Managing the electricity grid 24/7/365 without any ‘outage incidents’ is no mean feat, and while the numbers of power cuts have decreased, the role of preventing them is changing as our energy structures evolve. The UK and Scottish governments have both committed to meet tough ‘net zero’ emission targets, and changing the way we generate power is an essential part of meeting those targets. This change has been most drastic in Scotland where in recent years we have shut down our last two coal-burning power stations at Longannet and Cockenzie and have switched instead to impressive levels of renewable generation. Moving to greener energy is good, right? Well yes, definitely. It’s not just essential for our environment, it also provides significant benefits to consumers and in many ways makes our electricity grid more secure. However it does also bring with it new challenges, and policy-makers need to take these into account too. National Grid, which manages Britain’s electricity transmission grid, has stated that wind variability was not responsible for the recent power cut that affected swathes of England for up to 90 minutes. While this is true, they won’t deny that their role is becoming ever more complex as more and more separate generators connect to the grid. What the power cut did expose was how people’s everyday lives are becoming more and more reliant on electricity. So while last month’s power cut has been classed as an extremely rare event, the likes of which hadn’t been seen since 2008, the public reaction has shown how a loss of power at such a scale is unacceptable to today’s society. In the 1970s we grumbled, lit our candles and made our own entertainment. Those days have gone and now people want answers.
