According to the governance of the energy union and climate action rules, which entered into force on 24 December 2018, EU countries are required to:

• develop integrated national energy and climate plans (NECPs) that cover the five dimensions of the energy union for the period 2021 to 2030 (and every subsequent ten year period) based on a common template;
• submit a draft NECP by 31 December 2018 and be ready to submit the final plans by 31 December 2019 to the European Commission;
• report on the progress they make in implementing their NECPs, mostly on a biennial basis.

The Commission will monitor the progress of the EU as a whole, notably as part of the annual state of the energy union report. If an individual country's draft NECP and its objectives, policies and measures do not sufficiently or not consistently contribute to reaching the energy union's objectives, or if the EU collectively does not make sufficient progress towards these objectives, the Commission may issue recommendations to countries by 30 June 2019 to amend the draft NECP. Member States then have until the end of 2019 to submit their final NECP.   

The Draft National Energy and Climate Plans (NECPs) submitted to the European Commission (as of 25 February 2019) are now avaialbe.
