Why a Supply Chain Approach to Gas Security? � Provides a necessary anXdote to the current failings of
the literature on the geopoliXcs of energy security vis-‐à-‐vis natural gas.
� Provides a framework for analysis of the different dimensions of gas security.
� Provides a framework for idenXfying the actors, relaXonships and networks that influence global gas security.
� Provides a basis for examining the interacXons between global trends and regional (EU) and naXonal (UK) energy policies.

UK gas production peaked in 2000 and has since been declining. With declining production the UK has become increasingly reliant on gas imports to meet demand. Since 2000 net imports have steadily increased year on year, with the exception of 2011 which saw a 3 per cent decrease on the previous year’s level. The recent fall in imports can be attributed to the reduced gas demand from electricity generators.
Imports of Liquefied Natural Gas (LNG) through the two terminals at Milford Haven (South Hook and Dragon) and via the Isle of Grain remain substantial, but their shares of total imports have dropped from 46 per cent in 2011 to 27 per cent in 2012. Demand for LNG on the global market remains strong but the UK has a diverse pipeline infrastructure (from Norway, the Netherland and Belgium) and the proportion delivered through each route will depend on global market conditions.

2.5.1 Supply Overview National Grid’s UK Future Energy Scenarios publication examines the gas supply components behind the two scenarios – Slow Progression and Gone Green. Rather than replicate this information, the supply section of the 2013 Ten Year Statement contains the information related to Gas Transmission capability planning:
■ Charts showing annual and peak supplies for the two scenarios;
■ Chapter 3 also details some background on the historic changes of gas supply; including historical evidence on the winter variation between winter maximum and minimum;
We have highlighted in recent years how supply patterns on the NTS are changing and are anticipated to become more uncertain into the future. Figure 2.5A represents some of the changes we have seen in flows on the system from the mid 1990’s to today.

Na*onal Grid’s Annual Gas Demand Scenarios 2013
025
Our Slow Progression scenario has a fairly flat view of annual demand over the scenario period. There is a further decrease in demand from 2012 due to a slower economy. Total demand then remains broadly flat, until the mid 2020s when total demand starts to decrease predominantly due to the changes in power generation demand.
Figure 2.2A Annual Gas Demand Scenarios including history – Slow ProgressionSource: National Grid
Figure 2.2B Annual Gas Demand Scenarios including history – Gone GreenSource: National Grid
In the Gone Green scenario, there is a continual reduction in annual gas demand throughout the scenario period. This is due to a combined influence of further efficiency savings, a transition to alternative sources of energy in our Gone Green scenario, and power generation being maintained as marginal plant for electricity balancing and reserve.

Conclusions � There is a tendency to focus on the issue of physical security of
supply—the UK has a diverse gas supply system—but it is increasingly exposed to risks in global gas markets and price security of supply is the more likely concern.
� Most supply disrupXons have been technical failures in the upstream and midstream, but miXgaXon measures—interconnecXon and storage—can reduce these risks, but who pays?
� The greatest source of insecurity and uncertainty relates to ‘security of demand’ and this is impacXng on investment in the power generaXon sector.
� How much gas, for how long requires an whole systems approach.
