FACTBOX - West Balkans gas supply disruption

(Reuters) - Following is a summary of the impact of the disruption of Russian natural gas supplies to the Western Balkans amid a row with fellow former Soviet republic Ukraine on Tuesday:

CROATIA

Oil and gas group INA said that delivery of Russian gas to Croatia was at 20 percent of normal on Tuesday after a cut off early in the morning. Croatia imports 40 percent of its annual gas needs and INA called on consumers to reduce consumption.

Natural gas represents about a quarter of total fuel use.

Croatia produces 4.8 million cubic metres of gas daily and imports 3.1 million cubic metres from Russia, according to the economy ministry. Due to low winter temperatures, it is consuming 12 million cubic metres of gas daily, with the difference of about four million cubic metres coming from its reserves.

Local media reported the country has about 410 million cubic metres of gas.

MACEDONIA

Macedonia's natural gas supply was cut on Tuesday on its Orthodox Christmas Eve. Only one percent of Macedonia's energy consumption stems from natural gas, according to a July 2008 report by Analytica, a Skopje-based think tank.

"Macedonia has gas reserves for only a couple of days. It's going to have an impact on companies that are run solely on gas, but the number of those is very small," said Krste Miladinov, general manager of Gama, Macedonia's gas company which is half owned by the government.
