The three power distributors operating in Bulgaria have requested from the 
country's energy regulator to approve an increase in electricity prices as of 
July 1, local media reported.
The local power distribution unit of 
Austria's EVN seeks an increase in the daytime electricity tariff by 8.0% while 
the units of Czech companies CEZ and Energo-Pro applied for an increase of 13% 
-14%, the Bulgarian News Agency, BTA, reported on Wednesday, quoting the energy 
regulator's head Boyan Boev.
The three companies also requested an 
increase in the night-time tariff to double the daytime rates, Boev 
said.
CEZ’s current daytime electricity tariff is set at 0.14949 levs 
($0.1053/0.0764 euro) per kilowatt-hours (kWh) while the customers of EVN 
Bulgaria and Energo-Pro pay daytime price of 0.15327 levs 0.15958 levs per kWh, 
respectively.
Nigh-time rates per kWh are set at 0.08508 levs for CEZ, 
0.08676 levs for EVN Bulgaria and 0.08862 levs for Energo-Pro.
The State 
Energy and Water Regulatory Commission (SEWRC) has to come up with a decision on 
the power distributors' proposed tariff by June.
In March SEWRC said it 
had been notified by state-owned power utility NEK that the outstanding payments 
of the local power distribution units of the three companies to NEK exceed 347.6 
million levs in total, and that it would launch a procedure to revoke their 
licences.
The power distributors have said they owe the debt-ridden NEK 
nothing, claiming that it had failed to pay them the money the were due in 
compensation for being obliged to buy electricity generated by wind and solar 
power installations.
