OIES Paper on Meeting the Challenge of Reliability on Today’s Electric Grids: The Critical Role of Inertia

Grid systems that move away from power plants with synchronous spinning turbines need a strategy for addressing the loss of inertia. Better situational awareness can help, as can incentives to encourage the retention and production of inertia. This OIES paper looks at British and Nordic experiences and responses, and outlines what to watch for - so that the coming century, like the last one, is marked by a central role for reliable electric supply.
