Re: Hornsea offshore to have a battery pack

I suspect in the background batts allow the wind farm to quote for a greater supply and reduce curtailment. Wind that would have and maybe still is? curtailed and therefore at zero cost can be fed into the grid at max price. Agreed, but it also assumes that the curtailment is not due to the link fr...

Re: Grr...

If they are the sort of people who holiday in Cornwall (not solely but for some of their holidays), it would not surprise me if they were put off an EV because of the poor charging infrastructure in the west country, particularly in the holiday season. Fancy having to queue up with all the Porsche T...

Re: Berlin's oldest passenger ferry goes electric

I expect it has a lot to do with speed. Both the ferry and your barge will be limited by their speed length ratio. Generally, for displacement, ie non-planing hulls, max hull speed = approx 1.3 * (waterline length)^0.5 where hull speed is in knots and waterline length is in feet. The constant, 1.3, ...

Re: Avoid Scottish Power's SEG tarrif.

Consider making a data subject access request. This should provide you with a record of every phone call, email etc. Also ask for everything to do with your property and MPAN and then they should be giving you a record of when they applied for export MPAN to the DNO and when they received it etc. Al...

Re: Part ownership of a Ripple Wind Turbine, fancy it?

If, on the home page for GF members, one selects the current month (the default setting) and hovers over a day, it will show the cash earned and either confirmed or estimated. All days shown, up to Thursday 18 April, are confirmed which suggests to me that they are actual meter readingsand that the ...

Re: Part ownership of a Ripple Wind Turbine, fancy it?

I've already put a reservation down, just got to decide how much to put in. Annual consumption last year was 1400kWh, but the future will see an EV and hopefully a heat pump. I see that evidence is only needed for 7000kWh and above, and you can increase by a standard 3000kWh for an EV, 4000kWh for ...

Re: Part ownership of a Ripple Wind Turbine, fancy it?

Quick look at the numbers shows that to buy enough to generate 2,900kWh per annum would cost:

WB Project 4 £1,900
compared with
GF Project 1 £1,878
KH Project 2 £1,580
DW Project 3 £3,000

Looks a fair price, but I am at my 120% limit, so I won't be investing
