Singapore-based Sembcorp Industries is on time and budget with construction works for the Myingyan combined-cycle gas turbine (CCGT) power plant. Upon commissioning in 2018, the 225MW facility will be the biggest CCGT in Myanmar. It will be run by Sempcorp for 22 years, and then the Government of Myanmar will take ownership.
Located in the in the Mandalay Division of central Myanmar, Myingyan CCGT project is carried out by Sembcorp Myingyan Power Company under a build-operate-transfer (BOT) agreement, signed with the Ministry of Electricity and Energy of Myanmar (MOEE) in January.
Execution of the project is currently being carried out by SDCI, a Sembcorp subsidiary, and Jurong Engineering of Myanmar. The plant ownership is being shared between Sembcorp (80% stake) and its partner MMID Utilities of Myanmar (20%).
Project finance
Costs for the project do stack up to approximately $300 million.
Funding is being provided by the International Finance Corporation (IFC), the Asian Development Bank (ADB) and the Asian Infrastructure Investment Bank (AIIB) as well as international commercial lenders such as Clifford Capital, DBS Bank, DZ Bank, and Overseas-Chinese Banking Corporation.
22-year PPA in place
All electricity produced by the Myingyan CCGT will be supplied to Electric Power Generation Enterprise (EPGE), previously known as Myanmar Electric Power Enterprise (MEPE). Sembcorb on March 2016 sold the entire power output of the 225 MW plant to EPGE under a 22-year power purchase agreement (PPA).
The Greenfield gas power project will be built on a site of nearly 30 acres of land in Taungtha, a township of Myingyan in the Mandalay division of central Myanmar.
Technology from GE, ABB
The high-efficiency CCGT will be powered by two GE F.03 gas turbines, a reheat steam turbine, and two heat recovery steam generators (HRSGs). The exhaust energy of the F.03s, deployed at the plant, allows for midsize combined-cycle operation with a net efficiency of more than 54%, according to the manufacturer. The DLN 2.6 combustion system of the 6F.03 reduces emissions, while its multi-nozzle quiet combustor (MNQC) holds synthesis gas from 20% to 90% hydrogen. It applies steam or nitrogen injection to return less than 25ppm nitrogen oxide (NOx) emissions, GE stated.
Operation of the entire plant will be monitored and fine-tuned by ABB Symphony Plus total plant automation system, integrating SD Series flexible control and I/O modules. To that end, it will make analyse the plant’s operating data and monitor performance.
