Wind power will require lifestyle change
Electricity consumers in the UK will need to get used to flicking the switch and finding the power unavailable, according to Steve Holliday, CEO of National Grid, the country’s grid operator. Because of a six-fold increase in wind generation, which won’t be available when the wind doesn’t blow, “The grid is going to be a very different system in 2020, 2030,” he told BBC’s Radio 4. “We keep thinking that we want it to be there and provide power when we need it. It’s going to be much smarter than that.
Holliday has for several years been predicting that blackouts could become a feature of power systems that replace reliable coal plants with wind turbines in order to meet greenhouse gas targets. Wind-based power systems are necessary to meet the government’s targets, he has explained, but they will require lifestyle changes.
Under the so-called “smart grid” that the UK is developing, the government-regulated utility will be able to decide when and where power should be delivered, to ensure that it meets the highest social purpose. Governments may, for example, decide that the needs of key industries take precedence over others, or that the needs of industry trump that of residential consumers. Governments would also be able to price power prohibitively if it is used for non-essential purposes.
Smart grids are being developed by utilities worldwide to allow the government to control electricity use in the home, down to the individual appliance. Smart grids would monitor the consumption of each appliance and be capable of turning them off if the power is needed elsewhere.
