Cost-Benefit Analysis for availability of FCR Providers with Limited Storage capacity

The frequency primary reserve (FCR) in a synchronous area is of utmost importance for the operational reliability of the area since it allows the stabilization of the system frequency in the timeframe of seconds at an acceptable stationary value in case of a disturbance or an incident .

The project scope is to develop and implement a Cost-Benefit Analysis methodology to be applied by the TSOs in the Grid Codes of Continental Europe and Nordic synchronous areas, in order to assess the time period required for FCR providing units or groups with limited energy reservoirs to remain available during alert state as required in the Article 156(11) of the System Operation Guidelines adopted by European Commission in August 2017, which is the European regulation composed of the former network codes on Operational Planning and Scheduling (NC OPS), Operational Security (NC OS), and Load Frequency Control and Reserve (NC LFCR).

The developed Cost-Benefit Analysis is compliant with the official methodology proposed by the TSOs (“All Continental Europe and Nordic TSOs’ proposal for assumptions and a Cost Benefit Analysis methodology in accordance with Article 156(11) of the Commission Regulation (EU) 2017/1485 of 2 August 2017 establishing a guideline on electricity transmission system operation”).
