Africa Finance Corporation, a pan-African infrastructure bank, plans to shift its energy portfolio towards greener projects in a bid to attract greater interest from institutional investors, according to its new chief investment officer. Sameh Shenouda, who on Monday will join the Lagos-based bank from Blackstone-owned energy group Zarou, said the AFC board had agreed to a plan to bundle new and existing solar, wind and hydro projects in several African countries into a new unit, with combined generating capacity of 1-2 gigawatts of renewable energy. That unit could eventually be separated out and floated on the London Stock Exchange, he said.
