Generator installed capacity

No, that's the official figure. The 50/55 is just a marketing 'rated' output. Sustained output of 80 is achievable, with peaks over 100.

Tic 80
Dnc 79.5
Plate on generator 73

As I said conned by the salesman. Its only a 50kw machine but they plated it at 80kw. All turbines do more then there design output as its obviously dependent on wind speed but normally you downgrade say a 900kw downgraded to a 500kw so you get the required output at a low wind speed. The E3120 is the other way round its only a 50kw machine that requires a higher wind speed to obtain the 80kw.

Whatever. The question asked was about installed capacity - Ofgem is 80 for a e-3120.

Your point about 900 v 500 was just a scam to get the benefit of the blades of a 900 turbine at lower winds, but get the 500 fit.

As regards questioning my ability to assess sales patter, power outputs are pretty much irrelevant; annual generation is what counts, and I'm more than pleased. My experience of the rating valuation is that it's this (or actually income) that the voa are interested in.

You see thats where my view differs. To me the 900 to 500 is not the scam the real scam is the 50 upto 80 as the average windspeed will not even give you 50kw yet if you declare the figure at a nameplate 80kw your being taxed on a rate rarely achieved in practice.

I'm not sure the 50 v 80 debate makes any difference to tax (rates) as it's income they're interested in. Both figures are in the same fit band.

The 900 story was a way of getting the output of a genuine 900 machine on all but the windiest days (when power was capped), whilst claiming the higher fit of a 500kW. That doesn't sit well with me.

But a genuine 80kw machine will generate far more income than the 50kw E3120. ie for exactly the same windspeed. I think the rates calculation should be based on the set output for the turbine at say 5m/s that way you dont have this mickey mouse lottery of what the manufacturer declares as nameplate output.
As for the 900 I would have bought one if I could have got planning as the larger blades would have made it far more effective at lower wind speeds.

They have asked for actual generation (and income and expenditure figures) for the last 3 years. First time we have had to supply any data to the Valuation Office. Our local council has always levied us for business rates but in the first year we applied for rural rates relief so have never paid anything. The turbine is a separate business from the farm.

That's exactly the same as me. I'm in the process of collating income/expenditure and essentially going to be taxed on profit (again). That's why the power rating doesn't appear important.

Like you I'm getting relief currently, but am acutely aware this could disappear with a moments notice.

Is this the VO 6056 form you are filling in Had a reminder the other day that I had to send it back by Tuesday otherwise I would receive £100 fine. I had not received any form. Already paying business rates here for wind think this is for the next revaluation

In that case its easy your generation capacity is total generation divided by number of hours in a year and I doubt that it will be anything like 50kw. I thought rates are only payable over 50kw therefore declare your capacity as the year with the highest figure.
Just looked again at the legislation and I cannot see anywhere where it quotes nameplate capacity. Maybe someone else can confirm. Does say that for micro generation it needs to be 50kw or below and in the example rateable value is 14 pound per kw so 80kw turbine would be RV 1120.

Yes, we had not received the form either, only the reminder, had to download the form off the internet.

We have given all the responses required on actual (actual MwH generated), but there is a question early on which asks about what equipment and what is its generator installed capacity, which is what I was asking about originally.

In that case I would use the actual figure achieved if you have 3 years of figures than average over 3 years. It does not mention nameplate capacity.
