Thanks to the abundance of natural resources like coal, iron and limestone, as well as good land and water transport systems, it was the first industrial city to emerge in North Korea after the Korean War. Light and heavy industries are both present and have developed in parallel. Heavy manufactures include cement, industrial ceramics, munitions and weapons, but mechanical engineering remains the core industry. Light industries in Pyongyang and its vicinity include textiles, footwear and food, among others. Special emphasis is put on the production and supply of fresh produce and subsidiary crops in farms on the city's outskirts. Other crops include rice, sweetcorn and soybeans. Pyongyang aims to achieve self-sufficiency in meat production. High-density facilities raise pigs, chicken and other livestock. 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. Retail Pyongyang is home to several large department stores including the Pothonggang Department Store, Pyongyang Department Store No. 1, Pyongyang Department Store No. 2, Kwangbok Department Store, Ragwon Department Store, Pyongyang Station Department Store, and the Pyongyang Children's Department Store. The city also has Hwanggumbol Shop, a chain of state-owned convenience stores supplying goods at prices cheaper than those in the jangmadang markets. Hwanggumbol Shops are specifically designed to control North Korea's expanding markets by attracting consumers and guaranteeing the circulation of money in government-operated stores. Transportation Pyongyang is also the main transport hub of the country: it has a network of roads, railways and air routes which link it to both foreign and domestic destinations. It is the starting point of inter-regional highways reaching Nampo, Wonsan and
