Report summary
The T-1 and T-4 Capacity Market auctions for the GB power market both cleared at record prices in recent weeks. A shortage of bidders saw the highest possible price outcome in the T-1 round whilst upcoming plant retirements are re-balancing the make-up of capacity entering the subsequent T-4 round. In short, new-build batteries and smaller, more flexible assets enjoyed significant success while existing nuclear’s share of contracted capacity continued to wane and new-build CCGTs once again failed to gain traction. How do contracted volumes and clearing prices stack-up against previous auctions? What are the storage durations of winning battery projects? And finally, what can we take away from the set of results?
