As more homes, businesses, and cities start using clean energy like solar and wind, we also need ways to store that power. That’s where Battery Energy Storage Systems (BESS) come in. These big batteries help keep energy ready for when we need it. But there’s one big problem that’s not getting enough attention: cybersecurity.
These storage systems are now targets for hackers. Experts have found serious risks that could let cybercriminals mess with the systems, shut them down, or even cause damage. In 2024, researchers found over 40 security flaws in the software of solar and battery equipment used around the world. If hackers take advantage of those weaknesses, they could turn off power, damage equipment, or steal private information.
Some battery systems even come with software built outside the U.S., and it's hard to know how secure they really are. This is especially risky when these systems are connected to larger energy grids that serve entire communities.
A few real incidents have already raised red flags. For example, the Moss Landing battery plant in California had a fire linked to its storage systems. While that incident wasn’t confirmed to be a cyberattack, it shows what can go wrong when battery systems fail—whether by accident or by someone with bad intentions.
So, what can we do to stay safe?
Energy experts and companies that make battery systems are working on solutions. Some of the most important steps include:
- Protecting systems from the inside out: From design to installation, security needs to be part of every step.
- Keeping software up to date: Outdated programs are easy for hackers to target.
- Separating networks: Battery systems shouldn’t be connected to other networks like company Wi-Fi or unsecured internet.
- Monitoring systems 24/7: That way, any strange behavior can be caught and stopped quickly.
As we move toward a cleaner, more digital energy future, cybersecurity has to be part of the conversation. Battery storage is powerful and useful, but it must also be protected. Making sure these systems are safe means making sure our lights stay on, our homes stay powered, and our future stays secure.
