Hokkaido Electric Power's Challenge in Renewable Energy - December 2001 Hokkaido Electric Power has focused on introducing renewable energy, developing an energy policy centered particularly on wind power generation. By 2001, it had set an annual power purchase target of 150,000 kilowatts, deepening cooperation with local power producers while advancing research and development to ensure stable energy supply. Specifically, it overcame the challenges of fluctuating wind power generation by introducing battery storage systems and improving the efficiency of the power network. Trends in the 2010s During the 2010s, Hokkaido Electric Power expanded its adoption of renewable energy, constructing new wind farms in Tomamae Town and Rumoi City. Its annual power purchase volume increased to approximately 500,000 kilowatts. Furthermore, the introduction of the Feed-in Tariff (FIT) system encouraged participation from local businesses. In collaboration with Hitachi, Ltd. and Sumitomo Ele
ctric Industries, Ltd., demonstration experiments were conducted on large-capacity storage batteries and power grid efficiency. This significantly reduced barriers to introducing wind power generation. Current Status in the 2020s
Entering the 2020s, Hokkaido Electric Power has set a target to achieve a 40% renewable energy ratio by 2030 and is actively implementing measures. Projects are underway, including the Ishikari Bay New Port Wind Farm (annual generation capacity of approximately 600,000 kilowatts) and an offshore wind power plan in Rumoi City. Research into next-generation energy technologies utilizing ammonia and hydrogen is also being pursued, forming a key pillar of the energy transition. Regarding CO2 reduction targets, the company aims to reduce emissions by approximately 2 million tons annually, contributing to sustainable development both regionally and nationally. Supplementary Information from Related Sources - Property Tax Revenue and Job Creation: According to a report by the Japan Wind Power Association (JWPA), Hokkaido accounts for over 30% of Japan's total wind power capacity. Property tax revenue from this sector exceeds ¥10 billion annually. This has stabilized the regional ec
onomy and created approximately 1,500 jobs. - Renewable Energy Penetration Rate: Statistics from the Ministry of Economy, Trade and Industry indicate Hokkaido's renewable energy penetration rate exceeded the national average at 35% (as of 2020). This demonstrates Hokkaido Electric Power's leading role in renewable energy adoption.
- Joint Research Outcomes: Presentations by Hitachi and Sumitomo Electric Industries indicate that transmission efficiency improvements and energy storage technologies support the stable supply of wind power. These technologies have been confirmed as applicable to other regions. Sources - Hokkaido Electric Power Co., Inc.
