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, [...]
