Impact on the Long Island
Electrical Infrastructure
Hurricane sandy was a devastating storm, affecting the
entire atlantic coastline of the united states from florida to
maine and spreading into the mid-atlantic, ohio Valley, and
Great Lakes states. at least 159 people were killed in the
united states. among coastal states, 69 power plants and
102 electric substations were located in areas flooded due
to storm tides. in the service territory of the Long island
Power authority (LiPa), the subject of the study discussed
here, damage occurred to 51 substations (12 were flooded);
nearly 2,500 transformers were repaired or replaced, more
than 4,400 distribution poles were repaired or replaced, and
more than 400 mi of wire was repaired or replaced. this
damage caused a loss of electric service to more than 90% of
LiPa's 1.1 million customers, and it took days and in some
cases weeks or longer to restore their power. LiPa's repair
costs in the days and weeks following sandy approached
us$1 billion.
the response of public officials and electric utilities to the
damage inflicted by sandy has included both near-term and
longer-term measures to increase the resilience of the utility
infrastructure in the affected areas. for example, in october
2013, Governor andrew m. cuomo of new york announced
that approximately us$72 million in federal funding would
be dedicated to helping Long island's electric grid become
more resilient in the event of major coastal flooding or severe
storms by elevating as many as 32 coastal substations in
flood-prone areas. utilities in the hardest-hit areas have identified several billion u.s. dollars' worth of investments that
will be made to harden the grid and increase its resilience to
future storms.
