Green light for green power

UK Power Networks is to trial a revolutionary way of managing spare electricity network capacity that could save customers £271 million by 2030 and cut more than 448,000 tonnes of carbon emissions by 2030.

The company has been given the go-ahead for the research project that will potentially release spare capacity to support the predicted increase in electric vehicles. Ofgem approved the joint bid by UK Power Networks and SP Energy Networks as part of their annual Network Innovation Competition.
The project called Active Response will trial a responsive, automated electricity network that reconfigures itself constantly, moving spare capacity to where the demand is. It does this by using power electronics to move electricity from heavily loaded substations to nearby substations with spare capacity.
By 2030 it is anticipated there will be up to 1.9m electric vehicles in use across London, the East and South East of England where UK Power Networks delivers electricity – including London’s buses and taxis. This could significantly increase peak demand for electricity.
Under the regulatory system, the cost of building the additional capacity would have to be borne by customers, so UK Power Networks is using innovation to optimise its existing infrastructure to reduce this cost.
Active Response will be the first time that electricity networks can proactively move spare capacity around the system to support areas that are using more electricity. This means providing additional capacity in residential areas in evenings and at weekends when people are charging their cars, and then moving that spare capacity to where it is needed during the day – such as city centres, commercial hubs or electric fleet charge points.
Upgrading an electricity substation, or adding entirely new substations and cabling when customers need more power, takes time, costs money, and can cause roadworks. Instead, Active Response could allow electricity companies across the UK to use these power sharing techniques to connect new customers, and those requesting more power, quicker and at lower cost. 
Active Response could save customers nationwide £271million by 2030 and cut more than 448,000 tonnes of carbon emissions by 2030, which is the same as almost half a million return flights between London and New York.
Active Response builds on previous research projects such as Flexible Urban Networks – Low Voltage, which delivered pioneering results by proving that an entirely new use for power electronics could be deployed on the electricity network.
UK Power Networks is working with partners on the project including Turbo Power Systems, Ricardo and CGI.
