# Southern California Edison Energizes 500 kV Substation for 1200 MW Mojave Clean Energy Hub > Southern California Edison (SCE) has energized a new 500/230 kV bulk substation featuring 3 transformer banks rated at 600 MVA each to interconnect 1200 MW of solar and battery storage in Kern County. - **Source date:** 2026-10-03 - **Original source:** [Southern California Edison Newsroom](https://newsroom.edison.com/releases/mojave-500kv-transmission-substation-october-2026) - **Reading time:** 1 min - **Language:** en - **URL:** https://voltformer.com/news/sce-energizes-500kv-mojave-transmission-substation-october-2026 - **Markdown:** https://voltformer.com/news/sce-energizes-500kv-mojave-transmission-substation-october-2026.md ## High-Capacity Renewable Transmission Node The new 500 kV substation ties into the major bulk transmission network and provides interconnection bays for 3 utility-scale solar and BESS developers. 3 autotransformers rated at 600 MVA each facilitate the transfer of 1200 MW of clean generation into the CAISO wholesale electricity market. ## Grid Voltage Stability and Power Quality The substation includes a 250 Mvar static synchronous compensator to maintain transmission voltage stability during rapid solar generation changes. Integrated digital relays and synchrophasor PMUs provide real-time dynamic visibility with 60 samples per second streaming to grid controllers. ## Other languages - [en](https://voltformer.com/news/sce-energizes-500kv-mojave-transmission-substation-october-2026) - [tr](https://voltformer.com/tr/news/sce-energizes-500kv-mojave-transmission-substation-october-2026) - [de](https://voltformer.com/de/news/sce-energizes-500kv-mojave-transmission-substation-october-2026) - [ru](https://voltformer.com/ru/news/sce-energizes-500kv-mojave-transmission-substation-october-2026) - [es](https://voltformer.com/es/news/sce-energizes-500kv-mojave-transmission-substation-october-2026) - [ar](https://voltformer.com/ar/news/sce-energizes-500kv-mojave-transmission-substation-october-2026) - [it](https://voltformer.com/it/news/sce-energizes-500kv-mojave-transmission-substation-october-2026) - [pt](https://voltformer.com/pt/news/sce-energizes-500kv-mojave-transmission-substation-october-2026) [Company and energy news](https://voltformer.com/news.md) ยท [Voltformer catalog](https://voltformer.com/catalog)
