 What to query and where to find it
 Conclusions
 Questions

Training objectives
At the end of this session you will:
 Have an understanding of your rights with regard to raising Formal
Queries and Disputes;
 Know where to find the right data to check;
 Be advised on how to increase the effectiveness and the efficiency of
the Formal Queries process.
3
Background
 Inefficiencies in the management of Data and Settlement Queries, were
identified at the working group for Mod_38_10 held in February 2011;
 SEMO proposed a training session to facilitate the understanding of the
process;
 Training material available to Participants has been updated.

Data Query – Original Training
Data Queries need to be filed within the DVP
Data Verification
Period 4 Working
Days
DVP commences immediately after the MSQs
have been issued
SEMO has to resolve the Data
Queries within 10 working days,
otherwise they effectively
become Settlement Disputes
SEMO Determination Period
10 Working Days
Dispute Raising
Period 5 Working
Days
Should the Participant not
agree with the result of the
MO, can a Settlement
Dispute be raised

Data & Settlement Query Process
Re-calculate
- Only Data Queries can cause a Re-price;
- A Re-price must be carried out within one month of the resolution of the
Query;
- A Re-price will only be carried out in cases of variances greater than the
Settlement Recalculation Threshold (SRT).

Data & Settlement Query Process
Re-calculate
- Variances to Settlement items always cause a Resettlement;
- The timelines of a Resettlement are dictated by the materiality of the
variances:
- High materiality variances > €50,000 must be completed within one
month
- Low materiality variances < €50,000 will be included the next
timetabled Resettlement (M+4 or M+13)

• Data Queries
within 10 working days
• Settlement Queries
within one calendar month
- If timelines are not respected, the query will automatically
become a Dispute

Data & Settlement Query Process - Right to Extend
Right to grant extensions
-
SEMO can request additional time to resolve a Data or a
Settlement Query.
-
This is limited to an additional 10 working days
-
Raising Party must give their consent to the extension
-
If no consent is received the query must be resolved within the
original timelines.

Data & Settlement Query Process - Right to Dispute
Right to Dispute
-
Participants have the right to dispute SEMO’s findings within 5
working days of receiving the resolution;
-
Participants have the right to receive a resolution within the
timelines of the T&SC else the Data or Settlement Query
automatically becomes a Settlement Dispute;
-
A General Dispute can also be raised on any claims within Party
in relation to any item in the T&SC provided that is within 28 days
of that Party having become aware of the Disputed Event and in
any event within 2 years of the Disputed Event having occurred

Data query – What to query and where to find it
As per T&SC 6.82 and 6.83 SMP and Market Schedule Quantities will be
recalculated in the event that the Market Operator in resolving a Data Query
determines that the following data has been applied incorrectly and that the
correct application would require it to change it for more than the Settlement
Recalculation Threshold:
 Commercial Offer Data or Technical Offer Data
 Actual Availability or Dispatch Quantity*
 Meter Data
 Also if Market Schedule Quantity has been calculated incorrectly
*Dispatch Quantities only impacts units with Non Firm Access Quantity
36

Settlement Query – What to query and where to find it
As per T&SC 6.94 and 6.95 a Settlement Query may be raised in respect of the
application of Metered Generation or the calculation of any of the following
amounts:









Metered Demand
Net Demand
Settlement Net Demand
Eligible Availability
Actual Availability
Dispatch Quantity
Currency Cost
Interest Amount
or in respect of Discovered Errors*
Also a Participant may raise a Settlement Query in the event of any difference
between a Settlement Item on the Ex-Post Indicative and the same Item on the
Ex-Post Initial Settlement Statements without the Participant having filed a Data
Query in relation to that Item.
*Discovered Errors, as defined in the T&SC Glossary, only relates to Meter Data errors.

 Further details on files format and contents can be found on the MPUD and
GPUD documents on the SEMO Website under

 Website content is included in the document ‘SEMO Website Go Live
Bulletin’ at http://www.sem-o.com/Publications/Pages/GeneralPublications.aspx
 This training will be updated once details of new queries for Intra-Day
Trading will be finalised with relevant files spec.
62
Conclusions
 Robust data checking must happen within the correct Data Verification
Period;
 Checks should focus at first on the set of data that will impact Pricing and
Scheduling;
 Participants are not limited to their own data; any data publicly available
can be subject of a Data or Settlement Query;
 An efficient use of the Data or Settlement Query would avoid delays in
finalising Market results and limit the need to refer to the Dispute process.
