While China's photovoltaic industry has achieved rapid development in the first half of this year, some problems are gradually being exposed. Among them, the problem of "abandoning light" is especially shocking. At the seminar on "Photovoltaic Industry Development and the Second Half of the Outlook for the First Half of 2015" held by the China Photovoltaic Industry Association, Li Qionghui, director of the New Energy and Statistics Institute of the State Grid Energy Research Institute, said that from January to June this year, the State Grid Region ( Excluding Mengxi) The cumulative “discarded†power reached 1.733 billion kWh, all concentrated in the three provinces of Gansu, Qinghai and Xinjiang in the northwest.
The three western provinces and regions are "abandoning light" seriously
According to data released by the China Photovoltaic Industry Association, in the first half of this year, China's new photovoltaic installations were about 7~8 GW, and the cumulative installed capacity reached 35 GW. Due to the low profit margin in the manufacturing sector, many traditional companies have begun to invest in photovoltaic applications in recent years.
It is understood that in the first quarter of this year, China's photovoltaic power generation increased the filing capacity of 11.29 million kilowatts. Among them, the power station was 9.26 million kilowatts, accounting for 82%, which was basically the same as last year. The newly added grid-connected capacity of the country is 3.99 million kilowatts, and Inner Mongolia, Gansu and Xinjiang rank among the top three. Among them, the power station is 3.27 million kilowatts, accounting for 82%. In the first quarter of this year, the average number of hours of full-load PV power plants nationwide was 294 hours. In the first half of the year, the total number of hours of PV power plants nationwide was about 560 hours.
However, after the policy environment is getting better and the market order is gradually improving, the problem of “abandoning light†continues to ferment. It is understood that in the first half of this year, Gansu’s “abandonment of light†problem was the most prominent. From January to June, the accumulated “discarded†electricity was 1.141 billion kWh, accounting for 65.8% of the “discarded†electricity in the State Grid. Followed by Xinjiang, from January to June, the accumulated “discarded†electricity was 463 million kwh. From January to June, Qinghai accumulated a total of 128 million kWh of “discarded lightâ€. Qin Hao, an engineer of the New Energy Department of the Hydropower and Water Conservancy Planning and Design Institute, said at the seminar that Qinghai Haixi, Xinjiang Hami, and northern Gansu are the "hardest hit areas" of this year's "abandonment of light" problem. “The proportion of 'abandonment of light' in some areas is higher than the average in the province. In some areas, the rate of 'abandoning light' is about 15%, and the rate of 'abandoning light' in individual projects has even reached 30% to 40%.†Qin said.
Greater scope should be considered
The phenomenon of "abandoning light" is not a new problem. Although the reasons for the “discarding†power restrictions vary from place to place, they are basically affected and restricted by factors such as weak local capacity to absorb, lagging power grid construction, and limited capacity of external transmission channels.
“There are different levels of 'abandonment of light' problems in some areas of Gansu, Qinghai and Xinjiang, mainly due to factors such as unreasonable development layout and unsynchronized construction of supporting power grids, which has led to the recurrence of contradictions in photovoltaic power plants in these areas.†Li Qionghui said .
Since 2011, China's photovoltaic industry has a “rushing tide†every year, especially in the past two years. It is understood that in the first three quarters of 2014, the installed capacity of photovoltaics in China was actually only 400 megawatts, while the scale of “catch-up†in the fourth quarter exceeded 600 megawatts. Due to the short construction period of the photovoltaic power station, the power station is often built, and the supporting line is still lagging behind.
Although “abandonment of light†is serious, relevant statistics show that in the first half of this year, the top three PV grid-connected capacity in the national grid area are still the three provinces of Gansu, Qinghai and Xinjiang.
“By the size limit of the power consumption market in Qinghai Province, even if the double-digit growth is calculated according to the load, by 2020, the photovoltaic consumption in Qinghai Province is still seriously insufficient. In Qinghai, the photovoltaic power is not considered for wider consumption. The long-term 'discarding' power-limiting problem of the newly installed PV installations in the province will be difficult to avoid." Li Qionghui said.
