resources in providing decentralised resilience. Some pioneering organisations are now turning to smart battery energy storage systems (BESS) and onsite power sources capable of providing off-grid power during an outage. Intelligent power management systems can now perform ‘planned islanding’, intentionally disconnecting from affected electricity networks and then conduct a ‘blackstart’, restoring full power from onsite battery storage and power sources within 30 seconds. These systems can even form microgrids able to operate fully independently from the main grid.
Advanced energy management systems can intelligently regulate energy consumption, production and storage across buildings to balance off-grid supply and demand during an outage. For example, they can reduce the output of onsite power sources such as solar panels or diesel generator sets, to avoid overcharging batteries or reduce unnecessary power consumption to conserve electricity. Power management systems can also seamlessly switch between power sources, such as drawing from diesel generator sets when solar production is lower. Advanced data analytics can automatically synchronise voltage and frequency levels with those of the main grid, enabling buildings to seamlessly reconnect to the grid without disruption when the power comes back.

This not only improves energy security but also plugs gaps in supply. One Southern European customer combined our smart Power Management System and BESS with solar PVs to provide off-grid power for EV chargers, accelerating the rollout of ultra-fast chargers across areas that lacked suitable network connections. This demonstrates how smart onsite energy storage and management can both improve resilience and accelerate the renewable energy transition across sectors such as transport.
Beyond resilience Beyond resilience, there are also many revenue streams for islanding systems such as tapping into price schemes rewarding major consumers for reducing peak-time consumption. Surplus power can also be sold to provide flexibility and frequency response services for the grid. Some organisations are even developing ‘resilience-as-a-service’ offerings for smaller commercial and industrial facilities.
Ultimately, we must move from a system where power grid resilience is a single point of failure towards a multi- layered model of resilience including distributed energy management, storage and generation.
