the line operated initially at only 10% of capacity. in the 1990s, prior to major social unrest, the line increased its power transmission to 200 mw, still considerably below design capacity. as of 2000, reliability had been poor with many thyristor failures at the inverter station. as of 2010, the line was still functional as far as bandundu, the capital of bandundu province, approximately northeast of kinshasa. in 2009 abb was awarded a contract to refurbish and modernise the converter equipment. this upgrade is due to be completed in 2013.
