The PCIs envisage the development of alternative sources of supply and supply routes to
Ireland [23]. The Shannon Liquefied Natural Gas (LNG) import terminal, which was granted
planning permission in 2008, is listed on the EU PCIs. While construction for this project
has yet to begin, it would allow Ireland to import gas from the Atlantic Basin (incl. US) and
Middle East, thus bypassing the UK and providing Ireland with diversified gas supplies. The
development of the Islandmagee Underground Gas Storage (UGS) facility in Northern Ireland,
which is expected by 2021, would further improve the security of supply and the flexibility of the
gas market in Ireland. However, their implications for consumers are not addressed. Developing
a LNG import terminal would provide access to the increasingly competitive international gas
market, making the Irish gas market more competitive. The development of a storage facility
would allow the management of seasonal loads, thus reducing gas price volatility and the risks
of supply shortage. In the following section, we investigate what is the optimal and most competitive option for Irish consumers in 2025, i.e. when the Corrib field is expected to be
depleted and when LNG and storage facilities should be operational.
That is, the Irish storage facility allows for higher volumes of gas to be
imported into Ireland during the summer, when gas prices are lower compared to winter. These
volumes mostly come to Ireland through the UK. During winter, i.e. when gas demand is higher,
the storage facility allows the gas to flow back to the UK via the Moffat pipeline. Therefore, an
Irish storage facility would enable arbitrage opportunities in the gas markets to be exploited by
allowing the gas to be imported (and stored) into Ireland from the UK in the summer at lower
costs, and to be reexported to the UK in the winter, at higher costs.
Overall, evidence in Figure 9 implies that an Irish storage facility would reduce total expected
consumer costs
By investigating the impact of gas infrastructure outages on power systems, [45] argue that
lack of gas storage capacity in Ireland increases the risk profile of electricity generation, and in
turn generation costs. They estimate that a storage facility in Ireland can reduce generation
costs up to 40%. Potential under-investment in natural gas infrastructures can influence power
sector functioning in Ireland, especially when considering the high penetration of wind power.
