US onshore wind installations in the first quarter tumbled to 1.47GW, less than one-third of the new capacity added a year earlier, as the sector continues to struggle with a host of challenges including macroeconomics, project interconnection, and supply chain shortfalls, according to new data from the Federal Energy Regulatory Commission (FERC).

Eight wind farms came online versus 20 a year earlier, and only two in March totaling 409MW.
