Midstream gas assets are coming back into focus after a lull across the first half of this decade. A 20% decline in European gas demand between 2010 and 2015, caused a pronounced erosion of midstream asset utilisation and capacity value. But the sands are shifting as European gas supply dynamics change and demand continues to recover.
Midstream asset transaction momentum is starting to build again. Last year saw EPH sell a 30% stake in its key Slovakian transit pipeline & storage business, with Global Infrastructure Partners selling its 45% stake in the Transitgas pipeline into Italy. EDF, Uniper & Edison are currently in the process of selling equity stakes in French and Italian regas terminals. The gas storage market is also coming to life, particularly in the UK given the permanent closure of Rough.
In the more than 20 years we have been working in European energy markets we cannot remember a time of greater divergence in views on gas market evolution. This lack of consensus on supply mix, flow patterns, midstream asset utilisation and capacity value is an environment of opportunity for investors. But how do you think about midstream asset value?
Europe in a state of transition
The key force acting on the supply side of the European gas market is rising import dependency. This is reflected in increasing Russian import volumes in 2016-17, accompanied by an ongoing shift in flow patterns as Gazprom favours the Nordstream (Baltic) routing over Ukraine. European LNG imports and regas terminal utilisation have also risen to their highest level in five years.
The fact that Russian and LNG imports are rising together reflects growth in European gas demand, with a 27 bcma (5.4%) increase in 2016. 20 bcma of this was driven by higher power sector demand as coal plants were switched for CCGTs. The evidence so far in 2017 points to a continuation of that trend.
Even the substantial overhang of gas supply flexibility is starting to abate. Centrica Storage has now announced permanent closure of its large UK Rough storage facility (more than 70% of UK working gas volume). Further storage closures and capacity reductions are looming on the Continent. And European upstream flexibility is declining as field production matures (particularly given rapidly lowered volumes from the Dutch Groningen field).
Midstream infrastructure map
A map is a good place to start when considering the impact of this European gas market transition on midstream gas infrastructure. Diagram 1 shows the key supply routes into the main European market hubs. Volumes of storage capacity and LNG regas terminal capacity are also shown.
