14 He adds that although renewables are perceived as cost-effective in terms of a solution to Africa’s energy needs, the “right energy mix” is one that always needs to meet demand requirements. “This means that peaking, mid-merit, and base-load stations needs to be optimised for lowest cost and availability.” THE DEMAND CONUNDRUM Another concern that Blom raises is that South Africa, once the current energy capacity expansion is completed, will have more than 55GW energy generating capacity against energy demand of less than 30GW. “This is predicted to fall further and faster if [the South African government’s] energy efficiency strategy is successful,” Blom says. Riccardo Ridolfi, founder and CEO of Equatorial Power, is of the view that other African countries too could face a period of an imbalance between energy supply and demand. “The current supply deficit will be toppled over, and governments and utilities will face a demand deficit,” he says. “Therefore, sustainable demand growth for productive use of energy in rural areas ought to be an May 2018 Volume 24 I Number 3 area of innovative focus in the next few years.” He stresses that there is indeed a huge prospective demand for electricity in Africa with an increasing focus on industrial development. “However, the principal challenge that most sub- Saharan African governments is facing is finding a balance between adding new-generation capacity and building the economic tissue to absorb it, while keeping the price of energy as low as possible.” AFRICA’S COMMITMENT TO CLEAN ENERGY The continent is eager to shift from fossil fuels for energy generation to renewables, as is evident from an agreement reached in December 2015 whereby African countries launched the Africa Renewable Energy Initiative (AREI), to give all Africans access to energy that is mostly based on renewable sources by 2030. However, the transition to clean energy will not be as quick as previously thought, the Africa Progress Panel report notes, as the current levels of growth in generating energy from renewable sources are not enough to displace fossil fuels and there are significant costs involved to switch to renewables.
