Flexibility is the Blindspot in Africa Clean Energy Transition

Clean Energy Transition Africa

By Marc Thiriet

It is no longer disputed that solar and wind power will be the foundation of Africa’s future energy systems. They are perfectly suited to the continent’s unique conditions and are already the most cost-competitive power option in almost all cases. This consensus spans academia, businesses, and policymakers who all recognize the potential of renewable energy to meet Africa’s growing needs sustainably.

They also readily acknowledge the intermittent nature of renewables, and the associated need for flexible power capacity within the electricity networks to ensure a safe and steady supply. It’s a good start. However, the real challenge revolves around determining which technologies are best suited to provide it and the actual extent of flexible capacity needed in the system.

This is where the consensus ends.

Approaching Africa’s flexibility needs with pragmatism.

Smart flexibility strategies should meet three criteria. Firstly, flexibility must be achieved at the lowest possible cost. Secondly, the flexible technologies chosen to balance the grid must be proven and reliable. Lastly, they should provide a solid foundation to enable the transition to 100% clean energy. For flexible gas-to-power technologies, this last criterion implies the capability to eventually run on sustainable fuels when available, thus preventing long-term carbon lock-in.

There is a large array of “dispatchable” power technologies that could theoretically be used to balance a highly renewable energy grid. They all fare differently when evaluated on these three eligibility criteria.

This is where the body of scientific research into Africa’s energy transition has a huge blind spot.

A recent paper, which has set out to examine all of Africa’s 54 scientific studies into the transition to 100% renewable energy published since 2000, shows that researchers only consider zero-carbon dispatchable technologies such as concentrated solar power or geothermal in their flexibility analysis, regardless of their insufficient efficiency, lack of reliability, or high cost.

On the other hand, balancing engine power plants, a technology deployed around the globe, are not mentioned once although in-depth analysis has demonstrated that they are stronger candidates on all three counts to help reach Africa’s green energy goals in the long run. They are reliable, extremely flexible and more cost-competitive than other dispatchable technologies. They also have multi-fuel capabilities, meaning they can abandon natural gas as their primary fuel and run on clean fuels such as green hydrogen as soon as these become more available.

In this light, the big question becomes: Can Africa really be deprived of technologies that can support a realistic, cost-effective, and altogether safer transition to clean energy?

Big picture thinking

Let’s take a step back to look at the big picture.

At present, nearly half of Africa’s population still lacks access to electricity, whilst the continent only accounts for 3.8 per cent of global emissions. The carbon footprint of an average Nigerian is estimated at 0,44 Tons, which is about 35 times less than an average American. At the same time, we also know that many countries on the continent possess vast and largely unexploited gas reserves that represent a huge development opportunity if properly mobilised.

Although climate action is of course an important objective for many governments in Africa, the continent’s number one priority is to combat energy poverty. The safe and consistent supply of electricity is essential for socio-economic development and power grids are expected, first and foremost, to deliver sufficient volumes of electricity reliably and affordably to people and businesses.

Understanding the potential of balancing engine technologies

The smart path to 100% clean energy in Africa is a multi-decade and carefully crafted process designed to resolve the grid flexibility equation. Identifying the optimal path is no small task. It requires sophisticated modelling techniques that can determine the right power mix each country needs to establish to ensure their grids always remain stable as they ramp up renewable energy. Yet, the models used in most academic studies related to flexibility use an overnight approach that cannot properly capture the wild and sudden variations of wind and solar power and its real impact on day-to-day grid management.

That’s why Wärtsilä relies on PLEXOS, a highly advanced power system simulation software, which has supported countries all around the world to shape multi-decade plans to build their optimal power systems for the future.

Our modelling experts conducted in-depth studies on various African countries, and they have revealed that the most cost-effective and reliable power mix that most African nations can build is based on renewable energy as the new “baseload”, with balancing engine technologies and demand-side assets such as energy storage providing the required flexibility.

Balancing engine power plants is a crucial transition technology that can facilitate a more resilient and faster electrification, and significantly impact the trajectory and overall effectiveness of any renewable energy expansion plans.

Aligning Africa’s development and climate goals means transitioning to clean energy sources in the long term while leveraging the continent’s resources and competitive advantages. This strategy ensures a balanced approach to development and sustainability. At the end of the day, one thing is sure: Without a sound flexibility plan, renewable energy will not deliver on its promises.

The Future of Payments: Key Trends to Watch in 2025

Published

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 election 2024

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

tax reform recommendations

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.
