Demand Charge Management
Solar reduced 25% of the site’s maximum demand. The addition of the Acumen EMS™-enabled storage system shaved an additional 24%.
Over the first year of operation, the combined system captured 71% of the maximum demand savings possible.
The percentage of monthly peak demand reduced from PV and ESS generally improved throughout the first year of operation, as the Acumen EMS™ machine
learning model improved its site load and PV production forecasting ability.
