Until the late 2010s Pyongyang still experienced frequent shortages of electricity. To solve this problem, two power stations – Huichon Power Stations 1 and 2 – were built in Chagang Province and supply the city through direct transmission lines. A second phase of the power expansion project was launched in January 2013, consisting of a series of small dams along the Chongchon River. The first two power stations have a maximum generating capacity of 300 megawatts (MW), while the 10 dams to be built under second phase are expected to generate about 120 MW. In addition, the city has several existing or planned thermal power stations. These include Pyongyang TPS with a capacity of 500 MW, East Pyongyang TPS with a capacity of 50 MW, and Kangdong TPS which is under construction.
