OPEN SESSION – DECISION PAPER

1. Metering Dispensation D/534 Seagreen Offshore Wind Farm (site specific or generic)- (SVG251/03)

1.1 The current Settlement metering Codes of Practice (CoPs) only cover Metering Equipment designed for Alternating Current (AC) circuits. Seagreen Wind Energy Limited (SWEL) has applied for a site specific Metering Dispensation (D/534) from CoPs 5 and 4, for a solution to the issue of metering its Low Voltage Direct Current supplies on its Seagreen Offshore Wind Farm.

The SVG:

• APPROVED Metering Dispensation D/534 against Codes of Practice 5 and 4, on a lifetime basis, as a generic Metering Dispensation and also to amend D/534 to capture the solutions already covered by D/461 and D/474, and then end-date registrations against them; and
• NOTED we will present a similar paper to the Imbalance Settlement Group, with a similar recommendation, in respect of CoP4 only.

2. Metering Dispensation D/535 –   CP1527 Implementation Date – (SVG251/07)

2.1 Issue 97 – “Meter shortage risk driven by global materials availability and supply chain challenges” was raised on 20 August 2021. It aims to understand the risk to BSC processes such as New Connections and Meter exchanges caused by the current Meter shortage and recommend any potential mitigation options that may be required.

The SVG:

• APPROVED Metering Dispensation D/535 against Codes of Practice 3, 5 and 10 on a temporary basis for 18 months from the implementation date of CP1527 (June 2022), as a generic Metering Dispensation; and
• NOTED that a similar paper was taken to the Imbalance Settlement Group, with similar recommendations, in respect of CoPs 1, 2 and 3.

3. Metering Dispensation D/536 –   Recalibration of Meters (CoPs 3 and 5) – (SVG251/08)

3.1 Issue 97 – “Meter shortage risk driven by global materials availability and supply chain challenges” was raised on 20 August 2021. It aimed to understand the risk to BSC processes such as New Connections and Meter exchanges caused by the current Meter shortage and recommend any potential mitigation options that may be required. This Metering Dispensation proposes to grant a derogation from CoP4 Appendix A for the requirement to re-calibrate Meters registered against CoPs 3 and 5 as recommended by the Issue 97 Working Group.

The SVG:

• APPROVED Metering Dispensation D/536 against Code of Practice 4 on a temporary basis for 18 months, as a generic Metering Dispensation on the condition that any Meters that were due for calibration in the time period (18 months from approval) for which the Metering Dispensation applies should be re-calibrated or replaced within two years of the end date of this Metering Dispensation.
• NOTED a similar paper was taken to the Imbalance Settlement Group, with similar recommendations, in respect of CoP 4.

4. MDD Change Requests for Versions 319 – (SVG251/01)

4.1 This paper invited the SVG to approve eight General Change Requests and note 13 Fast Track Change Requests, for implementation in Version 319 of Market Domain Data (MDD) with a go-live date of 26 January 2022.

• APPROVED eight General BAU Change Requests for implementation in MDD 319 with a go-live date of 26 January 2022
• NOTED 13 Fast Track Change Requests for implementation in MDD 319 with a go-live date of 26 January 2022.
