Re: Airtightness test booked - how to get the best from it?

If it is windy, go round the house with a candle or wax taper to see where the draughts are.
If it is cold, go round with a laser thermometer and see if any doors or windows etc show cold spots where seals or draught proofing is missing.

Re: Grid forming Batteries - mimicking spinning reserve.

There is definitely something to be said for the simplicity of a flywheel. It does not need FF to power it as it takes its power from the grid until it is up to speed and then it absorbs surplus power on the grid when the frequency goes up and releases it when the frequency goes down. National Grid ...

Re: electricity import record today ?

I blame Ofgem for where we are now. Years ago, it was all talk of fixed price contracts (such as Octopus's PPA for Graig Fatha wind farm production) for most power generation with the spot price only filling in the gap and selling over commitments to buy. Ofgem's contracts for difference encourage/r...

Latest posting on Republic Europe / ex Seeders

"Octopus CEO on X is alluding to the fact they are taking a look at Ripple through the administrators"

Re: Jump Starter

The e-bike battery is most likely lithium. Can it handle the high currents needed to jump start?

Re: Ripple energy "strike off"

Typical Sun article, They do not understand that the GF and KH Coops are ring fenced from Ripple and are still operating as going concerns. They are not owned by Ripple and the administrators/liquidators cannot size their assets. There should be no loss to investors in GF and KH. Probably the same f...

Re: Ripple energy "strike off"

Ripple's business model of financing projects via a Coop structure was always doomed as investors were limited in the cumulative amounts that they could put into Ripple projects. Whilst it made sense at first as the regulatory burden of raising the capital was lighter and thus cheaper for a Coop tha...

Re: Camden's Trojan Horse

It looks to me as if the cable and charger adapter are permanently connected and thus the car owner needs to carry two cables around. (Or three with a granny charger).

Re: Octopus saving sessions coming 1st Nov

Frankly, I would like to see Octopus offer IOG customers the Flux export rates for evening peak hours instead of opting into Saving Sessions. This would better align behaviour with the greater good instead of encouraging 'rinsing' on non DFS called days which actually makes the evening peak demand w...
