Poyry, a global consulting and engineering firm based in Finland, has been awarded a EUR 6.1 million (US$8.3 million) contract for feasibility studies, tender design, detail design and construction supervision of the Uma Oya hydropower project in Sri Lanka.
The EPC (engineering, procurement, and construction) contractor for the whole project is FARAB International of Dubai (UAE).
The project comprises two dams and over 15 kilometers of water conveyance tunnels, a 700 meter deep shaft and an underground powerhouse with two Pelton turbines of 150 MW installed capacity. Poyry will start the study work immediately and the design phase will be completed by end 2011, Poyry reported.
The main construction activities are scheduled to start in early 2011. The power station will be commissioned in early 2016.
The construction of the hydropower plant and the dams is part of a wider Uma Oya Multipurpose Development Project by the Ministry of Irrigation of Sri Lanka. The project combines the hydropower schemes and irrigation in a sustainable way.
In the project, water will be diverted from the wet central highlands into the dryer southern part of Sri Lanka for irrigation and human consumption and will use the available head of over 700 meters for energy generation.
During the past 30 years, Poyry has made a major contribution to development of hydropower in Sri Lanka by engineering four major hydropower schemes, the company reported.
