How Japan trialed blockchain to trade solar energy

A Japanese utility has trialed a blockchain platform for residents to sell excess solar power.

The software allows producers of solar energy to track market prices, and sell at their unused power at competitive rates. Others who don’t produce their own renewable energy would be able to buy this at market rates.

The trial was run at a research lab in Osaka, under a partnership between Kansai Electric Power Company (KEPCO), the second-largest utility in Japan, and Australian company Power Ledger.

The project is among a host of others that are being run in Asia, with households and businesses able to buy and sell renewable energy at more affordable rates on a digital marketplace.
