2604 NEW ZEALAND GAZETTE, No. 98 12 JUNE 2008

Notice

1. Title and commencement—(1) This notice is the
   Electricity Governance Regulations (Exemption No. 86
   (Transpower New Zealand Limited)) Exemption Notice

(2) This notice comes into force on the day after the date it
is notified in the New Zealand Gazette.

2. Exemption—Transpower New Zealand Limited, in its
   capacity as system operator (“system operator”), is granted
   an exemption from compliance with Rule 6 of Section IV of
   Part C of the Electricity Governance Rules 2003 (“Rules”).

3. Terms and conditions—This exemption is granted on
   the following conditions:

(a) The exemption only applies to the system operator
in relation to its intended contract with Genesis
Power Limited to offer frequency keeping from
Genesis’ Huntly Power Station;

(b) the exemption only applies to the system operator’s
obligation to use reasonable endeavours to enter into
a contract with Genesis that contains obligations on
Genesis to:

(i) provide one or more generating units at Huntly
Power Station that collectively provide a
response rate of at least 10 MW per minute
when the grid frequency error is greater than or
equal to 0.05 Hertz, as required under Rule 87
of Schedule C5 of Part C of the Rules; and

(ii) maintain the frequency of the grid at all times
to within the normal band, as required under
Rule 88.2 of Schedule C5 of Part C of the
Rules; and

(c) the system operator must use reasonable endeavours
to ensure that its contract with Genesis (if any)
relating to the provision of frequency keeping
services based at Huntly Power Station states that
Genesis must:

(i) provide an average response rate of at least
10 MW per minute when the grid frequency
error is greater than 0.2 Hertz (that is, when the
grid frequency is outside the normal band) over
periods specified in the contract (being not
less than 24 trading periods in duration, which
trading periods may or may not be contiguous);
and

(ii) ensure the standard deviation of the grid
frequency over periods specified in the contract
(being not less than 24 trading periods in
duration, which trading periods may or may
not be contiguous) does not exceed the
maximum allowable standard deviation
specified in the contract, such standard
deviation to be determined by reference to the
system operator measured frequency but
excluding any frequency measurements that are
outside the normal band.\n
4. Reasons for granting the exemption—The reasons for
granting this exemption are:

(a) It is necessary and desirable that the system operator
is able to secure a reasonably reliable extra non-
hydro resource for providing frequency keeping
given the dry conditions of winter 2008. Providing
frequency keeping services from a thermal (rather
than hydro) means that water may be conserved
and/or used more efficiently for energy generation;

(b) the system operator has advised that the generating
units at Huntly demonstrate an average response rate
of 10 MW per minute over a 9 hour period, and that
the generating units at Huntly demonstrate an
acceptable standard deviation over a minimum
period of 12 hours. This level of performance does
not affect the system operator’s ability to comply
with its principal performance obligations as set out
in the Rules; and

(c) securing a new plant to provide the frequency
keeping may also lower the costs borne by the
industry for acquiring the service. This is because it
may create downward pressure on frequency costs
due to added competition between the providers of
frequency keeping services.

5. Urgency—(1) This exemption is granted under urgency
   in reliance on subclause (4) of Regulation 194.

(2) This exemption expires at the close of 5 September
2008.

(3) Pursuant to Regulation 194(5)(c), the Commission will
publicise the exemption on the Commission’s website and
will have regard to any views that participants make known
to it by 4.00pm on 27 June 2008.

Dated at Wellington this 10th day of June 2008.

For and on behalf of the Electricity Commission:

DAVID CAYGILL, Chair.
