Statkraft Norfund Power Investment Group and Aboitiz Power (SNAP) awarded us the Maris South Canal Hydro Electric Power (HEPP) project - an 8.5 MW low-head hydroelectric power station in North Luzon, Philippines.

The award is built on our 10-year working relationship with SNAP, who are the owners of the Ambuklao Hydro Power Plant in the Philippines, which we rehabilitated for them.

The Maris South HEPP is a 'run-of-river' plant located on one of the downstream canals of the Maris Reservoir. The station utilises 2 x 4.25 kW Kaplan turbines.

Our scope of work included the construction of:

  • Upstream and downstream cofferdams
  • Large intake and headrace structures
  • A 21 m high reinforced concrete powerhouse structure housing the turbine units/generators and ancillary equipment
  • Tailrace canal and irrigation diversion canal
  • Design, fabrication, and installation of hydromechanical steelwork
  • Design, construction, installation,n and commissioning of building-related equipment and Balance of Plant

A follow-up contract for new regulating gates was awarded to us due to the success of the Maris South Canal HEPP contract.

The Maris Reservoir water level is controlled by 32 gates installed on the dam crest. The project involved installing mechanical and electrical controls on some of these gates, allowing more control of water levels and thereby better-managing spills and water flow into the Maris South HEPP.
