The LTMA with MHPS covers major equipment including boilers, steam turbines and flue gas cleaning systems, built by MHPS. The company has had previous LTMAs of three, six and nine years at the BLCP Power Station.

The comprehensive LTMA includes regular inspections, equipment replacement, and efficiency improvements. The extension concludes in 2032, when the 25-year power purchase agreement with the Electricity Authority of Thailand is completed.


The signing ceremony, held at the MHPS head office in Yokohama earlier this month, was attended by BLCP Managing Director Yuthana Charoenwong and other company executives, with MHPS represented by President Ken Kawai.

The BLCP units burn about 3.64 million tons of coal annually. The station is installed with flue gas desulfurization, electrostatic precipitator, low NOx (nitrogen oxide) burner, wastewater treatment and other environmental management technologies.

Its planning and contract awards date back to theà‚ early part of this century.
