Problem with gas imports at Bacton Interconnector?!?!

OK, this is a bit scary - I just finished writing my previous post, and then went to the National Grid web page that shows live data about gas flow, and was alarmed to see this graph:

Gas flows at Bacton Terminal 7:20am 22 Mar 2013

What it shows is imports from the Bacton Interconnector falling from nearly 80 million cubic meters (mcm) per day down to zero. To put this in perspective, UK demand today is expected to be about 327 mcm, so that's a quarter of today's gas supply gone missing.

No new response at the time of writing from storage sites, and nothing in the news yet... Let's hope they get it back online soon, or we really may have a problem right now...

UPDATE: the mainstream media has caught up with me:
Britain's wholesale gas prices surged to a record high on Friday, after one of its three gas import pipelines shut down unexpectedly.

The operator of the UK-Belgium Interconnector pipeline said a technical problem had forced the shutdown, without giving more details.

If the pipeline remains shut for a number of days, Britain's grid operator will be forced to trigger all emergency supply options, including reducing demand from contracted users, which will cause an even higher price spike, traders said. source

The media wakes up to the current energy shortage

Today Reuters and the BBC realised we don't have much gas left in UK storage. I've been blogging about this on and off for some years now, and in particular over the past month or so, and finally it's deemed important enough to be in the news.

Britain is grappling with a potential gas supply crisis as a late blast of winter depletes stored reserves, coal power plants close and pending maintenance in Norway threatens to further squeeze supply.

The country risks running out of stored gas by April 8 based on the fall in its reserves seen since the cold hit at the beginning of March, Reuters calculations show.

Gas storage sites have been depleted by 90 percent, with the equivalent of less than two days' consumption remaining, data from Gas Infrastructure Europe shows.

If the cold persists, as is forecast, the UK may need to cut gas supplies to some big industrial customers, as it did in 2010 at a time of severe gas shortages. source
The BBC starts with a message from SSE about the impending electricity crunch, and mentions the gas issue later on:
The boss of the energy firm SSE has warned that "there is a very real risk of the lights going out" in Britain.

Ian Marchant said the government was significantly underestimating the scale of the capacity crunch facing the country.

He was commenting on the company's decision to cut back on power generation at five sites.

The energy regulator, Ofgem, has also warned of an increased risk of a blackout.

In February it predicted power station closures could mean a 10% fall in capacity by April alone.

SSE points out that the regulator did not take into account its plans to cut power generation when the warning was issued and that therefore, makes the warning even more stark.
...
SSE is reducing its energy generation by 2,000MW over the next year. The power stations affected are Ferrybridge, Keadby, Slough, Uskmouth and Peterhead. It is also postponing further investment in gas-fired electricity generation until at least 2015. source
Just to make matters worse, the current cold snap comes just as Didcot A coal power station shuts down - it will stop generating at 2pm today,  so that's 2,000 MW of capacity which will need to be replaced by gas from this afternoon.

Don't forget you can keep an eye on the current gas supply situation on the National Grid website. The next few days are forecast to be very cold - more news to follow as it happens...

What does the future hold for UK gas supply?

The gas crunch in the UK continues, with the current cold weather pushing demand up and very low storage continuing to be a concern. An article yesterday in the FT explains the situation very well (note, you can go via Google to avoid the paywall):

When a power cut at the Nyhamna gas processing plant in Norway hit production this month, prices in the UK soared 50 per cent in one day. The plant feeds the 1,200km Langeled pipeline that exports gas from the vast Ormen Lange field to Britain.

The loss in output was shortlived but for many in the UK it was indicative of a more worrying trend: an increasing exposure to new supply risks as North Sea production declines and competition for imports of liquefied natural gas increases.

Coming at a time when ageing coal-fired plants are being retired and new nuclear power faces delays, it raises questions over energy security, as the industry undergoes its biggest changes since privatisation in the 1980s. Alistair Buchanan, chief executive of Ofgem, the electricity regulator, warned of higher energy bills last month ahead of a “horrendous” gas supply crunch.
These are all issues I've written about recently on this blog, here and here. Just to summarise, these are the key problems that affect the UK at present or in the near future:
  • Gas production from our own fields is falling, often by around 10% a year.
  • Gas supplies from Norway (18-22% of UK winter demand) are subject to interruption, such as the storm-induced power cut mentioned above, and a technical problem in 2010.
  • Gas supplies from Europe by pipeline are subject to political problems, such as past disputes between Russia and Ukraine. They can also be affected by cold weather in Europe increasing demand there.
  • LNG imports have fallen dramatically since Fukushima, as Japan is outbidding the UK for gas.
  • Several of the UK's coal power stations will shut down for good in twelve days, with more to follow in the coming year. Some of our nuclear plants are also nearing the end of their lives.
The situation right now is that UK gas storage is at its lowest level for this time of year since 2010, and we may yet go lower than that, setting a new record. The difference is that our own gas production now is 37% lower now than it was then, comparing Q3 2012 with Q3 2010.

So while we may scrape though the tail end of this winter without any major panics on gas supply (though it's not over till the fat lady sings...), the low level of storage and limitations on supply mean that we are going to have to pay for a lot more gas imports over the coming months to refill the stores ready for next winter. So, we are virtually guaranteed to see higher domestic gas prices this year, and because about a third of our electricity is generated from burning gas, we will see prices rise there too, especially due to the shift of generation from coal to gas that will happen shortly.

If you've not already insulated and draught-proofed your home, now might be a good time to start...

UK gas crunch...

Gas supply is looking very tight for the next few days...

Forecast demand is:
Sat: 300mcm
Sun: 320mcm
Mon-Wed: 360-370mcm

Bearing in mind how low storage is, and that the margin notice trigger level is currently around 400mcm but will drop as storage depletes, I wouldn't be surprised if we have a gas demand warning by the end of next week...

UPDATE: UK Gas Jumps to Seven-Year High as Norway Cuts Supply

Quick update to my earlier post, prices have gone even higher, and there's more info on what's going on from Bloomberg this time:

U.K. natural gas for within-day delivery jumped to the highest level since March 2006 as Norway cut supplies following a power failure at its Ormen Lange gas field in the North Sea.
...
Production from Royal Dutch Shell Plc (RDSA)’s Nyhamna gas processing plant in northern Norway, which handles fuel from Ormen Lange, is reduced by 53 million cubic meters a day today and 37 million tomorrow after storms caused a failure in the national power grid, according to Gassco AS. Output was cut by 57 million yesterday and 32 million on March 2, it said.

“The timing and extent of these offshore outages has unsettled a lot of people,” Craig Lowrey, a consultant at The Utilities Exchange Ltd. in Ipswich, England, said in a telephone interview today. “It highlights the nervousness of traders that we have seen this response.”
...
Inventories at Rough, the U.K.’s largest gas-storage facility, were at 6,909 megawatt-hours yesterday, the lowest level for the time of year since at least 2004, National Grid Plc (NG/) data show.

Start saving for your new gas bill now...

UK gas hits five-year high as unplanned outages squeeze supply

Just when you thought that there would be no gas supply problems, as winter was over...(see my earlier post on this)

Norway's Nyhamna gas plant connected to Shell's giant Ormen Lange field in the North Sea, which primarily exports gas to Britain, had an outage on Saturday after stormy weather, with production still down by around 53 mcm/d on Monday. The capacity of the plant is 70 mcm/d.

"It's the Nyhamna outage, Ormen Lange's processing plant. With storage so low and Norway running 100 percent it's gone mental," said one British gas broker.

In addition to the Norwegian outage, flows through Britain's St. Fergus terminal were reduced by around 7 mcm/d on Monday, creating an extremely tight supply situation.

Keeping an eye on UK gas supply...

Although winter should be nearly over in the UK, it's still pretty cold, and has been for much of the time since early January. As a result, while UK gas storage was looking pretty healthy earlier in the winter, it's now (again) at the point where it needs to warm up pretty soon or there are going to be some demand reductions enforced on industry.

The trigger level for issuing a Gas Demand Warning has fallen from 473 mcm/day (million cubic metres of gas per day) as recently as 9 Feb 2013 to only 395 mcm/day for 27 Feb 2013. Although demand is some way short of that (352mcm on 26 Feb), the gap between demand and trigger is now tighter than it has been at any other point so far this winter.

This is underlined by the amount of storage left at present (26 Feb):

  • Long range: 8,931 GWh out of ~40,000 max
  • Medium range: 2,871 GWh out of ~12,000 max
  • Short range: 203 GWh out of ~350 max
For comparison, that total GWh storage is equivalent to about 1,100 mcm, or just over three days gas at present consumption. So as you can see, it only takes one industrial accident or a change in gas trading to cause a problem. Let's hope it warms up soon...
