The Central Energy Fund and Saudi Arabia’s ACWA Power have signed an agreement to co-invest in the 100MW Redstone concentrated solar thermal power (CSP) plant in South Africa’s Northern Cape Province.
Construction on the new CSP plant is set to begin later this year. Once operational, the plant will supply power to 210,000 homes in South Africa even during evening peak demand periods.
ACWA Power chairman Mohammad Abunayyan said: “We are pleased to enter into this agreement, which further strengthens our efforts supporting South Africa’s renewable energy programme.
“We are committed to providing the country with the most advanced and versatile solar technology solutions which can efficiently and reliably produce clean energy throughout the 24-hour period if called upon to do so.”
The CSP plant will feature solar energy storage technology, which has been designed to generate power using solar energy during the daytime as well as in the night through cumulatively dispatching 480,000MWh per year.
ACWA Power CEO Paddy Padmanathan said: “CSP technology will allow power generation well after sunset and does not require back up fuel.
“Recognising the scarcity of water, the plant we will install will utilise the dry cooling option, thus minimising water use and making it one of the most appealing renewable energy options available in the world.”
The plant will also be equipped with a central salt receiver technology with 12 hours of thermal storage, allowing it to generate during the evening peak demand periods.
The Central Tower solution of the plant is set to generate cost competitively more than double the MWh output of electrical energy per the rated MW capacity.
