NOA methodology

The NOA is our recommendation for which reinforcement projects should receive investment during the coming year to facilitate the development of an efficient, coordinated, and economical system of electricity transmission. This must be consistent with the National Electricity Transmission System Security and Quality of Supply Standard (NETS SQSS), as well as the development of efficient interconnection capacity.

The NOA methodology describes how we assess the required levels of network transfer, the options available to meet this requirement and recommends options for further development. The methodology also describes the end to end process from the analysis to the publication of the NOA report and identifies the roles and responsibilities of the Electricity System Operator (ESO) and onshore Transmission Owners (TOs). The holistic network design (HND) and offshore transmission network review (OTNR) are considered in our NOA work.
