The largest deposit is at Tkibuli (268 million tons of proven reserves and 700 million tons of potential reserves, 80 per cent of the country’s total). Indications are that coal deposits may be found elsewhere in the country, but exploration has been discontinued since the 1980s. Plans call for boosting oil production to 3 million tons per year by 2020, and gas production to 2 bcm by the same date. Within the last five years, there has been a steady increase in coal production, reaching 189.5 ktoe in 2012.
