Energy storage is a critical part of U.S. infrastructure—

keeping the grid reliable, lowering energy costs, minimizing power outages, increasing U.S. energy production, and strengthening national security.

The U.S. storage sector is experiencing remarkable growth. That's because energy storage is the only technology connected to the grid that can capture excess energy when it would otherwise be wasted, and re-deliver that energy to the grid when it's most needed.

‍

Energy storage is truly unique in its ability to add flexibility and efficiency to our nation's power grid.

Battery energy storage systems (BESS) are great neighbors. Storage's unique capabilities serve communities in safe, clean, efficient, and affordable ways. Storage provides reliability during historic adverse weather events, serving as back-up power for individual homes, businesses, communities, and the broader grid system to minimize and prevent costly and dangerous power outages.

‍

Battery storage is designed with safety as an inherent feature. The storage industry also coordinates with governments and regulators to ensure projects are built to account for the safety needs of every community.

What is Energy Storage?

1 // 5

Energy Storage Saves Money & Reduces Costs

By storing energy when the price of electricity is low and discharging that energy later during periods of high demand, energy storage can reduce costs for utilities and save families and businesses money.

Also, by enhancing grid reliability and providing back-up power, energy storage can prevent costly damages to families and businesses associated with power outages.

Energy Storage Encourages More US-Produced Clean Energy

Wind and solar are the cheapest sources of electricity—electricity that is produced in America. Energy storage supports using more clean energy by storing it when supply is high but demand is low, which enables the grid to incorporate more of the most cost-effective sources of electricity generation.

Energy Storage is Safe

Grid-scale battery energy storage is safe and highly regulated, growing safer as technology advances and as regulations adopt the most up-to-date safety standards.

Fire incidents at energy storage facilities are extremely rare occurrences and remain isolated, but the industry has taken a proactive approach to working with policymakers and fire officials to promote safety. And as more facilities are built, the percentage of battery fires continues to decrease.

Energy Storage Supports Local Economies

The rapidly-growing industry supports 72,000 good-paying jobs through development, construction, and maintenance of storage facilities.

A recent U.S. manufacturing renaissance added to the 10,000 new jobs at factories producing storage technology across the country.

Energy Storage Reduces Power Outages

Energy storage technologies have the unique capabilities to keep the lights on when the power grid is under stress. In both Texas and California, energy storage technologies have prevented black outs during significant heatwaves—keeping people safe, power affordable, and the power on for businesses.

Energy Storage is Energy Efficient

By storing energy when there is excess supply of clean energy compared to demand, energy storage can reduce the need to stop (curtail) generation facilities and instead store and use the excess energy later when it is needed.

Storage is also instantly dispatchable, so it helps the grid adjust to fluctuations in demand and supply, which increases grid flexibility, alleviates transmission congestion, and optimizes grid efficiency—reducing overall system costs.

3,000 megawatts of new energy storage resources—in states like Maryland—can result in $100 million per year saved in electricity costs

How New Battery Capacity Helped California Avoid Another Blackout

“The August 2020 heatwave resulted in a surge in demand to a peak of 46.8 GW, which resulted in blackouts. Even though the September 2022 heatwave caused a higher demand of 51.4 GW, new BES[S] provided 3.4 GW of peak generation to help prevent the blackouts.”
