Gugler Water Turbines gives a tour of some of the hydropower projects it’s been working on worldwide
IN MARCH 2025, THE Haut Fournel Hydropower Plant in France became fully operational, utilising Gugler’s Francis turbine technology. Here the company supplied: Turbine I – 746kW, 1.39m3 II – 372kW, 0.70m3
/sec, 480mm runner diameter; Turbine /sec, 380 mm runner diameter.; Both
turbines operate with a head of 58.75m. In June, the 1.68MW Kumu Hydropower Plant in Guyana was commissioned successfully. Following restoration of the 0.79MW Moco Moco plant in December 2024, these back-to-back turnkey projects now provide over 2MW of renewable power to meet Region Nine’s demanding high-head, low- flow conditions. Both Kumu and Moco Moco were delivered under Vidullanka PLC’s EPC contract with the Guyana Energy Agency.
Originally commissioned in 1999, the Moco Moco
plant was damaged by a landslide in 2003 and had been out of service until the end of last year. Following its rehabilitation, the plant is now fully operational, with its capacity increased from the original 0.5MW to meet the region’s growing energy needs. Located on the Moco Moco Creek, this plant features a high net head of 206.9m and a flow rate of 0.22 m3
/
sec. The plant operates with two Gugler horizontal Pelton turbines, each designed for high efficiency in challenging conditions, running at 1200 rpm, and now providing reliable, renewable energy to the Lethem area. At the Kumu plant, Gugler’s scope of supply included a Pelton turbine (0.36m3/sec), generator, flywheel,
HPU, inlet valve, control and protection equipment, switchgear, the auxiliary supply system, and SCADA. A recent 24 hour trial saw Kumu and Moco Moco meet Lethem’s entire electricity demand with hydropower alone and annually they’ll be generating around 14,200MWh. Along with a local 1MW solar farm, Region Nine’s clean energy portfolio is helping to advance Guyana’s pillars of energy, food, and climate security. “This project is not just about electricity,” Prime
Miniter Mark Phillips said during the official commissioning of Kumu in July 2025. “It’s about building a platform for progress – supporting businesses, creating jobs, strengthening public services, and improving quality of life.” Indeed local benefits of the two hydro projects include creating 20 jobs, providing stable power for schools, clinics, and agro processing; plus extended study hours via the internet

In Peru, Gugler has also worked on the Anashironi hydropower plant. This new facility marks a major expansion of the existing Renovandes H1 plant, adding an entirely new turbine-generator unit that operates as an independent hydropower station under the name Anashironi.
