Purpose of OC10
OC10 sets out the requirements for written reports for significant incidents that were initially reported orally under OC7.
OC10 also sets out the mechanism for a joint investigation if NG and the relvant users agree.
OC10 applies to:
- Network Operators
- Non embedded customers
- If NG determines the originally reported event to be a significant incident, the user will have to submit a written report
- If the user determines the originally reported event to be a significant incident, NG will have to submit a written report, which the user may NOT pass on.
- A network operator may use the information in the written report to prepare a report to a generator with a generating unit on the system or another network operator of another system connected to theirs.
- A generator may use the information in the written report to prepare a report to another generator with a generating unit connected to the same system or a network operator on another connected system.
- If we were to witness a trip at a station, which could be due to a grid fault, then we should consider issuing NG an OC10 to find out whether a grid fault as caused the trip. We should first phone NG to inform them of the intention to raise a significant incident report and then follow this up in writing via fax.
What is a significant incident?
- Generating substantially over a PN/MEL
- Syncing more than five mins early
- Desyncing more than five minutes late
- Generating without a PN
- Breaking the Grid Code
A full report must be submitted, within 2 hours of recieving oral notifications under OC7.
NG or a user who has recieved a written report can request investigation.
All rules and procedure for a joint investigation will be agreed between NG and the users - if no agreement can be made then there will be no joint investigation. A request for a joint investigation must be made in writing.
