    Hi guys,

    I'm a bit pushed for time today and maybe the info I have here isn't enough but I'll give it anyway.

    I got a call earlier from somebody with a business and the landlord is looking at installing a wind turbine and said that it generates 24 kw. does this make sense and if so, how much would that run (approx)

    Thanks

    how much would it run?

    nothing if the wind isnt blowing. I assume there are going to be batteries used for storage - these at the moment afaik are very expensive..

    Do you know the current electricity consumption of the business?

    Has the site had an assesment done yet?

    Thanks snyper,

    To assess the site, you need to know the actual power curve of the turbine. A turbine might be 20kw at a wind speed of 15m/sec, but the same turbine can also be described as a 10kw which is what it might produce at 10m/sec.

    ESB won't permit a 20kw turbine to be connected to the grid as far as I know, so there are problems there...

    Why is that Quentin, is it considered a commercial turbine at that stage?
    If so at what point does it become commercial?

    I don't know the reason for the 10kw limit, but the overall intention of the subsidy is that houses can produce their own requirements and export surpluses. There is another limit that the ESB can refuse if, within one district the total domestic power exceeds 40% of the total capacity of a local sub-station. Some localities don't have wiring that can take 20kw.

    But there are other anomolies in what is and is not allowed. For example, ESB insists on unique Irish variations to the EN standard for inverters which puts quite an obstacle on what is available here. The standard of power they demand is often not met by their own supplies. Wind inverters regularly cut out because the limits they are obliged to conform to are not being met by the grid. :mad:
