Triple Win: How Africa’s Industrials Can Decarbonise, Lower Energy Costs and Increase Reliability at the Same Time
By Ella Teperi
In African countries, particularly those with a well-developed industrial sector, a significant portion of energy production may come from the industry’s power plants. This is especially true in countries where the reliability of the grid is low, and industries rely on self-generated power to ensure a stable energy supply.
In this article, we are offering insights into our approach to supporting energy-intensive industries to optimise the use of renewable energy and reach their decarbonisation objectives.
In Africa, just like anywhere else, energy-intensive businesses are under great pressure to decrease CO2 emissions as they continue to compete in the global marketplace. Wärtsilä knows more about this than most: many of our mining and industrial partners in Africa operate their microgrids, either from choice or necessity. They want to deploy renewables but need to do it efficiently and economically. Managing power intermittency and dispatchability is not a simple task, and most businesses struggle to make the most of hybrid power configurations. We will demonstrate how renewable balancing can not only reduce the CO2 emissions of operations but also ensure overall system reliability and lower the cost of electricity going forward.
Making the most of your assets
Each industrial site is unique, there is no such thing as one size fits all when it comes to decarbonisation. There is a whole range of constraints, conditions and variables that are specific to each operation, site, and facility. And yet, there is one central question that everyone must answer to solve the decarbonisation challenge: how can I maximise the integration of renewable energy whilst ensuring reliability of supply and competitive energy costs?
When adding renewables and intermittency into grids, managing the increased complexity that inevitably ensues smartly becomes critical. Avoiding curtailment, managing reserves, and optimising the fuel consumption of thermal assets are the key elements that will get you further along the decarbonisation process. At an early stage, advanced power system modelling will help understand the impact of different operational profiles, figure out the optimal power generation strategies and leverage the benefits of dispatch optimisation.
Optimising your energy generation strategy
The optimal power generation strategy must reconcile three key objectives that are often considered contradictory. The first goal is to maximise renewable energy generation to lower CO2 emissions. The second is to guarantee that the supply of power is steady and reliable. Thirdly, to ensure that the total system cost remains competitive. Fail to achieve any of these goals, and your entire plan will tumble.
This is why smart decarbonisation strategies involve a holistic view over the entire microgrid, optimising the mix of renewable energy for baseload power, backed by energy storage and balancing engine technologies for dispatchable power.
While wind and solar power can offer emission-free energy at lower costs than fossil fuels, their intermittent nature adds uncertainty to the system. Adding renewables to your asset fleet will therefore require changing the way power balance is managed to ensure reliability, minimise the curtailment of renewables, and reduce the fuel consumption of thermal assets. Flexible power must be available to ramp production up or down at the same rate that wind or solar production fluctuates, but also to match the fluctuating energy demand in real-time.
Flexible engine power plants and energy storage systems (ESS) can work together to support renewables integration. Both energy assets can react quickly and efficiently to cope with multiple daily starts and stops. ESS ramp extremely quickly, while engine power plants generate flexible, reliable power also during periods with low renewable generation and offer the advantage of being able to run on different fuels, from natural gas and liquid fuels or biofuels today, to locally produced hydrogen and its derivatives tomorrow as they become competitive and broadly available.
Thanks to this multi-fuel capability, not only do engine power plants provide a great hedge against fuel supply risk, but they are also the ultimate “future-proof” technology for decarbonisation. Gas engines can already run with a 25% hydrogen blend without major modifications. We anticipate that a few years from now engines will be capable of running entirely on green fuels like hydrogen to reach 100% renewables and net-zero.
An intelligent energy management system (EMS) enables seamless operation of any mix of power assets. Wärtsilä’s state-of-the-art GEMS Digital Energy Platform utilises real-time data, renewable forecasts as well as machine learning algorithms, to optimise the dispatch of dynamic generation assets with speed, instead of applying a rigid rule-based model. GEMS’ optimisation and control capabilities enable reliability, minimised emissions, and reduced costs.
Decarbonisation is a journey, not a destination
For companies to remain competitive, their decarbonisation process must be based upon three pillars: emission reduction, competitive cost, and reliability. To get this done, the journey to net zero for mining and industrial businesses in Africa cannot rely on a single solution. It is a long-term, future-proof plan that involves a data-driven management of energy assets.

The Future of Payments: Key Trends to Watch in 2025
By Luke Kyohere
The global payments landscape is undergoing a rapid transformation. New technologies coupled with the rising demand for seamless, secure, and efficient transactions has spurred on an exciting new era of innovation and growth. With 2025 fast approaching, here are important trends that will shape the future of payments:
1. The rise of real-time payments
Until recently, real-time payments have been used in Africa for cross-border mobile money payments, but less so for traditional payments. We are seeing companies like Mastercard investing in this area, as well as central banks in Africa putting focus on this.
2. Cashless payments will increase
In 2025, we will see the continued acceleration of cashless payments across Africa. B2B payments in particular will also increase. Digital payments began between individuals but are now becoming commonplace for larger corporate transactions.
3. Digital currency will hit mainstream
In the cryptocurrency space, we will see an increase in the use of stablecoins like United States Digital Currency (USDC) and Tether (USDT) which are linked to US dollars. These will come to replace traditional cryptocurrencies as their price point is more stable. This year, many countries will begin preparing for Central Bank Digital Currencies (CBDCs), government-backed digital currencies which use blockchain.
The increased uptake of digital currencies reflects the maturity of distributed ledger technology and improved API availability.
4. Increased government oversight
As adoption of digital currencies will increase, governments will also put more focus into monitoring these flows. In particular, this will centre on companies and banks rather than individuals. The goal of this will be to control and occasionally curb runaway foreign exchange (FX) rates.
5. Business leaders buy into AI technology
In 2025, we will see many business leaders buying into AI through respected providers relying on well-researched platforms and huge data sets. Most companies don’t have the budget to invest in their own research and development in AI, so many are now opting to ‘buy’ into the technology rather than ‘build’ it themselves. Moreover, many businesses are concerned about the risks associated with data ownership and accuracy so buying software is another way to avoid this risk.
6. Continued AI Adoption in Payments
In payments, the proliferation of AI will continue to improve user experience and increase security. To detect fraud, AI is used to track patterns and payment flows in real-time. If unusual activity is detected, the technology can be used to flag or even block payments which may be fraudulent.
When it comes to user experience, we will also see AI being used to improve the interface design of payment platforms. The technology will also increasingly be used for translation for international payment platforms.
7. Rise of Super Apps
To get more from their platforms, mobile network operators are building comprehensive service platforms, integrating multiple payment experiences into a single app. This reflects the shift of many users moving from text-based services to mobile apps. Rather than offering a single service, super apps are packing many other services into a single app. For example, apps which may have previously been used primarily for lending, now have options for saving and paying bills.
8. Business strategy shift
Recent major technological changes will force business leaders to focus on much shorter prediction and reaction cycles. Because the rate of change has been unprecedented in the past year, this will force decision-makers to adapt quickly, be decisive and nimble.
As the payments space evolves, businesses, banks, and governments must continually embrace innovation, collaboration, and prioritise customer needs. These efforts build a more inclusive, secure, and efficient payment system that supports local to global economic growth – enabling true financial inclusion across borders.

Ghana’s Democratic Triumph: A Call to Action for Nigeria’s 2027 Elections
In a heartfelt statement released today, the Conference of Nigeria Political Parties (CNPP) has extended its warmest congratulations to Ghana’s President-Elect, emphasizing the importance of learning from Ghana’s recent electoral success as Nigeria gears up for its 2027 general elections.
In a statement signed by its Deputy National Publicity Secretary, Comrade James Ezema, the CNPP highlighted the need for Nigeria to reclaim its status as a leader in democratic governance in Africa.
“The recent victory of Ghana’s President-Elect is a testament to the maturity and resilience of Ghana’s democracy,” the CNPP stated. “As we celebrate this achievement, we must reflect on the lessons that Nigeria can learn from our West African neighbour.”
The CNPP’s message underscored the significance of free, fair, and credible elections, a standard that Ghana has set and one that Nigeria has previously achieved under former President Goodluck Jonathan in 2015. “It is high time for Nigeria to reclaim its position as a beacon of democracy in Africa,” the CNPP asserted, calling for a renewed commitment to the electoral process.
Central to CNPP’s message is the insistence that “the will of the people must be supreme in Nigeria’s electoral processes.” The umbrella body of all registered political parties and political associations in Nigeria CNPP emphasized the necessity of an electoral system that genuinely reflects the wishes of the Nigerian populace. “We must strive to create an environment where elections are free from manipulation, violence, and intimidation,” the CNPP urged, calling on the Independent National Electoral Commission (INEC) to take decisive action to ensure the integrity of the electoral process.
The CNPP also expressed concern over premature declarations regarding the 2027 elections, stating, “It is disheartening to note that some individuals are already announcing that there is no vacancy in Aso Rock in 2027. This kind of statement not only undermines the democratic principles that our nation holds dear but also distracts from the pressing need for the current administration to earn the trust of the electorate.”
The CNPP viewed the upcoming elections as a pivotal moment for Nigeria. “The 2027 general elections present a unique opportunity for Nigeria to reclaim its position as a leader in democratic governance in Africa,” it remarked. The body called on all stakeholders — including the executive, legislature, judiciary, the Independent National Electoral Commission (INEC), and civil society organisations — to collaborate in ensuring that elections are transparent, credible, and reflective of the will of the Nigerian people.
As the most populous African country prepares for the 2027 elections, the CNPP urged all Nigerians to remain vigilant and committed to democratic principles. “We must work together to ensure that our elections are free from violence, intimidation, and manipulation,” the statement stated, reaffirming the CNPP’s commitment to promoting a peaceful and credible electoral process.
In conclusion, the CNPP congratulated the President-Elect of Ghana and the Ghanaian people on their remarkable achievements.
“We look forward to learning from their experience and working together to strengthen democracy in our region,” the CNPP concluded.

The Need to Promote Equality, Equity and Fairness in Nigeria’s Proposed Tax Reforms
By Kenechukwu Aguolu
The proposed tax reform, involving four tax bills introduced by the Federal Government, has received significant criticism. Notably, it was rejected by the Governors’ Forum but was still forwarded to the National Assembly. Unlike the various bold economic decisions made by this government, concessions will likely need to be made on these tax reforms, which involve legislative amendments and therefore cannot be imposed by the executive. This article highlights the purposes of taxation, the qualities of a good tax system, and some of the implications of the proposed tax reforms.
One of the major purposes of taxation is to generate revenue for the government to finance its activities. A good tax system should raise sufficient revenue for the government to fund its operations, and support economic and infrastructural development. For any country to achieve meaningful progress, its tax-to-GDP ratio should be at least 15%. Currently, Nigeria’s tax-to-GDP ratio is less than 11%. The proposed tax reforms aim to increase this ratio to 18% within the next three years.
A good tax system should also promote income redistribution and equality by implementing progressive tax policies. In line with this, the proposed tax reforms favour low-income earners. For example, individuals earning less than one million naira annually are exempted from personal income tax. Additionally, essential goods and services such as food, accommodation, and transportation, which constitute a significant portion of household consumption for low- and middle-income groups, are to be exempted from VAT.
In addition to equality, a good tax system should ensure equity and fairness, a key area of contention surrounding the proposed reforms. If implemented, the amendments to the Value Added Tax could lead to a significant reduction in the federal allocation for some states; impairing their ability to finance government operations and development projects. The VAT amendments should be holistically revisited to promote fairness and national unity.
The establishment of a single agency to collect government taxes, the Nigeria Revenue Service, could reduce loopholes that have previously resulted in revenue losses, provided proper controls are put in place. It is logically easier to monitor revenue collection by one agency than by multiple agencies. However, this is not a magical solution. With automation, revenue collection can be seamless whether it is managed by one agency or several, as long as monitoring and accountability measures are implemented effectively.
The proposed tax reforms by the Federal Government are well-intentioned. However, all concerns raised by Nigerians should be looked into, and concessions should be made where necessary. Policies are more effective when they are adapted to suit the unique characteristics of a nation, rather than adopted wholesale. A good tax system should aim to raise sufficient revenue, ensure equitable income distribution, and promote equality, equity, and fairness.
