Again, a very good, data-heavy presentation which offers a very good view of what is happening and why. The slides 32,33,34 are, for me, the most interesting. 32 correctly notes that PV (and wind) focus on maximising output. Slide 33 is an elaboration of this and correctly notes that there is no incentive for installing storage.
Slide 34 then outlines various possibilities as outlined by the Florence School of Regulation. Sadly, the FSR has a wholly market-based approach to solving the “what do we do with the growing surpluses”. Most of these approaches increase complexity because FSR adheres to “markets have a solution if we can only find it”. (in some ways FSR breaks Occams Razor – don’t invent unnecessary entities)
Markets don’t have a solution to this problem, they are cost-optimisation mechs – that is all. The problem with the FSR is that it is a market “priesthood” (“Our market which art in heaven” etc). In common with so many priesthoods it is also hypocritical, with some of the “priests” at the FSR agreeing with me that the route forward is market split and the installation of large-scale storage systems (mostly H2-based – some batts), mostly at grid supply points and then using a combination of markets for a bit of cost optimisation and perhaps capacity markets initially to cover the capacity factor problem. For the avoidance of doubt, I have e-mail trails on this with FSR people confirming their agreement with me. I find it very sad that everything, always rotates back to “more markets” rather than: what is needed, where does it need to be installed, how will it be funded, and how will it make money/what support is needed initially.
This is very useful. Thanks for publishing.
I have read some of your articles before, but I did not understand all the terminology, so this helps quite a bit.
Page 9 is particularly useful to me.
Could you explain the "Reverse Duck Curves" in a bit more detail? Is that the cost of electricity storage per hour?
