P Energy Networks is re-energising its electricity network by using the latest technology to tap into renewable energy from wind turbines and hydro generation. SP held a trial in Galloway, Scotland, as part of the second phase of a world-leading project, to show how the range of smaller energy sources could be used to restore power in the unlikely event of a total or partial shutdown of the national electricity transmission system. The Distributed ReStart project – a partnership of SP Energy Networks, National Grid ESO and specialist energy consultancy TNEI, and funded by the regulator Ofgem – explores the use of distributed energy sources such as solar, wind or hydro, to kickstart the energy system.
