As temperatures soar across the country, China is taking measures to maintain a stable electricity supply.

The country's peak power load has hit record highs twice this summer, reaching a maximum of 1.467 billion kilowatts -- an increase of about 150 million kilowatts compared with the same period last year, according to the latest data released by the National Energy Administration (NEA).

In particular, the power grid load in 10 provinces, including Shandong, Jiangsu, Anhui, and Fujian, has reached record highs 22 times, the data shows.

To ensure a stable power supply, all 162 key power grid projects designed to meet this summer's peak electricity demand were put into operation by the end of June.

Meanwhile, China has made full use of ultra-high voltage power grids to boost cross-regional and cross-provincial power transmission. The maximum power transmitted by the State Grid Corporation of China (State Grid) has exceeded 225 million kilowatts.

According to the NEA, the national coal supply is stable and well-managed, with coal stockpiles at major power plants continuing to grow.

As for oil and gas reserves, the natural gas supply is secure, with cumulative injections into underground storage facilities exceeding 11 billion cubic meters.
