Germany's TSOs begin inertia procurement
Germany has initiated a new procurement process for inertia services to support its renewable energy grid. This follows a determination by the Federal Network Agency and the launch of the country's first large-scale grid-forming battery energy storage system. The procurement offers both premium and basic products with varying availability requirements and prices.
- ▪Germany's Federal Network Agency has launched a procurement process for inertia services.
- ▪The new procurement includes both positive and negative products with different availability requirements.
- ▪Prices for the inertia products range from €76/MWs to €888.5/MWs depending on the product type.
Opening excerpt (first ~120 words) tap to expand
As has been extensively covered by Energy-Storage.news, while wind and solar PV can replace thermal generation on the grid with the help of energy storage and other flexibility and capacity resources, variable renewable energy (VRE) still leaves a gap in the provision of system stability services that grid-forming assets can deliver instead. While other ancillary services, most prominently frequency regulation or frequency response, deliver power to the grid or absorb it to offer correction when supply and demand imbalances occur, inertia is therefore more about maintaining frequency.
