LIPA restores electric service faster than any other utility in the state. The total annual power outage time for Long Island customers has been the lowest among New York State utilities using overhead power lines for 10 of the past 12 years.
The LIPA Restoration Team
Our entire work force is put to work if a major storm hits.
Our work force is specially trained to respond to storm
emergencies and are prepared to work around the clock, seven
days a week, to restore your service.
Nearly all of our employees turn from their regular jobs to help restore electricity to our customers. We also bring in workers from neighboring utilities and contractors to supplement our crews and speed up the repair effort. - Learn more
LIPA Ranked Most Reliable Overhead System in NYS
For the 4th consecutive year, LIPA's transmission and
distribution system continues to be ranked among the best in
New York State. LIPA has earned this distinction by
attaining the top ranking for quickest time for restoration
of service and shortest average duration of outages, and
being ranked among the top 2 NYS utilities in longest
frequency between service interruptions. In developing its
award winning reliability track record, LIPA has invested
approximately $2 billion in reinforcing and upgrading its
transmission and distribution system since 1993.

Customer Care Center
We can mobilize up to 300 employees to staff our telephones at a centralized Customer Assistance Center. These operators can
handle thousands of calls an hour. During a severe storm, when
there is a large amount of calls coming in at the same time, we
now have automated service that can log your outage.
Circuit Improvement Programs
LIPA surveys hundreds of miles of electric lines annually to
identify and correct any substandard line conditions,
restore or replace deteriorated poles, replace deteriorated
underground and over head cables, and install lightning
arrestors and animal protection devices.
Automatic Sectionalizing Units
LIPA installs “smart switches” on its overhead electric
circuits to automatically isolate downed or faulted wires
and maintain electric service to approximately one-half of
the customers supplied from the associated circuit. System
Operators can remotely control these switches to rapidly
restore service and re-route power to minimize customer
outages.
CAIDI, MAIFI and SAIFI
These terms are important measurements or
indices of LIPA’s performance.
CAIDI -
Customers Average Interruption Duration
Index
MAIFI - Momentary Average
Interruption Frequency Index
SAIFI - System Average
Interruption Frequency Index
CAIDI measures the average restoration time, or how long it takes LIPA to re-establish electric service should there be an outage. In 2005, LIPA’s CAIDI was 64 minutes.
MAIFI measures “momentary” interruptions. How long is a momentary interruption? Usually less than five minutes.Last year, LIPA’s MAIFI remained at 4.9; the best since 1996, when we began to keep statistics.
SAIFI measures the length of time between service interruptions. In 2005, LIPA’s average SAIFI was 14.1 months between interruptions. This means that a large portion of our customers have not lost power in over a year!
Forestry Program
Most service interruptions result from tree limb contact
with electric wires. We are dedicated to providing Long Island with a safe,
reliable supply of electricity. To do this, we have a number of proactive
programs that help reduce electric outages and improve safety. One of our
most effective programs in this area is our Forestry Program. This includes
removing trees that interfere with power lines and replacing them with
shorter “wire friendly” trees reduces the likelihood of tree or branch
contact.
