On January 24, Prime Minister Zandanshatar Gombojav inspected how the Thermal Power Plant No. 4 (TPP-4) State-owned Enterprise operates under a state of readiness.
The TPP-4 alone supplies 58 percent of Ulaanbaatar’s total electricity demand. Operating eight boilers, the plant generates 680 MW of power per hour. However, damage to one boiler created an unavoidable need to impose restrictions.
A rapid response team of 15 specialists and engineers carried out repair works to reconnect the boiler. Nevertheless, General Engineer Boldbaatar D. noted that such emergency repairs are merely a “firefighting measure.” Without reserve capacity in electricity and heat production, there remains a risk that restrictions could recur. For this reason, he emphasized the urgent need to construct a ninth boiler.
The feasibility study for the new boiler was approved two years ago. With nine boilers in operation, the plant would not only ensure the reliability of electricity and heat supply but also have reserve equipment, significantly reducing the risk of outages. It would also enable maintenance and repairs on other boilers, among other advantages.
