Sponge - Battery Commissioning Fee

Product Description

• Reduce energy bills by up to 30% on top of your existing solar and battery savings.
• Cut the payback period on your Solar + BESS project by up to 4 years.
• Eliminate the trade-off between economic battery dispatch and backup power.

Sponge’s Net Metering Battery Optimization unlocks advanced value for systems operating under net metering by turning your battery into a precision tool for both savings and resilience. Designed for commercial and residential clients, this solution ensures your battery is always charged with the cheapest energy and discharged at the most profitable moment—while staying ready for outages.

Smart Forecasting, Smarter Control

Sponge uses advanced forecasting for solar production, building energy usage, and local outage risk to make intelligent, moment-to-moment decisions about how your battery is charged and discharged.

• On low-price nights, the battery charges from the grid.
  
• On sunny days, the battery stores free solar energy.
  
• At peak pricing hours, the battery discharges to avoid high utility rates.
  
• During grid instability or storm risk, Sponge ensures your battery is fully charged and ready to deliver backup power.
  
  

All this happens automatically, within the limits of your interconnection agreement.

Whether your goal is to reduce energy costs, enhance resiliency, or both, Sponge balances all factors in real-time to deliver maximum value.

Optimized for Net-Metered Systems

For PV + battery systems on net metering, Sponge ensures batteries are charged during low-cost periods and discharged when rates spike. This strategic dispatch maximizes self-consumption and reduces reliance on grid energy during expensive time windows.

You save more, faster—with less manual oversight.

Outage-Aware Dispatch

Unlike traditional economic dispatch systems, Sponge doesn’t leave you exposed during blackouts. In times of increased outage risk, it prioritizes battery state-of-charge for backup. When the risk passes, it resumes optimizing for financial performance.

Your system is always ready—for savings or storms.
