6 Frequently Asked Questions about “A large number of outdoor power supplies bear the load”

Do peak loads support China's long-term power system planning?

To support China's long-term power system planning, this study estimates the response functions of annual peak loads to maximum temperatures in China and then predicts the future peak loads under different scenarios.

Where is peak electricity load data obtained?

The peak electricity load data is drawn from the power dispatch reports from China Electricity Council (CEC). The annual maximum temperature data is obtained from China Meteorological Administration (CMA).

Why is peak load important?

On the other hand, peak load is an important basis for power system design and planning. In order to meet the peak demand, the “rule of thumb” of long-term infrastructure investment is to establish a capacity surplus of at least 15% of the peak load (Burillo et al., 2019).

How many kilowatts is Shanghai's grid load?

The grid load peaked at 40.302 million kilowatts on Friday, coinciding with an intense heat wave that has enveloped Shanghai since late July, according to the State Grid Shanghai Municipal Electric Power Company.

How can China meet a rising peak load?

At the same time, the national peak load in China has been growing rapidly in recent years, which reached 1003 GW in 2018. To meet this rising peak load, a large amount of money needs to be invested into the electricity supply infrastructure (generators, transmission and distribution lines, and transformers).

What is the national peak load in 2100?

Using the estimated load-temperature response functions, the national peak load is expected to reach between 3807 GW and 6815 GW in 2100 under different climate and socio-economic scenarios.
