DAUIS, Bohol – Typhoon “Ruby” that brought fears and destruction in several provinces, including Bohol, has taken toll on the power supply in the province that largely relies on Leyte’s geothermal. As a consequence, supply of water from the aquifers in Corella town generated by the electricity is also adversely affected, reports said. The report said that residents of at least two barangays — Totolan and Songculan of this town — raised a howl since no drops of water come out from their faucets for days now since the typhoon “Ruby” stormed Leyte and neighboring provinces. Bohol Water Utilities Inc. (BWUI) that provides water supply in some barangays here said that pumping units 2 and 5 can hardly supply water and bring it to reservoirs because power supply tripped off at times. For two days already, power supply in the city is also affected and became intermittent as if there’s rationing going on, according to a resident.
It was not immediately known if Bohol Electric Cooperative I that servicing Corella town has a ready solution or measure on this predicament.
Power blackout has practically crippled business establishments in the province two days ago as a result of the typhoon “Ruby.”
Earlier on, the National Grid Corporation of the Philippines (NGCP) released a power advisory that it “is coordinating with Leyte power plants, which went offline around 9 AM today, for the supply to be transmitted to Bohol via Maasin 138KV –Maasin-Ubay submarine cable.” Power interruption in Bohol “after 138 KV Ubay-Maasin line was isolated by UFR (Under Frequency Relay) activation,” NGCP said.
“UFR is part of an automatic scheme to maintain system balance when significant changes occur to the grid such as the present unavailability of geothermal power plant in Leyte which was affected byheavy rains,” it added.
It will be recalled Bohol has experienced blackout for weeks following the magnitude 7.2 earthquake that struck the province on October 15, 2013, leaving scores of deaths and havoc on infrastructure, private properties, public buildings and important cultural heritage.
A combined power of three hydro power plants in Loboc, Sevilla and Balilihan and Bohol Diesel Power Plant (BDPP) based in this city can only supply around 22 MW. It needs around 68 MW enough to supply the power requirement.
