Power utility PPC has implemented a clause enabling tariff hikes if CO2 emission right costs exceed limits, and vice versa, beginning November 1, as had been announced by state-controlled corporation and the energy ministry.

Even so, no tariff hikes are seen in the next few months, according to sources at PPC and the ministry, but cost increases cannot be ruled out after winter.

For the time being, PPC’s tariff prices remain unchanged at levels set on September 1.

Meanwhile, RAE, the Regulatory Authority for Energy, is soon expected to reach decisions on various cost-related clauses adopted by electricity suppliers. Public consultation was staged last Spring to examine the level of transparency of surcharges included on electricity bills.

The authority is expected to soon decided on a standard formula for CO2-related clauses, sources informed.

RAE is also examining whether PPC’s CO2 clause breaches any supply code rules, sources added.
