RE Bridge: Revolutionizing Corporate PPAs in Renewable Energy

In July 2023, Digital Grid Inc., based in Minato, Tokyo, launched its innovative matching platform, RE Bridge®, which promotes corporate Power Purchase Agreements (PPAs). By May 12, 2025, the platform exhibited significant growth, boasting a total generation capacity exceeding 1GW and listing over 300 power plants. This development illustrates an increasing demand for transparency within the corporate PPA market and highlights the need for robust matching between electricity producers and consumers.

The Rise in Listings on RE Bridge®

When comparing data from the last auction held in December 2024, RE Bridge® has seen substantial increases in both capacity and the number of participating power plants. The previous capacity stood at 339MW with 158 power plants listed, whereas recent figures show a growth to 1093MW and 312 plants. Such growth underscores the rising need for clarity in the corporate PPA landscape among both power producers wanting to establish buyer relationships and consumers seeking stable access to renewable energy.

What is RE Bridge®?

RE Bridge® is designed specifically as a renewable energy matching platform centered around corporate PPAs. It connects electricity producers, eager to secure buyers, with consumers desiring long-term access to additional renewable energy sources. The platform provides comprehensive support from project identification to contract finalization, ensuring that once a deal is made, Digital Grid manages ongoing supply-demand operations. Furthermore, participating companies will receive insights into proposed PPA rates, without disclosing producers' identities, enabling them to better understand the market dynamics affecting their decisions.

Introduction to GPA®

Digital Grid has introduced another innovative scheme known as GPA® (Green Purchase Agreement). This comprehensive trading system allows consumers to directly purchase environmental values (such as non-FIT non-fossil certificates) generated from additional renewable energy, straight from businesses certified under the Feed-in Premium (FIP) scheme. GPA® minimizes price fluctuations for environmental values, enhancing stability for consumers.

Benefits for Consumers and FIP-Certified Businesses

For consumers, this structure means that they do not need to switch their existing retail electricity contracts and can remain flexible in terms of procurement timelines and quantities. Additionally, long-term contracts with renewable energy producers ensure secure access to essential non-FIT environmental certificates.

Conversely, businesses certified under the FIP system can enjoy stabilized revenue streams, as the GPA® structure offers a virtual fixed selling price, allowing for reliable income regardless of market volatility. Moreover, complicated management tasks around forecasting and settlements are centralized, dramatically simplifying operational demands for producers.
