Utility-scale batteries play a crucial role in reducing electricity costs by storing energy when prices are low and discharging it during periods of high demand and high prices. This load shifting helps utilities, businesses, and consumers save significantly on energy costs. For example, in Texas, energy storage deployments alone saved consumers $750 million in energy costs during the summer of 2024.
These batteries improve grid flexibility and reliability by balancing supply and demand continuously. They allow electricity generated during off-peak hours or from renewable sources like solar to be stored and used later when electricity demand and prices spike, thereby mitigating the need for expensive peaking power plants and reducing exposure to volatile wholesale electricity prices.
Moreover, pairing battery storage with renewable energy enhances the use of affordable clean energy by storing excess solar power produced during the day for use at night or during cloudy periods. This reduces reliance on fossil fuels and foreign imports, which often come with higher and more unstable costs.
From a cost perspective, utility-scale battery storage system capital costs are declining over time, with projections showing continued, though slowing, cost reductions through 2050, improving the economic case for deployment and further electricity cost savings.
In summary, utility-scale batteries reduce electricity costs by:
- Storing low-cost energy and discharging it at high-cost times to avoid expensive peak power generation.
- Enhancing the integration and utilization of cost-effective renewable energy.
- Increasing grid reliability, reducing outage risks, and smoothing fuel cost volatility.
- Contributing to long-term cost declines in energy storage systems themselves.
These factors combine to lower the overall cost of electricity for consumers and utilities while supporting a cleaner, more resilient electric grid.
