Water and electricity 3,622 hours, a decrease of 203 hours. Nuclear power 7,802 hours, an increase of 352 hours year-on-year. Grid-connected wind power for 2,232 hours, an increase of 154 hours year-on-year. Grid-connected solar power generation for 1,281 hours, the same as the previous year.

Secondary power consumption

1. Electricity consumption in the whole society increased by 10.3% year-on-year, with the growth rate falling quarter by quarter

According to the data released by the National Energy Administration, in 2021, the whole society consumed 8312.8 billion KWH of electricity, an increase of 10.3% over the same period in 2019, an increase of 14.7% over the same period in 2019, and a two-year average increase of 7.1%. Influenced by factors such as the overall economic recovery, foreign trade and export, and the low base effect of power consumption growth caused by the novel coronavirus pneumonia epidemic, electricity consumption has rebounded sharply. In 2021, the growth rate of electricity consumption in the whole society reached a new high in the past decade, slightly lower than the 14.8% in 2010 and 12.0% in 2011.

In the first, second, third and fourth quarters, the electricity consumption of the whole society increased by 21.2%, 11.8%, 7.6% and 3.3% respectively, and the year-on-year growth rate fell significantly quarter by quarter.

In the first quarter, the electricity consumption of the whole society drove the annual electricity consumption to increase by 4.5 percentage points year-on-year, an increase of 14.4% over the same period in 2019. Among them, secondary power consumption became the main driving force for the growth of electricity consumption in the whole society, with a year-on-year increase of 24.1%, an increase of 15.4% over the same period in 2019, and a contribution rate of 72.8% to the growth of electricity consumption in the whole society. In the second quarter, the growth rate of electricity consumption in various industries declined compared with the first quarter, but the power consumption in primary industry still maintained a steady and substantial growth, and the growth rate of power consumption in tertiary industry recovered to the same period in 2019. Although the growth rate of electricity consumption in the high-tech and equipment manufacturing industry was significantly higher than the average level of the manufacturing industry in the same period, due to the gradual implementation of the blind development policy of the state to resolutely curb the "two high" projects, the growth rate of the four major high-load energy industries gradually fell, the growth rate of the second industry in the third and fourth quarters was directly affected, and some areas were affected by the epidemic. In 2021, the two-year average growth rate of electricity consumption in the whole society is 7.1%, and the two-year average growth rate in each quarter is 7.0%, 8.2%, 7.1% and 6.4%, maintaining steady growth overall.

2. The structure of electricity consumption continues to optimize, and the proportion of secondary power consumption decreases year by year

In 2021, while the electricity consumption of the whole society maintains steady growth, the electricity consumption structure is increasingly optimized. The primary industry consumed 102.3 billion KWH of electricity, up 16.4% year on year and up 14.6% on average in two years. Electricity consumption in the secondary industry was 5,613.1 billion KWH, up 9.1% year on year and up 6.4% on average in two years. Electricity consumption in the tertiary industry was 1,423.1 billion KWH, up 17.8% year on year and up 9.5% on average in two years. Domestic electricity consumption of urban and rural residents was 1,174.3 billion KWH, up 7.3 percent year on year and up 7.0 percent on average in the past two years.

The proportion of electricity consumption in the secondary industry gradually shrank, and the proportion of primary industry and tertiary industry slightly expanded. With the continuous improvement of rural electricity conditions, the further rapid development of high-tech and equipment manufacturing, charging and replacing service industries, emerging service industries, and the improvement of urban and rural residents' living standards, the electricity structure will further tilt to the primary and tertiary industries.
