金兰水电站于1960年3月建成投产，原电站装机容量3×1360kW，已超龄运行多年，设备老化，严重影响着电站的正常安全运行．电站通过更换转轮，并对发电机等进行改造，使装机容量增至3×且800kW，机组效率提高了8％．工程总投资830万元，年增发电量351万kW·h，年增收入331万元，工程改造的经济效益十分显著．金兰水电站的更新改造，因地制宜，投资省见效快，进一步发挥了老电站的效益，为老电站更新改造走出了一条新路子．
The Jinlan Hydropower Station was put into operation in March 1960 and the installed capacity of the original power station was 3 × 1360 kW. It has been over-aged for many years and the equipment has been aged, seriously affecting the normal and safe operation of the power station. The power station increased the efficiency of the unit by 8% by changing the runner and renovating the generator and so on to increase the installed capacity to 3 × and 800kW. The total investment of 8.3 million yuan, an increase of 3.51 million kWh of electricity, the annual income of 3.31 million yuan, the economic benefits of reconstruction is very significant. The renovation and renovation of Jinlan Hydropower Station has taken measures to local conditions and the province of investment has achieved quick results, giving further play to the benefits of the old hydropower station and has taken a new path for the renovation and renovation of the old hydropower station.
