July 26, 2012. San Diego Gas & Electric (SDG&E) and local officials gathered to officially inaugurate the Sunrise Powerlink transmission line. The dedication ceremony was held at SDG&E's new Suncrest Substation, an electric facility that is a key component of the Sunrise Powerlink. The 117-mile, 500-kV Sunrise Powerlink will carry clean energy from developing solar and wind farms in California's Imperial Valley to San Diego and enable SDG&E to increase the amount of renewable power it delivers to 33 percent by 2020, a key California environmental initiative.
