Eye on electricity
Monitoring and investigating
We track and monitor all aspects of the energy sector and carry out enquiries, reviews and investigations into issues raised, such as out of the ordinary events.
We may be asked to look into a particular issue by an external party or by the Minister for Energy (under Section 18 of the Electricity Industry Act 2010). Our findings may result in suggestions for Code amendments, market facilitation measures or no further action. We publish all findings on the related project page.
