Successful Practice in Management Reform——An Analysis of Experiences with Guangzhou Pumped Storage PowerStation

Luo Shaoji

Strategic Study of CAE 2000, Volume 2, Issue 11, Pages 52-59

Abstract:

The 2 400 MW Guangzhou pumped storage project became fully operational in March 2000, thus establishing itself as the biggest of its kind in the world.

Based upon successful experiences with the project, the author spotlights the management practices in the four parts: that is project management improvements, reforms on construction management, reforms on plant operation management and reforms on business strategy. Thanks to the above-said reform efforts, the project turns out to be quite a success in terms of cost saving, fast progress, good engineering quality, rich returns plus a friendly environment.
