Next Energy & Resources Co Ltd (Komagane City, Nagano Prefecture) announced July 25, 2019, that it has formed a business partnership with Contemporary Amperex Technology Co Ltd (CATL, a China-based major battery manufacturer) on the development and sale of storage batteries.
They will develop a stationary storage battery supporting the "third-party ownership (TPO) model" of solar power generation, aiming to commercialize it in a year.
CATL was established in 2011 and develops, manufactures and sells storage batteries for electric vehicles (EVs) and stationary storage batteries. It has partnerships with major automakers in various countries and has one of the world's best track records in terms of the sales of automotive rechargeable batteries. CATL aims to expand its business also in the market for stationary batteries and considers Japan as a strategically important region.
According to Next Energy & Resources, price-competitive storage batteries are crucial for promoting the use of solar power generation (PV) systems as decentralized energy systems. By combining PV systems and storage batteries, it becomes possible to provide supply-demand adjustment services and contribute to solving problems related to the adjusting power for power grids, the company said.
In Japan, self-consumption-type PV systems that do not use the feed-in tariff (FIT) scheme are being increasingly used because their price competitiveness is improving. Especially, the TPO model, with which utility customers can introduce PV systems without initial investment, is drawing attention. Next Energy & Resources considers that, when the price competitiveness of storage batteries improves, storage batteries will be employed for the TPO model as standard features.
Currently, the introduction cost of a storage battery is ¥2 million to 2.5 million (approx US$18,323-22,911). Next Energy & Resources aims to reduce the introduction cost by 75% in three to five years by promoting the TPO model business including storage batteries.
