Hydro service and rehabilitation in USA

ANDRITZ has refurbished seventy hydropower units in the United States representing about 54% of fleet share of the countries total installed capacity.

Innovative modernization measures increase the profitability and lifespan of hydropower assets. Services of the company range from operation and maintenance, to long-term optimizations as well as digitalization and automation. Repairs and spare parts deliveries are also part of the portfolio.

Key Highlights

John Day Lock

ANDRITZ was awarded a contract for the upgrade of the Kaplan turbine hubs of the John Day Lock and Dam hydropower station, in the northwest of the United States of America. ANDRITZ will disassemble the entire turbine-generator unit, repair the Kaplan runner on-site, replace as needed wearing components, install new runner hub internals, refurbish as-required mechanical components off-site, reassemble the unit, and perform testing and commissioning after the installation. Following the repair, all the runners under the contract will function as double-regulated Kaplan runners.
