Transpower Security of Supply Annual Assessment 2024

Security of Supply Annual Assessment 2024
Generator, Distributor and Demand Response Survey COMMERCIALLY SENSITIVE [1]

This template forms the basis for generation and demand response capability reporting from electricity generators, distributors and major electricity users to the System Operator for the preparation of the Security of Supply Annual Assessment.

If a particular field does not apply to you, then please leave blank.

Feel free to add explanatory comments at the end of the survey.

If any major outages are known that will affect availability from April to October, please inform the System Operator.

If you require a resubmission please click the link again and comment at the bottom that this is your latest submission. There is an option to review before submitting.

Please email market.operations@transpower.co.nz if you have any issues or questions regarding the survey.

Please complete by Tuesday 13 February 2024

[1] As in past years we would like to provide the capacity factor of existing hydro plant to the Electricity Authority to update the Hydrological Modelling Dataset. Unless advised otherwise, we will provide this information (limited to existing hydro generation capacity factors only) to the Electricity Authority.

Notes:

1. GIP or nearest GXP for embedded generation.

2. Capacity at the connection to the AC transmission or distribution network

3. Capacity factor that is expected in a normal/average year. For generation only.

4. Expected generation in a normal/average year.

5. Cumec/MW is the average conversion factor for a hydro station.

6. Heat rate is the average efficiency ratio in GJ/GWh for that thermal fuel. Please state in the Notes column if this is provided on a HHV (GCV) or LHV (NCV) basis.

7. Enter yes if generation is limited by thermal fuel supply constraints.

8. Only provide information for 'grid scale' batteries of at least 5 MW in capacity (irrespective if directly connected to the transmission grid or not)

9. 1 = Decommissioning activities have been financially committed to and/or commenced, 2 = Dependent on market conditions, 3 = Uncertain

6. Thermal fuel supplies for electricity generation:

2. Please provide table by month if applicable.

3. Please specify units.

4 Indicate if the contract ends within a year and the date that it does so

5. Indicate any short-term delivery issues that you feel are important

8. Please complete the table below for new generation or grid scale battery storage (See notes below and scroll to the far right to complete all columns):

Notes:

a. GIP or nearest GXP for embedded generation.

b. Indicate whether the new generation or grid scale battery storage is consented or not, and whether it is proceeding or on hold.
Please use the following five categories when classifying your projects:
1) Consented and proceeding
2) Consented and on hold/awaiting market conditions to change
3) Consented, and on hold/awaiting market conditions to change. But for this project the consent requires revision or reconsent.
4) Not consented, but consent is likely to be sought within the next 2 years
5) Not consented, long term project for which consent is not expected to be sought within two years.

c. If there is no commissioning date, please leave blank. We will use generic values.

d. Capacity at the connection to the AC transmission or distribution network

e. Capacity factor that is expected in a normal/average year. For generation only.

f. Expected generation in a normal/average year.

g. Cumec/MW is the average conversion factor for a hydro station.

h. Heat rate is the average efficiency ratio in GJ/GWh for that thermal fuel. Please state in the Notes column if this is provided on a HHV (GCV) or LHV (NCV) basis.

i. Only provide information for 'grid scale' batteries of at least 5 MW in capacity (irrespective if directly connected to the transmission grid or not)

9. Please complete the table below for existing Demand Response/Interruptible Load (See notes below and scroll to the far right to complete all columns):

Notes:

Only provide information for Demand Response/Interruptible Load resources with cumulative installed DR/IL Capacity (2) of at least 5 MW.

1. GIP or nearest GXP if known

2. DR/IL Capacity is the maximum MW demand reduction from the Demand Response/Interruptible Load resource.

3. Peak Factor is the fraction (between 0 and 1) of the DR/IL Capacity that is expected to be available to respond at time of winter (1-Apr to 31-Oct) peak demand

10. Please complete the table below for new Demand Response/Interruptible Load (See notes below and scroll to the far right to complete all columns):
