Solar power generation in winter in Northeast China

Future solar power were projected to generally increase in east and central China but decrease in solar-energy-abundant regions. Radiation was the most robust factor for future solar energy trend over China, however wind speed can not be ignored over Tibetan Plateau.

Monthly solar PV power generated in China 2021-2024. Solar photovoltaic energy generated in China from January 2021 to July 2024 (in terawatt hours).

This study identifies suitable sites for onshore wind and solar PV deployment, estimates the potential of electric power generation capacity and electricity generation under different scenarios, and estimates an hourly power generation curve for various regions.

Based on international experience and an understanding of the overall situation in the Northeast region and China, we have conducted a retrospective analysis of peak load winter demand and power incidents in the Northeast power grid area, with the hope of providing valuable insights for future assessments of power system resource adequacy.

As concluded, the wind and solar fluctuations in North China are notable, accounting for 28.1% and 25.0%, respectively, of the total prediction error in China, especially during winter.

6 FAQs about [Solar power generation in winter in Northeast China]

What should China do about wind and solar energy development?

Based on the prediction error analysis, we summarize two policy suggestions for China. First, the government should provide adequate policy support and incentives to encourage wind energy development in the Southwestern and Central areas of China and solar energy development in the areas of Southwest and Northwest China.

How much electricity can China generate from wind and solar energy?

First, results show that China can obtain 12,900–15,000 TWh/yr from wind energy resources and 3100–5200 TWh/yr from solar. The upper bound of electricity generation potential from both wind and solar resources is three times the demand in 2019, and one-and-a-half times the demand expected for 2050.

Should China develop wind and solar energy simultaneously?

The seasonal patterns show that China should develop wind and solar energy simultaneously, to exploit wind’s highest potential during winter and early spring, and solar’s higher production during late spring and summer.

Can wind power offset winter load peak in North and Northeast China?

Due to the obvious seasonal distribution of offshore wind power, which dominates in spring and winter 51, wind power represents a suitable alternative resource to offset the winter load peak in North and Northeast China. Based on the prediction error analysis, we summarize two policy suggestions for China.

How big is China's solar & wind power capacity?

Wind and solar now account for 37% of the total power capacity in the country, an 8% increase from 2022, and widely expected to surpass coal capacity, which is 39% of the total right now, in 2024. Cumulative annual utility-scale solar & wind power capacity in China, in gigawatts (GW)

Where is solar energy found in China?

In terms of solar energy, there are more than 50,000 km2 where the solar resource has a capacity factor exceeding 0.15. This accounts for over 0.5% of China’s land area. More than half of this land is located in Northwest China, followed by North China and Northeast China.
