Power Supply
Power Supply
Japan’s electricity wholesale supply system was established in 1995. This allowed independent power producers (IPPs) to participate in power supply, which until then had been the exclusive domain of electricity utility companies. Under the new system, Nippon Steel has entered the electricity wholesale supply business.
Following the revision of the Electricity Utilities Industry Law in March 2000, retail supply of electricity to major users was deregulated. In this regard, Nippon Steel notified the government agency concerned in January 2001 that it had become a "Power Producer and Supplier (PPS)" and started operations in the electricity retail supply business.
Business Development in the Wholesale Supply
- Utilization of power-generation technologies fostered in steelworks in-plant power generation
- Nearly 87% of total electricity consumption by in-plant power generation equipment
(refer to page for the power supply)
- Nearly 87% of total electricity consumption by in-plant power generation equipment
- Utilization of steelworks infrastructure such as land, ports/harbors and raw materials yards
