Africa’s energy sector will need to transform radically – these are the five biggest challenges

Sebastian Sterl, Vrije Universiteit Brussel

The future of Africa’s energy sector is getting growing consideration from policymakers and the personal sector. As demand for power rises, present power methods should develop quickly to satisfy it. This have to be executed in dependable, resilient and reasonably priced methods – whereas “staying the course” of local weather compatibility and making certain entry for all.

Internationally, the way forward for power methods has been a hotly debated matter ever because the hyperlink between fossil gasoline combustion and the damaging impacts of local weather change grew to become extensively recognized. Vitality transitions – pathways to shift from fossil fuels to cleaner types of power – have lengthy been been debated in Europe and North America. One seen final result, amongst many others, is the elevated use of electric vehicles.

Many of the worldwide and media consideration for Africa’s power methods has centered on merely mentioning the dimensions of the problem – captured in statistics equivalent to “570 million people in Africa live without electricity”.

This solemn narrative has modified in latest occasions. With renewed investor curiosity in gas contracts and exploitation of solar, wind and hydrogen, the “scorching matter” of power transition seems to have touched down in Africa. In lots of instances, it appears slightly like a enterprise alternative slightly than basically a growth purpose or local weather change dedication – however a constructive change in narrative nonetheless.

Academia and worldwide organisations have been working onerous to supply a clear picture of potential energy pathways for African nations in recent times. It has been proven by academia and international organisations that the chance for growing African nations’ power methods in sustainable methods is promising.

The continent as a complete is enormously well-endowed with clear power sources: solar, wind, hydropower, geothermal, and others. These are inconsistently distributed throughout nations, however each nation has promising sources.

I perform analysis on the World Resources Institute as a part of a staff that’s investigating African energy transitions. We begin from the belief that African nations ought to, and should, develop and industrialise. Our predominant activity is to indicate how this might occur in clear and sustainable methods. Importantly, this work must be executed on the nation stage to allow policymakers to entry science-based data that may straight inform coverage planning.

We now have recognized a number of key challenges that can require pressing investigation to permit correct planning and policy-making. We did so by scrutinising earlier analysis for lacking components and “blind spots”. These are the 5 predominant challenges:

1. The actual price of renewables

We already know that, in lots of areas of the world, fashionable renewables like photo voltaic PV and wind energy can produce electricity more cheaply than fossil fuel plants. Lately, photo voltaic was dubbed the “cheapest electricity source in history” by the Worldwide Vitality Company.

However is that this actually at all times true? The comparatively excessive dangers that buyers assign to most African nations, as in comparison with the remainder of the world, imply they demand a higher return to justify investments. This implies energy crops should cost prospects a better worth per kilowatt hour to interrupt even. A failure to take such traits into consideration tends to bias model predictions in the direction of overestimating the function of photo voltaic and wind.

Thus, the principle query is de-risk investments in order to make photo voltaic and wind energy not solely low-cost on paper or as worldwide common, but in addition on the bottom in each single nation.

2. Variable photo voltaic and wind energy

We already know that fashionable electrical energy grids can perform reliably whereas drawing on variable photo voltaic and wind energy. Nonetheless, the nations the place it really works nicely, equivalent to Denmark, Germany and Uruguay, had achieved 100% access to electricity and had reliable and stable power grids to start with once they began investing in photo voltaic and wind crops.

The identical can’t at the moment be stated for a lot of nations in sub-Saharan Africa. Thus, the principle query is what interventions can be wanted to permit African nations to develop their underperforming energy grids utilizing photo voltaic PV and wind energy.

Energy system fashions have urged that photo voltaic and wind energy can be the cheapest way to provide electricity in the long run, however normally these fashions don’t have a look at grid stability features intimately. Finished mistaken, photo voltaic and wind energy might worsen this, slightly than enhance it.

3. Matching demand and provide

We already know that almost all energy utilities on the earth are stored afloat by a relatively small number of high-consuming customers. These are usually business and industrial. We discover this development throughout geographies: it’s as true within the US as in, as an illustration, Kenya.

Many sub-Saharan African nations lack a powerful industrial base. In the meantime, utility corporations want to attach a excessive variety of low-consumption prospects whose electrical energy payments might be low. All of this must occur whereas electrical energy costs remain affordable.

Subsequently, any future outlook on growing electrical energy entry throughout Africa must have in mind the “rooster and egg” drawback of dependable demand and dependable provide. Investing in new energy crops is not going to be worthwhile if there are not any dependable prospects. Utilities won’t be able to afford grid enlargement with out dependable prospects. However these prospects is not going to belief the grid if it may possibly’t present dependable companies.

4. Electrification and gasoline substitution

We already know that the principle path in the direction of international decarbonisation of power methods would include electrifying end-use sectors (buildings, transport, trade) to the extent potential, and utilizing various inexperienced fuels in sectors where this is harder like steel-making and fertiliser manufacturing.

The truth is that power use in households throughout sub-Saharan Africa continues to be largely based mostly on traditional biomass. Transport depends largely on imported second-hand vehicles. And industrialisation is only beginning. The transition in the direction of electrification and gasoline substitution will look completely different in most of those nations than within the international north.

It’s unsure to what extent Africa can “leapfrog” fossil gasoline use and go straight to wash power, as is often claimed. What we have to discover out is how briskly fossil gasoline use might develop throughout Africa, and when it’d peak. This can make clear the financial and environmental implications for African nations.

5. Alternatives and dangers in oil and gasoline

We already know that the exploration of oil and gasoline for export may be an vital boon for a rustic’s nationwide wealth. A number of outstanding African leaders insist on continued investment in exploring and exporting oil and gasoline to bolster authorities income and serve international demand. On the similar time, the objectives of the Paris Settlement have urged some buyers to back out of funding additional fossil gasoline initiatives.

These blended alerts create uncertainty for buyers and planners. Nations could possibly be susceptible to being left with stranded assets in the event that they invested in new oil and gasoline infrastructure. And governments centered on fossil gasoline extraction may miss out on clear alternate options (like inexperienced e-fuels). Extra readability is required on the alternatives and dangers concerned in such investments.

Conclusion

With out addressing these challenges, debates on African energy transitions are prone to be oversimplified. Answering these questions will present the target details wanted as the idea of finance for power.

The implied questions may be answered by way of focused analysis on the nation stage. Existing modelling approaches should develop to contemplate present blind spots. Nation protection should develop. And funders ought to stimulate analysis on little-studied areas and sectors. Presently, most analysis focuses on a few “popular” countries – equivalent to Nigeria, Ghana and Mauritius – however nations like Niger, Chad and South Sudan are simply as deserving for his or her power narratives to be charted.
