The country's second-largest electricity gentailer says rising electricity prices are the result of rising lines charges.
Inflation's now back up at three-percent.
The single biggest driver is electricity prices - which have increased 11.3 percent in the past year.

He says they rose by about 20-percent last year and about 16-percent this year.
