Non-fossil certificates: key questions
What are non-fossil certificates (非化石証書)?
Certificates that carry the non-fossil value of electricity from renewable, nuclear and other non-fossil plants, traded separately from the power itself, mainly through JEPX auctions. Retailers with annual sales of 500 million kWh or more buy them to meet the 44% non-fossil target for FY2030 under the Act on Sophisticated Methods of Energy Supply Structures (エネルギー供給構造高度化法); companies buy them to back renewable-electricity claims.
What is the difference between FIT and non-FIT certificates?
FIT certificates come from generation paid under the feed-in tariff and are sold by multi-price auction in the renewable value trading market (再エネ価値取引市場), where companies and intermediaries can buy as well as retailers. Non-FIT certificates come from other non-fossil plants, either with a renewable designation (再エネ指定) or without one (指定なし, e.g. nuclear), and are sold by single-price auction in the obligation market (高度化法義務達成市場), where only retailers can buy.
How often are the auctions held?
JEPX runs four auction rounds per fiscal year, from late August to May, and each round covers FIT, non-FIT renewable and non-FIT certificates. Every result since August 2018 is listed in the table on this page. For how certificates fit with power purchase agreements, see the Japan power market guide.
