19/04/2024: New Zealand Hydropower Group Conference in Hamilton
Exciting news from the New Zealand Hydropower Group Conference in Hamilton! ANDRITZ Hydropower proudly served as the gold sponsor for this event on 10th – 11th April 2024, with some 130 attendees joining together for two days of presentations and networking.
Attendees of the Karapiro hydro station site visit, hosted by Mercury NZ and ANDRITZ, gained insights into our major refurbishment project, including our cutting-edge 100% water-lubricated Kaplan solution. Werner Ladstätter, our Technology Manager for Generators from Austria, shared invaluable research on partial discharge in modern mica insulation systems, sharing important information to shape future procurement specifications and assess generator life.
Our General Manager in New Zealand, Tony Mulholland, contributed to a dynamic procurement panel discussion with other visionary panellists, highlighting industry challenges, changes, and future trends. A big thank you to everyone who attended the conference and visited our booth - we anticipate more engaging interactions next time!

Mid-March 2023, we have installed the rotor in Unit 2 at Karapiro Hydro Power Station, on the Waikato River in New Zealand.
With the stator, thrust bracket and water lubricated runner hub already placed we’re in good position for final assembly and commissioning.
Congratulations to the entire ANDRITZ and @MercuryNZ teams for the excellent collaboration!

02/12 2022: Karapiro, New Zealand – 30 tons of steel
At Karapiro, New Zealand the ANDRITZ and @Mercury team have reached a major project milestone, with the first new piece, the runner chamber and bottom ring being lowered into place for test fit.
This has approximately 30 tons of stainless steel and will be aligned and levelled to fractions of a millimeter by the specialists at ANDRITZ before being welded to the existing draft tube liner and then concreted in place.

08/03 2022: Tekapo B, New Zealand - Turbine upgrade project installation complete
The last turbine at Tekapo B has been commissioned in February 2022 and has recently successfully completed its endurance run.
ANDRITZ is proud to have delivered another high efficiency turbine to a New Zealand customer.
At the end of 2016, ANDRITZ was awarded a contract for the refurbishment of the Tekapo B hydropower plant located at Lake Pukaki at the end of the Tekapo Canal in the South Island, New Zealand. The plant has two vertical Francis units with a combined capacity of about 160 MW. The owner, Genesis Energy, is one of the largest electricity generators and retailers in New Zealand. It owns a generation fleet comprised of thermal, hydro and wind generation, with a total MW generation capacity of 1,651 MW.
The upgrade significantly improves the efficiency of the turbine, reduces maintenance and complexity by eliminating the relief valve and has significantly improved hydraulic stability and vibration of the machine. The installation works included installing the new turbine parts, maintenance works on the generator stator and rotor, and repair of the retained parts.
This is another major project completed by ANDRITZ's installation team in New Zealand and has again demonstrated our commitment to partnering with our customers to deliver a high-quality machine assembly in the challenging COVID environment.
