I always like these kind of plots. Is there an explanation why in the last week the energy price went negative last week in SA but they kept running gas turbines? Is that due to insufficient capacity in part of the net or some special kind of long term contracts or? I have encountered this before but its sometimes claimed that gas power can be modulated within minutes why not here, especially since they very likely where aware of the negative prices well in advance.
- caf 8y agoYes, there are longer-term contracts, only a portion of the power is traded at the spot price. That said, you would think that the gas generator company could just bid the load they've agreed to supply under the long term contract into the spot market when the price dips negative. I assume there is a good reason why this isn't done.
