News from CSPPLAZA

This is Great News that so many CSP power would be built in future, and this is signal that Energy worldwide is always changing & improved.

On July 4th, 2022, 《The development and Reform Commission of Xinjiang Uygur Autonomous Region》 issued the notice on printing and distributing the list of the second batch of market-oriented grid connected new energy projects in the autonomous region in 2022 (see Annex).

 

This list includes 13 thermal storage solar thermal power generation projects with an installed capacity of up to 1.35gw! This seems to be releasing a strong signal that the configuration of photovoltaic + photothermal energy storage is expected to become the mainstream new energy power generation project scheme.

 

Solar Power catch the eye of worldwide:

It is understood that there are 49 power grid consumption projects included in the list, with a total of 30.47 million KW; There are 18 integrated source network load storage projects, with a total of 10.415 million KW. The total scale is 40.89gw (excluding energy storage and photothermal installation).

If the installed capacity of the regulated power supply (electrochemical energy storage and photothermal power generation) is added, the installed capacity of 6.9475 million KW needs to be added, including 1.35 million kw of photothermal power generation, accounting for 19.43% of the regulated power supply.

The proportion of 19.43% doesn’t sound high, but it is a very significant breakthrough for solar thermal power generation, which focuses on seeking a place in the project of scenery base.

 

More importantly, the vast majority of photovoltaic grid consumption projects have chosen the solar thermal storage scheme, accounting for more than electrochemical energy storage. Light and heat can be described as the first eye-catching among them!

The distribution and storage of wind power projects are all electrochemical energy storage, and the proportion of distribution and storage is almost more than 20%, some even more than 30%, and the duration is mostly 4 hours.

 

The distribution and storage methods of photovoltaic projects are divided into electrochemical energy storage and thermal storage photothermal. The proportion of photothermal energy storage is mostly about 11%, with a duration of 8 hours, and the proportion of electrochemical energy storage is about 25%, with a duration of 4 hours.

According to table 2, a total of 13 grid consumption projects adopt the configuration scheme of photovoltaic + thermal storage photovoltaic power generation, with a total scale of 12.15 million KW, a total installed capacity of 1.35 million KW, and a distribution and storage ratio of about 11%. Among them, the installed capacity of photovoltaic projects is mostly 900MW, and the installed capacity of photothermal projects is mostly 100MW + 8-hour heat storage.

 

Great significance

The economics of photovoltaic + electrochemical energy storage and photovoltaic + photothermal schemes are estimated.

The energy storage scale of 100000 kW / 400000 kwh is calculated according to the current cost of 1800 yuan / kWh of lithium battery energy storage system, and the one-time investment cost is estimated to be 400000 × 1800 = 720 million yuan. To build a 900000 kW photovoltaic project, it needs 90 ÷ 40 × 7.2 = 1.62 billion yuan of energy storage system investment.

 

The construction of a 100000 kW 8-hour energy storage (which has been significantly better than the 4-hour battery energy storage) solar thermal power generation project, with an estimated investment of 1.8 billion yuan, can be equipped with 900000 kW photovoltaic projects.

 

Based on the analysis above, Investors have shown a clear preference for the configuration scheme of photovoltaic + photothermal. This has never happened in the past history of light and heat.

It is trend that Clear Power would take more and more important role in future
