Technical FAQs 4

How many battery storage projects will Stonepeak and CHC develop in Japan?

Stonepeak and CHC’s energy storage platform will develop five new battery storage projects in Japan. These projects have a combined capacity of 348 megawatts (MW). The deals were finalized under Japan’s Long-term Decarbonization Auction. These projects were selected as part of Japan’s latest long-term auction focused on low-carbon energy.

What are some examples of energy management projects in Japan?

Another example is the Kitakyushu Smart Community Project, which involves various forms of energy management including a 1 MW BESS system. Stonepeak and CHC’s energy storage platform will develop five new battery storage projects in Japan. These projects have a combined capacity

What is Japan's energy storage policy?

As policy, technology, and decarbonization goals converge, Japan is positioning energy storage as a critical link between its climate targets and energy reliability. Japan’s energy storage policy is anchored by the Ministry of Economy, Trade and Industry (METI), which outlined its ambitions in the 6th Strategic Energy Plan, adopted in 2021.

How do storage systems work in Japan?

Storage systems like BESS help keep power systems stable, especially when more electricity comes from solar and wind sources. Other projects in Japan include a municipal BESS project in Iida City, Nagano Prefecture. This small-scale system, with an installed capacity of 2 MW/4 MWh, is operated by a city-owned energy company.
