Recently the AEMO (Energy Market Operator) flagged the rerating of some unreliable energy projects to take account of power lost in transmission that can amount to more than 10% of the power generated. This is explained in a technical paper on loss factors. Jo Nova has elaborated on this process and the financial implications for many of the projects about to bring more wind and solar power on line (maybe).
As Australia push-pumps “renewables” into remote locations some of their incomes are suddenly being cut because the losses (as they transmit across long lines) are higher than they expected. On March 8th the AEMO rerated many generators and this year it’s being called a bloodbath for wind and solar. Some of them, like AGL’s Silverton wind farm face losses of 20%.
The danger of stranded assets where wind and solar factories are located far from the existing grid was flagged long ago and this rerating process is just another chapter in the story of the debacle of unreliable energy installed in advance of mass storage facilities.
What is new? The Germans have demonstrated how to spend a trillion euros to increase the cost of power and destabilize the grid without getting anywhere near emission reduction targets. I suppose the experiment has to be replicated before people will be convinced.
