On November 28, the Kaihua Reservoir Project in Zhejiang Province, constructed by Sinohydro Bureau 12 Co., Ltd., successfully completed all procedures for grid-connected power generation and officially entered a new stage of commissioning and operation, marking a key breakthrough in the comprehensive utilization of water resources for the project and injecting strong momentum into the optimization of the energy structure in western Zhejiang.

The Kaihua Reservoir Project is located at the source of the Qiantang River. It is one of the 150 major water conservancy projects promoted by the state and a backbone project of the national water network. The catchment area above the dam site is 233 square kilometers, the total reservoir capacity is 184 million cubic meters, the normal water level is 251 meters, and the installed capacity of the power station is 13.8 megawatts. The reservoir project is of large (2) scale and is an important component of the flood control system of the Qiantang River Basin.

The Qianjiangyuan Power Station of the Kaihua Reservoir Project is located downstream of the power generation diversion tunnel, connected to the fish lift system, and adjacent to the spillway and access road, with convenient transportation. The power station is equipped with two 6,000 kW vertical-shaft Francis turbine-generator units and two 900 kW horizontal-shaft Francis turbine-generator units (ecological units). The core function of the ecological units is to ensure water for the downstream ecological environment. The operation of the two units can meet the ecological water demand during the wet season, and this can also be ensured through power generation by the main units. During flood periods, the two main units and the two ecological units can be started for combined power generation to improve power generation benefits and achieve the coordinated unity of ecological protection and energy production.

The power station started grid-connection work on November 25. Following the principles of "safety first, step-by-step implementation, and steady progress," it successively completed tests including line energization, main transformer and busbar energization, on-load voltage regulation, and phase verification. All types of protection tests passed, automated joint debugging was normal, and the grid-connection work was successfully completed.

Next, the Kaihua Reservoir Project will continue to carry out follow-up operation and maintenance support for the power station, ensure the long-term safe and stable operation of the power station, and make greater contributions to the sustainable utilization of water resources in the Qiantang River Basin, ecological environment protection, and high-quality economic and social development.
