ENECHANGE Ltd. (Head Office: Chuo-ku, Tokyo; CEO: Tomoya Maruoka) is pleased to announce that the Japan Energy Fund, an overseas-specific decarbonized tech fund in which ENECHANGE participates, has invested in Equilibrium Energy through Japan Energy Capital as of March 7, 2025.

Headquartered in San Francisco, CA, Equilibrium is building the operating system for the next-generation of power companies. This $28 million funding round was led by GS Energy. Existing investors DCVC and Valo Ventures also participated.

Background

As the world seeks to decarbonize and bring additional renewable generation resources online, the intermittent nature of these resources is adding volatility on the grid. This trend is further underpinned by the growth in electricity demand from data centers, electric vehicles, and other sources, as well as the increasing frequency of extreme weather events that add further stress to the grid.

Asset developers have responded with additional buildout of battery capacity to capitalize on volatile prices and new balancing/ancillary services schemes – Texas and California both saw a over 4x and 2x growth respectively in the level of commercially operational battery energy storage capacity from 2022-2024*1.  Japan is also expected to see increasing deployments of grid-storage batteries, with a forecasted 14-23GWh by 2030*2.

As asset owners seek to maximize revenues in the participation of various grid and wholesale market schemes, the ability to refine trading strategies over time to maximize performance will be an essential differentiator amongst market participants. With the complex nature of power trading, including a wide variety of unique and evolving market participation rules as well as a risk of financial losses, it is a significantly difficult task to manage.

This is where so-called “optimizers” step in. Optimizers manage batteries and other assets on behalf of their owners, leveraging their own proprietary technology and strategies to maximize revenues. Depending on the precise arrangement between the optimizer and owner, owners can determine how much risk they are willing to take on future market revenues. In some cases, owners can largely de-risk the investment via a fixed fee payment from the optimizer under a tolling agreement, allowing the asset to become bankable and eligible for better debt financing terms and the optimizer to benefit from its performance premium. 

With the increasing availability of data and advances in artificial intelligence, optimizers have new opportunities to gain advantages in developing and executing winning trading strategies.

About Equilibrium Energy’s technology breakthroughs

Equilibrium Energy seeks to be a next-generation power company, operating at the intersection of technology and trading in the energy markets.

Equilibrium’s core advantage as an optimizer is in its software platform, which allows for rapid, data-driven development of trading strategies. Utilizing a wide array of market and asset data, the platform leverages artificial intelligence for forecasting and optimization of its trading models.

Equilibrium has contracted with battery owners as an optimizer and has signed multiple tolling agreements. In June 2024, Equilibrium was recognized as the top performing 1-hour battery operator in ERCOT*3.

With this investment round, Equilibrium will continue to grow its portfolio of assets under management via the signing of new tolling agreements from its 6GW pipeline.

Comment from Tomoya Maruoka, CEO and Representative Director of ENECHANGE Ltd.

The global growth of grid-scale battery capacity is a critical component in addressing the broader trends of increasing electricity demand and rising renewable energy generation. Optimizers will naturally find synergies with battery developers, and technology-first, data-driven companies like Equilibrium Energy—focused on building scalable platforms supported by deep industry expertise—are well-positioned for success. We are thrilled to participate in this investment round and support Equilibrium’s growth, as innovative solutions like theirs will be essential for the future of Japan’s energy sector.
