Siemens Energy announced that it will provide four static synchronous compensator (STATCOM) installations for LS Power Grid California, LLC (LS Power) substation projects in California. A STATCOM is a quick-reacting system capable of providing or absorbing reactive power to regulate the voltage at the point of connection to a power grid. This voltage regulation will be key to ensuring the reliability of the power grid as renewable energy sources are brought online, enabling further decarbonization of Californias energy mix. With the retirement of Pacific Gas and Electric Co.s (PG&E) Diablo Canyon nuclear power plant in 2025, it is expected that there will be greater sensitivity to voltage instability, especially as PG&E integrates more renewable generation onto the grid. Two of the STATCOM systems are to be installed at LS Powers Orchard substation connecting to the existing PG&E Gates 500 kilovolt (kV) substation in Fresno County to provide 848 megavolt-ampere (MVAr) of dynamic reactive power support. Under the light-load conditions, this support is anticipated to mitigate high voltages during extreme contingencies on the Bulk Power System. The other two STATCOMs will be installed at LS Powers new Fern Road substation connecting the Round Mountain to Table Mountain 500 kV transmission lines. The purpose of these systems will be for voltage control and voltage support in case of system events and transmission outages.
