Power business operations

As of the end of 2019, according to statistics from the National Bureau of Statistics, the total assets of large-scale power enterprises nationwide were 1,512.53 billion yuan, an increase of 5.4% over the previous year, and the growth rate increased by 2.8 percentage points over the previous year. Among them, the total assets of power grid enterprises increased by 9.9% over the previous year; the total assets of power generation enterprises increased by 2.2% over the previous year (the total assets of thermal power enterprises decreased by 0.3% over the previous year).

In 2019, the total liabilities of large-scale power enterprises were 879.89 billion yuan, an increase of 1.8% over the previous year, and the growth rate increased by 1.1 percentage point over the previous year. Among them, the total liabilities of power grid enterprises increased by 6.3% over the previous year; the total liabilities of power generation enterprises decreased by 0.5% over the previous year (the total liabilities of thermal power and hydropower enterprises decreased by 3.8% and 3.7% respectively compared with the previous year). In 2019, the total profit of large-scale power enterprises was 383.4 billion yuan, an increase of 18.1% over the previous year.

In 2019, all parties continued to implement the requirement of reducing the national average electricity price of general industrial and commercial enterprises by another 10%, reducing the electricity cost of enterprises by 84.6 billion yuan throughout the year. The total profits of power grid enterprises continued to decline, down 4.9% from the previous year's decline of 24.3%. The losses of loss-making enterprises was 14.5 billion yuan, an increase of 22.6% over the previous year.

China's Coastal Electric Coal Purchasing Price Index (CECI Coastal Index) shows that the average comprehensive price in 2019 is 576 yuan/ton, a decrease of 19 yuan/ton from the previous year, but it still exceeds the upper limit of the green range. As the scale of market-oriented transactions continues to expand and the country promotes electricity price reduction, the coal-fired power business of large power generation groups continues to suffer overall losses, and the losses of coal-fired power companies are still close to 50%. The growth rates of wind power and solar power generation profits were 3.5% and 7.3% respectively. However, due to the inadequate subsidies of most companies, the book profits of enterprises are difficult to convert into cash flow in the short term, resulting in difficulties in capital turnover.
