Although the wind always blows somewhere, it isn't always the right wind
in the right place at the right time.
With demand at 1030 of ~33GW, wind is producing only 9GW, but all the
interconnectors are on 'import' (a total of about 4.5 GW), hydro and
pumped hydro are contributing 1.3 GW and OCGT is on 0.7GW.
Solar is, as expected, 0 GW.

So much for Harry's prediction that we'll be exporting power when the
storm hits us. But I'm surprised both coal and OCGTs are up when
CCGT's don't seem to be flat out.
Can't speak for anywhere else, but our use of heating is affected by wind
over outside temperature. I guess it's the cooling effect of air moving
underneath the floorboards and through the roof space ?
That said we're gas heated :)
Just spent 30 mins replacing poly-carb panels in the greenhouse. Time
to replace, methinks, as many of the quarter-round strips that hold
them in place are split or borderline perished from 10 years of UV.
Yeah, I did wonder. I can see on a cold still day, the air acting like a
"shell" around the house so the heating seems more efficient. As soon as
the wind moves that around you need more heat to achieve the same
My biggest irritation at the moment is that being a bungalow, there's a
large (3C) temperature gradient between one side of the house and the
other. It can be 15C one side while 18C the other.
We'll be getting that next week according to the various
You wouldn't want to be living underground in Appleby at the moment.
Maybe they should hold the annual pikey gathering there at this time
If you have no insulation under your floorboards and the crawl space is
well ventilated then you lose a significant amount of heat downwards.
A good quality 80/20 wool carpet and underlay is quite effective as
insulation, but fitting rockwool on suspended netting between the
floor joists is even better.
A house with solid ground floors loses most of its ground-floor
heat loss, through the metre-wide strip of floor all around the
Building regs part L docs have lots of tables to allow you to calculate
the heat lost through that route. A house built on land that slopes down
towards the North, where the ground floor of the north facing rooms
is/are significantly above ground level will suffer badly when
there is cold north wind.
There are several CCGT generation operators who also own wind generation. If
they are located in the same zone then the cost of operating the wind generation
directly saves fuel and incurs no extra transmission network costs.
Both coal and OCGT will be there for stability reasons in the case of a system
split with a transmission disruption and to a lesser extent to cater for wind
output variation with the relatively high speed of passage of weather fronts,
something that challenges the prediction model immensely.
In the case of the coal generation it will be loaded to somewhere in the range
of 70-80% where dropping to 50% load or increasing to 100% load is relatively
fast and without much drama.
