BEIJING, July 21 -- Two leading Chinese power companies reported lower electricity generation as the economy slows.

Huadian Power International Corporation Limited reported on Tuesday that the total amount of power generated in H1 decreased 7.29 percent from the same period a year earlier. The corporation's total amount of on-grid electricity tumbled 7.33 percent in the first half of last year.

Last week, Datang International Power Generation Co., Ltd. reported that its power generation had dipped 4.32 percent. Total on-grid power decreased 4.10 percent.

China's total electricity consumption in the first six months climbed 1.3 percent over the same period in 2014, according to National Energy Administration. The growth was significantly slower than last year's 5.3 percent.

The electricity consumption is expected to recover in the second half as easing policies revive industrial production. The industrial output in June picked up to 6.8 percent for the third straight month since a growth of 5.6 percent in March.
