What Geregu’s return means for Nigeria’s power supply

Geregu Power Plc’s return to the national grid after more than six months offline comes at a critical juncture for Nigeria’s electricity sector, as the country continues to grapple with inadequate power generation and the financial pressures confronting sector operators.

The company reconnected its GT13 generating unit to the national grid on August 18 after completing the rehabilitation of a failed generator transformer.

Its second thermal power transformer is expected to be synchronized in September, with the third unit targeted for October.

The return of these units could gradually restore a significant generation asset to the national electricity system.

However, this development comes against the backdrop of a ₦40.09 billion bond crisis that has raised questions about Geregu’s financial stability, debt management, and investor confidence.

Geregu operates a 435-megawatt gas-fired power plant comprising three generating units, each with a capacity of about 145MW. The prolonged shutdown removed a sizable generation asset from a power system already struggling to translate installed capacity into a reliable electricity supply.

The company attributed the shutdown to operational challenges, including system turbulence, grid collapses, and the failure of a generator transformer, which required extensive repairs before the affected unit could return to service.

With GT13 back on the grid, attention shifts to the restoration of the remaining units. If the company meets its September and October targets, this phased restart could restore much of Geregu’s capacity and supply additional electricity to the national grid without the long lead time required to construct new plants.

This turnaround is critical because Nigeria’s electricity crisis is not merely a question of installed generation capacity. Gas availability, plant maintenance, transmission bottlenecks, grid instability, and the financial health of market participants all dictate how much power ultimately reaches consumers.

The Geregu outage starkly illustrates the recurring gap between installed capacity and actual available generation.

While Nigeria boasts several power plants with high nameplate capacities, equipment failures and operational constraints regularly wipe out hundreds of megawatts for extended periods. Geregu’s return offers an immediate opportunity to recover lost generation from an existing asset as the country works to support households, businesses, and industrial growth.

The restart also coincides with Geregu’s long-term expansion ambitions. The company has previously partnered with Siemens Energy on initiatives that could eventually scale its total capacity to roughly 1,200MW.

Yet, this operational recovery unfolds alongside severe financial headwinds.

Geregu recently defaulted on a scheduled payment for its ₦40.09 billion Series 1 Senior Unsecured Bond. The missed payment pertained to scheduled principal and coupon repayments rather than the entire bond principal. Issued in 2022 at a fixed coupon rate of 14.5 percent under Geregu’s ₦100 billion multi-instrument issuance program, the bond is due to mature in 2029.

The default sparked immediate investor alarm and prompted credit rating agency Agusto & Co. to withdraw Geregu’s “A-” rating. Agusto noted that it could no longer rely on the company’s existing audited financial statements while an independent verification remained underway, adding that it would reassess the firm’s creditworthiness only after receiving reliable financial statements for the year ended December 31, 2025.

This development placed Geregu’s balance sheet under intense scrutiny, particularly amid a steep decline in recent operational earnings.

First-half results revealed that revenue plunged by about 78.7 percent year-on-year to approximately ₦18.65 billion, down from ₦87.63 billion recorded in the corresponding period of 2025. Profit after tax also tumbled roughly 88 percent to ₦2.54 billion from ₦20.27 billion.

The protracted generation shutdown explains much of this decline, as a thermal power producer relies entirely on plant availability to generate electricity and bill for revenue.

Although the company has since settled the outstanding bond obligations relieving immediate default pressures, the resolution has not fully dispelled broader concerns regarding financial disclosure standards, debt management capabilities, and the structural causes of the missed payment.

The crisis has also accelerated executive turnover. Mohammed Sani Jaoji was appointed Acting Chief Executive Officer effective August 17, following the conclusion of Sean Manley’s tenure.

The appointment remains subject to approval by the Nigerian Electricity Regulatory Commission. This leadership change comes at a delicate moment, as the executive team must simultaneously restore generation capacity and rebuild capital market trust.

For Nigeria’s electricity market, the immediate value of Geregu’s restart lies in restored megawatts. However, the broader lesson extends far beyond output metrics. A viable generating company requires functional equipment, steady gas feedstocks, an evacuation grid capable of wheeling its power, and a financially solvent market structure that supports plant maintenance, debt service, and capital expansion.

The Geregu experience reflects these interconnected pressures. The six-month shutdown crippled the company’s cash flows while its fixed debt commitments remained due.

For the broader power sector, this episode underscores the absolute necessity of maintaining cash liquidity to support equipment reliability.

While Nigeria needs new power projects, preserving and running existing assets remains the most urgent short-term priority.
If Geregu successfully restores all three units on schedule, it will once again serve as a cornerstone of national supply.

However, realizing its 1,200MW expansion plan will depend heavily on the company’s ability to attract and deploy capital sustainably.

For investors, the narrative around Geregu is no longer solely about plant capacity, but whether that capacity can run reliably, generate predictable cash flow, and rest on a viable balance sheet.

For the power sector at large, it serves as a reminder that added capacity only delivers value when plants stay online and their operators remain financially sound. Geregu’s grid reconnection delivers a vital operational boost, but cementing its financial recovery will ultimately decide whether those megawatts can be sustained.
