Powerplants open to tours

Hydropower developer Hedcor conducts tours of its facilities to demonstrate how a run-of-river system works. Recently, a group of residents from the municipality of Tinglayan in Kalinga participated in one of the tours. The group visited hydropower plants in Benguet and Ilocos Sur.

Run-of-river is a design scheme for hydroelectric power generation that is least disruptive to the environment. It works by redirecting river water through a weir into conveyance pipes towards a penstock and feeding it downhill to drive a turbine in the power station. Exactly how it works was witnessed first hand by the participants to the tour.

The group toured the 70-MW Bakun AC hydropower plant in Alilem, Ilocos Sur. Then they proceeded to the newly constructed Irisan 1 Hydropower Plant in Tuba, Benguet.

The group was accommodated by Hedcor’s engineers and were shown a complete run through of the run-of-river hydropower plants. Operations were also explained as they went along.

Hedcor will build its first plant in the Mountain Province next year. By January 2013, construction will begin on the 14-MW Sabangan hydropower project.

Hedcor, an AboitizPower subsidiary, is the largest developer of run-of-river hydropower in the country. It has 19 hydropower plants in Benguet, Davao and Ilocos Sur with a total capacity of 155MWs.
