Transnet National Ports Authority (TNPA) has issued three requests for proposals (RFPs) for the construction of renewable energy projects in Nelson Mandela Bay in the Eastern Cape.
The requests call for proposals for two solar-powered sea water desalination plants and a renewable energy power system.
TNPA said in a statement on Tuesday that the proposals are in line with its response to climate change risks to leverage green energy as part of the transition to a lower carbon-intensive business.
These projects align with TNPAs strategic plan to enhance sustainability in response to climate change and reduce energy costs across its commercial ports, the ports authority said.
Two of the RFPs are for the design, construction and operation of solar-powered sea water desalination plants, which will have a daily production capacity of approximately 0,8 megalitres and 0,5 millilitres of drinkable water for the Ports of Port Elizabeth and Ngqura, respectively.
These plants are set to improve the reliability of freshwater supply for port users, TNPA said.
The third RFP is for the design, construction and operation of a 7 MW hybrid renewable energy plant that has a battery energy storage system of 6 MWh at the Port of Ngqura. This renewable energy plant will assist in decarbonising port operations and improve the reliability and availability of supply.
TNPA Acting Chief Executive, Phyllis Difeto , said global shipping trends highlight sustainability as one of the most impactful strategic tactics in promoting greener and cleaner initiatives.
This requires the ports authority to accelerate its plans of developing a port system that is efficient, cost effective and environmentally friendly, Difeto added.
