The crisis-hit nation saw the amount it must pay for 1,000 cubic metres of blue fuel soar to USD 485.50 from USD 268.50 after Russia imposed two price increases in three days that reflected its deep displeasure with the ex-Soviet nation's new westward course.
Energy Minister Yuriy Prodan called the new rate "political" and vowed to explore solutions that included a heavier reliance on coal - a polluting resource whose consumption has imperilled the air quality of nations such as China.
Ukraine has relied on coal throughout much of the past century despite efforts by global institutions such as the World Bank to help Kiev phase out its use following independence from Moscow.
The International Energy Agency estimates that coal accounts for about 30 per cent of Ukraine's total energy supply compared to the 40 per cent of the balance assumed by natural gas.

"There is a probability of Ukraine reducing gas purchases from Russia," Moscow's VTB Capital investment bank wrote in a research note.
