Background

Previously, corporate renewable energy procurement via Power Purchase Agreements (PPAs) typically involved supplying electricity from a single generation site to a single demand site such as a factory or office. However, real-world needs have emerged for aggregating power from multiple small-scale solar plants or distributing electricity across multiple facilities and stores. This requires complex procedures such as detailed calculations of power usage and generation, submission of generation/demand plans to the Organization for Cross-regional Coordination of Transmission Operators (OCCTO), and monthly settlement processing—posing significant operational challenges.

Digital Grid has been using its Digital Grid Platform (DGP)* to automate these workflows. The newly acquired patent covers a technology that fully automates even more complex operations arising from connecting multiple generation and demand sites.

Key Technical Features of the Patent

This technology automates the following operations:

① A calculation logic that automatically allocates planned generation output (in 30-minute intervals) from each generation site according to the demand forecasts of each demand site.

② A system that automatically submits generation and demand plans to OCCTO based on the allocation results.

③ A program that corrects discrepancies between actual and planned generation using JEPX spot market prices and automatically generates monthly settlement statements for generators and consumers.
