I think Frank is referring to certain illegal activities. The discrepancy is probably due to errors in the way the data is collected.

A good half of freight trucks could be driven onto flat bed trains for the bulk of there journeys like they do to get them through the channel tunnel.
It would save rubber pollution from the tires and lots of diesel fuel and with the track side spaces filled with solar panels and wind turbines could be fully renewable in summer or on windy days. It would get a hell of a lot of truck miles electrified at no cost to the freight companies and would transfer wear from roads to rail this being cost neutral. The truck drivers get there mandatory rest periods on the train so it is a winner for them too. There was a grow house growing "bibgoweed" in the newspapers the other day.

If an update occurred, that could make a difference. One possibility is that the difference is attributable to losses in the transmission system. This means that more actual power is generated, as measured at source, than consumed by the load. Also, bear in mind that the Interconnects are bi-directional, with zero at centre scale. At the current moment, the E-W Interconnector between Wales and Ireland is exporting 540Mw to Ireland and thus reads -0.54GW whilst we are importing 1GW via each of the French, Dutch and Belgian interconnects Check the Info tab. Not only will you find out more about it but you will also find a contact email link. Someone has put a lot of effort into building that site and keeping it running 365 days of the year. If there is an error, then I'm sure he would be grateful to know about it.
Something that's sometimes overlooked by folks with wind contribution on the gridwatch site is that not all wind generation is metered.....This is from the info when hovering over the demand meter:
"Demand: This is the total demand of the entire country (plus or minus exports) less any unmetered generating sources like wind but including an estimate for solar" Lawrence.

Are you thinking of a new range of mega-sized Dinky Toys? The Channel Tunnel has the extremely large loading gauge of 13' 5" wide by 18' 4" high but, after getting to Folkestone this shrinks to 9' 0" x 12' 10" at its highest point with an 8' 9" radius, so you might have a teensy-weensy bit of trouble squeezing the trains under bridges and through tunnels.

Don't you remember when Merkel wet her knickers when all her windmills stopped turning? She shut down all the nuclear plant in a knee jerk reaction to Fukushima , re-opened a few coal fired stations burning Lignite - the most polluting coal on the planet - and placed her trust in her windmills and solar panels. Then, in November, a large High pressure system drifted over Germany and stopped. No wind, no sun, and sub-zero temperatures all over the country. Surrounding countries had to bale her out, which also meant using that dreaded nuclear electricity from France. We only had the 1GW Dutch and 2GW French interconnectors but we opened up mothballed coal fired stations and the interconnectors worked flat out non-stop. This country became a net exporter of electricity for the first time ever. If the same thing were to happen to us, with the best will in the world, neighbouring countries would be powerless (sorry about the pun!) to help us because we are surrounded by water which reduces the options to 4GW from the combined European interconnects and 280MW from Ireland. That won't go very far ...

Which is why making energy policy by kneejerk reaction is a bad idea. Especially if you suddenly decide to take a substantial fraction of your country's generating capacity out of service without some very good engineering reasons. One of the many mistakes that have been made and will continue to be made on the route to a low carbon future.
Unless you have huge amounts of storage or massive interconnects (like the Desertec project, nice idea but I don't see it happening anytime soon) you need backup generation on the system. Since it's only going to be used occasionally it needs to be low capital cost and easy to start. Fuel efficiency is secondary. Open cycle gas turbines are a likely solution. How about Argentina and several other south American countries recently. Major fault causing cascade failure perhaps? I don't think Europe (including UK) has ever experienced a major cascade of failure. The 1987 storm took out a lot of the southeast but the grid as a whole was OK. The US/Canada has had a couple of major failures like this. https://en.m.wikipedia.org/wiki/Northeas...ut_of_2003 I was in Vancouver during that outage.

It would have to be a new extension from Folkston with a clone of the Queensferry crossing at Dartford or Tilbury and then the first stop at Brentford by the M25 and then up the west side of Lincolnshire to York or the M62. Normal trains would be fine with mandatory automatic wheel chair ramps on all doors to go over the gap. No more moaning about lifting those pavement hogging push chairs in and out. |
