Why has SDG&E proposed this project instead of just upgrading existing transmission lines?
A. SDG&E is doing both. Expanding the transmission system is part of SDG&E’s balanced, long-term resource strategy to ensure reliability, which first calls for improved energy efficiency and conservation, then increased use of renewable energy, construction of new power plants and expansion of the transmission system. SDG&E has recently made significant upgrades to its local transmission system, including the addition of the 230-kV Mission-Miguel #2 transmission line and expansion of the Miguel substation. But San Diego still has only two major transmission links to the statewide grid. Adding a new line provides the greatest flexibility to meet future growth and to integrate with the transmission system across the western U.S. Also, just upgrading existing lines would not offer the same access to renewable energy resources.
