Six small wind turbines gain MCS; micro-hydro still 'in transition'

Posted by Cathy Debenham on 20 January 2011 at 10:50 am

Small wind turbines and micro-hydro systems have been the anomaly in the MCS system since the feed-in tariff was introduced in April last year. For an installation to be eligible for the financial incentive both products and installers must be accredited by the Microgeneration Certification Scheme (MCS).

However, when the scheme was introduced only a handful of wind turbines had been accredited, and there were no accredited installers or products for micro hydro (smaller than 50kW).

The answer to both problems was a transitional list of products (and installers for hydro) that would qualify for the feed-in tariff. In the case of wind turbines, this list closed at the beginning of January, and there are now six models of small wind turbine eligible:

Evance R9000
Gaia Wind 133 - 11kW
Proven P35 [suspended pending investigation of failures 21/9/11]
Proven P35-2 [suspended pending investigation of failures 21/9/11]
Skystream 3.7 and
Skystream Marine 3.7

Trade body, RenewableUK, anticipates that 10 to 12 small wind turbines will have MCS accreditation by the end of the year.

Micro-hydro remains an anomaly. When the feed-in tariff was introduced last year there were no MCS accredited products, for the simple reason that there were no agreed standards for the micro-hydro turbines to be accredited against. There weren't standards for installers either.

Things have progressed since then, as draft 1.7 of the product certification scheme requirements were issued by in December 2010, and there are now 15 installers and 11 turbines on the transition lists. The micro-hydro association website is the best place I've found to keep an eye on developments.

Hi Richard

We are still waiting for the government's response to the 2B consultation on the feed-in tariff which contained the new post 30 September tariffs. The proposals are that all wind installations up to and including 100kW would get 21p per kWh. The wind industry has been lobbying against that, it remains to be seen whether it has been successful.

There are now 22 MCS accredited wind turbines - you can see the list here. I am not in a position to comment on the performance of any of them, but have asked an expert to do so. Keep an eye on this page.

Dear Cathy & anyone else on the know.....

1)Have you any comment/s on my quiery as to Woody's views about the Skystream 3.7 - 2.4Kw and/or the Evance 5Kw turbines ?...your 27/09/2011 posting on the withdrawal of some Proven turbines refers.


2)Have you heard of any problems with the smaller but very keenly priced FuturEnergy 600/1000W turbines (as featured on the Saving Energy Online website)........they appear to have no MCS accreditation unfortunately ? have any other small turbines been accredited since your very limited 6 x MCS approved 20/01/2011 posting list ? 

3)Any firm news or rumours about what will happen to small turbine Wind Power FIT rates after the present end of September 2012 deadline rates ?....As I am considering an install to compliment my recently installed 4Kw PV system subject to PP & DNO approvals.....and I don't want rush into anything....if I don't have to !
