Bulgaria's energy regulator has decided to raise electricity prices by about 13% and natural gas bills by 4.88% as of July 1.
The hike of electricity prices is bigger than the initially announced 10%.
The price adjustment is due to the so called green energy tariff add-on, Angel Semerdjiev said during a parliamentary sitting on Friday.
The increase in natural gas prices is below the nearly 16% hike requested by the state-run gas monopoly Bulgargaz.
The energy regulator reviews electricity prices on a yearly basis and gas prices on a quarterly basis.
