Inaccess successfully completed the commissioning of the EMS and SCADA in a 75MW / 300 MWh energy storage project located in Kings County, California, USA. The 4-hour storage project, which is based on lithium iron phosphate (LFP) battery technology, is a retrofit addition to an existing 100MWAC / 134MWDC solar plant.

With the addition of batteries, the energy generated from the sun during the day can be stored for use in the evening when the demand is higher. This approach allows California’s power grid to absorb and integrate higher levels of reliable, safe and affordable renewable energy.

Our EMS efficiently control the Power Conversion Systems (PCSs) and the Battery Containers to provide a wide range of functionality including (but not limited to) active/reactive power control, State of Charge (SoC) management and balancing, ramp rate control and energy time shifting. Our system will support the operation and maintenance of the asset throughout its lifecycle with intelligent alarm management and battery specific reporting that includes several crucial KPIs for its performance guarantees ensuring system output, reliability, and safety. The system is also designed to be easily expandable to accommodate any future augmentation services.
