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.

Sunusi Bature: Time to Take the Podium

By Ahmad Dambazau
The National Assembly is a constitutional locomotive for any purposeful democratic government, it provides checks to the government of the day and a legal basis for the system in general .This basically accounts for the high respect usually accorded and, of course, the attendant high expectation placed on it. The legislative arm of government like any other is saddled with the responsibility enshrined in the constitution and among such major functions includes representation, oversight and law making in addition to many other numerous functions.
Be that as it may, it has been a genuine cause for worry for Nigerians that, despite our series of experimentation with democracy, our legislators have performed below expectation. Their handling of national issues has especially remained without constitutional decorum and political experience required of people of their exalted status. Part 2, Section 4 of the 1999 Constitution, as amended, vests the legislative powers of the federation on the National Assembly which comprises the Senate and House of Representatives.
Dawakin Tofa ,Tofa and Rimin Gado Federal constituency is one of the few constituencies in Nigeria represented by the same legislator for 18 years(2007-2005) despite poor representation .
As the federal constituency searches for the best man to represent them for this serious legislative task. One name keeping ringing bell is Hon Sunusi Bature Dawakin Tofa ,Media and Communication Expert and Director General of Media and Publicity to Kano State Governor.Sunusi has earlier served as the Chief Press Seceretary to the Governor in the early days of the administration .

Nigeria’s Mining Reforms: Unlocking Investment and Growth

Over the past two years, Nigeria has implemented key policies and reforms to revitalize its mining industry, attract investment and strengthen the sector’s contribution to GDP.
Recent government-led initiatives have streamlined licensing processes, removed bottlenecks and simplified market entry for international investors, enhancing production across the country’s 44 solid mineral types.
As Africa’s premier mining investment event, African Mining Week (AMW) 2025 will convene Nigerian and African stakeholders with global investors and industry leaders to drive deal-making and accelerate sector growth.
Launch of Mineral Resources Decision Support System
In May 2024, the Nigerian Geological Survey Agency unveiled the Mineral Resources Decision Support System to provide global investors with easy access to geological and policy data.
The platform markets Nigeria’s vast mineral resources and critical infrastructure, assisting investors in making informed decisions about the country’s mining sector. By enhancing data transparency and accessibility, the system aims to streamline investment processes and boost investor confidence in Nigeria’s mining industry.
Restructuring of Ministry
To improve efficiency, Nigeria restructured the Ministry of Mines and Steel Development in August 2023, creating two separate entities. The Ministry of Solid Minerals Development focuses on upstream activities and investment facilitation, while the Ministry of Steel Development oversees the development of steel and metallic resources to drive industrial growth. This restructuring aims to enhance sector-specific governance, attract targeted investments and accelerate the country’s mineral and steel value chain development.
Approval of Nigerian Minerals & Mining Bill
Approved in April 2023 and currently under public review, the Nigerian Minerals & Mining Bill aims to introduce incentives for foreign investors while strengthening local content requirements. Once enacted, it will become the sector’s primary legal framework, enhancing transparency and investor confidence.
The bill is also expected to modernize regulatory oversight, ensuring sustainable resource management and aligning Nigeria’s mining sector with global best practices.
Implementation of Nigeria Mineral Value Chain Regulations
Implemented in July 2021, the Nigeria Mineral Value Chain Regulations mandates local processing of raw minerals such as gold and lithium, encouraging downstream investment.
Following this policy, China’s Avatar Energy Materials Company launched a 4,000-ton-per-annum lithium processing facility in Nasarawa State in May 2024, while Ming Xin Mineral Separation Nig Ltd. is developing a lithium processing plant in Kaduna State to support EV e battery production.
These investments mark a significant step toward positioning Nigeria as a key player in the global critical minerals supply chain. Against this backdrop, AMW 2025 will provide a platform for industry leaders to explore Nigeria’s evolving mining landscape and engage with global investors.

Natashagate: Suspension in the Eyes of Court Ruling

Abba Dukawa
Despite the position of the Court of Appeal in the case of the Speaker of Bauchi State House of Assembly Vs Hon Rifkatu Samson Danna (2017) 49 W.R.N that a lawmaker is a representative of his people whose membership of the House is guaranteed by the Constitution and not by any other person or persons, the Senate and its leadership have continued to use suspension as an instrument to oppress, intimidate and whip lawmakers into line.
Sadly, the National Assembly has continued to ignore the position of the courts on suspension of lawmakers as the Senate Committee on Ethics, Privileges and Public Petitions recommended a six-month suspension for the lawmaker representing Kogi Central Senatorial District, Senator Natasha Akpoti-Uduaghan, over her dispute with the Senate President, Senator Godswill Akpabio, following her alleged violation of the Senate’s rules.
A few hours after the committee submitted its report, the Senate quickly adopted the recommendations and slammed a six-month suspension on the lawmaker, depriving her senatorial zone representation in the Red Chamber, in violation of the Constitution, which guarantees that each of the 109 senatorial districts in the country shall be represented in the upper legislative chamber.
Her suspension for six months has raised legal issues as it is also in breach of various court judgments in the previous cases involving Senators Ali Ndume and Ovie Omo-Agege, as well as Dino Melaye and 10 other members of the House of Representatives, as well as Bauchi and Ondo states’ lawmakers.
When the Senate on March 30, 2017, suspended Senator Ndume for 90 legislative days for not “conducting due diligence” before filing a petition against the then Senate President, Dr Bukola Saraki, Justice Babatunde Quadri of the Federal High Court in Abuja nullified his suspension, declaring the action illegal, unlawful and unconstitutional. Delivering judgment in the suit marked FHC/ABJ/CS/551/2017, which Ndume filed, the judge said the suspension was in violation of Sections 68 and 69 of the Constitution of the Federal Republic of Nigeria, 1999 (as amended) and Article 13(1) of the African Charter on Human and Peoples’ Rights (Ratification and Enforcement) Act CAP A9 Laws of the Federation of Nigeria, 2004.
The judge consequently ordered the Senate to pay the plaintiff his outstanding salaries and allowances. Again, Justice Nnamdi Dimgba of the Federal High Court in Abuja nullified the suspension, saying that while the National Assembly has the power to discipline its erring members, a legislator could not be suspended for more than 14 days.
A recent scandal involving Senator Natasha Akpoti-Uduaghan and Senate President Godswill Akpabio has raised questions about the integrity of Nigeria’s National Assembly. The controversy began when Akpoti-Uduaghan accused Akpabio of sexual harassment during an interview with Arise Television, alleging that he made inappropriate advances towards her at his residence in Uyo, Akwa Ibom State, in December.
Between February 28 and March 5, several senators publicly defended Senate President Godswill Akpabio, dismissing Senator Natasha Akpoti-Uduaghan’s allegations of sexual harassment. Senator Neda Imasuen, Chairman of the Senate Committee on Ethics, Privileges, and Public Petitions, was among those who defended Akpabio.
Undeterred, Akpoti-Uduaghan formalized her accusations by submitting a petition to the Senate on March 5, urging her colleagues to investigate her claims. However, the Senate swiftly dismissed the petition, citing a rule that prohibits senators from submitting petitions signed by them. Chairman Imasuen declared the petition “dead on arrival,” referencing Order 40, Subsection 4 of the Senate Standing Orders. The next day, the Senate voted to suspend Akpoti-Uduaghan for six months, citing misconduct and actions that allegedly brought the institution into disrepute. Akpoti-Uduaghan has rejected the Senate’s decision, vowing to continue representing her constituents.
In a statement, she condemned the move, saying: “Against the culture of silence, intimidation, and victim-shaming, my unjust suspension invalidates the principles of natural justice, fairness, and equity.” Akpoti-Uduaghan emphasized that her suspension does not withdraw her legitimacy as a senator and that she will continue to serve her constituents and the country until 2027 and beyond.
Former Senate President Bukola Saraki has called for a transparent investigation into the matter, emphasizing the need to safeguard the Senate’s integrity. However, the Senate’s decision to suspend Akpoti-Uduaghan for six months without investigating her allegations has sparked widespread criticism.
The Nigerian Bar Association Women Forum (NBAWF) Chairperson, Barrister Huwaila Ibrahim, has urged Senate President Godswill Akpabio and Senator Natasha Akpoti-Uduaghan, Chairman of the Senate Committee on Diaspora, to undergo a transparent and open investigation into allegations of misconduct involving both parties.
According to Ibrahim, an investigation would allow Senator Akpabio to clear his name and Senator Akpoti-Uduaghan to substantiate her claims.
Additionally, Ambassador Zainab Mohammed, spokesperson for the Coalition of Women in Governance (CWIG), has called for Senator Akpoti-Uduaghan’s recall following her six-month suspension, citing concerns that the suspension constitutes an assault on democracy and a betrayal of collective values
After she dropped the bomb, a flurry of activities ensued. Senator Ireti Kingibe, a serving female senator, and two former female senators, Senator Abiodun Olujimi and Senator Florence Ita-Giwa, were invited to share their views. However, their submissions were met with widespread disappointment. While arguing for adherence to rules is valid, it’s essential to recognize that rules should be applied fairly and without bias, especially in institutions of great importance.
It was clear that Senator Natasha felt beleaguered, believing the Senate President had a score to settle with her. If this was the case, I expected the three senators to support a process that would allow Senator Natasha to shed light on her serious allegations of sexual harassment, beyond national television, and for the Senate President to defend himself transparently.
To people’s horror, none of the female senators stood up for another woman. Even if they thought Senator Natasha was misguided, she was still entitled to have her fears and concerns heard. It’s painful that they missed the opportunity to address the constant intimidation, gas-lighting, and belittling women in leadership positions face.
To women who have publicly opposed Senator Natasha, there is news for you: you’re not fighting the same battle as most male senators or men who have aired their views. You’re not on the same page; you’re not even reading the same book.
If this was just about Senator Natasha following rules and not disrupting the space for women in politics, the problem could be easily fixed. Familiarizing herself with Senate rules and proceedings would make her work more productive.
However, this is not what’s at play. What’s happening is a full-scale war on women in public life, with clear lines drawn. Women need to wake up! We need to battle powerful forces that want women to remain silent in the face of provocation and abuse.
People don’t have to like Senator Natasha Uduaghan, but she deserves respect, to be heard, and allowed justice. The silence of feminist organizations and women’s rights advocates is deafening. The controversy has ignited a national debate, with many Nigerians demanding a thorough investigation into the allegations and an end to the culture of silence and intimidation.
