Your wind farm share effectively covers the cost of your electricity, but not the distribution costs / overheads. However, as you know, there are ways to get your electricity much cheaper than the standard tariff rates.
When the scheme was launched the credit, for your share of the windfarm, was expected to equate to less than 5p per kWh. However, things have changed and the current credit, based on current prices, is calculated to be 18p per kWh.
Now 18p per kWh isn't enough to cover all of the cost of your electricity if you are on a standard tariff, but it is more than enough if you are purchasing all/most of your electricity at night rates.
Having purchased my share of the windfarm (100% of my current usage), I intend to purchase enough battery storage to cover what I would use on most days. Then I will switch to Octopus Go (current night rate 7.5p per kWh). Then during each night period on Octopus Go, I will recharge my storage batteries (plus my EV and anything else that can be charged at any time), and draw down on that stored electricity through the day.
My current estimated return on the up front investment is approximately 5 years, less if electricity prices rise further, a bit more if prices were to fall.
