Study: Transmission feasible for southwestern renewable energy

Development of about 9,500 to 12,500 megawatts of transmission capacity is technically feasible according to the November 2010 Sonoran-Mojave Renewable Transmission Project,  or SMRT, Preliminary Feasibility Study, released Dec. 8.

The study looked at a number of potential new transmission lines and upgrades to existing lines that would, if constructed, provide new transmission capacity in Arizona, California and Nevada primarily to support additional renewable resources, provide wholesale and retail markets with access to those resources and provide a more robust transmission grid.

The study was jointly developed and funded by a diverse group of energy interests that voluntarily band together to determine the technical feasibility of the lines and explore potential business arrangements to develop SMRT. With the preliminary study complete, the next steps will include soliciting interest in transmission service from renewable developers and other customers to assess SMRT’s economic viability.
