The US government has opened the door to global offshore wind developers to submit expressions of interest for commercial leases in two new deepwater areas off the coast of central California, moving the country a step closer to launching construction of as much as 3GW of floating projects.

The two zones, identified as Morro Bay Call Area East and West Extensions, are spread over 364km2 (90,025 acres) within a larger tract called Morro Bay 399 Area in federal waters in the Pacific Ocean.
