Wind energy developers in Japan are expected to take advantage of the partial deregulation of the nation's electricity market, which will begin April 1. The Ministry of International Trade and Industry and the Fair Trade and Industry Commission have released their revised regulations, which will affect about 30% of the total power market. Under the revision, non-utility power producers can provide high voltage electricity to major commercial customers such as hospitals and companies. The voltage must be above 20,000 volts, with a minimum of 2000 kW of electricity sold. Independent power producers can rent space on the power lines owned by the nation's utility companies, just like private telecommunication firms now pay a fee to the national telecom company when sending information through its lines.
