Are solar project delays more common than cancellations?
Delays in solar project schedules tend to be relatively short in duration, and reports of delays are more common than cancellations: less than 1% of planned solar capacity is entirely cancelled in a typical month.
Are distributed solar photovoltaic prices still high?
Distributed solar photovoltaic prices have plummeted over the past decade, but nonequipment “soft costs” such as permitting, inspection, and interconnection remain stubbornly high.
Are interconnection wait times on the rise?
Another concerning trend is that interconnection wait times are on the rise. Interconnection requests now typically take more than 3 years to complete the requisite grid impact studies in most regions, though some – like ERCOT in Texas – are processing requests more quickly.
Is grid interconnection causing project delays & cancellations?
The Federal Energy Regulatory Commission (FERC) adopted major interconnection reforms in 2023 that have not yet taken effect in most regions; project developers continue to cite grid interconnection as a leading cause of project delays and cancellations.
