Gore Street Capital Appointed Joint Manager of Japan’s first Energy Storage Fund

We are pleased to announce that Gore Street Capital and ITOCHU Corporation have been selected by the Tokyo Metropolitan Government (TMG) to launch Japan's first fund dedicated to grid-scale energy storage systems.

The two firms have been jointly selected as the managers of TMG's energy creation and energy storage promotion fund following a competitive process held in April 2023. The pair will launch a joint venture to manage the public-private partnership fund, to which TMG will contribute ¥2bn (£10.6m) in funds by the end of fiscal year 2023. Additional funding will be raised from the private sector, including from ITOCHU.

The fund will be targeted at projects in the Kanto region of Japan. TMG intends for the energy storage assets to support its efforts to expand renewable electricity usage to 50% by 2030. ITOCHU is already developing several grid storage battery projects in Japan, with a cumulative total of more than 100 MWh of assets under development.

Alex O’Cinneide, CEO of Gore Street Capital, said: “We are proud to have been selected as the joint manager of Japan’s first dedicated energy storage fund in partnership with ITOCHU. 

“Gore Street Capital was one of the first to act in Great Britain’s energy storage market back in 2016 and, in its capacity as investment manager of the internationally diversified Gore Street Energy Storage Fund (LSE: GSF), has a proven track record of acquiring and managing a large portfolio of energy storage assets across multiple OECD jurisdictions.

“We have developed a specialist platform offering the full range of technical expertise needed to successfully monetise energy storage assets throughout their lifetime, from acquisition and construction, asset management and commercialisation all the way through to decommissioning and recycling.

“We look forward to bringing this experience to Japan, alongside our partners at ITOCHU, to deploy the energy storage capacity needed to accelerate the country’s clean energy transition to a low-carbon and sustainable future.”

The new fund will aim to establish a new green financing model for investments in Japan’s nascent utility-scale energy storage sector. GSC and ITOCHU will jointly manage the investment and technical decisions taken by the fund, creating the foundations for the country’s future deployment of grid-level energy storage assets.

Several revenue streams are already in place nationally to support new energy storage, including access to Japan Electric Power Exchange (JEPX) – one of the most mature wholesale energy markets in the Asia–Pacific region – and grid balancing services.

New ancillary services are expected to launch in 2024 alongside long-term decarbonised power supply auctions that will allow battery energy storage of three hours duration to participate and secure subsidies over a 20-year period.

Suminori Arima, chief investment officer at Gore Street Capital, said: “We are highly experienced in entering new markets as a first mover to help establish energy storage as crucial technology of the energy transition. The market conditions in Japan are poised to offer significant opportunities for those willing to take them.

“Through this collaboration with ITOCHU, we are excited to build on our experience and help shape the future of the Japanese energy storage sector.”
