Cush RNG Injection Project Code Modification Forum Update 13 June 2018

Agenda  Biomethane Potential in Ireland  The Cush RNG Injection Project  Production site  Injection site  Legal, Safety, Regulatory & Market Development  Next Steps 17

Biomethane Potential in Ireland

Policy Background • Ireland’s renewable energy sources (RES) target is 16% RES by 2020. • Ireland’s Greenhouse Gas (GHG) emissions target is 20% less CO 2 by 2020 relative to 2005. • Road and rail transport contributes ~ 29% of non-ETS GHG emissions. Fig.1 EPA non-ETS GHG emissions forecast for 2020 • Agriculture contributes ~ 46% non-ETS GHG emissions. • Ireland is set to miss both RES and GHG 2020 targets. 19

Renewable Gas Potential in Ireland • “The Member States with the largest potential growth of biogas production between 2014 and 2030 are Ireland and Romania”, (European Commission Report 1 ). 1 Kampman et al. 2016. “Optimal use of biogas from waste streams; An assessment of the potential of biogas from digestion in the EU bey ond 2020”. Available at: https://ec.europa.eu/energy/sites/ener/files/documents/ce_delft_3g84_biogas_beyond_2020_final_report.pdf 20

Biogas Potential in Ireland • Assessment of Costs and Benefits of Biogas and Biomethane;  28% of 2015 natural gas demand can be supplied from biogas.  Additional grass is the largest bio-resource in Ireland (35 PJ).  Levelised Cost Of Energy (LCOE) biomethane range ( € 24 - € 124/MWh) depending on feedstock, scale and discount rate. 21 SEAI, 2017. “Assessment of Costs and Benefits of Biogas and Biomethane”. Available at: https://www.seai.ie/resources/publications/Assessment-of-Cost-and-Benefits-of-Biogas-and-Biomethane-in-Ireland.pdf

Gas Networks Ireland’s Vision for Renewable Gas  Reduce carbon footprint of network through development of Renewable Gas.  20% renewable gas on network by 2030.  20% renewable gas will deliver;  2 million tonnes less CO 2 p.a.  7.4% of Ireland’s Final Energy Consumption.  € 200 million euro p.a. avoided energy imports.

Cush RNG Injection Project

Gas to Grid Project Process Overview Biogas Quality Biogas Biogas Pre- Monitoring Production treatment Location: Existing Pressure Meets Biogas Quality AD facility at Requirements? Reduction Station Gorteen Lower, No Nurney, Co. Biomethane Kildare Yes Flare Biogas Upgrading Process No Biomethane Yes Natural Gas Meets Natural Gas Network Entry Distribution Quality Specification? Yes Facility Network Meets Biogas Quality Requirements? Biomethane Compressor & No Location: Cush Biomethane Network 24 Dispenser Entry Facility

Production Site

Biomethane Production • AD Site; Green Generation, Nurney, Co. Kildare ‒ EPA licence to take in 25,000 t/annum of biodegradable waste plus 25,000 t/annum of pig slurry from farm • Biogas Pre-treatment Process ‒ O 2 dosing control system ‒ Additional activated carbon to control VOCs • Biogas Upgrading Process ‒ Oxygen < 1% ‒ Moisture – 60 0 C at 4 bar ‒ Methane concentration > 98% • Compressor Station & Disperser • Transportation Trailers - ADR compliant 26

Injection Site

Cush Injection Site • The Network Entry Facility will contain;  Propane Injection System  Non-Fiscal & Fiscal Flow Meters  Pressure & Temperature Sensors  Gas Analysers (C6 GC + sensors)  Diverter Valves  Pressure Regulators 28  Odorant Injection System

Biomethane Network Entry Facility GNI will own the following assets;  Remote Operated Valve.  Remote Telemetry Unit.  Connecting pipe to the network Delivery Facility Operator will own and operate other assets within the Biomethane Network Entry Facility Image curtesy of Thyson Technology UK 29

Legal, Safety, Regulatory and Market Development

Key GNI Deliverables  Contracts  Safety  Connected Systems Agreement  Measurement Risk Assessment  Connection Agreement  Safety Integrity Level Assessment  Property Arrangements  Layer of Protection Analysis  Code of Operations Modifications  Impact Evaluation & Risk Assessment  General  Material Change Notice  Oxygen Content  Technical Specification Document  Tariffs  Local Operating Procedures  Interim  Communications Plan  Enduring  Deployment & Commissioning Plan  Staff Training  Systemisation 31

Key GNI Deliverables cont’d  Code Modification Proposal A091: Modification of oxygen content limit for biomethane  Proposal:  Increase the current oxygen limit of ≤ 0.2mol% to ≤ 1mol%  Applicable to biomethane entry points and to exit points only  All other gas specification parameters will apply at these points  Relevant entry points will be subject to continuous monitoring of both dew point and oxygen content  Rationale:  Some biomethane sources will not be able to meet the current oxygen limit  Benefits  Modification will enable biomethane producers to meet GNI’s quality specifications  Biomethane production is to be encouraged as it supports, inter alia, the reduction of carbon footprint of the gas network and the reduction of carbon emissions, thereby helping to future proof the gas network in Ireland 32
