The Nigerian Electricity Regulatory Commission (NERC) has announced a 45-day deadline for the registration and authorisation of grid-connected private transmission substations under Order NERC/2026/013.
In a public notice, NERC noted that the deadline took effect on March 9, 2026, as part of efforts to strengthen oversight of privately owned substations connected to Nigeria’s national grid.
The Commission explained that the order establishes a regulatory framework requiring owners of private transmission substations used by bulk electricity consumers to obtain an Independent Electricity Transmission Network Operator (IETNO) permit before operating or connecting to the grid.
“The directive was introduced to improve grid reliability, safety, and operational visibility following frequent transmission line trips reported by the Nigerian Independent System Operator (NISO).
“Under the Order, NISO must submit to NERC a comprehensive list of all existing Private Transmission Substation Owners (PTSOs) and notify them of the provisions of the Order within five (5) days. Existing PTSOs must apply to NERC for an IETNO permit within 45 days,” it said.
The Commission also directed new PTSOs to obtain the permit before connecting to the grid, warning that non-compliance will attract regulatory sanctions.
NERC disclosed that NISO will deploy IoT-based metering systems at substation interconnection points within 120 days, stressing that operators are required to submit monthly operational reports, while NISO will conduct inspections to ensure compliance.
It added that the order aims to enhance grid stability, strengthen regulatory oversight, and ensure compliance with the Grid Code in the Nigerian Electricity Supply Industry.
