Using precision measurement and digital modeling to restore hydro equipment to OEM-level accuracy.  Rebuilding aging hydro components requires data you can trust. Modern 3D scanning and reverse engineering allow engineers to capture exact geometry, recreate missing drawings, and validate fit before manufacturing. Originally presented at the Innovation Powerhouse at Clean Currents 2025, this article highlights how these technologies bridge the gap between legacy components and new precision parts—driving performance improvements in turbine refurbishment and hydro plant modernization.  Aging Infrastructure & Limited Documentation Many hydroelectric plants in operation today were constructed decades ago. Over time, mechanical wear, corrosion, [...]

The Critical Role of Precision Machine and Component Alignment in Power Generation

By |2026-02-02T14:00:31-05:00September 25, 2025|Articles|

When it comes to keeping power generation facilities running efficiently, alignment accuracy is critical. While our colleagues at OASIS Alignment Services specialize in laser tracker-based alignment inspections, Exact Metrology supports these efforts with advanced 3D scanning and long-range scanning. By capturing high-resolution data and creating detailed digital models, we help engineers reverse engineer legacy components, validate alignment, and perform virtual fit-ups before outages. In traditional power generation - coal, gas, nuclear, & hydropower - the performance and reliability of critical equipment hinge on precision alignment. Turbines, generators, pumps, compressors, and other rotating assets operate under immense loads and at high speeds. Even a [...]
