New Report Explores Potential of PQC to Protect Battery Energy Storage Systems (BESS)

The US electric grid is a vital national asset and mission-critical infrastructure, underpinning American security and economic stability. Enter battery energy storage systems (BESS), which are playing an increasingly important role in the grid, enhancing reliability, facilitating the integration of renewable energy resources, and optimizing grid operations. A BESS functions as a large-scale rechargeable battery that stores energy when it is abundant and releases it when demand peaks or renewable generation dips. This capability helps address the intermittency of renewable energy resources while supporting overall grid stability.

BESS are vulnerable to cyberthreats, however. What happens when cybercriminals exploit encryption flaws? Imagine a quantum-powered adversary intercepting internet traffic protected by outdated encryption, gaining unauthorized access to energy grid controls. Such an attack could compromise critical infrastructure, leading to widespread disruptions or even nationwide blackouts.

With these risks in mind, Pratero and TruGrid have released a joint white paper exploring the importance of securing battery energy storage systems (BESS) with post quantum encryption (PQC). The paper addresses the vulnerabilities of traditional encryption methods, along with implementation strategies for integrating PQC into U.S. energy infrastructure.
