Wow £1500 compensation for a financial loss probably running in to the 100s of thousands Perhaps if proper levels of compensation (ie to cover the actual loss) were paid the maths would change for these projects but that is only right.

Interesting to see so much rewriting of history- the exact bits depending on which side of the political divide you sit. I think we need a better way of compensating for nationally important infrastructure. If I was going to get a pylon at the end of my garden that would reduce my house price by 200k but was not close enough to get compensation then I would be pretty peeved at being the one who had to take the hit for the greater good. Yes expensive, but why should the national interest mean unlucky individuals?!

I guess reinforcing local grid is an issue for the DNO not the energy supplier so the economics becomes more complicated. I also guess in theory the more short term storage is available the more prices will be arbitraged across the day and thus the less financial gain will be possible from possessing a battery - so the big differences between day and night rates will become a thing of the past and the return on battery systems will fall?

You might ask why we have put in place CFDs for the build out of wind that has no route to market? Surely a self-inflicted wound?

Could be wrong but I read it as 15 cells at 3.2v (48v total) making up a total of 314AH - so 15kwh Then 6000 15kwh cycles (actually more likely 13.5kwh) is 81mwh total throughput for the money

1140 for the batts SEPLOS V4 Kit and x16 Cornex 314Ah Bundle

IS it not possible to get 15kwh of battery for £1500 and £500 for an invertor? - that electricity can then give you 45kwh during the day from your heat pump?

There seems to be an odd puritanism with regards to AC. It is apparently fine not to want to feel too cold but want to not feel to hot and you are a selfish climate wrecker.

People chose to invest in a potentially risky new technology based on and agreed set of returns. Which other contacts should the govt renege on? I am a civil servant, you probably think I am overpaid and the government should unilaterally cut my salary including for the work I have already done this month?

Logically I think you are right but in reality people seem to be very short-sighted and only look at the up front cost - se for example EVs.

We had a weather comp boiler that modulated down to under 2kw and heated 24/7 with night time set back, the curve went to about 55 flow at -10 when it ran at about 7.5kw constant. WE had hot water tank in the loft so only needed a 18kw boiler which gave the good modulation. Funnily enough now with an oversized heat pump and a heat demand when it is mild of about 1-2kw we get a lot more cycling than we did with the boiler....

EVDB says 165 winter, 210 summer at 70mph. IMHO if you have home charging then the range number that matters is range while travelling at long distance journey speeds, being able to get 240 around town makes no odds.

So if it takes 2kwh of gas to generate 1kwh of electricity at the home (60% efficiency, transmission losses), then how come that kwh of electricity does not cost about twice what a kwh of gas does - we need some allowance for the cost of the gas-fired power station but I believe this is not huge on a per unit basis and perhaps the electricity transmission grid costs more per unit than gas transmission? - but still doesn't explain why electricity is more like 4x the cost of gas? So here is a suggestion. Given heat pumps give 50% more heat output per unit of gas (50% loss in generation and transmission but 3x gain in COP) why not have a heat pump meter and charge electric units used by the heat pump at 2x the cost of a gas unit (and build the necessary gas generation to support this knowing that by speeding up heat pump roll out we are reducing our carbon footprint)

Depends a bit how efficient you think a gas boiler is in terms of KWH of gas per kwh of heat.
