’s San Diego County. EnerSmart Storage is the developer, owner and operator of the projects. The deal marked a milestone in the sector as the first reported financing of fully-merchant BESS projects in the US, perhaps globally, meaning the projects are not supported by any long-term offtake agreements with utilities in place.
Merchant BESS projects operate in the wholesale market, generating all or most of their revenue from the merchant market. In layman terms, in order to maximize revenue from a merchant BESS project, an operator must buy electricity (and charge the BESS) during the lowest priced hours and sell during the highest priced hours each day on the relevant market. The revenue earned from the spread between sale and purchase price in the wholesale merchant market can then be stacked with other income streams such as ancillary services and capacity mechanisms.
Merchant market projects are complex, relying heavily on the use of innovative AI technology to inform the BESS to operate in the wholesale market at the optimum time(s) in order to minimise exposure to prices that can vary at intervals of anything from five minutes to an hourly basis. The complexity and uncertainty associated with modelling these revenues forms one of the key risks for lenders when considering financing a BESS project on a pure or majority merchant basis. How these risks are addressed contractually, who bears the legal risk of technology failure and whether there is any exclusion of liability under the legal framework will need to be carefully considered by the parties.
The advancement of use of AI technology plays an important role in making merchant market BESS projects more palatable for investors, and likewise investors are increasingly alive to the possibilities offered by well-designed, high quality, reliable AI programming. They will also rely heavily on market consultant reports, which are likely to be commissioned to forecast the wholesale market and the potential revenue return on any merchant BESS project in order to help mitigate the risks inherent in investing in projects without the guaranteed revenue streams of underlying offtake agreements. The use of AI, coupled with the expertise of a market-leading, well-respected consultancy, presents a new level of comfort for investors and is an exciting development for storage projects, meaning that perhaps such projects will be less challenging to finance in the future. Indeed, merchant markets are evolving rapidly on a global level, with many being intentionally designed to incorporate more BESS projects.
Although merchant BESS projects are not a new phenomenon, the debt financing of a standalone BESS project in a wholly merchant market marks a watershed moment. Whilst the EnerSmart projects are fully merchant, there has been an increasing trend emerging for BESS projects to be financed at least in part on a merchant basis. For example, in April of this year, Norton Rose Fulbright also represented Jupiter Power LLC on the closing of a US$177.8 million portfolio debt financing for six stand-alone BESS projects with 650 MWh capacity in Texas. Whilst not fully merchant, this project had only one firm offtake contract, with the majority of the projects’ revenue stream arising from the merchant market. As the energy storage market evolves and lenders become more comfortable with the risks of financing a merchant market BESS project and the AI software that ultimately underpins the optimization of these projects, we expect that there will be a significant increase in the number of fully merchant storage projects coming online.

The UK government has proposed the introduction of a cap and floor support mechanism for the long-duration electricity storage market and ensure the deployment of sufficient large-scale, to balance the overall system by developing appropriate policy to enable investment by 2024.
UK government cements energy storage's role as generation asset
In July 2022, the UK government entered the new Energy Security Bill into parliament, which amongst other things, defines the role of energy storage as a generation asset. The Energy Security Bill is designed to boost the UK’s energy security in light of recent market volatility. It includes 26 measures across three main areas: reforms to protect customers, leveraging private investment to develop domestic renewable generation, and ensuring the safety and resilience of the UK’s energy system. The Bill also aims to remove obstacles to battery energy storage and pumped hydro storage, by clarifying it as a distinct subset of electricity generation.
Germany finally gives energy storage its own legal definition
The German parliament announced that energy storage now has its own legal definition, which was adopted from Directive (EU) 2019/944 of June 5, 2019. The law on the Federal Requirements Plan, Energy Industry Act and Grid Expansion Acceleration Act have been adjusted to define energy storage as an asset where, “the final use of electrical energy is postponed to a later point in time than when it was generated…”. Prior to this amendment, an energy storage system was defined either as a generation or as a consumer asset based on whether it was discharging or charging. This new definition now clears any ambiguity and allows regulations to be created exclusively for energy storage.
Spanish govt approves public-private funding tool for green energy transition
Over the next two years, the Spanish government plans to invest €6.9 billion (US$7.7 billion) into renewables, green hydrogen and energy storage as part of its COVID-19 recovery plan (Strategic Project for the Recovery and Economic Transformation of Renewable Energies, Renewable Hydrogen and Storage). The government is hoping to attract a further €9.46 billion of private investments. According to the Spanish Cabinet, the quality of renewable resources will provide Spain with a competitive advantage in the development of renewable hydrogen, allowing it to become an international technology hub. €1.55 billion of state funding will be allocated to green hydrogen and a further €3.36 billion will be invested in job training, distributed power generation, and the use of renewable gases in transport. With Spain’s powerful industrial value chain in photovoltaic technology, it will probably continue to promote social innovation and consolidate renewable energy value chains.
North America
Inflation Reduction Act has already transformed energy storage industry thinking
The US’ Inflation Reduction Act facilities the introduction of the investment tax credit (ITC) subsidy for standalone energy storage. This means that, for the first time, energy storage doesn’t have to be paired directly onsite with solar PV generation. This means that battery storage projects can now be sited where they make the most sense. It is expected that the IRA supportive policies will likely double demand for energy storage in the US by 2030.
Department of Energy confirms US$504 million loan to 300 GWh Utah hydrogen energy storage hub
The US Department of Energy plans to lend US$504.4 million to developers working on one of the world’s largest green hydrogen projects in Utah. This project will involve Mitsubishi Power Americas and Magnum Development and aims to employ 220 MW of wind and solar-powered electrolysers, and store the hydrogen in two natural salt caverns, each capable of holding 150 GW-hours of energy with the facility. It will also supply hydrogen to the Intermountain Power Agency's IPP Renewed Project, a power plant in southwest Utah capable of burning 30 percent hydrogen from 2025. As of early September 2022, the storage hub has secured all major contracts including engineer, procurement and construction contractors, major equipment suppliers, and operations and maintenance providers. Haddington Ventures, this projects equity sponsor, is aiming to raise US$650 million for the project.
The California Public Utilities Commission (CPUC) has approved nine battery energy storage system (BESS) facilities proposed by PG&E, in response to an order to procure 11.5 GW of clean energy capacity under the CPUC’s internal resource planning process. The nine BESS projects will amount to a total of 1.6 GW / 6.4 GW and are expected to be operational by June 2024. The CPUC will also partially contribute toward Summer Reliability Targets, a requirement that was enacted in December 2021, following extreme weather events that placed a strain on the grid.
How would a Clean Electricity Standard decarbonize the grid?
In this podcast, Jesse Jenkins, an energy-modelling expert at Princeton, discusses the mechanics of the proposed US national clean electricity standard, as well as details of its inclusion in Biden’s proposed US$3.5 trillion infrastructure plan.
The US Department of Energy announced in July 2021 its intention to reducing the cost of grid-scale, long duration energy storage by 90 percent within the decade. This target will support increased clean energy generation capacity and support the US goal of 100 percent clean energy by 2035.

Chile passes major energy storage bill
The Senate of Chile unanimously passed legislation on 20 October 2022 which will incentivize the deployment of energy storage technology. This bill seeks to utilize energy storage to overcome grid congestion, as 748 GWh of renewable energy has been curtailed already in 2022 and the country currently only has 64 MW of utility-scale battery storage operational. Energy storage systems will be able to receive income from dispatching their energy in the country’s National Electric System market. The conversion of a coal plant into 560 MW of molten salt-based energy storage has additionally been proposed, and Canadian Solar has won a tender to deploy solar-plus-storage with 1 GWh of battery storage.
