BATTERY ENERGY STORAGE SYSTEMS (BESS)
SOLON offers battery energy storage systems to help customers reduce utility bills even further than what can be achieved with solar alone. As utility rate structures change, more customers are looking to energy storage as an additional way to reduce utility costs.
There are multiple factors to consider when designing an optimal battery energy storage system and every project is unique. System sizing entails many things. We take into consideration annual power consumption, future power needs, utility demand charges, existing utility rate plans, desire for battery backup during grid outages, and more, and combine that with an energy storage analysis to determine if a customer will benefit from installing a battery energy storage system.
Unlike a normal battery, battery energy storage systems contain intelligent technology and provide a turnkey system that provides one or more of the following benefits:
Demand Reduction
- Energy storage helps manage utility costs by eliminating short-term spikes in usage, thereby reducing monthly peak demand charges.
- Battery would turn off during grid outage.
Energy Arbitrage
- Most utility rate plans include much higher rates during peak usage times. Energy storage allows customers to utilize stored energy during peak hours to reduce costs.
- Batteries then charge with solar energy or when electricity is the least expensive and discharge during most expensive times of use.
Battery Backup Only
- Energy storage allows customers to avoid disruptions during grid outages and helps ensure critical systems remain operational.
- Battery is charged by solar energy and/or by grid power.
- Battery would only be active during a power outage.
Microgrid
- Energy storage is combined with a solar energy system to power the facility during a grid outage.
Hybrid Demand Reduction and Battery Backup
- A portion of the stored energy is used for demand reduction, while ensuring a portion remains available to provide backup power during a grid outage.
