The SO Regulation provides the rules and standards to ensure the required level of operational security, frequency, quality and efficient use of the interconnected system and resources. The SO Regulation entered into force on 14 September 2017.
Find out more about the evolution of the SO Regulation.
The SO Regulation applies to significant grid users that are further characterised as (new or existing):
The network code provides a minimum degree of harmonisation and leaves certain details to further implementation procedures at regional level. This also applies to terms and conditions, as well as to methodologies, in connection to:
Terms and conditions and methodologies can be subject to the approval of:
The TSOs' proposal should be consulted upon and submitted to the relevant regulatory authorities for approval. The proposal should contain a timescale for implementation and expected impact on the Regulation's objectives.
The NRAs involved should take decisions within six months after receiving the proposal. In case of disagreement, the regulatory authorities can request an amendment, allowing TSOs two more months for adjustments and additional two months for the regulatory authorities to approve the revised proposal. If the NRAs do not reach a unanimous agreement, or if they jointly request so, ACER can adopt a decision within six months from the referral.
Once the terms and conditions or methodologies are adopted, they can be amended after the request of the relevant TSO or NRA. In this case, the proposals for adjustments should be submitted for consultation and undergo a new approval procedure.
The implementation table provides more details on the latest updates.
