Nant-y-Moch Wind Farm


According to SSE, the developers of the Nant-y-Moch wind farm, the annual energy output would provide for 65,000 homes (at 4.7MWh per household per year). This equates to 305 GWh/yr.

Annual UK per capita electricity consumption (not just household but shops, factories, street lights etc) was 5,692 kWh in 2009. Therefore Nant-y-Moch would provide the TOTAL electricity consumption for 53.6k people. Or nearly one in a thousand of the UK population. Just one wind farm!

    For comparison Cefn Croes metered 162GWh/yr for 2011

    Annual production from the Rheidol hydro power station is 85GWh:

      So, Nant-y-Moch would would be almost twice Cefn Croes wind farm and more than three times Rheidol hydro. And these three together would provide TOTAL electricity for 97,000 people. Not too shabby :)

      When the wind blows. Remember that the industry agreed dispatchable energy for an on-shore wind farm is just 5%. 95% back up required. On February 18th 2013 the realtime data figures show that of 57GW requirement from the Grid (cold, clear day) wind energy provided just 0.4% even with 5GW instralled capacity. Fairly shabby for the capital cost outlay and the subsidy would venture. Sorry, we live in a real world where collecting derisory amounts of unreliable and intermittent electricity from widely dispersed sites in remote rural locations with kit that lasts a maximum of around 12 years is never going to be economically viable. Germany, Holland and Denmark have already found that out to their cost. We need to learn rather quickly and invest in long term and sustainable energy saving and reliable and flexible load following energy sources. These measures would have the added advantage of providing hundreds of real permanent local jobs.

    Hopefully the back up will be increasingly dispatchable, pump storage, hydro, or gas, the latest versions of which can be turned on in 30 minutes.

    So when the wind blows we get energy at zero variable cost, and when it does not something else is dispatchable.

    Spain sometimes gets half its electricity from wind, that cannot be called derisory? A glance at a wind map of Europe shows that Wales has far more wind than Spain.

    In Australia, wind is coming in cheaper than new coal?

    90% of our energy is fossil based so I can only agree completely that we must "invest in long term and sustainable energy saving and reliable and flexible load following energy sources".

    Local jobs are a separate policy area, the priority in this debate is to identify solutions to climate change. The atmosphere is a global common.
