Armenia’s power sector has suffered many setbacks: in the late 1980s an earthquake that took its major nuclear plant off-line, and in the early 1990s the collapse of the Soviet Union, economic blockade, and repeated sabotage of a new gas pipeline—all of which severely disrupted fuel supply. Technical and commercial problems further crippled operations. Armenians endured hard winters with barely two hours of electricity a day. The government set out to reform and privatized the sector, persevering through setbacks and learning from initial failure. Its persistence paid off: today the system runs efficiently and delivers power 24 hours a day.
