The Nigerian Electricity Regulatory Commission (NERC) has directed all privately owned transmission substations connected to the national grid to obtain regulatory permits within 45 days, introducing a formal oversight framework for private transmission infrastructure within Nigeria’s electricity network.
The directive, issued as Order NERC/2026/013 and effective from March 9, 2026, requires operators of private substations supplying bulk electricity consumers to obtain an Independent Electricity Transmission Network Operator (IETNO) permit before operating or connecting to the grid.
The regulator said the measure was introduced following repeated transmission line trips reported by the Nigerian Independent System Operator (NISO), raising concerns about operational visibility and technical coordination within the national grid.
The order also mandates the deployment of Internet-of-Things based metering systems at substation interconnection points within 120 days, alongside monthly operational reporting by operators.
DECISION HIGHLIGHT
The NERC has introduced a mandatory permitting framework for privately owned grid-connected substations, requiring operators to obtain IETNO permits within 45 days.
The order also mandates IoT-based monitoring systems at substation interconnection points to improve grid oversight and operational coordination.
DECISION MEMO
Nigeria’s electricity system has historically operated as a tightly centralised infrastructure network, with transmission infrastructure managed primarily through government-controlled entities.
However, the gradual evolution of the Nigerian Electricity Supply Industry has introduced new forms of private participation, including dedicated transmission infrastructure developed by industrial consumers and private electricity generation projects.
While these private substations often support large industrial facilities or embedded power generation systems, their integration into the national grid has created operational complexities.
The NERC’s latest directive reflects regulatory concerns that these privately owned transmission assets operate with limited visibility within the national grid architecture.
Frequent transmission line trips reported by the NISO have raised questions about coordination between private infrastructure and the national transmission network.
The new permit framework attempts to address this structural gap by formally recognising private substations as regulated transmission network operators.
By requiring operators to obtain IETNO permits, the regulator aims to integrate private infrastructure into the broader regulatory and operational oversight structure of the electricity market.
The introduction of Internet-of-Things based metering systems also reflects the increasing digitisation of grid monitoring systems.
These devices will enable real-time monitoring of electricity flows at substation interconnection points, providing system operators with greater operational visibility across the network.
The directive also introduces compliance reporting obligations, requiring operators to submit monthly operational data while allowing the NISO to conduct technical inspections.
Beyond transmission oversight, the regulator has also issued a separate directive addressing consumer protection within the electricity market.
The NERC recently ordered electricity distribution companies to reimburse N20.33 billion to customers who purchased meters under the Meter Asset Provider (MAP) framework.
The order requires the reimbursement to be completed within 12 months, beginning March 1, 2026, reflecting regulatory efforts to improve consumer confidence in the electricity sector.
Together, these directives illustrate a regulatory attempt to strengthen both technical oversight and consumer accountability within Nigeria’s evolving electricity market.

WHO WINS / WHO LOSES
Grid system operators benefit from improved visibility into privately operated substations and better coordination of electricity flows across the national network.
Industrial electricity consumers using dedicated substations may face new regulatory compliance obligations and operational reporting requirements.
Electricity customers benefit from the regulator’s meter reimbursement directive, which addresses longstanding complaints under the Meter Asset Provider programme.
Private substation operators may incur additional compliance costs associated with permits, reporting requirements and monitoring infrastructure.
POLICY SIGNALS
The directive signals a shift toward stronger regulatory oversight of private infrastructure integrated into Nigeria’s electricity grid.
It also reflects the growing complexity of Nigeria’s electricity market as private generation, transmission and distribution assets increasingly interact with the national grid.
The emphasis on digital monitoring suggests regulators are prioritising data visibility and system transparency as part of electricity market reforms.
INVESTOR SIGNAL
For investors in Nigeria’s power sector, the directive indicates increasing regulatory formalisation of private transmission infrastructure.
While stronger oversight may increase compliance requirements, it could also improve operational stability and reduce system disruptions that affect power projects and industrial electricity consumers.
Clearer regulatory frameworks may ultimately enhance investor confidence in electricity infrastructure projects connected to the national grid.
RISK RADAR
Operational risk remains significant within Nigeria’s transmission network, where infrastructure constraints and coordination challenges frequently disrupt electricity supply.
Regulatory risk also exists as new permitting requirements introduce additional compliance obligations for private infrastructure operators.
Technology implementation risk may arise as system operators deploy digital monitoring tools across multiple substation interconnection points within a short timeline.
