​ACER publishes today its opinion on ENTSO-E’s Winter Outlook Report 2015/16 and Summer Review 2015. The Agency welcomes ENTSO-E’s continuous improvements of adequacy outlooks but highlights the need for their further development. In the Agency’s Opinion the seasonal adequacy reports would especially benefit from improved assessments of the impact of RES generation on the stability of the system and from further developments of the probabilistic assessment of system adequacy.

The seasonal adequacy reports are published by ENTSO-E twice a year and include the adequacy outlook for the coming summer or winter season and the review of the previous season. The Winter Outlook 2015/16 reports on the outlook of the national and regional power balances of forecast generation and load on a weekly basis for the upcoming winter period, from 1 December 2015 to 3 April 2016. The Summer Review 2015 focuses on the main events of the period from 1 June 2015 to 20 September 2015, which were relevant for security of electricity supply according to TSOs.
