Dongfang Electric Corporation (DEC)

China Dongfang Electric Corporation (DEC) is based inland at Chengdu, Sichuan province, and claims to be the largest power generation equipment manufacturer in the world. It was founded in 1984. An important subsidiary, Dongfang Electric Corporation Ltd (formerly Dongfang Electric Machinery Co Ltd), is listed in Hong Kong and Shanghai, and in April 2009 announced a CNY 5 billion capital raising. Dongfang has the largest market share for turbine generators, and was the main contractor for Qinshan II.

It produces everything from reactor pressure vessels and steam generators through to turbine generators. It is providing the reactor pressure vessels for Taishan 2 EPR and Ningde 1, and its steam generators will equip Taishan 2, Hongyanhe 1-4, Ningde 1, Fuqing 1-2 and Fangjiashan 1-2 projects, as well as the first four Hualong One units at Fuqing and Fangchengang. In 2005, DEC supplied the main equipment for nuclear island and conventional island of Ling Ao Phase II, with half-speed Arabelle turbine generator resulting from technical cooperation with Alstom.

The main DEC subsidiary is Dongfang (Guangzhou) Heavy Machinery Co (DFHM) near the coast, which has capacity to produce three sets of CPR-1000 forged equipment per year since 2010 as well as four sets of turbine generators. It has ASME N-stamp accreditation. DFHM was formerly known as Guangzhou Guangzhong (Nansha) Machinery Co Ltd, and it has a close relationship with CGN. It supplied the first Chinese-made 1000 MWe reactor pressure vessel (for Ling Ao) in June 2009. DFHM was established in 2004 by Dongfang Electric (now 57%) and China Erzhong, with several local investors. It has had a close relationship with Japan Steel Works since 2006, and under a 2008 contract with JSW imports large forged components for pressure vessels and steam generators from JSW.
