Mr Godwin Idemudia, Assistant General Manager, Public Affairs, EKEDC, made the apology in an interview with the News Agency of Nigeria (NAN) on Tuesday in Lagos.
Idemedia said that the power outage was due to faulty cables that supply electricity to the area.
He said that engineers from EKEDC were repairing the fault and assured the affected consumers that electricity supply to the area would be restored soon.
He urged the consumers not to vandalise the EKEDC equipment in their communities because of the outage.
Meanwhile, some operators of relaxation spots within the National Theatre complex have said that the power outage had impacted negatively on their businesses.
They told NAN that they have spent about N250, 000 on diesel used to power their electricity generator.
One of the operators, Miss Bola Ogunsakin, said that most of their customers had deserted the place due to power problem.
Ogunsakin said that their profit margins had dipped drastically following the N2, 000 they contribute daily to purchase diesel.
“This has even made some of our customers to desert the relaxation centers built under the tree.
“We are appealing to EKEDC to restore electricity supply to National Theatre before things get out of hands,’’ she pleaded. (NAN)
