An energy crisis currently evident in Greece might spread to Bulgaria, Novinar daily reported.

Miners from Maritsa-Iztok mines plan to strike in case their wages remain unchanged. At the same time Sofia residents complain of power cuts.

Another problem stems from the decision of the State Energy and Water Regulatory Commission (SEWRC), which decided to cut expenditure for renovation works and salary increases in Sofia.

As a result, Sofia might experience problems with central heating and the supply of warm water, Novinar reported.

Sofia's central heating provider Toplofikatsia managing director Petko Milevski said that company losses could reach 30 million leva if SEWRC refused introducing a four per cent heating price hike.

SEWRC said that an average increase of 0.35 per cent was acceptable. Higher increase will make consumers unable to pay, commission representatives said.
