• Voltage and reactive-power support where technically applicable
• Reserve and flexibility services through aggregators or market access partners
• Revenue stacking with energy arbitrage and other operating modes

EMS and dispatch

Successful participation requires more than battery hardware. The EMS must coordinate state of charge, availability, dispatch signals and other operating constraints while protecting the asset.
