Tokyo Electric Power Company发表评论(0)编辑词条

Tokyo Electric Power Company, Inc. (東京電力株式会社 Tōkyō Denryoku Kabushiki-gaisha, TYO: 9501), also known as Toden (東電 Tōden) or TEPCO, is a Japanese electric utility servicing Japan's Kantō region, Yamanashi Prefecture, and the eastern portion of Shizuoka Prefecture. This area includes Tokyo. Its headquarters are located in Uchisaiwaicho, Chiyoda, Tokyo, and international branch offices exist in Washington, D.C., and London. It is a founding member of strategic consortiums related to energy innovation and research; such as JINED,INCJ and MAI.

In 2007, TEPCO was forced to shut the Kashiwazaki-Kariwa Nuclear Power Plant after the Niigata-Chuetsu-Oki Earthquake. That year it posted its first loss in 28 years. Corporate losses continued until the plant reopened in 2009.Following the March 2011 Tōhoku earthquake and tsunami, its power plant at Fukushima Daiichi was the site of a continuing nuclear disaster, one of the world's most serious. TEPCO could face ¥2 trillion ($23.6 billion) in special losses in the current business year to March 2012, and the Japanese government plans to put TEPCO under effective state control to guarantee compensation payments to the people affected by the accident.The Fukushima disaster displaced 50,000 households in the evacuation zone because of leaks of radioactive materials into the air, soil and sea.

In July 2012 TEPCO received ¥1 trillion from the Japanese government. TEPCO's management subsequently made a proposal to its shareholders for the company to be part-nationalized.The total cost of the disaster was estimated at $100bn in May 2012.

History编辑本段回目录

Japan's nine electric companies, including TEPCO were established in 1951 with the end of the state-run electric industry regime for national wartime mobilization.[11][12]

In the 1950s, the company's primary goal was to facilitate a rapid recovery from the infrastructure devastation of World War II. After the recovery period, the company had to expand its supply capacity to catch up with the country's rapid economic growth by developing fossil fuel power plants and a more efficient transmission network.

In the 1960s and 1970s, the company faced the challenges of increased environmental pollution and oil shocks. TEPCO began addressing environmental concerns through expansion of its LNG fueled power plant network as well as greater reliance on a 'deal with the devil'- nuclear generation. The first nuclear unit at the Fukushima Dai-ichi (Fukushima I) nuclear power plant began operational generation on March 26, 1971.

During the 1980s and 1990s, the widespread use of air-conditioners and IT/OA appliances resulted a gap between day and night electricity demand. In order to reduce surplus generation capacity and increase capacity utilization, TEPCO developed pumped storage hydroelectric power plants and promoted thermal storage units.

Recently, TEPCO is expected to play a key role in achieving Japan's targets for reduced carbon dioxide emissions under the Kyoto Protocol. It also faces difficulties related to the trend towards deregulation in Japan's electric industry as well as low power demand growth. In light of these circumstances, TEPCO launched an extensive sales promotion campaign called 'Switch!', promoting all-electric housing in order to both achieve the more efficient use of its generation capacity as well as erode the market share of gas companies.

Community compensation

Tokyo Electric Power could face 2 trillion yen ($23.6 bln) in special losses in the current business year to March 2012 to compensate communities near its crippled Fukushima nuclear plant, according to JP Morgan.

Japan plans to put TEPCO under effective state control so it can meet its compensation payments to people affected by radiation from its Fukushima I plant. Tokyo will set aside several trillion yen in public funds that TEPCO can "dip into if it runs short for payouts to people affected".

Salary pay cuts编辑本段回目录

The company workers agreed to a management proposal to cut their pay as a sense of responsibility for the world's worst nuclear disaster. Annual remuneration for board members will be reduced by 50 percent since April 2011, while payment for managers will be cut by 25 percent and workers by 20 percent both since July 2011 and bonuses since June 2011. The company expects to save about 54 billion yen ($659 million) a year from the pay cuts.

In July 2012 it was announced that annual salaries of managers will be reduced by at least 30%, with workers pay cut remaining at 20%. On average employees pay would be cut by 23.68%. In addition, the portion of the employee health insurance program that the company covers will be reduced from 60% to 50%, the standard in Japan.

Sale of hospital编辑本段回目录

In was announced in July 2012 that the company would sell the hospital it owns in Shinjuku Ward in Tokyo. The hospital is used exclusively by current and former TEPCO employees and their families. Its market value is ¥8.6 billion.

Position in the industry

TEPCO is the largest electric utility in Japan and the 4th largest electric utility in the world after German RWE, French Électricité de France and Germany's E.ON. As TEPCO stands in a leading position in this industry, they have relatively a strong effect for Japanese economics, environment, and energy industry.

Management and finance
For the fiscal years ending in 2011, 2012 the company had a pretax loss, in 2013 the deficit was 377.6 billion yen. In the following year 2014 red figures were expected too.

Generation
The company's power generation consists of two main networks. Fossil fuel power plants around Tokyo Bay are used for peak load supply and nuclear reactors in Fukushima and Niigata Prefecture provide base load supply. Additionally, hydroelectric plants in the mountainous areas outside the Kanto Plain, despite their relatively small capacity compared to fossil fuel and nuclear generation, remain important in providing peak load supply. The company also purchases electricity from other regional or wholesale electric power companies like Tohoku Electric Power Company, J-POWER, and Japan Atomic Power Company.

Transmission and distribution

The company has built a radiated and circular grid between power plants and urban/industrial demand areas. Each transmission line is designed to transmit electricity at high-voltage (66-500kV) between power plants and substations. Normally transmission lines are strung between towers, but within the Tokyo metropolitan area high-voltage lines are located underground.

From substations, electricity is transmitted via the distribution grid at low-voltage (22-66kV). For high-voltage supply to large buildings and factories, distribution lines are directly connected to customers' electricity systems. In this case, customers must purchase and set up transformers and other equipment to run electric appliances. For low voltage supply to houses and small shops, distribution lines are first connected to the company's transformers (seen on utility poles and utility boxes), converted to 100/200V, and finally connected to end users.

Under normal conditions, TEPCO's transmission and distribution infrastructure is notable as one of the most reliable electricity networks in the world. Blackout frequency and average recovery time compares favorably with other electric companies in Japan as well as within other developed countries. The company instituted its first-ever rolling blackouts following the shutdown of the Fukushima I and II plants which were close to the epicenter of the March 2011 earthquake. For example on the morning of Tuesday, March 15, 2011, 700,000 households had no power for three hours.The company had to deal with a 10 million kW gap between demand and production on March 14, 2011.
