Potential crunch coming for UK gas supplies - Ofgem CEO

We're tweeting and blogging
this year's Economist Energy Summit.
Why is the government focusing so much on gas? The Chancellor in
his Budget speech earlier this year said gas is cheap,
and DECC recently
introduced new measures allowing existing gas plant to carry on
emitting at current level for the next few decades. Is this a
particularly good idea?
According to the CEO of the independent energy regulator Ofgem,
Alistair Buchanan, the answer is no. But unless the current
situation changes, he said today, a new push for gas is
The government's current pursuit of a gas generation strategy is
down to a combination of factors, Buchanan said at the
Economist Energy Summit today. First and foremost,
the need to meet carbon targets by cutting back on coal power is
driving interest in natural gas, which is lower carbon, if not
Alternatives to coal like nuclear and offshore wind aren't coming
on-stream as quickly enough to replace generating capacity -
offshore wind, for example, isn't yet producing enough electricity,
Changes in Europe are also meaning that gas is becoming more
popular - demand for gas in Europe was already growing, and has
risen by up to 150 billion cubic metres (bcm) due to the decision
by Germany and others to eventually abandon nuclear power
But on the supply side, things aren't looking great for the UK.
The National Grid conducted a study in January 2011 - an unusually
mild month - to see how the gas supply would react to shocks such
as the closing of the Suez Canal or an international increase in
demand for gas imports. If anything like that had happened during
that very comfortable winter, consumers would have faced gas supply
interruptions, Buchanan said.
And it could get worse, he argued. The UK can currently store
about 4 bcms of gas - but we use around 100 bcms per year, and UK
storage was at historic lows in January 2011.
Securing future supplies could also be difficult, he argued. Key
gas fields expected to come online in Russia and neighbouring
countries have been delayed, as have pipelines that could bring gas
from the Arctic or middle Asia.
What about shale gas from the EU? Buchanan said that's not looking
great either, due in no small part due to strict EU environmental
regulations governing water and chemicals. There's also the small
issue of public opinion and government will - there won't be any
US-style tax breaks to support the US shale gas industry in the
According to Buchanan's presentation, at the moment it looks like
there's going to be a squeeze on gas demand between 2015 and 2020
while the world waits for new gas supply nations to come online.
This is at exactly the same time as the UK demand for gas will be
going up due to coal decommissioning and the leisurely pace of new
technologies coming online, raising fears of a crunch in gas
The UK's largest three political parties agree the UK's energy
mix should be low carbon renewables and nuclear, he argued. But
whatever the ambitions, the slow pace of low carbon and nuclear
development is leaving the focus on gas, almost by default.
