POWERCHINA has begun construction of CSP in Delingha

POWERCHINA NORTHWEST, a subsidiary of Northwest Engineering Corporation Limited, has commenced construction on the 200MW solar tower CSP project in Delingha. This project is part of CGN New Energy’s Delingha solar hybrid initiative, boasting a total capacity of 2000MW across two phases.

Each phase comprises 800 MW of PV and 200MW CSP, covering approximately 53,000 mu (3529.8 million square meters). Utilizing a hybrid approach of photovoltaic and molten salt solar thermal power generation, the project harnesses solar field heat and residual electricity from curtailed wind and solar power.

By heating molten salt in thermal energy storage tanks, high-temperature steam is generated through a salt-water heat exchanger to drive steam turbine generators, resulting in electricity production. Projections estimate an annual utilization of 1,319 hours for the 200MW CSP plant, generating 263.88 million kWh annually. Upon completion, the project aims to contribute significantly to annual on-grid electricity generation, potentially reaching 3.65 billion kWh.
