54 GWh of storage capacity by 2030
FERC order allowing storage resources to participate in the wholesale market is expected to buoy renewable-plus-storage investments
Batteries value is “stackable” o Emergency backup power / energy resiliency o Reduce demand charges o Provide system capacity o Add value to solar standalone projects
✓ We intend that most of Altus’ facilities will eventually include storage technologies because of declining costs
