Re: Octopus Energy Tech Summit

Well thats deffo John in the middle Moxi Correct there. How did you know? Interesting and worthwhile day out. My biggest takeaway was that Kraken now 'controls' over 500,000 EV chargers and heatpumps (I think worldwide, not UK) and that gives enormous flexibility to support grids lower net cost.

Octopus Energy Tech Summit

Last week I got an email inviting me to apply for one of 500 free tickets to this event 23 June.

https://energytechsummit.co.uk/

Today, I have got an email saying that I have won a free ticket. Apparently over 25,000 customers applied.

Anyone else lucky enough to be going?

Re: Pitlochry hydro

I understand the frustration of the community, but it is also clear that neither the community nor Lesley Riddock have any grasp of economics. Whilst the operating costs of hydro and wind are low, there is still the upfront capital cost of the plant and distribution network. It seems that they expec...

What is not mentioned is that overbuilding of PV and wind is probably a good partual solution and a fig of 130% overbuild is often proposed as the ideal amount.
Has anyone considered what changes will be needed to the constraint payment mechanism with 130% overbuild?

Re: EVs hit 32% in the UK

Full marks to CleanTechnica for not including self charging hybrids as EVs.

However, if they did, the share would rise to 46%

The only condition was t...

Re: Half price IOG tonight

So I ran through the night on battery power. Didn't plug the car in from just before 1100 yesterday. Battereis got through effortlessly even with the AC running low-and-slow all day.
