Since the Paris Agreement (COP21) took effect in 2016, measures to deal with the threat of climate change have been adopted worldwide. While an increase in renewable energy and changes in the power source composition are projected, connecting renewable energy directly to electric power systems destabilizes the voltage and frequency of the overall system. In Japan, moreover, signifi cant changes are taking place in the structure of the overall electric power system from generation to consumption due to power system reforms.
The Nippon Koei Group, which has carried out projects to develop new power sources and to meet demand for electric power in Japan and overseas, recognizes these changes and issues as new business opportunities, and is working on technological development in anticipation of future electric power energy policies.
Specific Measures
Decreases in third-party access costs and stable supplies, along with advances in network operating environments, have created a need for electricity monitoring and control systems to adapt to these changes.
TEPCO Power Grid, Inc. plans to consolidate the servers that had previously been installed at each load dispatching center and control station in a single location and install a next-generation monitoring and control system that will enable consistent monitoring and control from the power transmission system to the power distribution system.
As this system introduces the most advanced security technology, the decision was made to adopt it in the Tokyo area before the Tokyo Olympics and Paralympics. Preparations are under way with the aim of starting operation in April 2019.
The transformer gateway equipment that Nippon Koei will develop has the potential to be expanded globally as a product for future growth for the Nippon Koei Group, and Nippon Koei will team up with fi ve other companies including TEPCO Power Grid to develop business overseas. Based on advanced monitoring and control technology, tested and enhanced in the Japanese market, Nippon Koei will provide development, operation and maintenance technology in the deployment of power transmission and distribution facilities and contribute to high-quality infrastructure in Japan and overseas.
