Transmission Projects

Overview

Demand for power continues to grow throughout the region served by Southern California Edison (SCE). To keep pace and ensure future service reliability, SCE has undertaken a major infrastructure expansion and replacement project. The company has proposed investing approximately $20 billion during coming years to expand and renew the region’s essential distribution and transmission grids, making the power grid greener and smarter for 13 million Southern Californians.
