Delivering Value

Through our Natural Catastrophe (NatCat)  Resiliency Framework, we completed 24 targets  for 11 Landslide Mitigation Projects, six Typhoonproofing Projects, two Cooling Tower Replacements,  and five sites implemented with Forest Fire Control  Measures. We ensured this level of safety and  resiliency were observed in all our sites by following  the NatCat framework supervised by the NatCat  Site Technical Teams. In promoting timely and  accurate information dissemination critical to our  operations, we implemented SMS alert notifications.  These equipped our teams with better weather  forecasts and met, slope, and earthquake data.  Through these initiatives, we enhanced our capacity  to prevent prolonged outages and safety incidents  due to natural catastrophes such as typhoons,  landslides, earthquakes, and forest fires.  

Our manufactured capital generated a total  energy of 7,490 GWh. We further strengthened  this through improved equipment reliability and  availability, effective asset management practices,  increased generation resulting from high and  low-pressure steam segregation, and enhanced  efficiency from regular monitoring and preventive  maintenance. We also expanded our generated  energy from reduced plant consumption of auxiliary  steam (hybrid GRS) and the significant increase  in ancillary service revenue resulting from control  system upgrade compliant to AGC (Automatic  Governor Control).  

Further, our explorations and drilling of new wells  provided us with additional steam capacity, while  the upgraded cooling structures improved plant  availability and enhanced our facilities’ typhoon  resiliency.  

Equipment upgrade and adoption of new  technologies remain a priority in our geothermal  resource, along with initiatives to add revenue  and improve our efficiency in power generation.  In our geothermal reservoirs, we optimized  geothermal resources by developing new pads  and Fluid Collection and Recycling System (FCRS)  interconnection. We also conducted Technical  Due Diligence in various local and international  geothermal assets for possible acquisitions or joint  venture opportunities.  

EDC made significant progress on its binary plant  projects, with both the 29MW Palayan Binary Power  Plan (PBPP) and Mindanao 3 (M3) binary plant  commencing site work in 2021. As evidence of our  commitment to upholding rigorous safety standards  across our sites, the Palayan plant recorded 1  million safe working hours. The Mindanao plant  noted 500,000 safe working hours without a losttime incident as of December.  

The 20MW Tanawon geothermal power plant  was awarded a grant from the Joint Crediting  Mechanism (JCM) of Japan amounting to JPY1.6  billion (PHP 640 million) in September 2021.  Throughout the year, the Tanawon plant project  underwent contract negotiations for contractors and  gained conditional approval before finally being  endorsed by Sorsogon City in December.  

Lastly, the 36MW Mahanagdong geothermal  brine optimization plant gained approvals from the  Department of Environment and Natural Resources  (DENR) and National Grid Corporation of the  Philippines (NGCP) for its ECC and facility study.  Its brine nomination has been confirmed at 500  kilograms per second.
