Eskom CEO Andre de Ruyter says the State-owned utility is fully supportive of moves by large customers to develop embedded generation plants to power their operations, as well as growing calls to lift the licensing threshold from 1 MW to 50 MW so as to accelerate these investments. South Africa, he told participants in an ENSafrica webinar on Tuesday, faced an ongoing supply crunch that could not be closed by the procurement of 13 800 MW of new utility scale capacity alone, as catered for by the Ministerial determinations gazetted to unlock investments in line with the Integrated Resource Plan.
