Pattern Development, sister company to US wind yieldco Pattern Energy, announced that regulators in New Mexico have issued a key permit that will allow it to begin construction on its 2.2GW Corona portfolio of wind projects in the southwestern state.

New Mexico’s Public Regulation Commission voted 4-0 to approve the local control permit for the Corona portfolio, which will see around 950 wind turbines installed by the end of 2020, Pattern Development says.
