KIEV, April 27 - The Ukrainian government on Wednesday unified natural gas tariffs for consumers as it seeks to meet demands by the International Monetary Fund to secure financial aid.

The move to introduce one flat tariff was announced by new Prime Minister Volodymyr Hroysman, whose election to office ended months of political turmoil that has hampered talks with the IMF to unlock $1.7 billion in new loans in exchange for reforms aimed at transforming Ukraine's battered economy and ending widespread corruption.

"This is consistent with the Ukrainian obligations to the International Monetary Fund," Hroysman told a government meeting, adding that the decision could reduce gas prices for some consumers.

Most, however, will face higher prices, complying with IMF calls for Ukraine to increase energy tariffs for households and utilities in an effort to reduce budget subsidies for state-run energy company Naftogaz.

Hroysman said that new single tariff to come into effect next month will be 6,879 hryvnia ($272) per 1,000 cubic meters of gas used.

The outgoing two-tier system's winter pricing was 3,600 hryvnias per 1,000 cubic meters for up to 1,200 cubic meters of gas, rising to 7,188 hryvnia for consumption above 1,200 cubic meters.

Most Ukrainian households use slightly more than 1,200 cubic meters during the winter, according to Naftogaz.

The new system should also help to reduce corruption in the sector, Hroysman said.

The old system was open to manipulation, Hroysman said, through the sale to industrial users of higher-priced gas that was meant to be sold to households at lower prices. (rt/ez)
