Why is it important to assess photovoltaic power generation potential in China?

Clear spatial dislocations between PV power generation potential and population distribution and electricity demand. Accurate assessment of the photovoltaic (PV) power generation potential in China is important for the reduction of carbon emission intensity and the achievement of the goal of Carbon Neutral.

What is the capacity potential for large-scale solar PV in China?

4. Discussion This work reports that the total capacity potential for large-scale PV in China is 108.22 TW with 150.73 PWh annual solar PV generation (implying an average capacity factor of 15.9), which can bring 150.28 billion tones of CO 2 emission mitigation caused by coal-fired power generation.

Which land is suitable for PV power generation in China?

The results showed that the average suitability score of land in China is 0.1058 and the suitable land for PV power generation is about 993,000 km2 in 2015. The PV power generation potential of China is 131.942 PWh, which is approximately 23 times the electricity demand of China in 2015.

What is the PV power generation potential of China?

The PV power generation potential of China was estimated using ERA5-Land hourly data with a spatial resolution of 0.1° × 0.1° (about 10 km × 10 km), and a temporal resolution of 1 h. The quality of the data of ERA5 has also been improved compared to the previous data .

Where is PV power generation mainly concentrated in Xinjiang & Inner Mongolia?

In terms of provinces, PV potential is mainly concentrated in Xinjiang, Inner Mongolia, Qinghai, and other provinces west of the Hu Huanyong Line (Population Distribution Line). The PV power generation potential of the provinces east of this line basically does not exceed 3 PWh, and most of them do not exceed 1 PWh.

Is the gap between PV potential and future electricity consumption closing?

The gap between the PV potential of each province and future electricity consumption is closing, and the ratio of supply and demand is decreasing, which has been calculated to be 39.8 and 30.8 in 2020 and 2030, respectively, under the scenario of 100% PV power generation.
