Planned MIDP outage on Tuesday 12 December 2017 – Impact on BMRS System Price calculations

What is happening?
ELEXON has been advised by one of the Market Index Data Providers (MIDPs), EPEX SPOT power UK, of a planned outage due to take place on Tuesday 12 December 2017 between 18:40 (BST) and 22:00 (BST).

This means the Market Index Data used to calculate the Market Index Price will not be provided to BSC Central Services by this MIDP for Settlement Periods 41-43 (inclusive).

How will I be affected?
Since the implementation of BSC Modification P305 ‘Electricity Balancing Significant Code Review Developments’, the Market Index Price (MIP) is only used for specific defaulting situations in the Imbalance Price calculation. These situations include having a Net Imbalance Volume (NIV) of zero or having no First Stage Unflagged actions in the stack to set the Replacement Price. In the unlikely event that the MIP is needed and no data is available from the other MIDP (N2EX), the default price applied will be zero.
Data for the planned outage period will be provided by the MIDP for use in the Interim Information (II) Settlement Run. The System Prices will be re-calculated if necessary and published to BSC Parties via data flows and in Best View Prices on the ELEXON Portal.
The Balancing Mechanism Reporting Agent (BMRA) will not re-run indicative Settlement calculations on any impacted Settlement Periods when the planned outage is completed. Therefore, prices posted on the BMRS website will not be updated retrospectively.
Do I need to take any further action?
