Ripple Energy wind farm?

Write up in today's Guardian piqued my interest. Great idea, but a poor investment. According to Ripple's calculator a 2500kwh/year household should invest £2,625. It says, indicatively, this will give £5,875 savings after 40 years. That's a compound interest rate of only 2.03%.

Can get better returns elsewhere. 

those annual returns don't include index linking

Let's assume inflation settles back down to 2.5%. That's double the returns after 40 years, so 4%. Can still get better returns elsewhere. These schemes have no FSCS protection and returns are uncertain. They've got to offer more. Currently for ultra green altruists only.

Hi, if you see my post of the 15th March, I've already done the calculations (I ran up a quick spreadsheet). I think you've underestimated the returns by missing the fact that the returns (as stated) don't reflect index linking, and that they too, could be invested and compounded.

Also, your conclusion that 2.5% inflation over 40yrs is double, is also incorrect, as again you've excluded compounding. The actuall result would be x2.68 not x2. So ~5.45%.

The build cost at around £1k/kWp (£1/Wp) doesn’t seem particularly competitive when compared to domestic solar which until recently was available at around this figure. (My installation split over 2 roofs came in at £900/kWp in 2018). Yes there is the grid connection to consider but the economies of scale of an array of this size and ground mounting instead of roof mounting should present considerable savings not apparent in the estimated costs.

I dont know why you are comparing build costs but if you are inflation since 2018 is 31% and pay rates for skilled trades have gone up more than that.

As I said earlier the cost to me is 3.5k and not 12.5k and that is without having to replace batteries or inverters

Kirk Hill turbines have started arriving in Ayr.  There's an option on the members news feed to track the shipments if you're sad enough to do so. I am

I think enabling subscribers to track the shipments of the components for the wind farm at Kirk Hill is quite a good idea as it increases confidence that these will be delivered on time.  In the Facebook video of one of the deliveries, the FD says that we will shortly see the nacelles being unloaded from the ship but the video stops before this, I wonder if they arrived?  I guess what most Kirk Hill subscribers will be waiting for is news about any progress towards getting the delayed infrastructure in place to enable power to be exported from the wind farm.

Can I just jack into this thread.... we've got a big investment in kirk hill and love all the updates. However, we're now about a year away from generating electricity I'm wondering how others are beginning to plan with being with the right type of energy provider.... currently we are unhappy captives with Shell energy (moved over to them without any choice when our previous provider went bust). We have an electric car which we charge at night, so we're looking for something Ripple-compatible with cheap night time rates..... thinking Octopus?

Also I have no idea if 'deals' are starting to appear now that the cost of energy is starting to come down...

Definitely switch to Octopus. If you have rooftop PV, Flux may be your best bet. If not, Intelligent for electric and Tracker on gas appear to be very lucrative!

I’ve been with Octopus over 5 years and would highly recommend them. Always had very prompt customer service and managing your DD/credit is very easy. I don’t have an EV but their Intelligent tariff is a great rate at the moment. Find a friend who’s an existing customer of theirs and get yourself a referral code for £50 credit apiece.

Yep I too agree.  Very happy with Octopus.  I'm on a Go tarrif with cheap night time charging which works very well for me.  Customer service also appears to be very good from mine and others' experiences.   Note the Intelligent tariff is only available if you have the right car or the right charger.

Flux looks like it needs batteries as well as PV?
