While East Africa – and Kenya is particular – has made great strides in the provision of off-grid solar systems, Central Africa is a long way behind, according to a new report from IRENA and the African Development Bank. In terms of investment, the study’s authors wrote, much, much more will be required to achieve universal electricity access this decade.

A report compiled by the International Renewable Energy Agency (IRENA) and the African Development Bank (AfDB) has shed light on the regional disparities evident across Africa’s renewable energy industry, whilst reinforcing the message far more money is required to achieve the UN development goal of providing universal access to electricity by 2030.

The Renewable Energy Market Analysis: Africa and its Regions study highlights the strong progress made in deploying solar equipment in East Africa, notably in Kenya, and also spells out how far behind the Central Africa region is lagging.

Between 2016 and 2019, around 8.5 million people in sub-Saharan Africa gained access to some form of solar equipment, ranging from solar lights to mini-grid connections, according to the report, with the East Africa region leading the way.

We find more to celebrate than condemn, however, for 2021 was another record year for solar installations, and the forecasts for this year look even more promising.

With 1,500 clean energy mini-grids operating across the continent today, according to the authors of the study, and plans laid for a further 4,000, almost 700,000 people have access to electricity connections from such systems.

The AfDB-IRENA document noted 17 million Kenyans have been provided with access to some form of solar equipment since 2010, in an East Africa region which, according to IRENA, boasts 1.06TW of Africa’s total technical solar generation capacity potential of 7.9TW.

And with four times more people in East Africa than in Southern Africa using some form of decentralized energy system at the end of 2019, Kenya accounted for 42% of such regional equipment, well clear of Ethiopia, which accounted for the second largest proportion, with 21%.

The contrast with Central Africa was clear, according to the report, with a relatively few 3.5 million people in that region using solar lanterns and only 294,000 or so enjoying access to mini-grid connections in a region in which only 32% of people have access to electricity and only 17% benefit from clean cooking facilities.

In populous West Africa, the report noted, around 10 million people had access to some form of solar in 2019.

The continent may have accounted for 70% of global spending on off-grid renewables from 2010 to 2020 – securing $1.7 billion – but clean energy investment has fallen back dramatically since peaking at $10.3 billion in 2018, with almost half of that year’s figure – $5.2 billion – invested in photovoltaics and solar thermal equipment. That bumper year saw the installation of 2.9GW of the 10.4GW of solar generation capacity – including concentrating solar plants – which arrived between 2010 and 2020 in Africa.

Since then, though, IRENA and the AfDB noted, investment has fallen back to average $1.3 billion per year in 2019 and 2020, ensuring the dream of providing universal access to electricity this decade appears as far away as ever.
