By 6 months after entry into force of this regulation, the TSOs of the CE and Nordic synchronous areas shall propose assumptions and methodology for a cost-benefit analysis to be conducted, in order to assess the time period required for FCR providing units or groups with limited energy reservoirs to remain available during alert state. By 12 months after approval of the assumptions and methodology by all regulatory authorities of the concerned region, the TSOs of the CE and Nordic synchronous areas shall submit the results of their cost-benefit analysis to the concerned regulatory authorities, suggesting a time period which shall not be greater than 30 or smaller than 15 minutes. The cost-benefit analysis shall take into account at least: experiences gathered with different timeframes and shares of emerging technologies in different LFC blocks; the impact of a defined time period on the total cost of FCR reserves in the synchronous area; the impact of a defined time period on system stability risks, in particular through prolonged or repeated frequency events; the impact on system stability risks and total cost of FCR in case of increasing total volume of FCR; the impact of technological developments on costs of availability periods for FCR from its FCR providing units or groups with limited energy reservoirs.
