SDG&E Sunrise Powerlink Transmission Project EIR/EIS. Under contract to the CPUC, and under a Memo-randum of Understanding with BLM, Aspen is preparing an EIR/EIS for a highly controversial 150-mile trans-mission line from Imperial County to coastal San Diego County to deliver renewable and low-cost power. Aspen coordinated transmission planning and engineering alternatives as part of the environmental review and provided discussion of net greenhouse gas emissions for multiple generation and transmission scenarios. The 500 kV line would pass through Anza-Borrego Desert State Park, and a 230 kV line would continue through rural San Diego County with both overhead and underground segments.
