On 4 November National Grid ESO published an invitation to tender for new inertia solutions that can be deployed as early as April 2020. In this tender (Phase One of its ‘pathfinder’) it is expects to pick from a limited pool of technologies but it promised to open the net to a wider range of technologies in Phase two.
Meanwhile, the electricity system operator has been working on two solutions for understanding and measuring system inertia in real-time. A better understanding of that should make the system more secure – and potentially cut costs, as with real data the ESO is less likely to over-procure to meet system needs.
