2 2 Agenda  Overall aims  Overview and key assumptions  Analysis:  Scenarios  Potential impact of EU Framework Guidelines on GB Charging – December 2013 Scenarios (for reference)  Potential impact of EU Framework Guidelines on GB Charging – New Scenarios Analysis  Summary

3 3 Overall Aim (1)  Give potential impacts the Draft EU Tariff Code on the GB NTS Charging Arrangements  Help industry understand potential impacts of the EU Draft Tariff Code on GB NTS charging that may help inform any responses to the code consultation  To support Ofgem’s Gas Transmission Charging Review (GTCR) and the technical modelling workshops scheduled over the Summer

4 4 Overall Aim (2)  Considered two approaches  Minimal approach – just on Interconnection Points (CAM Points)  Impact on all of domestic entry and exit points (CAM and non-CAM Points)  Analysis provides indicative impacts – does not provide any forecasts  The options presented here are indicative and are not how we propose or suggest the Framework Guidelines be implemented

5 5 Overview: Summary of data used in Analysis  Analysis used formula year 2012/13 to look at what the potential impacts would have been if we applied the EU Tariff Code at:  Interconnection Points only (CAM Points);  All Entry and Exit points of GB (CAM and non-CAM Points)  Assumed no changes in bookings / behaviour / flows  Uses a number of assumptions due to uncertainties or areas that need consideration  Looks at the revenues that would be need recovered under the scenarios and how they might be recovered

6 6 Overview: Key Assumptions (1)  What we mean by implementing the EU Draft Tariff Code:  Where used, the commodity charge as per the EU Draft Tariff Code is to recover the cost to flow gas  We have used costs for shrinkage as a proxy for fuel costs  Cost Allocation Methodology for the charging regime for the calculation of charges using the LRMC methodology (“Virtual point variant A” in EU Draft Tariff Code) remains  Any targeted charges (linking to “Dedicated Services”) or specific charging arrangements (e.g. current arrangements for storage) assumed to remain in place

7 7 Overview: Key Assumptions (2)  Charges set to aim to recover the target allowed revenue for the year including a mechanism to recover any shortfall  When considering how revenue shortfalls could to be recovered in the different scenarios this could be:  Through a mix of capacity and commodity; and  Potentially recovered in either a uniform method across all GB points or via a dual methodology for CAM and non-CAM points

12 12 Scenario 1 (Dec 2013 analysis) Overview: Apply EU FGs at CAM Points only  TO Revenues / charges  Allowed revenues unchanged  Same charging methodology for capacity as now  No changes to Capacity charges / revenues  EU FG Commodity charge (shrinkage) for all  Commodity charges recover shortfall  Apply to domestic only (Non-CAM Points) as exclude IPs (CAM Points) under EU FGs  Therefore use a smaller charging base to recover commodity  Targeted charges / pass through items remain as is

13 13 Entry Capacity (All) Scenario 1 – Implementing EU FGs at IPs (CAM Points) only DN Pensions Deficit & NTS Metering TO Charges Exit Commodity (Non-CAM only) Exit Flat Capacity (All) Entry Commodity (Non-CAM only) SO Charges St Fergus Compression + Shorthaul + Legacy Incremental Entry/Exit* + Neutrality Entry Commodity (Non-CAM) Exit Commodity (Non-CAM) Commodity (All)

14 14 Scenario 1: TO Analysis (Entry and Exit Commodity) /13 16% Increase 5% Increase

15 15 Scenario 1: SO Commodity Analysis – Entry and Exit 2012/13 10% Increase 70% Decrease

16 16 Scenario 2 (Dec 2013 analysis) Assumptions: Apply EU FGs across all GB  Total allowed revenues unchanged (combined TO+SO)  SO Commodity charge only recovers shrinkage  Apply to all points with any under recovery on what we have as remaining SO Commodity would move onto TO Capacity charges  Same charging methodology for capacity as now  Capacity charges (Entry and Exit) would need to be adjusted on top of those calculated using the Transportation Model to collect allowed revenue (TO+SO)  There are a number of options that could be applied to achieve this  Targeted charges / pass through items remain as is

17 17 Scenario 2 – Implementing EU FGs Charges (FG) – Step 1 DN Pensions Deficit & NTS Metering Entry Capacity (All) Entry Commodity (All) Exit Commodity (All) Exit Flat Capacity (All) Entry SO Shortfall (All) Exit SO Shortfall (All) Charges (FG) – Step 2 DN Pensions Deficit & NTS Metering Entry Capacity (All) Exit Flat Capacity (All) Entry Shortfall (All) Exit Shortfall (All) Recalculation of Exit Capacity Charges

19 Place your chosen image here. The four corners must just cover the arrow tips. For covers, the three pictures should be the same size and in a straight line. Action NTS0507: Potential impact of EU Draft Tariff Code (DTC) on GB Charging – New Scenarios

20 20 Overview – New Scenarios  The following scenarios follow on from the analysis done in December 2013  Analysis used formula year 2012/13 to look at what the potential impacts would have been if we applied the EU Draft Tariff Code  Assumed no changes in bookings / behaviour / flows  Uses a number of assumptions due to uncertainties or areas that need consideration  All key assumptions within the December 2013 analysis are applicable to this analysis

21 21 Scenario 3 – Apply EU DTC at all points with TO and SO split  Total allowed revenues unchanged (combined TO+SO)  SO Commodity charge only recovers shrinkage  Apply to all points with any under recovery on what we have as remaining SO Commodity would move onto TO charges  Capacity Floating and Floating Regime (split by TO and SO)  Targeted charges / pass through items remain as is

22 22 Scenario 3 – Apply EU DTC at all points with TO and SO split SO Charges St Fergus Compression + Shorthaul + Legacy Incremental Entry/Exit* + Neutrality Entry Commodity (All) Exit Commodity (All) Entry Capacity (All) DN Pensions Deficit & NTS Metering Exit TO and SO Shortfall Exit Flat Capacity (All) Entry TO and SO Shortfall TO Charges

23 23 Scenario 3 – Apply EU DTC at all points with TO and SO split £190m £50m £340m

24 24 Scenario 4 - Apply EU DTC at all points with CAM and Non-CAM split  Revenue Amount - Values based on model and what is allocated to IPs (CAM Points) and non IPs (Non CAM Points)  New Capacity Rates at both IP’s (CAM Points) and Non IPs (Non- CAM Points)  Total Revenue split by CAM and Non-CAM points  Commodity charge only recovers shrinkage  Revenue not collected would need to be collected from Capacity  Floating Regime (CAM and Non-CAM split)  Targeted charges / pass through items remain as is

25 25 Scenario 4 - Apply EU DTC at all points with CAM and Non-CAM split CAM Commodity Non-CAM Commodity CAM Capacity (All) DN Pensions Deficit & NTS Metering Non-CAM Shortfall Non-CAM Capacity (All) CAM Shortfall St Fergus Compression + Shorthaul + Legacy Incremental Entry/Exit* + Neutrality

26 26 Scenario 4 - Apply EU DTC at all points with CAM and Non-CAM split £195m £44m £6m £30m £44m £145m £6m £17m

27 27 Scenario 5 – Apply EU DTC at all points (mix of Capacity/Commodity)  Fixed regime is today for IP’s (CAM Points) and Non- IP’s (Non-CAM Points)  Remove Shrinkage Revenue from the SO Commodity Revenue  The shortfall in SO Commodity Revenue needs to be collected by an alternative Commodity Charge  The TO Commodity Revenue needs to be collected by an alternative Commodity Charge

28 28 Scenario 5 – Apply EU DTC at all points (mix of Capacity/Commodity) SO Charges St Fergus Compression + Shorthaul + Legacy Incremental Entry/Exit* + Neutrality SO Entry Alternative Commodity SO Exit Alternative Commodity Commodity (All) Entry Capacity (All) DN Pensions Deficit & NTS Metering TO Exit Alternative Commodity Exit Flat Capacity (All) TO Entry Alternative Commodity TO Charges

29 29 Scenario 5 – Apply EU DTC at all points (mix of Capacity/Commodity) £220m £120m £45m £145m

30 30 Summary (1)  Where considering floating charges, capacity charges could be subject to an additional adjustment to aim to recover target allowed revenues for the year (e.g. on top of any existing adjustments)  Could include revenue uplift (like Exit), inflation adjustments or other  Options include taking revenue shortfall recovering based upon:  Adjusting using baselines or obligated levels  Adjusting using forecast bookings  Issues to consider would be:  Application of any uplift considering (amongst other items):  The methodology to be applied in the Transportation Model  The application of discounts for short term capacity  How to apportion any uplift or adjustment

31 31 Summary (2)  EU Draft Tariff Code gives some flexibility in the adoption of fixed or floating tariffs  Becomes a GB discussion about optimal balance between charges and points to recover revenue  Ofgem’s GTCR and modelling workshops will be looking at this in some detail and there will be assumptions within this work on the EU Draft Tariff Code
