The Nigerian Electricity Regulatory Commission (NERC) has ordered the System Operator (SO), a department in the Transmission Company of Nigeria (TCN) to commence the capping of power supply to cross-border customers in Benin Republic, Niger and Togo.
This is in a bid to increase power availability to Nigerians,a document tagged: ‘Interim Order on Transmission System Dispatch Operations, Cross-border Supply and Related Matters’,said.
The power sector regulator stated that the directive will last for six months in the first instance before review.
NERC’s order, dated April 29, 2024, and which became effective from May 1, 2024, was signed by the commission’s Chairman, Sanusi Garba, and Vice Chairman, Musiliu Oseni andIn the order, the regulatory agency directed that power delivery to Nigeria’s neighbours must not exceed six per cent of total grid electricity at any point in time.
It emphasized that following the implementation of the April 2024 supplementary order, the commission had observed sub-optimal grid dispatch operation practices.
It said that this has compromised the Distribution Companies’ (Discos) ability to deliver on its Service Based Tariff (SBT) committed service levels to end-use customers with a significant impact on market revenues.
NERC said the system operator’s sole reliance on limiting Discos’ load off-take/allocation in managing recurring grid imbalances while prioritising international off-takers and Eligible Customers (ECs) is neither efficient nor equitable.
The practice so far adopted by the operator in managing generation availability, it said, has caused significant hardship to Discos’ customers, comprising industrial, commercial, and residential, especially during peak demands while prioritising delivery to other bilateral contracts, including export to international customers.
It noted that the current international and bilateral contracts with Generation Companies (Gencos) were based on best-endeavour and with loose terms that are often below the minimum contract standards currently operated in the industry.
It said many of the off-takers contracted bilaterally by Gencos often abuse this prioritisation and raise their off-takers during peak operations beyond their contracted levels at the expense of other grid users without attendant penalties for violation of grid instructions.
According to NERC, the order serves as an interim measure to guide the operations of the system operator and the TCN to implement Standard Operating Procedures (SOPs) to improve transparency and fairness of grid operations in delivering better services to all customers.It urged the system operator to place interim caps on capacities supplied to international customers for six months from the effective date of the order, thus minimising the displacement and impact on domestic supply obligations by Gencos.
“The commission hereby orders as follows: The system operator shall develop and present to the commission for approval within seven days from the issuance of this order a pro-rata load-shedding scheme that ensures equitable adjustment to load allocation to all off-takers — Discos, international customers, and eligible customers — in the event of a drop in generation and other under-frequency related grid imbalances necessitating critical grid management.
“The system operator shall implement a framework to log and publish hourly readings and enforce necessary sanctions for violation of grid instructions and contracted nominations by off-takers in line with the grid code and market,” it stated.
It further directed that the system operator shall publish and notify all market participants and the commission of the previous day’s hourly log readings of off-take by market participants and the market settlements report by 12:00 noon of the next day.
“The system operator shall ensure that the maximum load allocation to international off-takers in each trading hour shall not be more than six per cent of the total available grid generation.
“The aggregate capacity that can be nominated by a generating plant to service international off-takers shall not be more than 10 per cent of its available generation capacity unless in exceptional circumstances a derogation is granted by the commission.“The system operator shall henceforth cease to recognise any capacity addition in bilateral transactions between a generator and an off-taker without the express approval of the commission,” it added.
It urged the system operator and TCN to immediately initiate and install integrated Internet of Things (IoT) meters at all off-take and delivery points of eligible customers, bilateral supplies, cross-border trades, and outgoing 33kV feeders of the Discos to provide real-time visibility of aggregate offtake by grid customers.“The installation of and streaming of data from the IOT meters should be completed within three months from the date of this order,” it added.
