Fast Facts
Battery energy storage is one of the most talked-about - and one of the most frequently subject to misinformation - technologies being built across the country right now.
Communities are asking hard questions, and they deserve straight answers.
Here's what independent experts, fire safety authorities, and government scientists actually found.

The nation's top fire safety authority writes the rules for battery storage — and they're strict.

The same organization that sets the fire codes for your home and your kids' school, the National Fire Protection Association, has developed comprehensive standards specifically for battery storage facilities. Every modern system is required to have controlled spacing, explosion prevention, and advanced monitoring. This isn't unregulated technology being dropped in a community. It's one of the most heavily scrutinized forms of infrastructure being built today.
A New York state review found no harmful impacts to air, water, or public health
In 2023, New York organized a state-led working group, including environmental, health, and fire safety agencies, to review air, soil, and water data related to battery storage incidents. They found no injuries, no harmful levels of toxins, and no long-term impacts to surrounding communities. The findings are based on air, soil, and water data collected and analyzed by state agencies and their partners.
Air and water testing found no harmful impacts after battery fire

Following a 2024 battery fire in California, air and water quality were closely monitored by local HAZMAT teams and independent environmental labs. Air monitoring across nearby areas detected only typical byproducts of a structure fire, all well below established safety thresholds. Separate testing of runoff water found no harmful levels of metals and no evidence of environmental contamination, with results within accepted public health standards.

Independent researchers reviewed battery fire incidents across the country. Here's what they found.

An independent analysis reviewed battery storage fire incidents across the country and found no cases where air contamination reached levels that posed a public health risk. The report also found no evidence of long-term off-site environmental impacts requiring cleanup. Further, the report notes that many older incidents happened with early-generation technology that doesn't reflect what gets built today.

Washington’s energy demand is growing faster than supply. Battery storage may be the answer.
Source: E3 Study, commissioned by Northwest utilities
A major independent analysis found that the Pacific Northwest is likely to face a growing gap between energy supply and demand – starting as soon as 2026. That gap gets dangerous during heat waves and cold snaps, when demand spikes and the grid is already strained. Battery storage was identified as one of the fastest, most effective tools to keep power available when people need it most. The question isn't whether we need it. It's where we build it.
As Washington’s energy mix changes, reliability still matters.

Washington's shift to clean energy is something most Washingtonians support. But it creates a real challenge: solar and wind don't always show up when demand is highest. A Seattle Times editorial highlights that battery storage is already a proven tool that helps ensure the grid remains reliable and affordable as the energy mix evolves. This isn't about any single project. It's about how we build a more dependable energy system for the future.
Peak demand drives how much infrastructure we have to build.

Research from the U.S. Department of Energy’s Pacific Northwest National Laboratory found that peak electricity demand in 2024 was 56% higher than average demand, meaning the grid must be built to meet those highest-use moments. The report explains that energy storage can help shift electricity from times of lower demand to periods when demand is highest, improving how the system is used over time.
Every energy choice comes with tradeoffs

In an article in Fire Engineering, retired Seattle Fire Captain Chris Green argues that conversations about battery storage should also consider the alternatives. As electricity demand grows and states transition to cleaner energy sources, utilities still need reliable ways to store and deliver power when demand is high. Green notes that saying “no” to battery storage does not eliminate the need for energy infrastructure—it simply shifts the conversation to other technologies and tradeoffs. The article encourages communities to consider the broader reliability challenge facing the electric grid as Washington plans for future energy needs.

Extreme weather and grid strain are already affecting Washington communities.
Source: various
Recent events across Washington have shown how quickly the electric system can come under strain. Severe storms have left tens of thousands without power for days, while extreme cold has forced utilities to ask residents to conserve energy during periods of high demand. Research from the University of Washington also found that the state’s 2021 heat wave contributed to 159 excess deaths over a three-week period, underscoring the importance of reliable electricity during extreme weather events.

Battery storage is helping other states confront extreme weather and grid challenges head on. Washington should pay attention.
Source: Texas Tribune | Bloomberg
Extreme weather is putting growing pressure on electric grids across the country, especially during periods of high energy demand. During Winter Storm Fern in early 2026, battery storage systems supplied thousands of megawatts of electricity during critical hours of grid stress, helping support reliability as demand surged. According to reporting from the Texas Tribune, battery storage provided enough electricity at one point to power the equivalent of roughly 1.75 million homes. Bloomberg described the storm as one of the first large-scale real-world tests of modern battery storage systems during a major winter weather event. As Washington plans for rising electricity demand and more frequent extreme weather events, experiences like these offer a real-world example of how battery storage can help support a more reliable and resilient grid.

Battery storage is putting American workers to work – including union trades.

The energy storage industry has attracted more than $100 billion in U.S. investment and supports an estimated 350,000 jobs in manufacturing and supply chains across the country. Projects like this one are part of a national push to build our energy infrastructure here at home, with American workers. Clean energy isn't just an environmental story. It's a jobs story.
