Just over 25,000 customers were suddenly without power Tuesday after a tree fell on Y103, a power line bringing electricity to all of P.E.I.
Just after 3 p.m. there was a dip in power that startled people across the Island but for some, the power simply went out in parts of Summerside and areas west to Tignish, plus Stratford and areas East towards Montague.
Charlottetown was unaffected by the disruption.
Maritime Electric had to fire up local generator systems as it searched for the cause, said a Maritime Electric spokesperson.
The New Brunswick power cable comes ashore at Richmond Cove on P.E.I. and from there big power lines take the electricity to the Bedeque substation where it gets distributed to the rest of the Island.
One of those big overhead power lines from Richmond Cove to Bedeque is called Y103 and a tree fell over on that line, said the spokesperson.
Crews had the situation fixed and power restored to most locations within 40 minutes.
In the meantime, power suddenly went out in the Hunter River area from about 4:20 to 5:50 p.m. affecting some 3,700 customers, likely due to the switching between on-Island generation and restoring power from the cable.
