China News Service, Yinchuan, January 7 (Yu Jing) On January 7, the reporter learned from the State Grid Ningxia Maintenance Company that as of December 31, 2020, the cumulative external power transmission of Ningxia Power Grid exceeded 79 billion kWh, an increase of over 18 %, the electricity sold in the region is 70.379 billion kWh. Ningxia will achieve the first time in 2020 that DC power transmission exceeds the electricity sold in the region.
Ningxia is one of the important sending end of the national “West-to-East Power Transmission” project. The installed capacity of full-caliber power generation is 55.87 million kilowatts, and the installed capacity per capita ranks first in the country. Among them, new energy accounts for 46.07%. Ningxia is the main channel for power transmission.
According to the relevant person in charge of the Ningxia Trading Center, due to the impact of the epidemic, the power transmitted by the Ningxia Power Grid in the first quarter was greatly affected.
In order to complete the annual delivery goal, they communicated and reported through multiple channels and rounds. The Lingshao supporting power supply supplemented Zhejiang's electricity output of 1.9 billion kWh, and the Zhaoyi DC channel supplemented Ningxia's Shandong electricity supply of 600 million kWh; actively cooperated with power purchase provinces During the matchmaking negotiations, we will seize the rich space of Lingshao Channel to achieve an increase of 2.3 billion kWh in Zhejiang and Shanghai. At the same time, we will seize the opportunity of mutual agent trading with Northwestern provinces and send 1 billion kWh of electricity to Qinghai and Gansu.
A series of measures finally achieved 5.8 billion kWh of supplementary power.
At the same time, State Grid Ningxia Electric Power Co., Ltd. fully assisted the epidemic prevention and control and resumption of production in East China and North China, and played the role of power supply "stabilizer" and "ballast stone" at critical moments.
State Grid Ningxia Maintenance Company optimized the maintenance period from the previous average of 11 days to 5 days through a variety of scientific methods, and can add nearly 500 million kilowatt-hours of electricity.
In 2020, the energy utilization rate of Yindong DC will increase from 95.59% in 2019 to 97.4%.
Lingshao DC started to transmit power at 90% of the rated transmission capacity in mid-July, with an average daily power transmission of 173 million kWh and an annual external power transmission of 49.819 billion kWh, ranking first in the State Grid Corporation of China, achieving a new breakthrough in external power transmission .
The delivery provinces have also expanded from the original three provinces of Qinghai, Tibet, and Shandong to the current dozens of provinces including Shanghai, Zhejiang, Jiangsu, Hubei and Hunan.
Through the cross-regional direct current channel, Ningxia Electric Power has realized the optimal allocation of resources across the country, effectively taking advantage of Ningxia's local coal power and new energy resources.
In 2020, "outbound delivery" will be greater than "internal supply", recreating a Ningxia electricity sales market.
