Functionality added to Kinnect Customer Solution for Modifications P376 and P419

How the P376 reforms work

VLPs and/or Asset Metering Virtual Lead Parties (AMVLPs) that manage Secondary Balancing Mechanism Units, or Suppliers that are managing Additional BM Units will be able use a baselining methodology to determine the expected energy flows for a Metering System Identifier (MSID) or Asset Metering System Identifier (AMSID) Pair in the calculation of Non-Delivery Charges and Delivered Volumes.

The new baselining process, which we will operate can work out the normal (‘baseline’) demand or generation at a site. The process will also work out the deviation from the baseline when the site is instructed to change its output by National Grid ESO.

This means that DSR providers including smaller generators and battery storage owners can be paid amounts which fully recompense them for helping to keep the system in balance.

How the Kinnect Customer Solution supports P376

Suppliers, VLPs and AMVLPs must submit Final Physical Notifications (FPNs) to National Grid ESO. The FPNs show the amount of electricity that they intend to produce or consume in any given half-hour period.

The Customer Solution will make it easier for Suppliers, VLPs and AMVLPs to submit more accurate FPNs, which helps NGESO to decide what balancing actions it needs to take. They can use the Customer Solution to submit associated data to participate in the changes. 

New file upload functionalities will also be included to facilitate the registration of Balancing Mechanism (BM) Unit Baselining Status, BM Unit Allocation Baselining details and BM Unit Allocation Event Days.

The information that can be entered by Suppliers, VLPs and AMVLPs that want to participate in the P376 reforms is:

• BM Unit (Master Detail)
• BM Unit Baselining Status
• The period that the Baselining Status value is effective for the BM Unit
• Baselining Status indication (on whether the baseline methodology will be used in the calculation of expected Settlement volumes for the BM Unit, in the period specified)

Against the Allocation of the BM Unit to the MSID / AMSID Pair :

BM Unit Allocation Baselining Details (Elexon will ensure that baseline data is consistent across related BM Unit Allocation records) including:

• The period the Baselining Details are effective for the allocation
• The Baselining Indicator identifying whether ‘Baseline’ Expected Volumes, ‘Submitted’ Expected Volumes or ‘Inactive’ No Expected Volumes (for secondary BMUs only where the site is inactive) will be provided
• The Baselining Methodology (currently restricted to the P376 methodology). 

BM Unit Allocation Event Days including:

• The event day – the day the MSID/AMSID Pair delivered a Balancing Service (or deviated from their usual generation output, or offtake at the site) and so will be excluded from the calculation of the expected volume
• Event days can be created up to 30 days in the past and are restricted to the period for which the BMU is allocated to the MSID / AMSID Pair
• The type of Event Day (currently limited to Balancing Service)
• Whether the MSID / AMSID Pair forms part of a Site Configuration operating in Differencing or with Asset Metering.

How the P419 reforms work 

P419 introduces processes so that generation, storage, combined generation and storage ,and eligible services facilities can declare themselves exempt from BSUoS charges and provide NGESO with aggregated data to this effect.

The BSC supports this as it is the primary source of aggregated metered data for a variety of non-Settlement activities, such as network charging.

How the Customer Solution supports P419 

P419 will introduce the ability for Suppliers to use the Customer Solution to submit online declarations via Kinnect. They will do this on behalf of Supplier Volume Allocation (SVA) Non-Final Demand Facility Operators to claim exemptions as described above.

The types of declarations include:

• New Declaration
• Change of Supplier
• Change of Agent
• Change of Metering System Identification number (MSID/MPAN)
• Withdraw Declaration

The SVA Non-Final Demand Facility Operators will also be allowed to submit an online Non-final demand declaration form via the Elexon Website using a web link.

This means that they can send data entered in the declaration form directly to the Customer Solution and onwards to the Supplier, which will submit it on behalf of the facility operator.

Suppliers will be responsible for checking the data and amending it if necessary before submitting it to Elexon’s Supplier Volume Aggregation Agent (SVAA) for validation. This declaration will then be approved or rejected based on the details provided. 

Additionally, all SVA Non-Final Demand declarations submitted via the website or the Customer Solution must record a company Director’s electronic signature or a Demand Site Certificate of Compliance Certificate (DUoS) in order to be considered for SVA validation.

Also, there is a validity period that allows for the submission of the DUoS after which it will no longer be acceptable. This information will be communicated accordingly.
