GC0130: OC2 Change for simplifying ‘output useable’ data submission and utilising REMIT data

This modification is responding to feedback from the industry on the current use of the OC2 process to provide Generator Output Useable (GOU) and outage data. The proposed solution will simplify the data submission process such that Generators/Interconnectors will be able to submit OC2 data either via REMIT, or a new National Grid Electricity System Operator (NGESO) platform (previously TOGA-GOAMP), removing duplication for many. Changes to the OC2 requirements will lead to improved data quality on which calculations of Margin and Surplus will be made and reported to industry.

Low Impact:   Most Generators who already meet REMIT obligations would no longer also need to submit data to the NGESO platform. Generators/Interconnectors can submit data via the new NGESO platform if they do not have REMIT obligations.

The process of moving Generators to either the new NGESO platform or REMIT system is a separate process which is being managed outside the Grid Code 

When OC2 is updated, data can be submitted by Generators either via REMIT or the new NGESO platform. This will create simplifications for both NGESO and Generators.
