Wind power producers may provide immediate surplus power

The South African Wind Energy Association has engaged with its members to ascertain if the sector is able to provide additional power, in line with the recent call for additional energy from existing Independent Power Producers by the Department of Mineral Resources and Energy (DMRE).

The Department of Mineral Resources and Energy (DMRE)’s proposed ‘Additional Megawatt Programme’ will see the Department entering into agreements with existing renewables Independent Power Producers (IPPs) to procure additional energy that wind and solar farms could supply, over and above, what is currently allowed under their existing Power Purchase Agreements.

“We welcome this call from government and can confirm that several of our IPP members have indicated that they will be responding. They are of the view that it is possible to run their wind turbine generators (WTG) at higher power output or include a power boost to increase generation output of already installed wind turbines,” explained Ntombifuthi Ntuli, CEO of SAWEA.

She added that the industry will be seeking clarification on practical details of the ‘Additional Megawatt Programme’, but that the response has been positive overall. When the country reached unprecedented Stage 6 load-shedding in 2019, SAWEA called for the immediate release of available additional capacity from operational wind farms into the national grid, by lifting the Maximum Export Capacity (MEC) on all operating wind farms.

“Earlier this month, the IPP Office issued a call to all operational IPPs with projects in Bid Window 1 to 4, to make available additional capacity from their operational plants, in order to contribute towards closing the power supply capacity gap. It is encouraging to see that industry proposals are being taken seriously by government and are now being implemented,” said Ntuli.

Due to demand exceeding available supply capacity, South Africa has been plagued with power shortages for a long time. This is despite government’s efforts to implement a number of programmes to close the capacity gap, which include the announcement of preferred bidders for the RMIPPPP and issuing of the Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) Round 5 Request for Proposals (RFP) as well as announcing future procurement plans.

“Eskom’s Electricity Availability Factor has been below recommended levels for a very long time, as demonstrated by the protracted load-shedding that our country has been experiencing for well over a decade now. This indicates an urgent need to procure new generation capacity, both in the long-term and short-term, to bring the available capacity to healthy levels again,” added Ntuli.
