RE100
RE100 defines renewable electricity as that generated from wind, solar, geothermal, sustainably sourced biomass (including biogas), and sustainable hydropower, requiring third-party certification for biomass and hydropower sustainability. EACs must correspond to the same electricity market as the supply being decarbonized, and corporate buyers must procure renewable electricity from sources commissioned or re-powered within the past 15 years.
For the latest requirements please visit the RE-100 website.
PRODUCTGROUPS: EECS, I-REC, RECS, UK REGO
Please note that the following labels marked with I-REC* are actually different productgroups and/or EAC certificate systems. They are placed under the I-REC section for your convenience to make it easier to trade. By selecting one of these labels, for example GEC-China, you are conveying that the intent is to buy/sell GEC - China certificates and not I-REC certificates.
GEC - CHINA
China's Green Electricity Certificates (GECs) verify the production and consumption of renewable electricity, with each certificate representing 1,000 kWh of green power. Eligible sources include wind, solar, biomass, geothermal, ocean energy, and hydropower. To ensure sustainability, third-party certification is required for biomass and hydropower, and each GEC can be traded only once to avoid double counting.
PRODUCTGROUPS: I-REC*
GEC - JAPAN
Japan's Green Electricity Certificates (GECs) authenticate the environmental value of renewable energy, enabling entities without direct access to renewable sources to claim green energy usage. Each GEC corresponds to a specific amount of electricity generated from renewable sources such as wind, solar, biomass, geothermal, ocean energy, and hydropower. To prevent double counting, GECs are issued exclusively for electricity not counted towards the Renewable Portfolio Standard (RPS) obligations.
PRODUCTGROUPS: I-REC*
NFC - JAPAN
Japan's Non-Fossil Certificates (NFCs) validate the environmental attributes of electricity generated from non-fossil sources, including renewables like solar, wind, biomass, geothermal, ocean energy, and hydropower, as well as non-renewables such as nuclear energy. Each NFC corresponds to 1 kWh of non-fossil-generated electricity. To prevent double counting, NFCs are issued exclusively for electricity not counted towards Renewable Portfolio Standard (RPS) obligations.
PRODUCTGROUPS: I-REC*
LGC – AUSTRALIA
Australia's Large-scale Generation Certificates (LGCs) are tradable under the Renewable Energy Target (RET) scheme, with each LGC representing 1 MWh of renewable electricity from accredited power stations like wind, solar, and hydro. LGCs are issued for electricity generated above a station's baseline and must be created by 31 December of the year following generation. The government sets the Renewable Power Percentage (RPP), requiring entities to surrender LGCs to meet RET obligations.
PRODUCTGROUPS: I-REC*
NZECS – NEW ZEALAND
Each certificate represents 1 megawatt-hour (MWh) of renewable electricity generated by registered production devices, including wind, solar, hydro, geothermal, and sustainably sourced biomass energy that meets specific efficiency or sustainability standards. The New Zealand Energy Certificate System (NZECS) follows a Production Year cycle from April 1 to March 31 of the next year.
PRODUCTGROUPS: I-REC*
TIGRs
Each TIGR represents 1 megawatt-hour (MWh) of renewable energy from registered projects, including wind, solar, biomass, geothermal, and hydropower, which must be grid-connected. Parallel registration in other tracking systems is generally prohibited, and projects receiving incentives that require relinquishing environmental attributes are ineligible. Certificates are stored in an Active Sub-account for transfer or retirement.
