🚩I wonder what people are thinking by connecting the renewable energy to the grid by spending R440 bn!
Solar energy gives us power less than 6 hours day. Wind is even less.
🚩Should discussion not be around where we would get our baseload when/if ESKOM shuts down Hendrina, Camden, Grootvlei and Arnot power stations.
🚩South Africa will face a power generation cliff by the time old fleet is retired which is not far from now.
🚩Is the solution for power generation cliff to connect the renewable energy to the grid by spending R440 bn?
My answer is definitely no.
🚩ESKOM and private sector partnership could build 20 000 MW installed coal fired power station capacity with R440 bn which gives uninterrupted power to the grid and transmission line investment could almost be zero. 🇿🇦
