EGAT had established the Renewable Energy Forecast Center (REFC) and the Demand Response Control Center (DRCC) (Figure 4.9) to support and increase the proportion of renewable energy used in electricity generation. These centers served as prototypes for renewable energy electricity production forecasting and demand response control in Thailand, using digital technology to modernize and strengthen Thai electrical system (Grid Modernization).

        The REFC was responsible for forecasting electricity production from renewable energy sources, including both wind and solar energy from Small Power Producers (SPP). These forecasts were used to plan electricity production in conjunction with other fuel-based power plants to manage fluctuations in electricity generated from renewable energy sources. The systems were also being developed to include Very Small Power Producers (VSPP) and Solar Rooftop installations.

        The DRCC functioned to respond electricity demand of power system especially during peak demand periods, as increasing power production during these peak periods may result in higher electricity tariff that will reflect to Ft price that eletricity users have to pay.

        REFC and DRCC were officially launched on August 17, 2023. These centers will be expanded to regional center level. REFC will also be established along EGAT high-voltage stations, starting from 11 inital centers, to support future integration of 8,000 MW renewable power in the future.
