How was the project planned and approved?
The development of the Laluo Water Conservancy Project followed a structured sequence of planning, technical review, and administrative approval spanning several years. The foundational phase concluded in February 2005, when the Comprehensive Planning Report was finalized. This document established the core parameters for the hub and its associated irrigation districts, setting the stage for subsequent technical evaluations and governmental sanctions.
Technical Review and Regional Sanction
In April 2005, the finalized planning report underwent a critical technical review. The General Institute of Water Resources and Hydropower Planning and Design conducted this assessment, evaluating the engineering feasibility and hydrological data for the facility located on the right bank of the Yarlung Zangbo River. This review by the General Institute of Water Resources and Hydropower Planning and Design was essential for validating the project's design before it moved to regional authorities.
Following the technical validation, the project advanced to the regional level. In May 2006, the Tibet Autonomous Region officially sanctioned the project. This regional sanction was a key milestone, reflecting local government support for the infrastructure development in Laluo Township, Sa'gya County, Shigatse City. The approval by the Tibet Autonomous Region paved the way for final national-level endorsement.
National Approval
The final step in the pre-construction approval process occurred in October of the same year. The National Development and Reform Commission (NDRC) granted approval for the Laluo Water Conservancy Hub and Associated Irrigation District Project. This endorsement by the NDRC, the primary state agency responsible for formulating national economic and social development plans, confirmed the project's status as a significant infrastructure initiative. With the NDRC's approval secured, the project was cleared to proceed toward its eventual commissioning in 2020.
Construction and Operational Timeline
The construction of the Laluo Water Conservancy Project followed a structured timeline spanning several key phases, beginning with the official commencement of works in June 2014 (Tibet Daily). This initial phase involved extensive preparatory works on the right bank of the Yarlung Zangbo River in Laluo Township, Sa'gya County, Shigatse City. The project's strategic location required careful engineering to manage the river's flow and integrate the reservoir with the associated irrigation district infrastructure.
Flow Interception and Reservoir Formation
A critical milestone in the project's physical development occurred in September 2016, when the flow interception of the Yarlung Zangbo River was successfully completed (Xinhua). This event marked the transition from civil construction to the initial filling of the reservoir. The interception allowed for the stabilization of the riverbed and the beginning of water accumulation, which is essential for both the hydroelectric power generation capacity and the storage requirements for the supporting irrigation district. The successful diversion of the river demonstrated the effectiveness of the temporary cofferdams and pumping systems deployed during the construction period.
Power Generation and Trial Operations
The project achieved its first major operational milestone in December 2020, when the initial power generation started (People's Daily Online). This marked the beginning of the hydroelectric output from the facility, contributing to the regional energy grid. The commissioning of the power generation units confirmed the functionality of the turbines and the electrical infrastructure connected to the reservoir. Following the start of power generation, the project entered a phase of trial operations to optimize performance and integrate the various components of the water conservancy hub.
Trial Water Supply and Full Integration
In April 2021, the Laluo Water Conservancy Project initiated its trial water supply phase (Tibet Autonomous Region Government). This step was crucial for testing the irrigation distribution network that serves the associated irrigation district. The trial supply allowed engineers to monitor water quality, flow rates, and the efficiency of the conveyance systems. The successful completion of the trial water supply indicated that the project was ready for full operational integration, combining both hydroelectric power generation and agricultural water management functions. This dual-purpose operation enhances the economic and environmental sustainability of the region.
