The original contract for the gas-fired plant was signed in February 2014 and marked the first power pact between a US company and the government of Myanmar following the lifting of sanctions.
The Kyaukse power plant is located south of Mandalay, the second-largest city in a country where nearly 42 mill ion people have no access to electricity.
The turnkey facility was installed in 90 days and is one of the largest thermal plants in the country, providing enough power to serve more than six million people.
After initially commissioning 82 MW in April 2014, APR installed an additional 20 MW at the start of this year to help offset the reduction of hydropower during the annual dry season.
APR chief executive Laurence Anderson said: “We are excited by the continued opportunity to help power the development of one of Southeast Asia’s fast-growing economies.
“As the first US power company to do business in Myanmar in recent years, we have been fortunate to have exceptional business partners in Myanma Electric Power Enterprise and the national government. They have been fully committed to the success of this project and the role it is playing to enhance the quality of life for people in Myanmar.”
