The Samoa Electric Power Corporation conveys its sincere apologies to all our valued customers, businesses
and partners for the power blackout on Monday evening, 2nd November 2020, experienced by the whole of
the Upolu Island at exactly 5.28pm.

We also wish to apologise to our valued customers for the delayed information on the Blackout. Given the
need to thoroughly investigate the cause of the blackout, the prolonged release of the information below
is to assure all data obtained is accurate and sufficient for our general public’s information and to make
sure the Corporation puts in-place appropriate measures, to rectify the problem from happening again.

The Blackout was caused by the LOSS OF GENERATION capacity from our Lalomauaga hydro power station.
This rapidly escalated into supply-demand imbalance and eventually led to total system collapse.

The event began when Lalomauga Hydro tripped from a technical fault causing loss of power generation
from Lalomauaga and Taelefaga hydro stations. The two online Fiaga generators responded to recover the
loss of power supply but all reached full load capacity and unable to sustain system stability.

EPC continue to review its protection coordination to make sure we can identify and isolate areas under
fault condition as quickly as possible.

Power however, was restored for the whole of Upolu by 7.48pm on Monday evening.

Again we apologize for the inconvenience caused and we thank the public for its patience and continuous
support while EPC worked to restore power to all businesses and homes.
