Potential power outages this winter

Gas in the pipes is under pressure but not to provide storage.

Very interesting as in my interview to work at a gas pipeline company i asked why no holders.
The answer i wa given was it is stored in the pipework.

I know that there quiet a few pressure gauges used are 70bar.

If they stopped feeding gas into the pipelines how long would the gas already in the pipelines supply the UK?
 
Thousands of miles of largish diameter pipe at 70bar does provide some amount of storage but not a huge amount. It's certainly been adequate to balance the minute by minute and hour by hour demand changes for most of the last 20 years. On a longer time frame Rough and the gas fields themselves obviously moderate input and output. Storage is always a timescale dependent metric.

Gasometers were originally for storing Town Gas made from coal and distributed locally on low pressure small diameter pipes. The relative storage capacity of the pipe network itself being far lower, particularly in the days of local rather than national gas networks. I would guess that Town Gas production was probably fairly linear and demand was peaky so thos storage tanks were necessary. These days I would guess that on a daily cyclce basis the national gas gris fulfils most of the same function.

British Gas-owner reopens storage ahead of winter

Centrica admits reopening the gas storage site is "not a silver bullet for energy security".

Some good news although we need more storage than this.

Dailies for gas to go up then, they were high in the summer due to EU filling their gas storage.

Which is better cheaper dailies with shortages, or cuts with more expensive dailies?
 
Received an email from E.on today inviting me to take part in "a series of Energy Shift events throughout winter" where I could "earn" around £100 over winter if I meet their targets*.

*£100 is based on the average user hitting their turn down targets, over 29 events over the winter period between November and March, based on an assumed incentive payment of between £2 - £4kWh.

so that averages out at saving ~1Kwhr electric ( 100/£3/29 ) probably on 29, 2 hour 4:30pm-6:30 slots
pretty challenging if you are averaging 6kwh/day like us, for starters no cooking until after 6:30

Interesting stuff @jpaul. It'll certainly be challenging especially as going in to winter we'll all be using more. I'm averaging about 12kWh per day so probably use too much for the scheme to work for me. No harm in trying though, you aren't penalised for not meeting the target.
 
Not to be that guy but the majority of pipelines in the UK are above 70 bar. With the highest rated for 97 bar.

The gas in a ball valve cavity on the 48 inch pipeline can supply a village for a month to give you a idea of capacity of the pipeline.

I assume the events would line up with Octopus, but maybe not
The Octopus ones are during peak time, I think they suggest 1-4 hours max, i would guess normally breakfast or evening but we will see
Its by 30 minute window, so each is individual not all added together

This is a national grid based thing so every energy supplier should do it I think
You need a smart meter and on 30 minute settings for Octopus but all would be the same I would assume
 
The mechanism by which the cuts might occur isn't so clear -
if there aren't enough renewables, then they'll choose to preserve the domestic gas supply(& avoid dangerous depressurization), rather than using gas to maintain power generation;
this should mean if they told people to seriously turn down gas heating the electricity cut might be avoided, which you would have thought many people would prefer, to a power cut.

Not sure, some people have reacted very bad to me suggesting they turn down their thermostats or turn off their heating for many its a red line.

I suppose the government is trying to not be unpopular by choosing to not do a "turn down your thermostat" campaign. I can imagine headlines about people freezing in their homes because the government couldnt secure energy supply.
 
If it does happen, I'll wrap up extra warm, and hope for a clear night sky where I can sit out in my garden with a.hot flask of Bovril and stare at the stars.

But we all need to.

I'm quite comfortable with a hoodie on in about 12c inside out of the wind.

I appreciate there are some more vulnerable.

But most of us don't need to be sitting 20c houses.

Turn lights off, only put just enough water in the kettle etc. If we all start making changes it'll add up
 
Depending on how large an area what happens to mobile phone masts do they have generator backups or would one be within signal range but outside of your area.

With more of us moving to digital landlines or none at all I was just thinking in the case of a medical emergency or fire etc ?
