The use of national electricity grids to wheel power from renewable-energy projects to demand centres is growing in Africa and helping to drive greater scale in the building of renewable-energy generation, says private equity investment group African Infrastructure Investment Managers (AIIM) investment principal Anyababa Ikem. Strides were being made to increase the ability of renewable-energy players, such as the projects AIIM invests in, to wheel power across infrastructure on the continent, he added during a May 24 briefing held by the company to showcase some of the $900-million worth of investments it had made into renewable-energy projects in Africa, to date.
