For the January-November period, electricity use increased 6.5 percent year-on-year, a rise of 1.5 percentage points from the same period of last year.

In the first 11 months, electricity use in the service sector maintained double-digit growth, up 10.5 percent year-on-year, but the increase was 1.1 percentage points slower than a year earlier.
