Munich, Germany—In the midst of increasingly urbanized
Philippines and calamitous extreme-weather-related disasters that
frequent its urban centers, national and local governments and
planners are now acutely aware of the many challenges in providing
urban sustainability. Many of them have undertaken extensive
disaster planning and worked on elaborate rapid response systems.
Dedicated city disaster management teams have also been working
around four key areas: risk reduction, preparedness, response, and
recovery. But more needs to be done, especially in the oftenoverlooked strategies for improving urban energy system resilience.
They could be made more resilient by introducing options that
decouple these systems from the central power grid. Microgrids
provide options.
Most disaster plans, however, are focused on strengthening existing
large-scale power networks. This means that in the Philippines,
bringing back power postdisaster entails months of rehabilitating the
grid. Resilient energy systems in the age of wrenching change means
disaggregating them—not just shoring up centralized, large-scale
energy infrastructure.
In the urban setting, disaggregation calls for veering away from this
monolith and, instead, moving toward exploiting the opportunity of
local generation and storage and smart microgrid. Disaggregation
helps ensure that critical infrastructure, such as disaster command
centers and evacuation areas, will continue to have power postdisaster. To do this, we need to move toward site-specific urban
energy systems. The source of energy must be more local. The system
must be responsive to local needs. Blending these energy systems
with lower carbon objectives is also necessary.
To accelerate progress in establishing resilient and sustainable urban
energy systems, several steps can be taken, and may require new
approaches. National and local disaster planning authorities should

support and embark on a project that reach out more intensively to
the distributed energy, storage, and smart grid production chains.
A simple representation of this system can be visualized as follows:
Some solar rooftop PV and wind renewables are installed and tapped
to generate community electricity. With some storage support from
batteries and a backup diesel genset, they are then connected
together in a microgrid that can then be remotely monitored and
controlled.
We also need new tools and methods of analysis to know how
resilience and adaptive capacity of our urban energy systems can be
optimized. Postdisaster, for example, some neighboring microgrids
may need backup. This gap can be filled by a nearby microgrid
system.
Innovative financing will also be necessary. Suitable mechanisms
need to be designed, such as cross-subsidies where conventional
electricity is levied to provide a direct subsidy to sustainable
microgrids. Subsidies of this kind, at any rate, should be resultsbased and need to be linked to some form of equity capital.
While some technologies are in place to support the objectives and
strategies of resilient and sustainable urban energy systems, more
awareness-raising remains imperative. As ordinary Filipinos become
energy producers and participate in a mini-electricity network, some
forms of capacity strengthening are necessary to help them
understand this new role.
Such responsible citizenship is also required to ensure the resiliency
and sustainability of our urban energy systems as they keep up with
the growing challenges of climate change and the shift toward an
increasingly urbanized Philippines.
