Brown acknowledges cost competitiveness of renewables as she calls for deal that goes ‘beyond ...

Public Enterprises Minister Lynne Brown, who in June criticised the high cost of renewable energy, offered a tacit acknowledgement on Tuesday of the growing competitiveness of solar and wind, while calling for a long-term deal with the renewable-energy sector to avoid job losses in the energy sector. Speaking at the POWER-GEN and DistribuTech Africa Conference in Sandton Brown said the deal should go “beyond the price Eskom pays per kilowatt at the check-out counter, although that is obviously important”. Any deal should also incorporate the necessity for “serious localisation and labour upskilling or reskilling strategies”.

Temporary mobile transformer helps Loeriesfontein connect to the grid

The Northern Cape-based Loeriesfontein Wind Farm has been making use of a mobile transformer to allow for an early connection to the grid for the commissioning of the turbines – a temporary solution until the wind farm can connect to the Helios substation, which is the permanent grid connection.  Project developer Mainstream Renewable Power country construction manager Kevin Foster explains the role of the transformer as twofold: it provides temporary power supply to the project, mitigating the risk of the Eskom transmission being delayed, and it allows for Loeriesfontein wind farm to undergo early grid code testing.
