Exclusive | The latest progress of China’s First Batch CSP Demonstration Projects

Reported from CSPPLAZA: The severe cold in the Chinese borderland was described in many Tang poetries thousand years ago, and now many of the first batch of China’s CSP demonstration projects keep on constructing in such a cold winter, striving to get projects operated before the deadline of the end of 2018.

This article updates latest construction progress of China’s first batch demonstration projects in various regions. It should be noted that the temperature data listing below is derived from public meteorological data, and most projects are located in remote and open areas of the country, so the actual temperature of the project is generally lower than the temperature below.

Up to now, less than 10 projects in the demonstration projects have entered the stage of substantive construction, and about half of the projects has not begun to build for various reasons.

On the whole, the projects in substantive construction stage invariably choose to work in a certain speed during the winter. Though most concrete pouring construction has to be suspended due to the extreme weather, the work like the installation of collectors and indoor works can still be progressed. Meanwhile, concrete pouring work are unstopped in some projects under effective winter construction measures.

Project progress can be ensured to some extent by constructing in winter days, but the needed protective measures for winter construction will inevitably increase labor cost and construction expenditure.

But for those demonstration projects which can not be completed before the end of 2018 , the shorter they delay, the more likely for them to get a higher feed in tariff. Therefore, it is necessary for projects to be constructed even in cold winter.

Latest Progress

CGN Delingha 50MW Parabolic Trough CSP Project

This project is going to be the first operational commercial parabolic trough CSP Plant in China;

the overall installation of solar island has been completed;

the solar island, heat transfer and storage island, and power island are going through fractional commissioning;

grid-connecting work will be finished soon;

the specific work of the project in winter will depend on the actual temperature, and the working hours will depend on the weather too (“if the outdoor temperature is above -10℃, the outdoor commissioning will still be processed, if not, it will stop working but the indoor commissioning can be carried out normally.” said by a staff.).
