Self-Consumption Solar Power to Receive RE100 Certification Starting in August

Residential and industrial solar power systems installed on rooftops will soon be able to obtain and sell renewable energy certificates. This change allows self-consumption solar power, which previously only helped reduce electricity bills, to generate new revenue through certificate trading.

The Ministry of Climate, Energy and Environment announced on July 21 that it will launch a pilot program for issuing and trading Renewable Energy Generation Certificates (REGO) for self-consumption renewable energy systems starting in August.

REGO certificates verify that electricity produced by solar and other self-consumption generation systems is 100% renewable. The government plans to issue these certificates after verifying the generation amount and production history through the Renewable Energy Monitoring System (REMS), allowing them to be sold on the RE100 certification trading platform to participating companies.

Until now, self-consumption solar power was primarily used to reduce electricity costs, but the new system will enable additional revenue through certificate trading.

The government expects that the introduction of this system will enhance the economic viability of self-consumption solar power, leading to increased installation and providing companies with a new means to meet their renewable energy usage requirements.

The pilot program will run from August to November. It will select corporations and individual businesses through a public recruitment process conducted by the Korea Energy Agency, with local governments participating as intermediaries to recruit privately owned generation facilities. The recruitment process began on July 20 and will continue until August 4.

Based on the results of the pilot program, the ministry plans to refine the system and fully implement the certificate issuance and trading program in 2027.

The Ministry of Climate, the Gyeonggi Province, and the Korea Energy Agency will sign a memorandum of understanding on July 22 at the Korea Energy Agency's Seoul headquarters to promote the pilot program. They will initially support the issuance and trading of certificates for 370 residential solar power systems, each with a capacity of 3 kW, provided by Gyeonggi Province.

Shim Jin-soo, Director of Renewable Energy Policy at the Ministry of Climate, stated, "The introduction of the self-consumption renewable energy certificate system will expand the deployment of related facilities and support companies in achieving their RE100 goals in various ways. We will gather diverse opinions during the pilot program to establish an effective system."
