TITLE 4

Each TSO shall make any forecast used for control area adequacy analyses pursuant to Articles 105 and 107 available to all other TSOs through the ENTSO for Electricity operational planning data environment. Each TSO shall perform control area adequacy analysis by assessing the possibility for the sum of generation within its control area and cross-border import capabilities to meet the total load within its control area under various operational scenarios, taking into account the required level of active power reserves set out in Articles 118 and 119. When performing a control area adequacy analysis pursuant to paragraph 1, each TSO shall: use the latest availability plans and the latest available data for: the capabilities of power generating modules provided pursuant to Article 43(5) and Articles 45 and 51; cross-zonal capacity; possible demand response provided pursuant to Articles 52 and 53; take into account the contributions of generation from renewable energy sources and load; assess the probability and expected duration of an absence of adequacy and the expected energy not supplied as a result of such absence. As soon as possible, following the assessment of an absence of adequacy within its control area, each TSO shall notify the absence to its regulatory authority or when explicitly foreseen in national law, another competent authority, and where applicable, any affected party. As soon as possible, following the assessment of an absence of adequacy within its control area, each TSO shall inform all TSOs through the ENTSO for Electricity operational planning data environment. Each TSO shall contribute to the pan-European annual summer and winter generation adequacy outlooks applying the methodology adopted by ENTSO for Electricity referred to in Article 8(3)(f) of Regulation (EC) No 714/2009. Twice a year, each TSO shall perform a control area adequacy analysis for the following summer and winter respectively, taking into account pan-European scenarios consistent with the pan-European annual summer and winter generation adequacy outlooks. Each TSO shall update its control area adequacy analyses if it detects any probable changes to the availability status of power generating modules, load estimations, renewable energy sources estimations or cross zonal capacities that could significantly affect the expected adequacy. Each TSO shall perform a control area adequacy analysis in a day-ahead and intraday time-frame on the basis of: schedules referred to in Article 111; forecasted load; forecasted generation from renewable energy sources; active power reserves in accordance with the data provided pursuant to Article 46(1)(a); control area import and export capacities consistent with cross-zonal capacities calculated where applicable in accordance with Article 14 of Regulation (EU) 2015/1222; capabilities of power generating modules in accordance with the data provided pursuant to Article 43(4) and Articles 45 and 51 and their availability statuses; and capabilities of demand facilities with demand response in accordance with the data provided pursuant to Articles 52 and 53 and their availability statuses. Each TSO shall evaluate: the minimum level of import and the maximum level of export compatible with its control area adequacy; the expected duration of a potential absence of adequacy; and the amount of energy not supplied in the absence of adequacy. Where, following the analysis in paragraph 1, adequacy is not fulfilled, each TSO shall notify the absence of adequacy to its regulatory authority or other competent authority. The TSO shall provide its regulatory authority or other competent authority with an analysis of the causes of the absence of adequacy and propose mitigating actions.
