Electricity distribution companies in Nigeria could face fresh sanctions over approximately N1.5 trillion in outstanding obligations after the Nigeria Independent System Operator, NISO, rejected repayment proposals submitted by some of the firms.
NISO said the decision followed a four-day public hearing held between September 1 and September 4, 2026, to examine outstanding obligations owed by the DisCos to the Nigerian Electricity Market and other service providers.
The hearing provided an opportunity to review the debts and consider payment arrangements proposed by the distribution companies.
However, NISO said some of the proposals were unacceptable, particularly considering the amount owed and how long some of the obligations had remained outstanding.
“Following extensive deliberations, the payment proposals presented by some of the DisCos were considered unacceptable to NISO at the hearing, particularly in view of the magnitude and age of the outstanding obligations,” the system operator said.
Debt Crisis Deepens Pressure on Power Sector
The latest development adds another layer to the longstanding financial problems confronting Nigeria’s electricity supply industry.
According to the report, the combined indebtedness of the 11 electricity distribution companies had already risen to about N1.3 trillion as of September 25, 2025, from approximately N1 trillion at the end of December 2024.
The latest figure of about N1.5 trillion indicates that substantial obligations remain unresolved despite previous attempts to address legacy debts within the electricity market.
The financial health of the distribution segment is particularly important because DisCos sit at the retail end of the electricity value chain, collecting payments from consumers and remitting funds through the market for electricity supplied and services provided by other participants.
Persistent shortfalls can therefore have consequences beyond the distribution companies themselves.
NISO Signals Tougher Position
NISO’s rejection of some repayment proposals indicates that the system operator is demanding more credible arrangements for settling outstanding obligations.
The hearing also gave the affected companies an opportunity to explain their financial positions and propose repayment structures before further enforcement measures are considered.
While the supplied report does not specify what sanctions will ultimately be imposed or which individual DisCos had their proposals rejected, NISO’s position increases pressure on operators to return with payment plans considered proportionate to their outstanding liabilities.
The development follows recent efforts to address other historical obligations in the electricity market, underscoring the scale and complexity of the sector’s liquidity challenges.
Resolving the debts will be important to improving confidence across the electricity value chain, where adequate cash flow is required for generation, transmission, system operations, infrastructure investment and reliable electricity supply.
For consumers, the bigger issue is whether ongoing financial reforms can ultimately translate into a more sustainable electricity market without further weakening service delivery.
