Solutions to Clean Power to Remote Off-grid Mining Operations in Nigeria
By Tarik Sfendla
The energy markets are undergoing a massive transformation as governments around the world transition away from fossil fuels towards the integration of renewable energy. This trend is clearly visible in the mining industry as demonstrated by recent power projects in South America and in Australia.
According to Bloomberg New Energy Finance, in 2018, mines purchased 1 GW of renewable energy generation assets; this amount tripled to reach approximately 3.5 GW in 2019, 90% of which consists of hybrid solutions.
Electricity demand for the mining industry is expected to increase significantly in the coming years as increased mine depth, harder rock and greater water desalination needs lead to higher energy intensity for the industry.
Whilst electrification of operations and vehicles is reducing certain emissions and generating cost savings, stakeholder targets to reduce emissions as part of the EESG (Environmental, Economic, Social & Governance) plans, is increasing the renewable share of the energy mix, which of course requires high flexibility in the generation to balance intermittent renewables.
In Africa, the mining sector faces inherent challenges, access to the power grid and grid reliability being the most significant. With most electricity supply coming from conventional power plants (coal, oil or gas), operators are challenged on the one hand with highly volatile operating expenses due to rising fuel costs, and by inefficient, unreliable power supply leading to costly production disruption and revenue losses on the other. Weak infrastructure and water availability compound the challenges for mines, particularly in remote, off-grid locations.
The combination of these trends and particularities of the African markets are setting the scene for the integration of renewables for the mining sector. A recent study by McKinsey showed that moving to renewable electricity sources is becoming increasingly feasible, even in off-grid environments, as the cost of electricity storage is set to decline by 50% from 2017 to 2030. This is especially good news for Africa where the cost of solar energy generation could be among the lowest in the world.
It also represents a huge opportunity for operators in Africa, where Wärtsilä has developed a range of competitive strategies to deliver efficient and reliable power supply solutions to support the mining sector on its path towards a renewable energy future.
In Tanzania, the Geita gold mine was experiencing reliability issues and power shortages as its ageing power plant was reaching the end of its useful life. It needed a reliable power generation solution to support its growing operations.
Wärtsilä delivered a 40 MW flexible power plant and agreed to a 10-year operation and maintenance (O&M) package, integrating technology with lifecycle services to provide “always-on” power. The plant secures uninterrupted off-grid power supply, eliminating revenue losses from power shortages, while the O&M agreement is tailored to the mine’s day-to-day performance requirements.
Maintenance schedules are optimised to minimize costs and production downtime and enhance fuel efficiency. As a result, fuel savings of around 4%, representing $2 million USD, were achieved in the first year of operation. The flexibility of the installation will also facilitate the transition to renewables over the project lifetime.
In Burkina Faso, Wärtsilä has delivered a 15 MWp solar photovoltaic (PV) power plant to the independent power producer (IPP) Essakane Solar SAS, which supplies the Ekkasine gold mine. The solar PV plant was constructed next to a 55 MW power plant running on heavy fuel oil. The engine power plant provides backup, while the solar farm produces energy during the day. The capability to control and optimise the usage of the solar PV power and engines enables the gold mine to reduce its fuel consumption by an estimated 6 million litres per year and its annual CO2 emissions by 18,500 tons.
Energy Storage technologies are the true game-changer
The integration of energy storage technologies will be the real game-changer, enabling the industry to take full advantage of cheap and plentiful solar power. They have the unique ability to provide a buffer between supply and demand by delivering or storing energy whenever it is most needed. They will become the key building block of the stable infrastructure needed to improve grid reliability and security.
Hybrid solutions, combining flexible thermal generation with storage and solar power operations are now a realistic and cost-effective solution, as the levelled cost of electricity (LCOE) is lower than ever, and costs of storage are set to decline.
In Mali, at the Fekola mine, located in a remote area with no connection to any larger grid, Wärtsilä is providing an off-grid hybrid solution to provide and maintain microgrid stability. The project combines a 30 MW solar PV plant, a 17.3 MW / 15.4 MW energy storage facility and GEMS, Wärtsilä’s advanced energy management system, with the mine’s existing 64 MW power generator to improve power reliability, reduce heavy fuel consumption, save costs and reduce CO2 emissions.
GEMS is a ground-breaking tool, using smart algorithms to dispatch energy storage and multiple generation assets (thermal and renewable) with the right reserve level to maintain high grid reliability for the mine. Gensets are switched off as solar output increases and are restarted based on forecasted data including load demand and weather. The sophistication of GEMS enables energy production optimization to ensure the lowest LCOE.
In addition to ensuring microgrid stability, the project is expected to generate long-term annual savings of 13.1 million litres of heavy fuel oil and reduce the mine’s carbon footprint by approximately 39,000 tons per year. This hybrid storage project is the first of its kind in Mali and in the mining sector, demonstrating the growing case for clean energy and its sustainable and economic potential for mines in Africa and elsewhere.
Increasing energy reliability and lowering operating costs are essential for the mining sector. The optimal solution to solve the power challenges must allow for fast starting with high off-grid availability, high fuel efficiency, fast load following and part-load efficiency to allow high penetration of renewables. The answer lies in a combination of advanced flexible energy generation strategies and the smart use of renewables to guarantee the delivery of efficient and reliable power in remote off-grid locations. Advanced energy management systems are the key technological element required to support the huge inflows of power from intermittent sources.
With an extensive portfolio of energy storage and flexible solutions for energy-intensive operations, in Africa and the rest of the world, Wärtsilä is the partner of choice to support the mining sector achieve its sustainability and cost-saving goals.

Three Interdependent Pillars Reshaping African Financial Infrastructure
By Winston Osuchukwu
Africa’s financial infrastructure is entering a defining phase. Digital adoption continues to accelerate, financial inclusion is deepening, and institutions across the ecosystem are investing in connected, data-driven services. According to the World Bank’s Global Findex Database, account ownership across Sub-Saharan Africa has expanded significantly over the past decade, while mobile money continues to process hundreds of billions of dollars annually. Sustained investment in Africa’s fintech ecosystem reflects the same growing confidence in the continent’s financial future.
As the ecosystem matures, success will depend less on isolated innovation and more on how institutions connect their capabilities. The next phase of financial infrastructure is being shaped by three interdependent pillars: connected ecosystems that widen the data available on each customer, data intelligence that turns that scattered data into a single coherent picture, and intelligent decision-making that turns insight into measurable outcomes.
Connected Ecosystems Create the Foundation for Intelligence
No single institution has a complete view of the financial ecosystem. Banks, fintechs, payment providers, telecommunications companies, regulators, and other participants each contribute different pieces of the picture. As these organisations become more connected through interoperable payment systems, shared infrastructure, and collaborative partnerships, financial services become more accessible and seamless for individuals and businesses alike.
Connectivity alone, however, is not enough. A more connected ecosystem also creates exponentially more data, and unless that information can be integrated and interpreted consistently, greater connectivity simply produces greater complexity. The value of collaboration therefore depends on the ability to transform fragmented information into a coherent picture.
Data Intelligence Creates Shared Understanding
Once data flows across connected ecosystems, the next challenge is making sense of it. Financial institutions need more than access to information; they need the ability to unify diverse data sources, identify meaningful patterns, and generate insights that accurately reflect customer behaviour, operational performance, and emerging risks.
Data intelligence provides this common understanding. It enables institutions to move beyond isolated datasets and develop a trusted, enterprise-wide view that supports regulatory compliance, operational efficiency, and customer-centric innovation. Yet even the clearest insight has limited value if it remains descriptive. Understanding what is happening is only useful when institutions can confidently decide what to do next.
Intelligent Decisions Drive Real Outcomes
This is where artificial intelligence, predictive analytics, and machine learning become transformative. Built on a foundation of connected ecosystems and high-quality data intelligence, these technologies enable organisations to make faster, more consistent decisions across lending, fraud detection, compliance, customer engagement, and strategic planning.
Rather than replacing human expertise, intelligent decision-making augments it by helping institutions anticipate change, respond proactively, and allocate resources more effectively. When decisions are powered by reliable data and supported by a connected financial ecosystem, organisations become more resilient, customers enjoy better experiences, and the entire financial value chain operates more efficiently.
Africa’s financial future will not be shaped by technology or data in isolation. Progress requires that these capabilities work together. Connected ecosystems generate the information. Data intelligence transforms that information into “features” – the meaningful attributes of a customer’s behaviour that a model can learn from. Intelligent decision-making algorithms then convert those “features” into action. Together, they form the foundation of a financial infrastructure that is more inclusive, resilient, and capable of supporting sustainable economic growth.
At Mathesis Analytics, we turn information into action – helping financial institutions transform complex and frequently unstructured data into meaningful insights they can act on – helping financial institutions make sense of complex, fragmented data and lend confidently to the people and businesses driving Africa’s economy.

Heritage Bank and Dangerous Politics of Corporate Survival in Nigeria
By Blaise Udunze
The Heritage Bank’s banking license was revoked, and it was ordered into liquidation on June 3, 2024. This remains one of the most controversial and widely debated events in Nigeria’s financial sector.
The lingering concerns, even though official reasons have been given as regulatory breaches, inadequate capitalisation, and persistent financial distress, many people remain unconvinced or believe there are broader issues that deserve closer scrutiny. Surprisingly, to concerned Nigerians, this marks the first time a Nigerian bank has been allowed to fail in over a decade. Despite the passage of time, one question refuses to disappear. Mind you, this is not a rhetorical question: Does the failure of a bank in Nigeria reflect only the institution’s weaknesses or should it also raise questions about the effectiveness of regulatory oversight and the influence of broader systemic or political factors?
Again, the Central Bank of Nigeria (CBN) actually may have explained that its decision to revoke Heritage Bank’s licence was based on the institution’s persistent financial weakness, its inability to meet prudential requirements and the absence of a credible path to recovery. Yes, and undisputedly, those reasons fall squarely within the regulator’s statutory mandate to protect depositors and safeguard financial system stability.
Understandably, the legal basis for the action was clearly stated; even at that, the truth is that the decision has continued to provoke debate because of the broader question of regulatory consistency. If prudential weakness alone determines whether a bank survives, why have seemingly comparable institutions been treated differently?
This question deserves examination not through conspiracy theories or unsubstantiated allegations but through the lens of institutional accountability, governance and the relationship between politics and business in Nigeria.
The Heritage Bank story presents a contradiction. No doubt, one would not be wrong to say that the Nigerian banking industry is one of the most tightly regulated sectors of the economy. This is because the banks operated and still function under continuous supervision by the CBN. Also, the Nigeria Deposit Insurance Corporation (NDIC) is well known to exist primarily to protect depositors and ensure financial system stability. Routine examinations, prudential guidelines, capital adequacy monitoring, liquidity ratios, stress tests and early intervention mechanisms are designed precisely to prevent sudden institutional collapse.
One critical question that comes to mind is, if these safeguards function effectively, why should a licensed commercial bank deteriorate to the point of liquidation? That question extends beyond Heritage Bank. It touches the credibility of Nigeria’s financial architecture itself.
The truth be told, no regulator anywhere in the world can guarantee that every bank will survive. This is because over time, history has shown that banks can fail due to poor corporate governance, insider abuses, weak risk management, fraud, macroeconomic shocks or prolonged insolvency. Nigeria is no exception.
However, regulators are expected to detect distress early, enforce corrective actions and minimise losses to depositors and the economy. That is the essence of prudential regulation.
Consequently, whenever a licensed bank ultimately collapses, scrutiny naturally shifts beyond management failures to regulatory effectiveness. Did supervisors identify warning signs early enough? Were intervention tools deployed in time? Were recovery options exhausted before liquidation became inevitable? Could alternative resolutions have preserved confidence while protecting depositors?
The Heritage Bank case naturally fuels these questions because Nigeria’s regulatory history demonstrates that liquidation is not the only available resolution mechanism. Different institutions have, at different times, received different supervisory responses.
Throughout former CBN governor Godwin Emefiele’s leadership, several banks, including Skye Bank (later Polaris Bank), Keystone Bank, Union Bank, and Heritage Bank, faced severe financial challenges but were bailed out by the central bank instead of being allowed to fail. These banks continued operations until they were eventually sold off, with one currently distressed bank still operating despite negative shareholders’ funds.
For instance, Unity Bank was not widely regarded as financially stronger than Heritage Bank on several traditional indicators. Its 2023 audited financial statements reflected a negative capital adequacy ratio of -76.14 per cent, accumulated losses, and the external auditors drew attention to a material uncertainty regarding the bank’s ability to continue as a going concern. Despite these severe weaknesses, the regulatory response was not an immediate licence revocation. Instead, the CBN facilitated a merger with Providus Bank as a resolution strategy and approved a pivotal financial bailout package, reportedly worth N700 billion.
Likewise, First Bank of Nigeria is not left out of this trend; owing to its systemic importance and larger market presence, the institution later faced regulatory capital pressure following the withdrawal of regulatory forbearance in 2025. Another concern is that rather than withdrawing its licence, the regulator permitted the bank to remain operational under a recapitalisation programme supported through supervisory measures.
These examples do not necessarily suggest that the banks were identical in their financial positions, nor do they prove that Heritage Bank deserved the same outcome. Each institution presents unique circumstances, regulatory assessments and systemic implications. Nevertheless, on common ground, they raise a legitimate policy question. What specific factors determine when the regulator opts for recapitalisation, merger, restructuring or liquidation? One fact the regulators should know and take into cognisance is that greater transparency around these decisions would strengthen public confidence in the consistency and predictability of financial regulation, as this remains sacrosanct.
Of course, the case of Heritage Bank’s liquidation has generated a broader conversation because of Nigeria’s history, where business fortunes have sometimes intersected with political transitions, elite rivalries and shifting centres of influence, which is more troubling.
The common truth is that across decades of experience, Nigerian businesses have occasionally found themselves flourishing under one political environment only to struggle under another. Consistently, this has always been a trend that changes in government have often altered regulatory priorities, access to public sector business and investor confidence. While correlation does not establish causation, the perception that politics influences commercial outcomes remains deeply entrenched. This perception becomes even more significant when examining businesses that occupy strategic sectors.
Banks are strategic institutions. Telecommunications companies are strategic institutions. Energy companies are strategic institutions.
Government actions affecting such businesses inevitably attract public scrutiny because their operations extend far beyond shareholders to millions of citizens.
One may be moved to ask what the direct connection is. The controversy surrounding MultiChoice Nigeria offers another example of how commercial disputes can quickly assume political dimensions in public discourse. The direct connection may remain a puzzle to so many.
A thorough search revealed that over recent years, especially around the time the Heritage Bank licence was revoked, it was clear that MultiChoice faced regulatory sanctions, tax disputes, consumer protection battles, pricing controversies and legal confrontations with Nigerian authorities. Come to think of it, at different points, observers speculated that sustained pressure on the company reflected broader political or economic interests rather than purely regulatory concerns.
It is important to distinguish speculation from verified fact. Nigerian authorities consistently maintained that their actions against MultiChoice were based on compliance with tax, competition and consumer protection laws. MultiChoice similarly defended its commercial decisions through legal channels.
Well, at this point, Adewunmi Ogunsanya, a Senior Advocate of Nigeria (SAN), has direct ties to both organisations through his executive leadership and corporate board appointments. Is it a mere coincidence that his connection to both entities became a major financial focal point following the liquidation of Heritage Bank?
Let it be known that, despite all, the public conversation often framed the disputes as evidence of an underlying power struggle between government institutions and a dominant private enterprise, and this may remain undisputed.
Whether accurate or not, such perceptions matter because markets respond not only to facts but also to confidence. Confidence is the currency upon which banking survives.
Unlike manufacturing companies that own factories or oil firms with physical reserves, banks fundamentally operate on trust. Depositors leave their money because they believe regulators will ensure the institution remains safe.
One indisputable fact is that the moment confidence evaporates, even a fundamentally solvent bank can face severe liquidity pressure, which has occurred in the past.
This is why central banks across the world routinely rescue distressed institutions, not necessarily because every management deserves saving, but because preserving confidence is often more valuable than punishing failure.
Nigeria demonstrated this principle during the 2009 banking crisis through recapitalisation, management changes, the establishment of AMCON and structured resolution mechanisms rather than the outright closure of several distressed institutions. That experience confirmed that regulators possess a range of tools beyond licence revocation.
The Heritage Bank case therefore naturally invites debate over why liquidation emerged as the chosen option.
Could recapitalisation have remained feasible? Could acquisition have produced better outcomes? Could bridge-bank arrangements have preserved value? Could additional restructuring have protected jobs and investor confidence?
These are questions policymakers should openly address, not simply to revisit the past but to strengthen future crisis management. The implications extend beyond one institution.
Foreign investors closely observe how governments and regulators manage corporate distress. Let it be known that predictability is one of the strongest attractions for investment. When investors perceive that outcomes depend primarily on transparent rules, confidence grows.
When they perceive uncertainty, whether arising from inconsistent regulation, political transitions or muddy decision-making, they demand higher risk premiums or redirect capital elsewhere.
Nigeria cannot afford either perception. The country’s ambition to become Africa’s leading investment destination and to build a $1 trillion economy requires regulatory consistency that transcends political cycles.
Businesses must believe that success or failure depends principally on compliance, competitiveness and sound governance, not changing political winds.
This is equally important for regulators themselves. Institutions such as the CBN and NDIC derive legitimacy from public confidence. This is to say that absolute confidence increases when regulatory decisions are accompanied by clear, detailed and transparent explanations that address public concerns effectively, which would not give room for doubt.
Where communication gaps exist, the simple truth is that speculation inevitably fills the vacuum. And worse still, in today’s digital environment, silence often becomes fertile ground for misinformation. Transparency therefore serves not merely public relations purposes but financial stability itself.
The Heritage Bank episode also exposes another challenge confronting Nigeria’s economy, as this can be tied to the growing fusion of politics and perception.
Even where regulatory decisions are technically justified, public trust weakens if citizens increasingly interpret every major corporate action through political lenses. That should concern policymakers.
An economy where investors suspect political motivations behind regulatory outcomes ultimately discourages entrepreneurship, weakens market confidence and slows economic growth.
The solution is not to avoid difficult regulatory decisions. Poorly managed institutions should still face appropriate sanctions. More importantly, financial discipline remains indispensable.
It must be ensured that whilst this is done, enforcement consistently demonstrates fairness, proportionality and procedural transparency. Equally, corporate leaders must recognise that sustainable institutions cannot depend on political proximity.
History repeatedly shows that businesses built primarily on access rather than competitiveness become vulnerable whenever political landscapes change. Strong institutions survive governments because they are anchored in sound governance rather than political patronage.
Perhaps the greatest lesson from Heritage Bank is not merely whether politics influenced events, something that remains unproven in the public domain, but whether Nigeria’s institutional framework has become sufficiently trusted that such questions no longer dominate public discourse.
That is the real challenge. A mature regulatory environment should inspire confidence that decisions arise from objective evidence rather than perceived political calculations.
Until that confidence is universally shared, every major corporate failure will continue generating political interpretations regardless of the underlying facts.
Nigeria’s economic future depends not only on stronger banks but also on stronger institutions. The CBN, NDIC and every financial regulator carry responsibilities extending beyond enforcing compliance. They must also preserve public confidence through transparency, consistency and accountability.
Heritage Bank should therefore become more than another chapter in Nigeria’s banking history. It should become an opportunity for honest national reflection.
Not on how to rescue failing banks indefinitely, but on how to build regulatory systems so credible, so predictable, and so independent that no bank failure, however justified, will immediately trigger suspicions of hidden political battles.
For investors, depositors and ordinary Nigerians alike, that confidence may ultimately prove more valuable than any financial bailout.

Reimagining Kaduna Through the Promise of Education
By Sani Abdulrazak, PhD
The late Sir Ahmadu Bello, the Sardauna of Sokoto and Premier of Northern Nigeria, envisioned that the true measure of a society’s progress lay not just in the roads it built, the markets it opened or the wealth it accumulated, but in the education of its people.
A philosophy it was, born from the conviction that the most enduring obelisk any generation can leave behind is not one hewn in stones, but one etched into the minds of its children. Decades later, that timeless belief still resonates across Northern Nigeria, a reminder that every investment in education is, unquestionably, an investment in today and tomorrow.
Truth is, failure to educate a child is synonymous with condemning the next generation; it is amplifying an already debilitating multidimensional poverty, it is fuelling the flames of insecurity. Governor Uba Sani of Kaduna state shares this belief, and three years later under his watch, the state’s education sector tells a promising story that gives every resident of the state reason to hope…to believe.
A school is indeed more than bricks and mortar; it is a place where the future is quietly assembled. Sadly, countless classrooms across Kaduna reflected neglect rather than hope. Governor Uba Sani’s administration chose to change that narrative. Within three years, 736 new classrooms have been constructed and 2,326 renovated, while 30,742 pupils’ desks and 3,704 teachers’ tables and chairs have been supplied.
The government also completed 62 new secondary schools, with another 50 under construction. Through the School Access Project, between 102 and 104 additional schools are being established so that no child travels more than one kilometre to access education. Furthermore, six science secondary schools that had remained abandoned for over a decade have been completed and reopened by the present administration. Today, they provide quality science education to over 2,000 students.
Rising tuition fees by the previous administration had placed higher education beyond the reach of many families in Kaduna and beyond. The administration responded with a 50 per cent reduction in tuition fees across Kaduna State-owned tertiary institutions, including Kaduna State University and Nuhu Bamalli Polytechnic, reportedly increasing enrolment by over 200%. Kaduna State Government also paid approximately ₦407.94 million, equivalent to 247,235.84 United States dollars, to settle outstanding tuition for Kaduna-sponsored students studying abroad, while investing over ₦1 billion in scholarships, student loans and educational support programmes.
It is indeed true that education is only as strong as its custodians, the teachers. Recognising this, the administration recruited 10,000 teachers and trained more than 33,000 education personnel in modern teaching methods and digital learning. These investments are already yielding results, with students obtaining five credits and above in WAEC, NECO and NABTEB examinations increasing from 54 per cent to 67 per cent.
Nothing illustrates the measure of progress of this administration’s investment in education better than the decline in out-of-school children. Through expanded school access, improved infrastructure, tuition support and enhanced security, the number reportedly fell from about 580,000 to approximately 182,000, giving hundreds of thousands of children another chance at education.
Believing that education must ready young people for employment and enterprise, Kaduna State Government established three Institutes of Vocational Training and Skills Development in Soba, Rigachikun and Samaru Kataf, offering practical skills in ICT, renewable energy, mechatronics, welding, plumbing, fashion design, carpentry and automotive technology. The administration has also advanced inclusion through the nearly completed Special School for Gifted Children and the expansion of the Tsangaya Bilingual Schools Project with specialised teacher training.
Binding these educational reforms together is sustained investment. Between 2024 and 2026, Kaduna consistently allocated between 25 and 26.14 per cent of its annual budget to education, making it the state’s highest-funded sector. More than a budgetary decision, it is a declaration that Kaduna’s future will be built not only with roads and buildings, but with educated minds.
There is an African proverb that says, “The child who is carried on the back today may carry the nation on his shoulders tomorrow.” Make of that what you will, but only education will give the child the shoulders to do so. Generational chapters and eras are defined by battles won or lost, sometimes by monuments raised or conceived.
However, the most discerning write their legacy upon the minds via education, for no monument endures longer than an educated generation. Who’d better write us this chapter than the proverbial Lannister of our time, Governor Uba Sani? A leader elected because the people of Kaduna State knew he would be a reformist, and now he is shifting the tectonic plates of education…of governance in the state.
Even though a lot of work remains unfinished, the road ahead is anything but smooth. What is beyond doubt is the direction the state is heading towards. Should these reforms endure under the SUSTAIN Agenda, Kaduna may one day look back on Uba Sani’s first three years not merely as an era of educational reforms, but as the moment when the state chose to invest in the one sphere that time cannot diminish: the education of its people.
