Ertan Hydropower Development Co. Ltd. (EHDC) has named U.S-based engineering firm MWH to provide engineering and construction management services for EHDC’s 3,600-MW Jinping 1 hydroelectric project, to be built on China’s Yalong River.
MWH said July 30 it anticipates earning US$5 million over five years from its work on the 24.6 billion renminbi (US$3.3 billion) project.
Jinping 1 is to include a 305-meter-tall double-curvature, thin arch dam, providing significant flood control in addition to hydropower generation.
MWH is to be involved in construction quality control for concrete construction. It is to provide project and executive management training, as well as a full-time, on-site concrete expert to assist with planning, execution, quality assurance, and quality control of the concrete dam.
ï¿½EHDC and MWH have worked together since the early 1980s and have developed a strong, mutually beneficial relationship,ï¿½ EHDC General Manager Chen Yunhua said.
MWH provided dam design optimization and geological assessment services to EHDC for Jinping 1 in 2002 in Sichuan Province of southwest China. In the 1980s, MWH provided engineering and construction management consulting to EHDC for the 3,300-MW Ertan hydroelectric project, the first on the Yalong River, finished in 1999, and China’s largest hydro project completed in the 20th Century.
Jinping 1 is one of 21 hydropower schemes planned for the 1,571-kilometer Yalong River, which is estimated to have 34.62 GW of hydropower potential. Planned development includes construction of 4,800-MW Jinping 2, 1,800-MW Guandi, 400-MW Tongzilin, and 3,000-MW Lianghekou by 2025. Jinping 2 is already under construction 17 kilometers downstream from Jinping 1. (HNN 12/14/06)
