A Total Shutdown of the Total System; or
A Partial Shutdown of one or more parts of the Total System.
If and when normal BSC market operations shall be suspended;
How and when normal BSC market operations, if suspended, shall resume; and
Claims for black start compensation amounts, as submitted by the Lead Parties of BM Units which have received black start instructions from the NETSO (as defined in BSC Section G3).
A Black Start Period (during which the BSC’s Black Start contingency provisions apply, but normal BSC market operations are not necessarily suspended); and
A Market Suspension Period (during which normal BSC market operations are suspended).
If there is a Total Shutdown, then both a Black Start Period and a Market Suspension Period will exist. The Market Suspension Period will last for the entire duration of the Black Start Period.
If there is a Partial Shutdown, then a Black Start Period (but not necessarily a Market Suspension Period) will exist. A Market Suspension Period will only exist if, at any time during the Partial Shutdown, the Market Suspension Threshold specified in BSC Section G3 is met. In practice, there may therefore be a Market Suspension Period for some, all or none of the Black Start Period. If the Market Suspension Threshold is met, then the Market Suspension Period will last for the remaining duration of the Black Start Period.
Suspending the operation of the Balancing Mechanism (including the submission and acceptance of Bids and Offers);
Suspending the TERRE Market (including the submission and activation of Replacement Reserve bids);
Suspending the notification of contract volumes (Energy Contract Volume Notifications and Metered Volume Reallocation Notifications);
Suspending the calculation of Energy Indebtedness, and thereby Parties’ credit positions; and
Suspending the normal imbalance pricing calculations and applying a Contingency Imbalance Price (as defined in Section 1.6 of this BSCP) to all Parties’ Metered Volumes.
Any instructions to Black Start Stations and to Network Operators which are part of an invoked Local Joint Restoration Plan (unless the NETSO specifies otherwise); and
In Scotland, any instructions to Gensets that are not at Black Start Stations, but which are part of an invoked Local Joint Restoration Plan and are instructed in accordance with the provisions of that Local Joint Restoration Plan.
The Lead Party’s Avoidable Costs; minus
The imbalance charges received, or reduction in imbalance charges paid, for the black start compensation volume.

The NETSO will contact relevant Grid Code Users to invoke Local Joint Restoration Plans and begin the restoration of the Total System.
The NETSO will work towards restoring the Total System (period from ‘Point A1’ to ‘Point B’).
The NETSO will inform BSCCo that a Total Shutdown exists and that it intends to implement a Black Start (the NETSO will subsequently inform BSCCo, in its reasonable opinion, of the time and date of the shutdown, known as ‘Point A2’).
After receipt of the NETSO’s notification, BSCCo will communicate the existence of a Black Start Period and Market Suspension Period to all BSC Parties, BSC Agents, and any CM Settlement Services Provider as soon as normal communication channels2 become available.
Where data is not available, the relevant Settlement Runs will be delayed in accordance with Sections T1.4.2 and T1.4.5 of the BSC. The FAA shall then take appropriate action with regard to the Payment Date in accordance with Section N6.6 of the BSC.
Based on its investigations, the NETSO will determine in its reasonable opinion the start time and date of the Total Shutdown and will notify BSCCo.
After receipt of the NETSO’s notification, BSCCo will establish the corresponding Settlement Period/Day and will communicate this as the start of the Black Start Period and Market Suspension Period to all BSC Parties, BSC Agents, and any CM Settlement Services Provider.
When the Transmission System is energised, the NETSO will inform BSCCo.
BSCCo will pass this information on to BSC Parties, via normal communication channels, with the caveat that the market is still suspended and individuals may not have power, hampering their ability to receive those communications.
The NETSO will work to restore its BM systems, which are capable of communications with Grid Code Users. Grid Code Users and BSCCo will be informed when the systems have been restored and are therefore available and capable of operation.
BSCCo will pass this information onto BSC Parties.
BSCCo will work with BSC Agents to restore the BSC Systems. When the BSC Systems are restored, BSCCo will inform the BSC Panel and BSC Parties that the BSC Systems are available and capable of operating. Refer to Section 2.2 of this BSCP for more detail on the Black Start requirements of the BSC Systems.
At this point, the Transmission System has been re-energised in accordance with OC9.4.7.9; generators are able to generate sufficient electricity to meet Demand and are under instructions of the NETSO through the NETSO’s BM system; and the BSC Systems are available and capable of operating.
The NETSO will inform BSCCo and Grid Code Users of the time and date that the Total System could return to normal operation under the Grid Code. BSCCo will convey the information contained in these updates to the BSC Panel and BSC Parties via normal communication channels.
The NETSO will inform BSCCo of any circumstances which are likely to affect the calculation of a Contingency Imbalance Price (see Section 3.4 of this BSCP for further details).
At the start of ‘Point F’, the BSC Panel will determine a proposed Settlement Period/Day from which normal BSC market operations shall resume. This is ‘Point K’ on the diagram.
The BSC Panel will consult with the NETSO (and may consult with BSC Parties, Party Agents, Market Index Data Providers and the Authority) on the proposed timetable for the resumption of normal BSC market operations.
Following feedback received during the consultation, the BSC Panel will determine the point at which normal BSC market operations should resume (‘Point K’).
BSCCo will promptly inform all BSC Parties and any CM Settlement Services Provider of the Settlement Period/Day from which normal BSC market operations shall resume (‘Point K’). The NETSO will notify Grid Code Users of this ‘Point K’.
The Panel will determine / confirm the methodology to be used in the calculation of the Contingency Imbalance Price(s) (see Section 3.4 of this BSCP for further details).
The ECVAA will return to normal operations. Therefore Volume Notifications submitted by BSC Parties will be processed and reports will be issued to BSC Parties. These will include the forward contract report (ECVAA-I022) which is issued daily to each Contract Trading Party summarising notifications received relating to that Contract Trading Party for the next seven days. This will therefore show BSC Parties their contract position at ‘Point G’ + 7 days, with the caveat that their contract position is ‘zero’ up until ‘Point K’. A warning will be placed on the BMRS to remind BSC Parties that all contract positions are zero until normal BSC market operations resume (at ‘Point K’).
BSC Parties are to agree their despatch with the NETSO through this period.
It is expected that BSC Parties will begin negotiating bilateral contracts.
Between ‘Point H’ and ‘Point J’ (‘Point K’ minus 1 hour) BSC Parties can submit Volume Notifications, Bid-Offer Data and TERRE bids in relation to the first and subsequent Settlement Periods after ‘Point K’.
Between ‘Point H’ and ‘Point I’ (‘Point K’ minus 10 hours) BSC Parties should use reasonable endeavours to submit Physical Notifications to reflect their required physical position at ‘Point K’.
This point is 10 hours before normal BSC market operations are planned to resume. BSC Parties should use reasonable endeavours to submit all Physical Notifications possible for ‘Point K’ by now. The NETSO will then despatch plant to enable BSC Parties to meet their required physical position at ‘Point K’. If a BSC Party submits a revised Physical Notification after ‘Point I’, it may not be possible for the NETSO to despatch the plant in order for the BSC Party to meet this revised position.
For Settlement Periods which are to follow the start of normal BSC market operations, BSC Parties should submit BM Unit data in accordance with BC1 of the Grid Code.
At any time up to one hour before the start of the Settlement Period from which normal BSC market operations are planned to resume, the NETSO shall notify any reason why the Total System could not return to normal operation by that time. If needed, the Panel will make a revised determination as to the Settlement Period/Day from which normal BSC market operations shall resume (a new ‘Point K’). BSCCo shall promptly notify all BSC Parties and any CM Settlement Services Provider of any revised Panel determination regarding ‘Point K’, and the NETSO shall subsequently notify Grid Code Users.
If the Panel determines that ‘Point K’ should occur at a later time than originally planned, the Total Shutdown process moves back to ‘Point F’. The NETSO will continue to despatch generators up to the revised ‘Point K’.
‘Point K’ is the Settlement Period/Day from which normal BSC market operations resume.
The end of the Settlement Period immediately before this represents the end of both the Black Start Period and the Market Suspension Period.
At this point, Black Start provisions no longer apply. The Total System, Balancing Mechanism and all BSC Systems are operating normally.
No specific rules are required for any subsequent Settlement Periods after ‘Point K’, e.g. Parties can submit revised Physical Notifications up to Gate Closure.
Continue normal operation of the BMRS as far as is possible in the following manner:
The BMRS would be used to provide industry with updates regarding the status of the Transmission System and other relevant systems;
Tibco messages would continue to be issued where possible;
A notice would be placed on the BMRS stating that the indicative prices are not accurate, and that contract positions are ‘zero’, for Settlement Periods during a Market Suspension Period;
When the market returns to normal operation (i.e. point K) the BMRS would continue calculating indicative prices for subsequent Settlement Periods based on actual data received from the NETSO
The BMRS will publish the Contingency Imbalance Price information for all Settlement Periods during the Market Suspension Period, once the Panel has agreed the methodology and the price(s) has been calculated by BSCCo; and
BMRS will not receive any TERRE Market related data relating to Settlement Periods within the Market Suspension Period.
ECVAA should continue operating throughout the Market Suspension Period, where possible, as follows:
Where notifications are submitted, these will be processed and reports sent back;
‘Zero’ data is sent to the SAA for all Settlement Periods within the Market Suspension Period;
Credit Default process switched off and Energy Indebtedness for all Parties set to Zero for all Settlement Periods within the Market Suspension Period; and
Submitted Volume Notifications would be processed in relation to Settlement Periods following point K.
CDCA to continue normal operations. This would include:
Collecting data throughout the Market Suspension Period where possible; and
Aggregation runs carried out normally as far as possible.
SVAA to continue normal operations as far as possible including:
Calculation of Daily Profile Coefficients; and
Volume Allocation Runs carried out normally as far as possible in accordance with Section R of the BSC.
SAA runs would not be carried out until the Contingency Imbalance Price methodology has been determined by the BSC Panel and the price(s) has been calculated by BSCCo – see section 3.4.
FAA Payment Runs may be postponed in accordance with Section N6.6 of the BSC.

Fuel costs (including purchase, freight/transportation, storage, handling and use e.g. any changes to fuel efficiency arising from operating in accordance with the FSC);
Insurance costs (including proportion of current insurance costs applied to the period in question as well as any increase in those costs arising due to the FSC period being invoked and/or resultant claim submissions, as appropriate);
Financing costs (costs associated with funding the power station(s), via banking loan and/or via shareholder funds, using a reasonable rate of return/risk assessment);
Overhead costs (cost of running the power station(s), including those associated with staffing e.g. overtime payments, and ancillary supplies, rent,);
Maintenance costs (costs associated with day-to-day operation, ongoing maintenance and wear & tear of plant/specific apparatus);
Damages (losses in respect of damage to property e.g. plant/apparatus or death/injury to persons);
Emissions costs (cost of purchasing various emissions allowances, e.g. CO2, NOx and SOx, needed to operate the power station(s));
Industry charges (including proportion of current TNUoS and BSUoS charges applied to the claim period, and any additional charges arising from the FSC period being invoked and/or resultant claim submissions, as appropriate); and
Other costs (any additional costs necessarily and properly incurred in good faith and on a basis consistent with commercial practices and procedures that were normal and prudent, after all reasonable efforts had been made to establish that no practicable alternative action (or inaction) was available at lower cost).
defined in the BSC as “Avoidable Costs” for a Black Start Period; or
defined in the FSC as “Exceptional Costs” for FSC events
the Lead Party of the BM Unit concerned has received a black start instruction or FSC direction (as the case may be) which gave rise to those costs being incurred; and
those costs have actually been incurred by that Lead Party of the BM Unit up to the date of the interim claims submission.
Any administrative and secretarial support necessary to assist the Claims Committee; and
Any supporting information it requests which is available to BSCCo (e.g. Metered Volume data).
1 The need to invoke the Black Start process or the Re-Synchronisation of De-Synchronised Island process in accordance with Grid Code OC9.
2 This is likely to be by email, Circular or the posting of information on the BMRS website. Normal communication between BSCCo and the industry might be difficult at the start of the shutdown as the Total System will begin to be re-energised and any available communication channels could suffer from congestion/unavailability. Therefore BSCCo may only be able to communicate the commencement of the Black Start Period and the Market Suspension Period once the Total System is totally / almost totally re-energised.
3 Communication between the Authority and the Panel is to be done via BSCCo.
4 The Panel is to provide instruction on how the Contingency Imbalance Price(s) shall be applied.
5 BSCCo shall publish the Contingency Imbalance Price(s) on the BSC Website as soon as is possible as well as circulate the prices to BSC Parties.
6 Potentially CDCA runs could be affected as well as SAA runs and their timing will also be in the Settlement Calendar. The BSC Agents shall ensure all systems will operate to achieve Settlement Runs.
7 Note FSC Claims are to be submitted 60 Days (as opposed to 60 Working Days) after the end of a FSC event.
8 Claims can only be made by the Lead Party of a BM Unit who has received (i) a black start instruction from the NETSO during a Black Start Period or (ii) a Direction from the Secretary of State during a FSC event or in anticipation of a FSC event.
9 This process step is to be completed by the Panel in accordance with BSC Section G3.3.1A; however this could be delegated to the Claims Committee in accordance with BSC Sections B3.5 and B5.1.1.
10 As the scope of each claim could be different, the Claims Committee is to determine the most relevant process for assessing the claims on an individual basis.
11 The Authority may choose the NETSO (under the Grid Code), the BSC or any other method it determines appropriate for cost recovery. If the BSC is chosen to recover costs, refer to BSC Section G3.3.7 for Black Start Period claims.
12 If this claim is for an interim amount as part of an on-going Black Start Period, any amount approved cannot be claimed for as part of the final claim.
13 The calculation for the “black start compensation amount” is as per Section G3.3.2 of the BSC. Supporting evidence is required.
14 If this claim is for an interim amount, for costs incurred to date, any amount approved cannot be claimed for as part of the final claim.
15 Details of what constitutes each Cost Category for a Fuel Security event can be found in Attachment A of this BSCP.
