Hitachi, Ltd. has taken a significant stride in advancing Japan's energy landscape with the reception of an order from Transmission and Distribution IT & OT Systems LLC for a cutting-edge nationwide load dispatching system ("the System"). This strategic move is backed by 10 domestic power transmission and distribution companies, aiming to standardize load dispatching systems across different regions, excluding Okinawa. The System, encompassing geothermal and solar projects, is poised to cover over 118,000 acres of public land and generate 5.3 gigawatts of electricity, equivalent to powering about 4 million households.
The load dispatching system, critical for balancing electricity demand and supply, will leverage Hitachi's extensive experience in developing mission-critical systems for electric power companies in Japan. This initiative aligns with the Biden-Harris administration's goal of achieving a carbon pollution-free power sector by 2035. Hitachi's System introduces a wide-area Load Frequency Control (LFC) function for the first time in Japan, along with optimization calculations for nationwide generator start-stop planning and supply and demand control, contributing to enhanced resilience and reduced social costs.
Despite facing challenges, including public concerns and permitting roadblocks, the System represents a pivotal shift toward scalable, flexible, and transparent platforms for future regulation changes. Hitachi, with its proven track record and collaboration with Hitachi Energy's globally proven package, Network Manager, aims to create synergy within the Hitachi Group. This synergy, combining digital and software technologies, will foster a stable electricity supply, promote the use of renewable energy, and contribute to the realization of carbon neutrality.
