Senators, on Tuesday, waited helplessly on the Abuja Electricity Distribution Plc to restore power supply before the commencement of sitting.
The development plunged the Red Chamber into partial blackout as the lawmakers groped in the dark.
President of the Senate, Godswill Akpabio, would later commence plenary after power was restored some minutes later.
The Abuja Electricity Distribution Plc, in February, threatened to disconnect the electricity supply of 86 Ministries, Departments and Agencies (MDAs) over a total debt of N47.1billion.
Some of the MDAs include the Ministry of Finance, Information, Budget, Works and Housing, barracks, Nigeria Police Force, Presidential Villa, CBN Governor, Economic and Financial Crimes Commission (EFCC), Federal Inland Revenue Service (FIRS), Federal Airports Authority of Nigeria (FAAN), and state liaison offices in the Federal Capital Territory (FCT).
