Invenergy and New Mexico Renewable Energy Transmission Authority (RETA), an independent state authority, are entering into agreement to jointly develop a $2bn power line capable of moving 4GW of solar and wind energy within the US desert Southwest.

The future public-private partnership’s proposed 644km (400-mile) high-voltage direct current (HVDC) conduit called North Path will help to unlock a share of what RETA has estimated is $11bn in untapped renewable energy investment potential in the state.
