NEWS: Last month, SPP lost a 28-GW chunk of its interconnection queue.

Peace out: 122 projects left the grid operator’s queue in May—that’s nearly half of SPP’s biggest-ever interconnection cluster (mostly consisting of renewable and battery projects). What scared them off? Most likely the Phase 1 interconnection cost estimates, as noted by Interconnection.fyi. 

Sticker shock: Many of these projects faced “massive upgrade costs” to help fund new 765-kV transmission lines—SPP assigned the now-withdrawn projects a median cost of $655/kW.
