Bulgaria's state-owned power grid operator NEK said it is seeking an 8.5% increase in wholesale electricity prices as of July 1.
The company is proposing a tariff increase to 0.08105 levs ($0.0547/0.04144 euro) per kilowatthour (kWh) from 0.07469 levs per kWh at present, NEK said in a statement published on its website.
The company said the move was prompted by inflationary gains and the higher share of power output purchased from highly-efficient cogeneration facilities and from producers using renewable energy sources, among other factors.
NEK is also seeking a hike in the so called green energy tariff add-on to 12.35 levs per megawatthour (MWh) from 3.72 levs per MWh due to the increased share that electricity generated from renewable energy sources has in the country's overall energy balance.
The proposed tariff hikes have to be approved by the country's State Energy and Water Regulatory Commission.
