Item 4: Site Specific Correction Factors
GNI Presentation to GMARG
Agenda
• Overview of Site Specific Correction Factors
• Proposal
• Next Steps
• Appendices
7
SSCF – background
• Gas Networks Ireland conducted a review of the application of Site Specific Correction Factors at large NDM Gas
Points;
• Site Specific Conversion Factors (SSCF) apply to certain categories of NDM gas points that:
‒ Do not consume enough gas to warrant a volume corrector but
‒ Which should have a specific factor applied as opposed to a generic correction factor
• There is a requirement for a Site Specific Correction Factor ’SSCF’ to be applied to NDM Industrial & Commercial
sites which meet the following criteria:
‒ The Annual Quantity ‘AQ’ is greater or equal to 732,000 kWh and/or
‒ The Gas Point Running Pressure is greater than 25mbar; and
‒ Where Volume Conversion Devices are not in place.
• Policy approved by CER in 2006 as part of Market Opening developments
‒ Dealt with moving to new regime of Third Party Access and its impact on existing connections
‒ Policy also detailed how SSCF would be determined for new connections going forward
• The implementation of the existing SSCF Policy was reviewed recently together with the UK Methodology
8
Energy content of delivered gas depends on the number of molecules delivered and the energy content of the molecules:
Energy = Vactual x Volume Correction Factor x Energy Conversion Factor
9
SSCF requirement
Measured
volume at meterAdjustment factor based on pressure and
temperature of gas to derive a
standardised volume
Heat content of standardised
volume of gas, CV
Volume Correction Factors ensure accuracy of, and fairness, of billing between different off-takes.
For loads other than the largest with sophisticated volume correction devices but which exceed
732,000 kWh or which are supplied at higher than normal gas supply pressures Site Specific
Correction Factors are applied.
The SSCF to apply will be determined based on the following meter specific elements:
• meter gauge pressure
• altitude of the meter
• geographical supply area (one of ten areas)
• supply from medium pressure system
• meter location (inside/outside)
• temperature compensation applied (yes/no)
10
SSCF determination
All of these factors affect either the actual or expected
pressures/temperatures at the meter.
SSCF – Data required to determine accurate SSCFs
• Site specific locational data should be available from site visits and the Geographical
Information System (altitude)
• GNI Asset Operations carry out Function Checks at NDM Sites:
‒ All meters ≥G400 are function checked yearly.
‒ Medium Pressure ≥G100 – G250 are function checked every 2 years.
‒ Low Pressure ≥G100 – G250 are function checked every 3 years.
‒ All Modules ≥G20 – G65 are function checked every 5 years.
‒ As part of the I&C Meter Replacement Project & I&C Safety Surveys there is a function
check carried out.
• An outcome of this activity is that changes to Gas Point Running Pressure values
have been observed
11
• Many NDM Sites are availing of Gas Pressures greater than 25mbar
• This results in higher gas pressure at a number of NDM Sites which means that
such customers receive a benefit by consuming lower gas volumes as metered;
• For the same corrected volume the measured volume would be greater if operating
at a lower pressure
• These customers are receiving lower bills from their Shippers
• This is also having an impact on Distribution Shrinkage and currently being paid for
by all Distribution system users (possibly accounting for up to 10% of Distribution
UAG)

• The remaining Gas Points are scheduled for site visits;
• Approximately 1,500 to 1,600 Gas Points in total are eligible
for SSCFs.

Unit Rate applied = Average SAP for 2014: € 0.02119549 per KWh
This relates to wholesale SAP price only. In practice the financial impact on the End User could
be three times this as the Shipper will be charging a retail price in the region of 6 cent/KWh
when you include transportation, fixed costs etc.

Impact of SSCF Changes
Existing New No SSCF
SSCF – Medium Term Impact
• The introduction of a new SSCF policy could see Distribution UAG (which is paid for by all customers reduce by as much as 10%)
‒ It is a fundamental part of the Distribution tariff regime
‒ Another solution would be to install more volume correctors but the costs totally outweigh the benefits (circa. €1,100 per site)
• More accurate and fairer application of metering for large NDM sites that do not justify the cost of a volume corrector
• More accurate and fairer application of metering for large NDM sites based on the Gas Point Running Pressure at the site
18
GNI Proposal
• GNI to use most recent Pressure values to calculate revised SSCFs.
• Revised SSCFs values to become applicable on 1st October, 2015.
• GNI are proposing not to apply retrospective adjustments to sites that do not
currently have a SSCF or to sites with revised values.
• GNI will cap any upward adjustments at 3% per annum (69 sites).
• GNI will apply retrospective adjustments to sites where over allocations of greater
than 3% have taken place (6 sites) – 1 year or to date of Pressure Reading which
ever is the longest – this will be provided via an AC Read.
19
• Certain customers will require retrospective rebates, processed through their
Registered Shipper;
• New SSCF factors applied from 01 October will see impacts on KWhs
registered at affected sites (some higher, some lower)
20
What does it mean for Shippers?
• Proposal to be considered by Shippers and feedback to be provided by
Friday, 4th September, 2015;
• Draft Procedure to be considered by Shippers and feedback to be provided
by Friday, 4th September;
• The Draft Procedure provides:
‒ Details of the SSCF Methodology;
‒ Proposes a Monthly Review Process;
• Revised SSCF values will be applied from 1st October, 2015
21
Next Steps
Appendices
• Energy = Metered Volume x Calorific Value x CV Zone Correction Factor x Gas
Point Correction Factor/ 3.6
• CV Zone Correction Factor = 1 for NDM Sites with a SSCF;
• Gas Point Correction Factor is not equal to 1 for NDM Sites with a SSCF;
• Gas Point Correction Factor = 1 for NDM Sites that do not meet the SSCF criteria;
• The CV Zone Correction Factor and Gas Point Correction Factor values are sent to
Shippers in any Market Message containing a Meter Read; e.g. M803N.

July-15 PPM Review – Meter Installation Stats
Overview‒ Total consuming PPM Population 95,951 (as of 05/08/2015)‒ This represents 15.1% of the Total NDM Residential Population
This is a switch of 0.9% of the entire NDM population to PPM in past 12 months.‒ Gas-card Services are now available at >1,430 Payzone Outlets nationally.
Meter Installations ‒ 1,033 PPM Meter fits per month (based on 12 month rolling average)‒ PPM Installations are broken into 3 groups;
1) PPM Meter Fit (21) 2) Credit Meter to PPM Exchange (629) 3) PPM to PPM Exchange (183)‒ 78% of all PPM meter installations in July were new PPM installations, the remainder were PPM-PPM exchanges.‒ 833 PPM Meters were installed in July
Average new PPM fits per month over last 12 months = 650 meters.
Financial Hardship
‒ 63,426 Financial Hardship PPM meters have been installed since the project began in 2009.
567 Financial Hardship meters installed in July 2015.
30,250 Financial Hardship Meters have been installed under PC3 out of an allowance of 40,923.
‒ 68.1% of all meters fitted in the last 12 months were assigned Financial Hardship.
