Some hydroelectric facilities were believed to be out of operation due to damage from major flooding in 1995. Coal-fired power plants were running well under capacity, due in part to a serious decline in coal supply and in part to problems with transportation of coal. The electricity supply steadily declined and was 17 TWh in 1998. Since electricity generated needed to be doubled just to return to the 1989 level, power shortages continued until coal production could increase substantially and generating equipment is refurbished. Transmission losses were reported to be around 30%.
