China's power generation rose 2.9 percent year on year to hit 1.09 trillion kWh in the first two months of the year, according to the National Bureau of Statistics (NBS).
The expansion was 3.4 percentage points lower than that for December.
NBS attributed the slowing growth to a high comparative base from the same period last year and the warm weather this year.
In February alone, the power generation climbed 6.8 percent from the previous year, much faster than the growth in January.
In breakdown, generation of hydroelectricity posted faster growth in the January-February period, rising 6.6 percent year on year, compared with a 0.9-percent decrease last December, while solar power production saw a 3.8-percent increase.
Electricity generated by thermal, nuclear and wind power facilities expanded at a slower pace, the NBS data showed.
