Wind theft.

Any news worthy story. Good things to watch at the Cinema, Theatre, on TV or have you read a good book lately?

I would suggest that the article is a little simplistic. My assumption is that wind in the lee of a turbine is more turbulent than that in front of it. And as we know, turbines like perfect laminar flow...
12x 340W JA Solar panels (4.08kWp)
3x 380W JA Solar panels (1.14kWp)
6x 2.4kWh Pylontech batteries (14.4kWh)
LuxPower inverter/charger

(Artist formally known as ******, well it should be obvious enough to those for whom such things are important.)

Graig Fatha had a 2% reduction taken off the P75 value for the share offer because it was at the far end of a long line of turbines up wind from it in the prevailing westerlies. But it does tend to out perform in an easterly as its the first in line.

From share offer doc,
"......... yield estimates include a 2% reduction applied by Ripple as a conservative measure to account for potential blockage and induction zone effects."
19.6kW PV > 114MWh generated
Ripple 6.6kW Wind + 4.5kW PV > 34MWh generated
7 Other RE Coop's
105kWh EV storage
90kWh Home battery storage
40kWh Thermal storage
GSHP + A2A HP's
Rain water use > 530 m3

Interesting article.
Reminds me of that amazing photo of cloud formation in an offshore wind farm due to the pressure changes and the obvious wake formation
