Battery Storage Called Into Action As UK Suffers Country-Wide Power Cuts

Battery storage assets were called into action last week after the UK suffered country-wide power outages following a transmission system stress event. On August 9th, two large generators were disconnected from the UK’s power system almost simultaneously, effectively taking 2GW worth of electricity generation within minutes of each other. That collapse in generation sent the country’s transmission grid frequency to dip, so National Grid, the country’s electricity system operator, called on reserve and flexible generation capacity to respond, with many operators dispatching battery storage capacity to meet National Grid ESO’s calls.
