Statutory Reports Power Mech Projects Limited Annual Report 2025-26 Company Overview Financial Statements About Us Customer Focus Built by Us. Run by Us. From the first foundation to the last megawatt, Growth and Excellence all solutions under one roof. Performance Building an asset and running it are usually the work of two different companies. At Power Mech they are one. We erect the boiler, turbine and generator, build the civil works that carry them, take the balance of plant on turnkey terms, and are still on site years later operating, maintaining, and overhauling the plant. In mining we have gone further upstream still, to the coal itself. Our values We can hold that much of a site because we perform it ourselves: more than 300 cranes of our own, a fabrication facility at Noida, in-house commissioning engineers and a workforce of around 40,000. The critical path stays with us, and so does accountability for every interface on it. Innovation and Continuous Over the past two and a half decades, we have expanded our capabilities beyond power. Steel, cement and refineries; railways, Safety Improvement metro, and roads; and now coal and mineral extraction, across India and selected international markets. What connects them is not the sector but the requirement: heavy equipment installed to tolerance, structures built to carry it, and systems kept available under contract in places that cannot be switched off. Twenty-seven years of that work is what qualifies us for what comes next: purpose-driven growth without losing sight of the foundations on which our journey has been built.
