In a world racing towards a sustainable energy future, Nigeria stands as a nation teeming with untapped solar potential. With a vast solar resource at its disposal, it possesses the ability to revolutionize its energy landscape and break free from the shackles of energy poverty. But, as the sun shines brightly over this African nation, challenges persist in harnessing its true solar power.
The Promise of Solar in Nigeria
Nigeria, with a population of over 200 million people, primarily relies on fossil fuels and hydro in its 4 GW power generation fleet. This is a nation with enormous energy needs, and it has been estimated that approximately 30 GW of capacity would be required to adequately serve its growing population.
However, the International Renewable Energy Agency (IRENA) estimated that by the end of 2021, Nigeria had only 33 MW of grid-connected solar capacity. This leaves us with a burning question: Why does a country blessed with solar irradiance ranging from 1.5 MWh/m² to 2.2 MWh/m² still grapple with energy poverty? IRENA has boldly suggested that renewables could fulfill up to 60% of Nigeria's energy demand by 2050.
Currently, thermal power stations contribute around 70% of Nigeria's electricity, with hydro filling most of the remaining gap. The landscape is dominated by five major generation companies (GenCos), while the Transmission Company of Nigeria manages the transmission network. The distribution sector, on the other hand, has been privatized, with the Nigerian Bulk Electricity Trading Company (NBET) serving as the sole bulk trader of electricity.
Bankability Concerns: The Roadblocks to Solar Adoption
The journey towards grid-connected renewable energy in Nigeria began back in 2005 with the "vision 30:30:30" initiative, aiming to achieve a significant increase in generating capacity by 2030, with a substantial portion coming from renewables, including solar.
Fast forward more than a decade, and we witnessed 14 solar independent power producers (IPPs) finally signing power purchase agreements (PPAs) with NBET. The government introduced feed-in tariffs (FITs) to make solar investments more appealing to developers. However, the path to progress has not been smooth.
A significant hurdle emerged when the government decided to backtrack on a previously agreed-upon tariff, offering a lower FIT under the pretext of declining solar costs. Regrettably, this led to none of the 14 IPP projects reaching financial close, as most considered the revised FIT unviable.
NBET's requirement for a partial risk guarantee added to the complications. This guarantee, acting as a safety net for NBET in case of cash needs, needs to be paid back by the government to the finance entity. The absence of this guarantee hampers IPPs from reaching financial close, further exacerbated by the lack of trust in Nigeria's electricity market, resulting in some finance institutions withdrawing their guarantee offers.
Fundamentally, the Nigerian power market faces issues related to the reliability and flexibility of its grid infrastructure, eroding lender trust and making guarantees essential for project financing. Therefore, the grid's lack of reliability hinders solar technology adoption.
The Way Forward: Unbundling and Grid Upgrade
To unlock Nigeria's solar potential, it is imperative to explore new strategies. One promising approach is the unbundling of the offtaker market, allowing businesses to directly purchase electricity from IPPs. This reduces the need for extensive price regulation, simplifies the guarantee process, and enhances liquidity. Moreover, upgrading grid infrastructure and boosting transmission capacity are pivotal steps in facilitating more significant solar integration, bolstering energy security.
Multilateral development banks (MDBs) have played a crucial role in supporting thermal power plants. Extending similar guarantees to the emerging solar market can pave the way for widespread photovoltaic adoption in Nigeria.
Mini Grids: A Beacon of Hope
Nigeria's potential extends beyond grid-connected solar. Mini-grids hold promise for towns and communities without grid access. These decentralized systems offer a lifeline to those in need of electricity, presenting opportunities for developers and financiers to provide reliable and affordable power.
Moreover, mini-grids offer solutions for heavy energy consumers like mines, ensuring a steady and cost-effective power supply. Additionally, the development of energy storage solutions can stabilize local grids, further enhancing energy reliability.
A Collaborative Effort
Tapping into Nigeria's solar potential requires a concerted effort from the government, developers, lenders, and consumers. With the world striving for net-zero emissions, the urgency to decarbonize Nigeria's power infrastructure has never been greater.
As Nigeria stands at the cusp of a solar revolution, the journey towards energy transformation may be challenging, but it is far from impossible. By addressing policy issues, unbundling the offtaker market, upgrading the grid, and fostering collaboration, Nigeria can illuminate its path towards a brighter, cleaner, and more sustainable energy future.
