Growing the Grid
Interconnection Opportunity
RioSol is leading the way in developing high-potential energy regions through opportunities for interconnections to enhance the delivery of power to regional electric utilities in New Mexico and Arizona.
Electrical Utilities
Designed for More Interconnection
The RioSol Transmission Project (RioSol) will be an approximately 550-mile, 500kV alternating current (HVAC) line with a proposed eastern terminus in central New Mexico (near Corona, NM), a proposed western terminus at or near the Pinal Central substation in central Arizona (near Coolidge, AZ) and potentially several intervening substations. Given that RioSol will be an HVAC line, it will be designed to have multiple points of interconnection with the existing EHV transmission system and thus enable deliveries of electrical energy to many of the regional electric utilities.
