The National Grid Electricity System Operator (ESO) for Great Britain revealed methods to tackle inaccurate data provided by wind generators. The measures taken by the ESO are to address the inaccuracies in Physical Notifications (PNs).
The intention of announcing measures to address the inaccuracies is to reduce balancing costs and enhance the security of the electricity system, according to a report by Energy News Live.
Inaccuracies in PNs have been a longstanding issue and are increasing in severity and cost. To tackle this and reduce the impact of the inaccuracies, the ESO is planning to take several steps to increase the accuracy of the generator’s submissions.
To improve accuracy, the ESO is following a two-step process. The process involves publishing a Draft Guidance Note, which is accompanied by a consultation period. Then, a Final Guidance Note is issued.
In addition, the ESO will maintain a 6-month monitoring period. During this phase, the ESO will conduct workshops to assist the industry in improving PN accuracy.

The decision to take the initiative is not sudden. The organisation has been scrutinizing the extent of faulty information submitted for balancing purposes.
The market participants in the Balancing Mechanism were informed by the ESO and were asked to sketch their plan to collaborate with the organisation to mend the flaws in data recording.
Ofgem earlier emphasized the importance of accurate PNs, and as a result, the ESO has planned to keep Ofgem in the loop by disseminating information regarding the organisation’s efforts and concerns.
