Quantum computers will break the encryption protecting your energy infrastructure.
The countdown to "harvest now, decrypt later" has already started.
Post-quantum cryptography is not a future consideration for BESS operators. It is an active threat vector today, because adversaries are already harvesting encrypted communications from grid-connected infrastructure with the intention of decrypting them once sufficiently powerful quantum computers become available. NIST finalised its post-quantum cryptographic standards in 2024, and EU mandates for critical infrastructure operators are now following. 247 Energy's March 2026 whitepaper on quantum technology and energy infrastructure is the first publication in the European storage sector to provide a four-step post-quantum transition framework specifically designed for BESS operators and infrastructure investors.
