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.

In Praise of Nigeria’s Elite Memory Loss Clinic
By Busayo Cole
There’s an unacknowledged marvel in Nigeria, a national institution so revered and influential that its very mention invokes awe; and not a small dose of amnesia. I’m speaking, of course, about the glorious Memory Loss Clinic for the Elite, a facility where unsolved corruption cases go to receive a lifetime membership in our collective oblivion.
Take a walk down the memory lane of scandals past, and you’ll encounter a magical fog. Who remembers the details of the N2.5 billion pension fund scam? Anyone? No? Good. That’s exactly how the clinic works. Through a combination of political gymnastics, endless court adjournments, and public desensitisation, these cases are carefully wrapped in a blanket of vagueness. Brilliant, isn’t it?
The beauty of this clinic lies in its inclusivity. From the infamous Dasukigate, which popularised the phrase “arms deal” in Nigeria without actually arming anything, to the less publicised but equally mystifying NDDC palliative fund saga, the clinic accepts all cases with the same efficiency. Once enrolled, each scandal receives a standard treatment: strategic denial, temporary outrage, and finally, oblivion.
Not to be overlooked are the esteemed practitioners at this clinic: our very own politicians and public officials. Their commitment to forgetting is nothing short of Nobel-worthy. Have you noticed how effortlessly some officials transition from answering allegations one week to delivering keynote speeches on accountability the next? It’s an art form.
Then there’s the media, always ready to lend a hand. Investigative journalists dig up cases, splash them across headlines for a week or two, and then move on to the next crisis, leaving the current scandal to the skilled hands of the clinic’s erasure team. No one does closure better than us. Or rather, the lack thereof.
And let’s not forget the loyal citizens, the true heroes of this operation. We rant on social media, organise a protest or two, and then poof! Our collective short attention span is the lifeblood of the Memory Loss Clinic. Why insist on justice when you can unlook?
Take, for example, the Halliburton Scandal. In 2009, a Board of Inquiry was established under the leadership of Inspector-General of Police, Mike Okiro, to investigate allegations of a $182 million bribery scheme involving the American company Halliburton and some former Nigerian Heads of State. Despite Halliburton admitting to paying the bribes to secure a $6 billion contract for a natural gas plant, the case remains unresolved. The United States fined the companies involved, but in Nigeria, the victims of the corruption: ordinary citizens, received no compensation, and no one was brought to justice. The investigation, it seems, was yet another patient admitted to the clinic.
Or consider the Petroleum Trust Fund Probe, which unraveled in the late 1990s. Established during General Sani Abacha’s regime and managed by Major-General Muhammadu Buhari, the PTF’s operations were scrutinised when Chief Olusegun Obasanjo assumed office in 1999. The winding-down process uncovered allegations of mismanagement, dubious dealings, and a sudden, dramatic death of a key figure, Salihijo Ahmad, the head of the PTF’s sole management consultant. Despite the drama and the revelations, the case quietly faded into obscurity, leaving Nigerians with more questions than answers.
Then there is the colossal case of under-remittance of oil and gas royalties and taxes. The Federal Government, through the Special Presidential Investigatory Panel (SPIP), accused oil giants like Shell, Agip, and the NNPC of diverting billions of dollars meant for public coffers. Allegations ranged from falsified production figures to outright embezzlement. Despite detailed accusations and court proceedings, the cases were abandoned after the SPIP’s disbandment in 2019. As usual, the trail of accountability disappeared into thin air, leaving the funds unaccounted for and the public betrayed yet again.
Of course, this institution isn’t without its critics. Some stubborn Nigerians still insist on remembering. Creating spreadsheets, tracking cases, and daring to demand accountability. To these radicals, I say: why fight the tide? Embrace the convenience of selective amnesia. Life is easier when you don’t worry about where billions disappeared to or why someone’s cousin’s uncle’s housemaid’s driver has an oil block.
As World Anti-Corruption Day comes and goes, let us celebrate the true innovation of our time. While other nations are busy prosecuting offenders and recovering stolen funds, we have mastered the fine art of forgetting. Who needs convictions when you have a clinic this efficient? Oh, I almost forgot the anti-corruption day as I sent my draft to a correspondent very late. Don’t blame me, I am just a regular at the clinic.
So, here’s to Nigeria’s Memory Loss Clinic, a shining beacon of how to “move on” without actually moving forward. May it continue to thrive, because let’s face it: without it, what would we do with all these unsolved corruption cases? Demand justice? That’s asking a lot. Better to forget and focus on the next election season. Who knows? We might even re-elect a client of the clinic. Wouldn’t that be poetic?
Now, if you’ll excuse me, I have a new scandal to ignore.

How Nigerian Companies are Leading More Responsible Digital Transformation
By Kehinde Ogundare
Artificial intelligence is everywhere–in polished social media posts, in the recommendations that guide our viewing habits, and in the bots that handle customer queries before a human agent steps in. On LinkedIn, AI-assisted writing has become standard practice.
A year ago, more than half of English long-form posts that went viral were estimated to have been written by or assisted by AI. If that’s the norm on the world’s biggest business network, it’s no surprise that AI is driving conversations in Nigerian boardrooms as companies move from experimentation to embedding AI into their daily operations.
Part of the package
The Nigeria Data Protection Act (NDPA), modelled on the European Union’s General Data Protection Regulation, together with the Nigeria Data Protection Commission, requires companies to build privacy into their systems from the outset rather than adding it later. This clear regulatory framework has evolved alongside a rapid rise in AI adoption.
New research from Zoho on responsible AI adoption highlights the impact of the regulations. As per the report, 93% of Nigerian companies have already started using AI in their daily operations; 84% have tightened their privacy controls after adoption, and 94% now have a dedicated privacy officer or team, which is well above global averages.
The survey, conducted by Arion Research LLC among 386 senior executives, shows just how deeply embedded AI has become in Nigeria. One in four companies already uses it across several departments, and nearly a third report advanced integration. Financial services firms are pioneers in this sector, using AI to automate client interactions, streamline operations and sharpen their marketing, while staying compliant with data protection rules.
The NDPA has helped make privacy part of business planning. Four in ten companies now spend more than 30% of their IT budgets on privacy. Regular audits, privacy impact assessments and explainability checks are becoming standard practice.
Skills, compliance and capacity
Rapid adoption brings challenges. More than a third of businesses say that their biggest obstacle is a lack of technical skills, and another 35% cite privacy and security risks. Instead of outsourcing, most are building capacity in-house: nearly 70% of companies are training staff in data analysis, more than half are improving general AI literacy, and 40% are investing in prompt engineering for generative tools.
The understanding of the NDPA regulation, which came into force in 2023, has also improved. 65% of organisations see compliance as essential. Many voluntarily apply data-minimisation and transparency standards even when not required to do so, aligning more closely with international norms and easing collaboration with global partners.
Privacy is increasingly influencing business decisions — from investment priorities to system design. Companies are asking tougher questions: is specific data essential? How can exposure be limited? How can fairness and transparency be proven?
Trusted systems
As privacy becomes part of how technology is built, companies are being more cautious about the tools they use because they now want systems that protect customer data, with clear boundaries between data and model training, straightforward controls, and reliable records for compliance teams.
Demand for business software that balances productivity with privacy is also growing. Zoho, among others, has seen strong customer growth as more organisations are looking for platforms that support responsible data handling.
The study identifies three main reasons behind AI adoption: to make work more efficient by automating routine tasks, to support better decision-making by identifying patterns sooner, and to improve customer engagement through faster, more relevant interactions. But none of this can succeed without trust. Nigeria’s experience shows that privacy and innovation can reinforce each other when they’re built together.
There’s still work to do because some industries are moving faster than others, and smaller businesses often face the biggest hurdles in time, cost and skills. Enforcement is also patchy; while the law is clear, application across sectors and geographies is a work in progress.
The next steps are more practical, requiring investment in skills – from data analysis and AI literacy to sector-specific training – and for governance to be put in place, with clear responsibilities, written policies, and a plan for managing errors or breaches. Privacy impact assessments should become part of every new system rollout, enabled by technology.
As AI becomes fundamental to doing business, Nigerian companies that build it carefully and responsibly will be better able to compete at home and abroad.

Nigeria’s Schools Closure and the Disease of Rhotacism
By Prince Charles Dickson, PhD
The inability to pronounce the letter r is called rhotacism—a quiet irony in speech pathology, where sufferers lack the tongue to name their condition. Nigeria today appears afflicted by a similar policy disorder: an incapacity to articulate the real threats to learning, safety, and development, while endlessly announcing their symptoms. The reflexive closure of schools across states, often with the Federal Government’s blessing, is not merely a security response; it is a linguistic failure of governance. We cannot pronounce the problem, so we silence the classroom.
At surface level, school closures masquerade as prudence. No leader wants abducted children, grieving parents, viral outrage. But development practice teaches us to distrust surface logic. If classrooms are unsafe, what calculus deems campuses secure? If primary schools are closed in the name of vulnerability, why do lecture halls hum, convocation grounds fill, churches and mosques swell, markets bustle, and political rallies roar? The policy geometry is incoherent. Risk does not dissolve with age brackets or academic levels; it migrates along opportunity lines. Violence, like water, flows where barriers are weakest—not where regulations are loudest.
The headline figures tell a damning story. Over 42,000 schools categorized as vulnerable. A $30 million Safe School Initiative announced, lauded, and then largely evaporated into PowerPoint memory. What exactly has closure achieved in this arithmetic? If risk prompted closure, closure must prompt mitigation. Yet what we witness is substitution, not solution. Strategy is replaced by symbolism. Doors are shut to demonstrate action while the engines of threat, the logistics, financing, intelligence gaps, and ungoverned spaces remain scandalously intact.
The first ethical question is not poetic distrust; it is arithmetic ethics. How many days of learning are lost per closure? How many children drift permanently out of school into child labor, early marriage, recruitment pipelines, or migration traps? Empirical evidence across fragile contexts, from the Sahel to Northeast Nigeria, shows that prolonged closures fracture educational trajectories irreversibly. A classroom shut today becomes a livelihood foreclosed tomorrow. When education systems stall, insecurity does not retreat; it recruits.
Development is not administered by press statements. It is built through boring, relentless infrastructure—data infrastructure, trust infrastructure, and response infrastructure. Consider Community Early Warning Systems (CEWS). Where they exist and function, attacks are anticipated, routes mapped, and escalation interrupted. Where they are absent, closure becomes the blunt instrument of last resort. Yet how many states have meaningfully integrated CEWS into school security architecture? How many have empowered bodies to convene multi-actor protection coalitions that include women, youth, traditional leaders, transport unions, and faith networks? The chalk does not hold risk; the cheque does. And the cheque has been shamefully mute.
Security is not the absence of pupils; it is the presence of intelligence. Closing schools without opening data is policy rhotacism. We cannot pronounce “threat mapping,” so we mouth “shutdown.” We cannot say “transport node vulnerability,” so we say “holiday.” We cannot articulate “perimeter hardening and community interception routes,” so we declare “postponement.” The oxygen of risk—enrolment points, travel corridors, marketplaces abutting school fences requires monitoring in real time. If threat mapping did not intensify the moment schools closed, then the threat merely changed address, not behavior.
The contradiction deepens when worship spaces remain open. Christian Association of Nigeria congregations gather. Nigeria Supreme Council for Islamic Affairs convenes faithful. If the doctrine is crowd risk, the exemptions are indefensible. If the doctrine is youth vulnerability, then universities must not be exempt. If the doctrine is intelligence deficit, then closure is an admission of systemic failure. You cannot claim safety by relocating learning into chaos. Faith spaces recognize a truth policy forgets: protection flows from relationship density. The congregation knows its strangers. Does the school gate?
Globally, contexts plagued by school-related violence have moved in the opposite direction—not toward retreat, but toward smart hardening. Drone reconnaissance over school corridors. AI-assisted risk scoring that fuses incident data, weather, market days, and movement patterns. Platforms to defuse land, grazing, and community disputes before they metastasize into school-adjacent violence. Psychosocial resilience units embedded in schools. Community rangers trained, insured, and supervised, not as vigilantes but as guardians accountable to law. Transparent pilots with public dashboards. Sanctions for local leaders who ignore warning signals. None of this is theoretical.
Because closure is administratively convenient. It transfers responsibility from execution to explanation. Once schools are shut, failure becomes abstract. Metrics blur. When exactly did the risk reduce? Who measures it? At what threshold does reopening occur? Without benchmarks, closure becomes the chief KPI of insecurity governance. That is not security architecture; it is security bureaucracy—forms without force, memos without muscle.
Local Government Areas on volatile frontiers—whether in Niger State or Kogi are living laboratories of conciliation culture. Traditional dispute resolution, faith mediation, women-led early warning, youth intelligence networks; these are not weaknesses to be ignored until Abuja’s biro approves boots on the ground. They are strengths to be funded, trained, and supervised. Development practice demands co-design. Are LGA leaders co-authoring protection protocols, or passively awaiting circulars? Centralization kills time; time kills children’s futures.
The opportunity costs of closure are staggering and gendered. Girls pay first and longest. Distance learning fantasies collapse where electricity, devices, and safety at home are uneven. Boys drift into non-state labor or armed networks promising income and belonging. Teachers disengage. Trust between communities and state frays further. When schools finally reopen—if they do—the damage is cumulative. Closure does not pause risk; it compounds it.
There is also a moral hazard. Normalizing closure teaches adversaries what works. Disrupt learning to extract concessions. Threaten the symbol to paralyze the system. Deterrence requires resilience. A state that keeps schools open while hardening them sends a different signal: intimidation will not erase futures.
To be clear, this is not romantic defiance. There are moments when temporary closure is warranted. But temporary requires temporality: timelines, triggers, alternatives. Closure without an accompanying surge in intelligence, infrastructure, and accountability is futility dressed as care. It is rhotacism—the inability to name and thus cure the disease.
So, the unperfumed questions must persist. What exactly is being done differently today that was not urgent yesterday? Where are the transparent pilots funded by the Safe School Initiative? Who owns the dashboards? Which perimeters were hardened, which routes monitored, which sanctions enforced? Who measures risk reduction, and when is bureaucracy upgraded into architecture?
Shutting schools may shelter minds briefly. But without strategy that attacks the root—financing of violence, data blindness, local exclusion, and accountability gaps—it only shelters the conscience of policy. Until answers arrive with evidence of execution, Nigeria’s schools are not closed for safety. They are closed for convenience. And convenience, like rhotacism, leaves us unable to pronounce the truth. May Nigeria win.
