概要
A key intention of the regulatory reform of transmission charge schemes on Japan's electric power market was to promote inter-regional competition between power suppliers by lowering long-distance transmission charges with a postage-stamp charge scheme. This can lead to extensive use of inter-regional links and cause congestion. Congestion segments the market into several regional markets, making the reform less successful. We developed a nine-region spatial equilibrium model to simulate the reform at the peak-load hour. We found the reform would lead to significant increases of inter-regional transmission and congestion at the link between the 50-Hz area and the 60-Hz area.
