rate-of-change-of- Frequency setting. The TSO
shall, within a reasonable period and in any case
within no more than 28 days, discuss with the Gen-
erator whether the proposed settings are satisfactory.
The agreed settings shall be specified in the Con-
nection Agreement or other agreement.

(ii) In relation to any Generator which has agreed the

settings with the TSO under these provisions, the TSO
shall notify that Generator of any change of which it
is aware in the expected rate-of-change-of- Frequency
on the System which may require new settings to be
agreed.

CC.S2.9.3

Each Generator shall be responsible for protecting the WFPSs
owned or operated by it against the risk of damage which might
result from any Frequency excursion outside the range 52-47.5 Hz
and for deciding whether or not to interrupt the Connection
between its Plant and/or Apparatus and the Transmission System
in the event of such a Frequency excursion.

CC.S2.10 Additional Information

CC.S2.10.1

Each Generator shall provide the calculated Output for the
WFPS as part of the application for Connection of that WFPS to
the Transmission System . This will take the form of a diagram
showing wind speed and direction against electrical output in
MW ,in Wind Rose format. Following Connection , the WFPS
shall be Monitored for a period to confirm the validity of the
calculations, which may be used for future Output predictions.
This Monitoring shall be completed before a final compliance
certificate is issued. Each Generator requires a temporary com-
pliance certificate issued by the TSO in respect of each of its
WFPSs before being allowed to operate it.

CC.S2.10.2

A temporary compliance certificate may be issued to allow tests
or Monitoring that can only be performed on energised and/or
loaded Plant . After a period of time not exceeding one year from
the date on which a temporary compliance certificate takes effect
(unless the TSO in its absolute discretion agrees to extend the
validity of a temporary compliance certificate), the TSO shall
issue a final compliance certificate or indicate the reason why a
final compliance certificate cannot be issued. The final com-
pliance certificate may be issued with or without conditions
depending upon the result of compliance tests. A temporary or
