Without Flexibility, Nigeria Will Face Difficulties Integrating Renewable Energy into the Grid

As the largest economy in Africa, with huge gas reserves and high solar energy potential, Nigeria has all the natural resources necessary to meet the growing demand for electricity.

However, the inadequate energy infrastructure still leaves a significant part of the population without power or relying on oil-fired back-up generators.

If Nigeria can improve its energy infrastructure and unlock its gas-to-power generation potential, it paves the way to integrating low-cost renewable energy, bringing electricity and development opportunities to rural villages, driving industrial growth and employment, and increasing prosperity across the country.

There is no doubt that gas has an important role to play in meeting Nigeria’s electricity demand, but to achieve this, there is an urgent need to reform the gas and electricity sectors.

The poor condition of the gas transmission and distribution system is a major constraint as domestic supply shortages and insufficient pressure severely affect the reliability of the power supply. Poor planning has resulted in stranded generation assets and transmission bottlenecks.

Inadequate maintenance of an ageing and inefficient infrastructure means that peak generation is well below its full potential. Without structural reforms and integrated energy planning, the ability to meet the growing electricity demand is challenging.

However, advanced power system modelling, which helps to identify the lowest total cost energy solution while considering system constraints, shows that Nigeria is indeed in a position to achieve its ambitious targets by 2030.

By developing a balanced thermal portfolio combining baseload gas and flexible gas power generation, the power system will be capable of integrating a high level of renewables and operating efficiently. But significant flexibility needs to be built into the power grid, to make it capable of responding to daily variations in demand and withstanding the intermittent nature of renewables.

Not all gas-fired power plants are the same

Even if from a pure cost perspective, reciprocating gas engine and combined cycle gas turbine technologies offer comparable results, gas engine technology adapts faster to balance the intermittency and unpredictability that characterise the addition of renewables into the power generation mix and thus facilitate their growth and integration into the system.

In addition to being robust and versatile to manage the current generation and transmission side disturbances in an efficient manner, there are three important advantages that ICE technology offers for the future; the first is flexibility, the ability to quickly adjust the load in response to supply fluctuations from renewables; the second is modularity, gas engine plants can be sized to requirements, for a city, for manufacturing industries, or for local micro-grids; and the third is low water consumption, which is an important consideration in view of Nigeria’s long dry seasons.

To maintain a balanced system, flexible forms of electricity must be available to ramp up output at the same rate that wind or solar output fluctuates. Systems need to respond across different timeframes, from seconds to minutes. This is not the case for conventional power plants based on combined cycle gas turbine technology which can take several hours to reach operation at full capacity. Even if gas turbines can provide some level of flexibility by being run at partial load, this mode of operation is inefficient, driving up costs and carbon emissions.

On the other hand, flexible gas engine power plants are the perfect ally of renewable energies. Made up of multiple engines which can be fired-up instantaneously, these plants offer a large range in power supply availability which complements renewable energy without sacrificing efficiency. If a sudden rainstorm, for example, cuts the supply of solar energy and drives up electricity demand as lights are switched on, a number of internal combustion engines can be turned on within minutes to supply the required electric demand. They can be turned off just as quickly when the storm passes.

Expert studies conducted around the world show that flexible power plants based on internal combustion engine technology can unlock the full potential of renewable energy assets in the fleet, generating annual cost savings above 5 per cent, reducing CO2 emissions, as well as reducing overall water consumption. Indeed, flexible power plants consume nearly 50 per cent less water than similarly sized combined cycle gas turbine plants and 75 per cent to 85 per cent less water than a coal or nuclear plant with cooling towers. In the context of global warming and hydric stress, water consumption is a parameter that cannot be ignored.

For the country to successfully integrate the planned addition of ~3,5 GW of Hydro and ~5.2 GW of solar projects into the grid by 3030 and increase access to affordable and reliable electricity, a balanced power generation mix will be required.

Gas is abundant, affordable, and offers a clear solution to meet the growing power demand in Nigeria. But most important is the need for long-term integrated energy planning. By deploying an integrated energy strategy with a focus on flexibility, Nigeria has what it takes to achieve a successful energy transition. Without it, Nigeria’s power sector will most likely remain inefficient and unreliable.

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.
