Appendix D: DNSP survey questions

Section 1: Export Service Quality Metrics

Background

The table below summarises the input data required to calculate the shortlisted metrics. The questions in this section aim to determine the availability and format of these data.

Do you have any initial comments about the coverage of the proposed list of metrics? Are there aspects relevant to export service quality you think are missing from this list?

(More details and context of each metric can be found HERE, but are not otherwise necessary to complete the survey).

Q1 The proposed metrics may need to be calculated at a system level, feeder level or customer level. Therefore, we'd like to determine the data available at different locations to calculate and communicate these metrics. What percentage (%) of data access do you have across your network at the following levels:

Insert percentage of data coverage

Distribution substation (A) (5)

Customer connection (B) (1)

Inverter ACside (C) (2)

Customer consumption, including self-generation (D) (3)

Voltage (1)

Active power (2)

Reactive power (3) o Yes (please provide more details below) (1) o No (2) o Not sure (3)

Q2 What is the maximum frequency at which these data are recorded at each metering point?

Q3 Looking to the future, does your organisation expect to develop new strategies (e.g., install monitoring equipment, develop estimation methods etc.) to increase the network visibility and access to customer-level data (Locations B, C, D) in the next 5 years?

Q4 How easy or difficult is for your organisation to report the following system data?

Number of customers with DER (1) o o o o o

Number of customers with DER by feeder type (CBD, urban, short rural, long rural) (2)

Number of customers with DER by size (e.g., less than 30kVA, between 30kVA and 100kVA, and greater than 100kVA) (3)

Number of customers with DER by technology (PV, Battery, EV, Wind) (4)

Number of customers with a static (fixed) export limit* determined by a connection agreement. *Includes customers whose static limit is higher than their installed capacity (7) o o o o o o o o o o o o o o o o o o

Number of customers with flexible export limit (e.g., DOEs) (8) o o o o o

Q5 For any data noted above as 'somewhat difficult' or 'extremely difficult' please provide additional context below.

Q6 How easy or difficult is for your organisation to report the following customer-level data?

Q7 For any data noted above as 'somewhat difficult' or 'extremely difficult' please provide additional context below.

Q8 How does your organisation currently access and download solar irradiance data? (select all that apply)

Solcast portal subscription (1)

Bureau of Meteorology (BOM) data (2)

Do not currently use irradiance data (4)

Other (please specify) (5) ________________

Not sure (3)

Q9 How easy or difficult is for your organisation to report the following customer complaints data?

No. of customer complaints related to overvoltage events (1) o o o o o

No. of customer complaints related to curtailment events o o o o o

No. of customer complaints with assigned jobs (4) o o o o o

No. of customer complaints resolved (i.e., assigned jobs have been completed) (5) o o o o o

Q10 For any data noted above as 'somewhat difficult' or 'extremely difficult', please provide additional context below.

Q11 In your opinion, would the format in which your organisation captures customer complaints data need to change in order to isolate issues specifically related to quality of customer export services?
