Financial services team Orix, utility Kansai Electric construct 113MWh battery storage system in western Japan

• A joint venture (JV) in Japan between monetary services team Orix and regional utility company Kansai Electric (KEPCO) will develop and operate a large-scale battery storage system.

Orix said last week that the JV is preparing to start building this August of the 48MW/113MWh battery energy storage system (BESS) project, to be in operation by 2024.

The announcement comes ahead of guideline adjustments in the Electricity Business Act which regulates Japan's electricity market, whereby grid-connected BESS assets of 10MW or higher result will be eligible from next year to sign up as generation sources for involvement in trading possibilities like day-ahead markets.

In January, Japanese information electrical outlet Nikkei reported that numerous big business entities are preparing a play for market share in the battery storage area as it emerges.

To day, the nation has among the biggest residential battery markets for backup power and solar self-consumption worldwide, and also commercial and industrial (C&I) systems for peak shaving are progressively prominent as well.

Nonetheless, interest in large-scale batteries has not actually advanced beyond the pilot phase, other than in the northern island area of Hokkaido, where an extra of renewable energy installations suggests solar PV and also wind project designers have to include storage to their projects under the policies of that region's monopoly utility Hokkaido Electric Power.

Reforms to the market by means of the Electricity Business Act can change this landscape significantly. Japan has likewise increased its target for adding renewables to its energy mix to be 36%-38% of power supply by 2030. This still drags lots of various other nations' targets yet is a significant rise from a previous target of 22%-24%, while longer term, Japan has dedicated to web absolutely no emissions by 2050.

Nikkei noted in its January short article that Orix owns a 20% stake in United States geothermal power manufacturer Ormat Technologies. Ormat has actually just recently expanded right into other energy technologies including energy storage. There was no reference of the US company in Orix's declaration recently consisting of whether it would certainly offer tools or services to the JV's project.

The Orix-KEPCO 50:50 JV is called Kinokawa Energy Storage. KEPCO is among Japan's 10 significant utility companies. Historically, these utilities have been in charge of everything from generation and supply to transmission and also distribution of electricity.

As part of continuous reforms to liberalise the energy market, these local syndicates have been broken up, or unbundled-- KEPCO for example is now separate from Kansai Transmission & Distribution, which took control of the T&D part of its business in 2020.

Kinokawa Energy Storage's 48MW BESS will be released at a Kansai Transmission & Distribution substation Wakayama, the southerly prefecture of the Kansai region which likewise consists of the significant cities of Osaka and Kobe.

The BESS will absorb power from the grid when there is an excess, such as sometimes of abundant solar or wind generation. It will store the electricity and afterwards output to the grid at peak times when it is most required.

KEPCO will certainly run the facility while Orix will supervise of upkeep and asset management.

The pair claimed that they hoped their JV would be able to contribute to addressing concerns such as the scarcity of electricity supply for use on the grid and the ongoing curtailment of variable renewable resource assets.

Orix has a lot of experience in the renewables field, having actually invested in, owned or operated assets in countries including the US, China as well as Latin America. It is likewise a financier in Greenko, the Indian renewable resource designer which is marketing dispatchable wind as well as solar paired with pumped hydro, and also Orix additionally set up a UK office in 2018.
