ABUJA, Nov 29 (Reuters) - Nigeria's national electricity
grid collapsed on Sunday, the Transmission Company of Nigeria
(TCN) said in a statement.
Power outages in Nigeria, the most-populous nation in
Africa, are common, but a system collapse is unusual.
"At 11:25am today, the nation's electricity grid experienced
multiple trippings, which led to the collapse of the system,"
the company said in a statement.
"TCN has since commenced grid restoration; power has been
successfully restored to every part of the country, except
Calabar, Ugwuaji, Makurdi, Jos, Gombe, Yola and Maidugiri axes,"
it added.
TCN said it would conduct investigations to establish what
caused the "multiple trippings" as soon as the grid was fully
restored.
The nation's sclerotic power grid, along with the resulting
precarious energy supply, is a key issue hindering growth in the
continent's largest economy.
Nigeria recently implemented its first power tariff increase
in state-controlled prices since 2015. That doubled prices for
some consumers, but the government and industry said it was
needed to allow distribution companies to recoup costs and pay
generating companies.
