Obstacles in BESS Communication: Weather Extremes, Immediate Responses, and Cybersecurity Concerns

One of the most discussed technologies in the energy sector currently is large battery energy storage systems (BESSs). This innovation is not solely about storing energy—it stabilizes the balance between renewable energy sources, power networks, and consumer requirements. Hence, a dependable communication system is crucial for these three elements to harmonize effectively.

The obstacle of severe weather conditions

Extreme climatic events are occurring more frequently today compared to the past, as highlighted by the Intergovernmental Panel on Climate Change (IPCC). Heatwaves, in particular, are now 2.8 times more probable than in previous years. These conditions not only strain human life and farming but also impact electronic communication devices. Sharp temperature shifts, sandstorms, and lightning strikes can lead to malfunctions in communication equipment, consequently affecting BESS operations. Given that these storage systems are often located in remote areas, opting for highly robust, industrial-grade communication gear that can endure harsh environments is essential.

The need for instantaneous responses

As power grids advance and necessitate stricter management protocols, the swift charging and discharging abilities of large battery energy storage units are vital for grid stabilization. For instance, in the UK’s national grid, the demand for power auxiliary reaction time has reduced from an initial 10 seconds to only 500 milliseconds[1]. Some nations even aim for response times at the 100-millisecond level using the latest storage batteries. This suggests that upcoming communication systems must offer faster data transfer speeds, increased network bandwidth, and more dependable network redundancy schemes to meet these requirements.

Recent network security issues pose significant worries

Cyber threats targeting energy and power systems are rising, prompting increased focus on data security. Several nations now classify the power grid system as critical infrastructure at a national level, leading to more stringent cybersecurity requirements. Examples include NERC’s “Security Integration Strategy” and the EU’s “Network and Information Security Directive 2.0”. Hence, forthcoming BESS communication designs need to bolster cybersecurity defenses against the escalating online risks.

In conclusion, despite advancements in energy transition, BESSs confront mounting obstacles. Amidst this intricate journey, a stable communication network is indispensable. It must tackle climate challenges, fulfill stringent power auxiliary system demands, and fortify cybersecurity. Past experiences underscore the importance of considering various factors when selecting and designing communication systems to ensure stable operations. Going forward, BESS providers must vigilantly monitor these critical areas, persistently enhancing the performance and reliability of their communication infrastructure. To achieve sustainable energy solutions, large battery storage systems necessitate effective design and deployment.
