Gugler Water Turbines GmbH is thrilled to announce the successful commissioning of the 1,68 MW Kumu Hydropower Plant in early June 2025. This achievement was formally marked by Prime Minister Mark Phillips and GEA CEO Dr. Mahender Sharma on July 11, 2025.
Following the restoration of the 0,79 MW Moco Moco plant in December 2024, these back-to-back turnkey projects now provide over 2 MW of precision-engineered renewable power, expertly tailored to Region Nine’s demanding high-head, low-flow conditions. These projects were delivered under Vidullanka PLC’s EPC contract with the Guyana Energy Agency.
Kumu showcases our horizontal Pelton technology, which is crafted for peak efficiency and reliability, and it reinforces Gugler’s reputation for overcoming logistical and environmental challenges in remote hydro installations. Our role as a trusted partner in Guyana’s transition to a stable, clean-energy future is being cemented together with Moco Moco and Kumu projects.
Technical Highlights
Flow rate: 0,36 m³/s
Net head: 523 m
Installed capacity: 1,68 MW
At the heart of the Kumu plant is our horizontal Pelton turbine, which is paired with a directly coupled generator and a precision-balanced flywheel. This setup converts a 523 m net head and 0,36 m³/s flow into 1,68 MW of clean power. GUGLER’s scope of supply included the Pelton turbine and nozzle assembly, generator, flywheel, hydraulic power unit and inlet valve, along with comprehensive control and protection equipment, switchgear, SCADA and auxiliary supply systems. After the factory acceptance testing and on‑site commissioning, performance tests confirmed the installation exceeded its guaranteed efficiency.
-
Turbine & Capacity: 1,68 MW horizontal Pelton runner directly mounted on the generator shaft
-
Hydraulics: 523 m net head | 0,36 m³/s design flow
-
Output & Efficiency: ~9 700 MWh/year at > 90 % efficiency
-
Delivery: Completed ahead of schedule and within budget
With Kumu (1,68 MW), Moco Moco (0,79 MW), and a 1 MW solar farm, Region Nine’s clean‑energy portfolio reaches 3,47 MW – advancing Guyana’s pillars of energy, food, and climate security. Prime Minister Phillips praised this diversified mix of hydropower, solar, and gas‑to‑power as key to lowering costs and expanding access nationwide.
“This project is not just about electricity,” said Prime Minister Phillips.
“It’s about building a platform for progress—supporting businesses, creating jobs, strengthening public services, and improving quality of life.”
A recent 24‑hour trial saw Kumu and Moco Moco meet Lethem’s entire demand with hydropower alone. Demonstrating both technical resilience and profound community impact.
