BUILDING RESILIENT FACILITIES

Conceptual Framework Towards Adaptive Resilient System

COMPREHENSIVE RESILIENCY PLAN:

Ecosystem-Based Approach

Critical Resource Resiliency Planning

Identify vulnerable resource input; restore ecosystem/natural

defences; monitor ecosystems

Disaster Risk Management

Identify Emergency Response, early warning, preparedness

and preventive measures

Climate Change Adaptation

Identify adaptation Options: engineering measures and

natural solutions

Critical Infrastructure

Resiliency PlanningIdentify and reduce business

vulnerability

CLIMATE CHANGE & NATURAL HAZARDS

Critical Infrastructure Resiliency Planning

Vulnerability Assessment of Project Facilities

Comprehensive Resiliency Management Plan for BacMan Geothermal

Facilities

Critical Infrastructure Resiliency programs have been identified.

Vulnerable Facilities of Bacman Geothermal Project has been identified and mapped-out.

Critical Infrastructure Resiliency Planning

OBJECTIVESDetermine and Identify the level of vulnerability

of EDC’s critical infrastructures including

its immediate environment to climate and change and major hazard and its effects;

Assess existing coping mechanisms (if any) to climate change hazards

and propose appropriate strategies for adaptation and/or mitigation of the

hazards; and

Enhance EDC’s technical knowledge to better

understand and make use of climate information, and enhance relevant

data and access to data for planning and decision-

making.

Reliability Typhoon Survivability

• Palayan generator life extension assessment

• Auxiliary equipment improvement• Hot well pumps• CW discharge valves• Auxiliary CW pump redundancy

• Restore cooling tower N+1 capability

• Replacement of legacy and obsolete 230KV switchyard tie breakers

• Future improvements

• Cooling tower• Installation of RTM fan stacks• Design for 300 kph gale winds

• Restored facilities to withstand 300 kph winds

• Install geotechnical instrumentation on all critical slopes

• Design and implement long term mitigation measures on critical slopes / access road

BGBU HAS THREE (3) EXPANSION PROJECTS WHICH ARE IN VARIOUS STAGES OF DEVELOPMENT

THANK YOU!

Plan for SustainabilityProjects should be designed so their impact continues long after the company’s involvement. Projects that focus on developing community skills and capacity or improving community incomes yield more sustainable benefits than projects and programs that simply distribute goods and services. Companies can plan for sustainability with communities by building community capacity to manage projects and encouraging links with other organizations. Companies should prepare to hand over responsibility for projects to communities, governments or other organizations once the program has become sustainable and self-sufficient. Setting a timetable to hand over responsibility with measurable goals and benchmarks is essential to avoiding dependency.
