Technical approach

As reported
Wind farms

Large-scale wind generation

Pattern builds multi-GW wind farms in areas with consistent wind (New Mexico, Canada, Central America), using modern large-rotor turbines.

HVDC transmission

Long-distance high-voltage DC lines

SunZia uses HVDC to transmit power 550 miles with lower losses than AC; HVDC is essential for remote wind farms feeding distant load centers.

Markets

Wholesale power sales

Pattern sells power through power purchase agreements (PPAs) with utilities and large commercial customers, securing stable long-term revenue.

Integration

Grid services and storage

Wind farms are increasingly paired with battery storage to smooth variable output and provide grid services like frequency regulation.
