Overview

In response to the state’s growing energy needs, Southern California Edison’s 1,054 megawatt Mountainview Generating Facility power plant in Redlands needed an upgrade.

The challenge

Due to the region’s increasing presence of renewable energy, the site needed more flexibility to respond faster to California’s ISO system demands. The state’s share of electricity from renewables has more than doubled from <25% renewables in 2008 to ~50% today.*

The solution

The Southern California Edison-owned plant collaborated with GE to develop a package solution that will reduce its start-up times, and lower emissions without using additional water. The combination of Advanced Gas Path (AGP), Dry Low NOx 2.6+ (DLN2.6+) combustion and OpFlex** software upgrades positioned Mountainview to help balance the region’s grid demands.

SCE will benefit from a boost in its station’s output by about 48 megawatts (MW), an increase in efficiency and longer intervals between maintenance outages. By expanding Mountainview’s flexibility, the project will help SCE protect the grid from volatility, while also strengthening its competitive position in California.
