Key Financial Benefits of Energy Storage for Businesses
1. Cost Savings through Energy Arbitrage
Businesses can store energy when prices are low (off-peak hours) and use it during peak demand periods when electricity rates are higher. This time-shifting of energy consumption reduces electricity costs by avoiding high peak rates and taking advantage of time-of-use pricing plans provided by utilities.
2. Demand Charge Mitigation
A significant portion of commercial electricity bills can come from demand charges, which are fees based on the highest power usage during a short interval (e.g., 15 minutes or 1 hour) within a billing cycle. Energy storage systems help reduce these peak demands by supplying stored energy during peak times, thus lowering demand charges substantially. Since demand charges can be quite high (e.g., $15 per kilowatt or more), reducing peak demand with batteries leads to large savings.
3. Incentives, Tax Credits, and Rebates
Many regions offer financial incentives such as federal or state tax credits (like the Investment Tax Credit (ITC) that covers up to 30% of battery system costs), grants, or rebates to encourage businesses to install energy storage. These incentives improve the return on investment by lowering upfront costs.
4. Revenue Streams from Grid Services
Businesses can participate in grid programs by providing services like frequency regulation or spinning reserves through their energy storage systems. These ancillary services can generate additional revenue or cost savings, helping offset the costs of energy supply.
5. Increased Resilience and Avoided Outage Costs
By having a reliable backup power source, energy storage systems protect businesses against costly power outages that lead to lost productivity and revenue. This resilience translates into financial benefits by avoiding downtime and associated costs during grid interruptions or severe weather events.
Summary
Energy storage allows businesses to lower their electricity bills by reducing peak demand charges and leveraging time-based pricing, access various government incentives to reduce installation costs, and improve operational reliability which helps avoid costly disruptions. Additionally, participation in grid services can provide new revenue opportunities, making energy storage a financially beneficial investment for businesses.
These benefits combined typically result in a strong return on investment for commercial energy storage systems.
