ContourGlobal Maritsa East 3 TPP Completes the Annual Facility Maintenance

ContourGlobal Maritsa East 3 TPP has completed the annual maintenance of its four power units and is ready to operate at full load. The maintenance activities, for which external contractors were also engaged, were organized under the strictest safety requirements for equipment, processes and people.

“As one of the largest industrial capacities in Bulgaria, which operates entirely with local resources, our power plant is a major vital element of the country’s energy system. We know that in the winter season, when more energy will be needed at socially affordable prices, our continuous work will be of extreme importance, and for this reason we maintain the equipment in excellent condition. Now, the power plant is fully ready to operate at its full potential and meet the needs of electricity on the Bulgarian market”, explained Eng. Alexander Zhelev, Chief Engineer at ContourGlobal Maritsa East 3 Thermal Power Plant.

The annual scheduled maintenance of the ContourGlobal Maritsa East 3 thermal power plant started at the beginning of June. The facility maintenance ensures the efficient and safe operation of the power plant during the autumn and winter seasons, when loads are usually greater due to low temperatures and high electricity demand. Dozens of external companies-subcontractors and over 1,000 of their own staff took part in the maintenance on the territory of the TPP, as well as engineers and experts from ContourGlobal.


ContourGlobal Maritsa East 3 owns and operates the first lignite-fired thermal power plant in Southeast Europe, which operates in full compliance with the highest European standards for labor safety and environmental protection. The power plant generates approximately 10% of the electricity in Bulgaria, using local energy sources and thus contributes to guaranteeing the energy security and independence of the country. More than BGN 1.4 billion have been invested to guarantee the reliable operation of the power plant and in meeting environmental protection and occupational safety standards. The shareholders are the international energy company ContourGlobal (73%) and the National Electric Company (27%).
