A084: Industry Responses

31

• No responses received from industry.

32

A084: Transporter’s View (as per July CMF Meeting)

The Transporter does not support this proposed Code Modification.

• The Transporter has no visibility of the source/transportation route of gas imported via Moffat.

• The Transporter is only aware that its shippers wish to nominate gas at Moffat.

• The Code Modification makes a strong assumption that all gas at Moffat has been short-hauled – this is not necessarily

the case (e.g. Teesside production outages).

• The Transporter wishes to note that this proposed Code Mod would impact the Disbursements Account (i.e. if relevant

shippers are to pay less for their imbalance charges, this will result in other shippers paying more).

In light of these points, the Transporter considers the conventional approach to calculating the Imbalance Gas

Transportation Cost to be appropriate as it references the NBP to Moffat benchmark transportation costs in all instances.

12. Balancing

Activities to be Completed

Issues requiring industry/GNI/CER agreement:

• Finalise contractual arrangements with Preferred Tenderer.

• Finalise Business Rules for TP activity, reflecting industry feedback.

• Information Provision

‒ Publication of data on system linepack.

• Other Activities

‒ Finalisation of IT systemisation change requirements.

‒ Business process amendments (e.g. Grid Control operations, validation of bal.

actions, invoicing/settlement).

Note: Any currency conversion for agreed trade prices on the TP (e.g. from GBP

sterling to Euros) is to be completed at the billing stage, i.e. trade prices are to be

entered on GTMS as per the original currency denoted on the TP.

‒ Code Modifications to reflect new regime.

‒ Internal Work Instructions and GNI Grid Control training.

‒ Bilateral contracts with counterparties to enable trading with them on TP.38

Activities Completed to date

• Balancing Arrangements Consultation completed.

• Initial Draft of Business Rules circulated and industry feedback collated.

• Tender for TP services issued, and submissions received and evaluated.

• Complete and award tender

• Scoping of IT systemisation

and process change

requirements

Summary of Activities Completed/ to be Completed (Phase 1)

Activities to be Completed

Issues requiring industry/GNI/CER agreement:

• Establish sections of the Code possibly requiring amendments.

‒ Further review tolerances and proposed cash-out pricing regime once TSO participates on a live and liquid TP.

39

Activities Completed to date

• Initial review of tolerances and cash-out regime completed.

‒ Proposed imbalance CO prices to apply once the

TSO participates on a liquid TP, and TSO’s

interpretation of the relevant sections of the

Regulation concerning tolerances.

Summary of Activities Completed/ to be Completed (Phase 2)

Transporter wishes to reiterate its standpoints that:

1. It considers any decision on potential amendments to tolerances and imbalance cash-out prices to be premature, ahead of

an agreed benchmark of proven liquidity on an IBP TP.

2. The shipping community should be mindful that any potential amendments to tolerances will have an impact on both the

level of flexibility provided by a tiered tolerance regime and the Disbursements Account.

13. VRF Tariffing Structure

• Following the VRF presentation made by ESB at the July CMF Meeting, one industry response was received.

IOOA Response to ESB VRF Tariffing Proposals

• IOOA members wish to state that they agree with the Regulator that

‒ Any change to VRF tariffing must be consulted upon by the Regulator, and

‒ The Regulator should focus its efforts on determining the form of an enduring VRF tariff necessary to meet with the Tariff NCRequirements in October 2019.

• IOOA members disagree with the ESB’s assertion that forward flow shippers are cross subsidising VRF shippers.

‒ IOOA believes that its members are paying the incremental cost of providing the service, in addition to the shrinkage charge.

‒ IOOA notes the views expressed throughout Europe during the Tariff NC consultation process about VRF services saving shippersmoney by reducing fuel gas consumed, and having the potential to reduce variable and perhaps fixed costs.

• IOOA considers the options proposed by ESB to be ad hoc and not to reflect the current incremental cost approach to tariffing.

• IOOA believes that the ESB’s comment that Irish consumers are only realising partial benefits of indigenous supply to be incorrect.

‒ IOOA notes that between Nov 2016 and June 2017 inclusive, 93% of total Irish indigenous supply has been consumed in Ireland (only 7% has been exported).

‒ IOOA also states that, in the context of the ESB’s comment which suggests that all indigenous gas should be the sole benefit of Irish consumers, the Tariff NC specifically sets out the objectives of contributing to market integration, enhancing securing of supply and promoting the interconnection between gas networks.

15. BrExit and ROI Gas Market

Brexit and ROI Gas Market (Slide 1/3)

• Main Brexit related activity with regard to Energy was with the publication of a UK position paper entitled

‘Northern Ireland and Ireland’ on 16th August.

• This paper also dealt with energy. It details the importance of continued cooperation with regards to SEM, but

also outlines the important of the ‘continued ability to trade gas between GB and the island of Ireland for

security of supply and efficient market operation’.

• Additionally, the paper outlines that ‘there should be a strong shared desire between the UK government, Irish

Government and the rest of the EU to support the stability of energy supply on the island of Ireland, and

maintaining affordable, sustainable and secure electricity supplies’.

45

https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/638135/6.3703_DEXEU_Northern_Ireland_and_Ireland_INTERACTIVE.pdf


The document proposes that the new framework relevant to the energy market in Northern Ireland and Ireland should:

• take account of the strategic importance placed on cross-border cooperation in the Belfast Agreement, which provides for cooperation between Northern Ireland and Ireland, and the UK and Ireland.

• facilitate the continuation of a single electricity market covering Northern Ireland and Ireland.

• facilitate the continuation of efficient electricity and gas interconnection between the island of Ireland and Great Britain.

• providing certainty on energy arrangements and,

• include an appropriate interim period to ensure any changes to current arrangements can be implemented in a timely way.

46


• GNI is due to meet with National Grid in September, with a view to commencing initial discussions regarding day-to-

day interaction and operations at Moffat post Brexit.

• If there are any specific issues/concerns you would like us to raise, please contact us.

Business Processes for Renewable Gas Projects

Business Process Approach for Renewable Gas Injection

• Regulatory Jurisdiction

‒ The Entry Points will be given a Renewable Gas Classification, but most processes will reflect current Code of Operations arrangements.

The Connected System Operator (CSO) will be a party to a Connected Systems Agreement (CSA) and the Shipper will be bound by the Code of Operations via the Framework Agreement. The CSA will oblige the CSO to comply with the Code of Operations.


• Registration of Shipper – At least one Shipper must be registered at the Entry Point

• Capacity

‒ No facility to Transfer Entry Point Capacity is proposed (due to designation as Renewable Gas Entry Points)

‒ Otherwise, the same suite of annual, quarterly, monthly and daily products will apply at this entry point as at other entry points. The Shipper will book capacity as per the process employed at other entry points.

‒ CER regulated tariffs will apply at the entry points.

• Nominations

‒ The CSO will notify the Shipper no later than D-1 as to the amount of gas to be injected into the system.

The CSO & Shipper must agree communications protocol and frequency ahead of Day.

‒ The Shipper will “nominate” this amount on D-1, reflecting the CSOs notified data.

‒ The CSO will notify the Shipper of any within day amendments to forecasted flows and End of Day Quantities (EODQ).

‒ The Shipper will “Re-nominate” this amount on D, reflecting the CSO’s notified data. The process will apply every day.


• Allocations

‒ Allocations at Entry Points will be made in accordance with current procedures

‒ An allocation agent will not be required. Gas will be allocated as per data from the Entry Point meter. The allocations will be divided out on a pro-rata basis to each Shipper (based on Shipper nominations).

• Flow Profile

‒ Nomination flow profiles will not be required initially, however this may be required at a later date should quantities of renewable gas and / or the number of entry points increase sufficiently.

• Balancing

‒ Balancing arrangements will be in accordance with current procedures.

‒ An Operational Balancing Account (OBA) will not be required.


• Measurement‒ The Connected Systems Agreement (CSA) will define the measurement equipment and procedural

obligations of the CSO, including obligations to facilitate GNI’s access to validation, calibration and maintenance processes.

• Data Cleansing‒ There may be a requirement to adjust the monthly meter data in the event of a correction for data

loss, or amendment following a calibration test.

• Capacity Overrun‒ The overrun arrangements will be in accordance with current procedures.

• Tolerance‒ The Entry Tolerance should be appropriate to the scale of production at the Renewable Gas Entry

Point. 1.5% is stated in the Code. This will be relaxed to an agreed % during the commissioning phase.

GNI is minded to propose further relaxation of tolerance subject to operational experience.

Proposed Connections Policy and Tariffs for Renewable Gas

Proposed Renewable Gas Connection Policy

• Gas Networks Ireland has developed a connections policy proposal.

• The connections policy proposal has been drafted taking into account the responses that are outlined in the Renewable Gas Bridging paper and the feedback that Gas Networks Ireland received after the industry meeting that was held in February.

• Gas Networks Ireland is proposing that there would be an economic test which should result in a positive Net Present Value (NPV).

• If the economic test results in a negative NPV then a supplementary charge will apply.

• A public consultation on the connections policy proposal is likely to open early in September and run for 4-6 weeks.

Renewable Gas Tariffs

• Gas Networks Ireland is currently working on a proposal for a Renewable Gas Entry Point tariff.

• As the first renewable gas injection facility is a demonstration project, Gas Networks Ireland is proposing that an interim tariff be applied for this Renewable Gas Entry Point.

• An enduring tariff for Renewable Gas Entry Points will subsequently be developed.

Pending Code Modification proposal for Renewable Gas

Part A – New definitions (main changes)

• "Renewable Natural Gas" or "RNG" means sustainably processed gas derived from non-fossil sources which meets the Natural Gas Specification as outlined in Part G (Technical) Appendix 1 in the Code of Operations

• "RNG CSA" means an agreement of any description entered into by the Transporter and the Connected System Operator of a RNG Facility regulating, inter alia, the physical and operational interconnection between the Transportation System and the RNG Facility.

• "RNG Delivery Facility" means the plant and equipment constructed and/or installed at the RNG Delivery Site which is connected to the RNG Entry Point.

• “RNG Entry Point” means an Entry Point which is connected at the Connected System Point to a RNG Delivery Facility

• "Entry Capacity“ means capacity at an Entry Point to the Transmission System or at an RNG Entry Point …".

• Minor amendments are required to other existing definitions to include for RNG

Part D (Nominations and Allocations)

• Amend Section 2.5.1 by adding the following:

• ["If there is an Allocable Quantity at an Entry Point for a Day on which there are no Shipper's Entry Nomination(s) at that Entry Point for that Day, the Allocable Quantity shall be allocated among all Shippers which are Registered Shippers at the Entry Point on that Day.]

• Part D Section 2.7.3(v), Formula will be revised as follows

• NDM = (CC + RNG) – (DS + LDM + DM)

RNG = the quantity of Natural Gas (in kWh) metered at an RNG Entry Point downstream of the CitygateMeter.

Part E (Balancing and Shrinkage)

• RNG would be treated as an Entry Allocation so no changes required to Disbursement Account

• No change required to Daily Imbalance Calculation

• In Section 1.7.2 amend table to include RNG Entry with an agreed tolerance

• In Section 1.7.4 amend the formula by adding agreed tolerance for RNG

• In the legend to Section 1.7.4 include "RNG means the Final Entry Allocation at each RNG Entry Point for a Shipper".

Part G (Technical)

• Renewable gas contains relatively more oxygen than Natural Gas (can be up to 1% mol O2). GNI are currently reviewing the current upper limit for oxygen content in the Natural Gas Specification (0.2% mol)

‒ In 2013 the UK HSE issued a Class Exemption that permits oxygen mole fraction up to 1 % for gases conveyed below 38 bar, provided that such gases are compliant with all other requirements of the Gas Safety Management Regulations.

‒ Following a Measurement Risk Assessment of the Renewable Gas to Grid project, GNI were recommended to explore the option of increasing the upper limit value for oxygen from its current limit of 0.2%

‒ GNI are currently in the process of commissioning a study on assessing the impact of increasing the upper limit of oxygen content in both the distribution and transmission networks.

Decarbonising Transport -Opportunity for gas

Decarbonising Transport - Opportunity for gas

• Transport sector one of the most difficult to decarbonise

‒ Liquid hydrocarbons are an ideal transport fuel

• NTA running market consultation on options for decarbonising public bus fleets

‒ See BusConnects project

‒ 1000 buses in Dublin alone to be converted to Low carbon bus technology

• Bio-methane /CNG buses are a well tried and tested technology

‒ Including in Ireland

‒ Successful trial in Cork 2012 proved the concept

• gas current market share in Ireland

‒ C. 55% of power gen market

‒ C. 35% of heating market

‒ C. 0 % of transport market

• 42% of energy consumed in Ireland is in transport sector

‒ This is a huge opportunity for gas 73

Natural gas /biogas Public bus fleet opportunities

Dublin Bus and BusConnects project

• NTA published the BusConnects project policy document on 29th May 2017 in conjunction with DTTaS.

• This policy document outlines the objective to convert the Dublin Bus fleet of 1000 buses to green bus technology.

• 1000 buses on CNG /biogas would add demand of annual demand of c. 400GWh per annum (based on Bus Eireann trial in Cork data).
