Welsh Power is to provide National Grid ESO with inertia thanks to the installation of a synchronous condenser and flywheel at its site at Rassau, Wales. Having been awarded a contract to provide inertia earlier this year – with £328 million of contracts awarded to five companies including Drax and Statkraft – the company is now working with its project development and finance partner, Quinbrook Infrastructure Partners, to install the technology. Traditionally, inertia – which is vital to the stability of the grid – has come from the kinetic energy in the moving parts of large generators while they are providing electricity to the grid. However, all of the companies that won the stability contracts are either modifying existing assets or building new assets to provide stability services from inertia, without having to provide electricity.
