KEPCO currently applies three-stage progressive rates for residential power usage, which creates a threefold difference in electricity bills paid by homes using a lot and those that are thriftier. Under the revision, the electricity use ceilings of the first two stages will be raised in July and August, allowing people to use more electricity at the same cost.
  
The revised system will be applied next month once the government makes the final approval.
  
Following the joint panel's recommendation last week, some KEPCO board of directors expressed their concerns that such changes to the progressive electric billing would force the company to lose up to 300 billion won in revenue and that government support is needed.
  
KEPCO posted an operating loss of 630 billion won in the first quarter of the year on a consolidated basis, widening from an operating loss of 128 billion won a year earlier, while its sales declined 2.9 percent on-year to 15.24 trillion won. (Yonhap)
