Power Development Co., Ltd.(Dengenkaihatsu,English: Electric Power Development Co., Ltd.) Is JapanesePower company([3],Transmission company[4]).Nickname isJ-POWER(J-Power).


Pacific WarAfter the defeat of JapanGHQMade by the instructions ofExcessive Economic Force Concentration Exclusion LawReceived the designation ofJapan shipping lineWas dismantled and split into a regional power company.However, the newly-divided regional power companies are also very poor in capital and cannot supply the electricity needed for reconstruction satisfactorily.Power plantNewly establishedinvestmentSince it was in a state of being unreliable, the Electric Power Development Promotion Law enacted in response to the increase in domestic electricity demand1952Country on September 9thSpecial companyEstablished as (Capital composition 66.69% is Minister of Finance,-laterMinister of Finance, 9 for the restPower companyInvested).

The first big business of electric power developmentSakuma DamHowever, the construction, which takes 10 years, was completed in 3 years by introducing technology from the United States.With this success, Kansai Electric Power Co., Inc.Kurobe DamThere is also a story that gave a go-ahead to the construction of[Source required]..Subsequently called "OTM"Okutadami Dam,Tagokura Dam,Miboro DamConstruction of hydroelectric power plants including large-scale ones one after another.Supporting post-war reconstruction from the aspect of electric power (The Sakuma power plant of Sakuma Dam is still the largest hydroelectric power plant in Japan with annual power generation, and these are still one of the largest in Japan).

During the period of high economic miracle, the supply capacity was increased together with the electric power companies that had rebuilt their finances in response to the large increase in electric power demand. It was.On the other hand, power development includes wide-area thermal power plants that can be used by multiple electric power companies, interconnection transmission lines between electric power companies, andSakuma Frequency ConverterConstruction of interconnection facilities such as, long-distance DC power transmission, and large-scale pumped storage power plants.Perform complementary business of electric power companies.

After that, the electric power companies also had a sufficient financial structure and constructed interconnection transmission lines and other interconnection facilities between the companies.For power development, in order to support the domestic coal mine industry, which was declining at that time, we built a thermal power plant dedicated to domestic coal (later changed to overseas coal-fired power plant), and conducted demonstration test plants such as seawater pumping power plants and overseas cooperation projects. It has come to carry out business with a strong national policy, such as actively conducting it.

In 1997Special corporationAfter a preparation period of about 5 years in rationalizationPrivatizationBy doing so, the Cabinet decided2003Abolished the Electric Power Development Promotion Law,2004May 10ToTokyo Stock ExchangeIn the second partListingHowever, all of the shares held by the electric power company and the government-sponsored privatization fund were sold (initial price was 2,795 yen).In addition, the nickname was changed from "Denpatsu" to "J-POWER".

Now in JapanHydraulic power,FirepowerIt has more than 60 power plants in total, and its power generation capacity is outstanding except for the former general electric power companies (10 electric power companies), even when compared with the former general electric power companies.Shikoku Electric PowerEtc.Tohoku Electric PowerComparable to.In particular, coal-fired power generation is the largest in Japan, and hydroelectric power generation is also top class.It also owns a large number of power transmission / substation facilities, interconnection transmission lines between electric power companies, and other interconnection facilities, and in particular, only J-POWER has a transmission network that interconnects Honshu and Kyushu.Previously, only J-POWER had interconnections between Hokkaido and Honshu, between 50Hz and 60Hz, and between Honshu and Shikoku, but now it owns two-thirds, 3%, and 2%, respectively. ..Although it does not currently have a nuclear power plant, it is located in Aomori Prefecture.Oma Nuclear Power StationIs under construction. Wind-power generationAlso aboutTokyo Seaside Wind Power StationIt has 18 points in Japan and is top class (as of the end of March 2011).Even overseasポーランドWe are actively developing, such as participating in the business at Zayatsukobo Wind Farm.

Also, in recent yearsPower liberalizationDiversified business (water supply business, etc.) to respond to the trend.At the same time, so far mainly in the Asian regionConsultingIn recent years, we have been actively investing in overseas businesses that have been developingThailand・ Kaenkoi 2 power plant,The United States of America・ Tenasca Frontier, Elwood, Green Country, etc.), Coal Mine Development (Australia・ It is expanding due to (Claremont Coal Mine, etc.).
