What does TERRE mean for GB?
8
• New post gate-closure time
balancing auction (similar to
existing day ahead arrangements)
• Additional process for submitting
offers to TERRE in line with
Balancing Mechanism processes.
• SO will have an additional tool to
conduct coarse energy balancing
actions etc using 15 min blocks of
energy
• Access to additional flexibility such
as “non-BM” units and across
borders for energy balancing.
• New international market for GB
market participants to compete in.
• Introduction of new pay-as-clear
pricing approach (in parallel with
existing arrangements)
• Removal of barriers to entry for
“non-BM participants” and an
increase in price formation
• Estimated reduction in balancing
costs of €13 million for GB
• Currency exchange required:
Operationally Commercially
How big is TERRE and how will it fit into our strategy?
9
National Grid conducted some analysis to understand the below questions:
How much could we use TERRE?
Use to stand down STOR earlier – 164MWh per day (7MW average)
Coarse energy balancing – 1.4GWh per day (60MW average)
Controlling I/C flows – 1.4GWh per day (60MW average)
Total yearly volume 1.10TWh out of 4.42TWh total actions – 25% of
needs
What sort of volumes could be offered into TERRE by the GB market?
Initial analysis has suggested that we could see up to 3.8GW of volume
offered into TERRE from GB market participants
Project TERRE industry day: Project TERRE
Who is ELEXON and what do we do?
■ Administer the Balancing and Settlement Code (BSC)
■ Manage imbalance Settlement arrangements and payments
■ Settle payments for actions under the Balancing Mechanism (BM)
What else does ELEXON do?
■ Training and support for BSC Parties
■ Ensures compliance to the BSC through auditing and a party performance
framework
■ Manages review and implementation of changes to existing GB BSC regulation
GB implementation of the TERRE product overview (1/2)
■ National Grid and ELEXON working together to deliver TERRE
– National Grid: the Grid Code
– ELEXON: the Balancing and Settlement Code
■ Changes required to both Codes in order to implement the necessary arrangements to
facilitate the TERRE balancing product
■ BSC: P344 ‘Project TERRE implementation into GB market arrangements’
■ Grid Code: GC0097 ‘Grid Code Processes Supporting TERRE’
■ Due to interdependencies between the Codes for TERRE, ELEXON and National Grid have
facilitated cross-Code working
– Working together utilising internal and industry resource to deliver an aligned, efficient
TERRE balancing product to the market

■ Allows the association of MSIDs to a BM Unit for the purposes of offering Balancing
Services only, i.e.
– Lead Party of a Secondary BM Unit are not responsible for consumption at those
Meter Points
– Metered volumes not used to calculate Imbalance Positions
– Metered volumes will be used to calculate Non-Delivery volumes
■ Secondary BM Units requirements :
– Half Hourly SVA MSIDs only
– MSIDs are in the same GSP Group
– MSID can only be in one Secondary BM Unit at any time
– Secondary BM Unit Monthly Charge

System Operator Guideline (SOGL) Article 162 describes the process
RR prequalification process
A potential RR provider shall demonstrate….. that it complies with RR technical minimum
requirements … in Article 161
Within 8 weeks of receiving the formal application the TSO shall confirm that the
application is complete (in terms of information required)
If the application is incomplete the RR provider shall provide the additional required
information within 4 weeks of the request from the TSO (if the provider does not comply
the application is deemed to be withdrawn)
Within 3 months from the confirmation of completeness the TSO shall confirm if the
potential RR provider meets the criteria for prequalification
Qualification will be reassessed
At least once every five years
Where technical requirements or equipment changes

System Operator Guideline (SOGL) Article 161 gives minimum technical requirements
Shall comply with activation and de-activation according to set point from TSO
Time stamped scheduled active power output for each RR providing unit and
group (and each generating module or demand unit of a RR group) with
maximum active power >= 1.5MW
Time stamped instantaneous active power output for each RR providing unit
and group (and each generating module or demand unit of a RR group) with
maximum active power >= 1.5MW
Fulfilment of availability requirements
TSO shall specify RR availability requirements and requirements for control
quality
The RR provider will inform the TSO about actual availability or forced outage

At go-live will assume all existing active BMUs pre-qualify
(one off exercise)
At go-live will have simple way to say whether an existing
BMU wishes to be part of TERRE
Ongoing will treat pre-qualification as separate
Operational metering* – will be down to 1MW to align with the
product (*National Grid purposes, Settlement metering also required)
Metering accuracy – 2.5%
How to indicate availability – will use MIL and MEL
Close participation between the TSO and DSO/DNO is vital
(and mandated in codes) so detailed registration process will
be agreed with DSO/DNOs

The feasibility of the returned RRAs is checked from the perspective of ramping
Adjustments are made if infeasibility is found
Replacement Reserve Instructions (RRIs) are sent to the BSPs so that the Full Activation
Times (FAT) for each 15 minute period is honoured
For the ½ hour after the TERRE delivery period Final Physical Notifications (FPNs) are not
available (the “beyond the wall issue”)

There are reasons why the GB TSO may not follow the RRA
The unit may declare a change in availability (using MIL/MEL)
The GB TSO may have issued a BOA due to interim system issues
Having issued an RRI this will be treated as a Capped Committed Level (CCL) and
subsequent Bid Offer Acceptances (BOAs) will be taken from this level
Does RRI always follow RRA/interaction with BM

Actions in the same direction:
The restriction of RRIs will occur when a BOA has been issued if deemed necessary
When a BOA has been issued before an RRI and they are in the same direction and
the BOA volume is larger than the RRI, no RRI will be issued
unit to be settled for the RRI volume using the RR Activation with the remaining
volume settled at the BOA price (i.e. the red area in the bottom left diagram)
When a BOA has been issued before an RRI and they are in the same direction and
the RRI volume is larger than the BOA, a RRI will be issued for the difference (blue
area above red area in bottom right diagram).
The RR schedule will be used to ensure that the unit is paid the TERRE clearing
price for the blue area and BOA price for the blue area.

Actions in opposite directions:
Where a BOA has been issued before an RRI and they are in opposite directions the
RRI will not be issued and the unit will continue to follow the instructed BOA output.
Option 1: By automatically unwinding the RRI at the bid/offer price in the BM
Option 2: By automatically unwinding the RRI at the bid/offer price in the BM but
capping the unwinding cost at £0
Option 3: By removing any unwinding cost for the RRI
Option 1 was chosen

The TERRE product has a maximum Full Activation Time (FAT) of 30 minutes
FAT = preparation time + ramping time
The Central TERRE programme wishes to incentivise product shapes that start to ramp 5
minutes before the RRA and complete 5 minutes into the RRA
This is to reduce imbalance caused by interconnector ramping

15 min RR Acceptance Period
P344 solution has set BEDP = £0
15 min RR Acceptance Period
How will QH RR Acceptances volumes be Settled?
Why is it needed?
■ National Grid have indicated they will not always issue a full RR Instruction.
■ Settlement needs to account for all TERRE volumes for Non-Delivery purposes. Therefore the SAA will
construct an ‘RR Schedule’ for use in settlement to account for the instances where a RR Instruction is not
received.
■ The RR Schedule will respect the BM Unit declared Dynamic Data Set (where possible) and align with TSO
RR Dispatch Principles (as defined by National Grid)
■ RR Schedules will be treated as Acceptance Data issued 60 min prior to the RR Auction Period and act as
baseline for any subsequent Acceptance Data received.
Quarter Hour RR Acceptance Data
RR Schedule
15 min RR Acceptance Period
How will QH RR Acceptances volumes be Settled?
How will the volumes be Settled?
■ The volumes relating to RR Schedules are not included in any cash flow calculations
■ Therefore SAA will need to differentiate and calculate RR Schedule Volumes independently
– i.e. an equivalent calculations to those for those used to settle BOAs (Period Accepted Offer Volume
and Period Accepted Bid Volume)
■ This will ensure that the volumes for RR Acceptances and BOAs do not mix,
– which could result in a BSP being paid twice (once via RR Cashflow and again via BM Cashflow).
■ Note – in the majority of cases settlement will receive RR Instructions from the TSO but will not calculate
any associated volumes (as they would be duplicate due to the RR Schedule) will be calculated.
Quarter Hour RR Acceptance Data
RR Schedule
15 min RR Acceptance Period
How will Non-Delivery work?
■ RR Schedule will be treated exactly the same as BOA for calculating Non-Delivered Volumes
■ However the RR Schedule shall not be entered into the pricing stack for the apportionment of Non-
Delivered volumes to Accepted Balancing Services Bids / Offers
■ Instead Deemed Standard Product Offer Volumes (priced at the RR Acceptance price) and RR Deviation
Volumes (priced at BEDP = £0) shall be entered
Expected Meter Volume = FPN + RRAO

Yes VLP will be obligated to register all MSID Pairs they wish to allocate to a Secondary BM Units centrally with Settlement on the ‘SVA Metering System Balancing Services Register’. VLP will also provide ‘Delivered Volumes’ per MSID Pair so that Settlement can aggregate per Supplier per Secondary BM Unit an appropriate adjustment to applied at the Supplier BM Unit level
YES A Secondary BM Unit can contain SVA Metering Systems registered by many Suppliers in their Primary BM Units
Will the Imbalance Price Calculation be affected?
P344 proposes that the calculation of imbalance prices should include all the physical actions taken on the GB system, but only those taken to meet a GB need should be treated as priced.

QH RR Acceptances will not state whether they are to fulfil a local or foreign need P344 proposes that actions (volumes/prices) are calculated at an aggregate level for each QH.

P344/GC0097 Implementation Timescales
■ Following Parallel Running, go-live window for the Central TERRE Project will
commence
■ TERRE product will be used for live balancing of the Transmission System and
payments made through Settlements
■ Implementation date therefore needs to account for this:
–Code implementation date expected to be Q2/Q3 2019
–GB go-live date expected to be Q3 2019
■ Hope to have further information by April 2018 on Central TERRE Project
progress
–More detail on the GB implementation framework will then become available
