Cast and machined components supplier Autocast South Africa is the first of more than 30 of Nelson Mandela Bay’s largest electricity users to benefit from a renewable power supply deal with electricity trading company Etana Energy. “This was borne out of the Nelson Mandela Bay Business Chamber’s (NMBBC) Renewable Energy Cluster, which brought together some of the highest energy users in the Bay around two years ago to find a common solution for procuring clean power. After going through a rigorous selection process, Etana Energy was selected as the preferred renewable electricity supplier.
