2) Hackney council does not know on how many days a year the proposed wind turbine will be able to produce its maximum power output.
3) Hackney council does not know on how many days a year the proposed wind turbine will be able to produce 50% of its maximum output.
4) Hackney council does not know on how many days a year the proposed turbine is predicted to be idling and therefore not producing any electricity whatever.
5) There is no site-specific data on the power-generation capacity of the wind turbine.
6) Hackney council references Ecotricity, a turbine developer with vested interests, in its discussion of modelling carried out on another local site.
Source: The blog author, Alistair Siddons, obtained this infromation from Hackney council under the Freedom of Information Act (2000), on 8 March 2010. Below is a full transcript of the response, as well as the questions I asked under FOIA.
Please note my slip in which in question 1 I describe the marshes as Walthamstow Marhes. However, the context is always clear and in the first line of their response, Hackney council refers, correctly, to the 'proposed wind turbine on Hackney Marshes.'

Dear Mr Siddons
FREEDOM OF INFORMATION ACT 2000 - INFORMATION REQUEST
Thank you for your email of 8 February 2010 in which you requested information regarding the proposed wind turbine on Hackney Marshes.
Your request has been considered and the information requested is below:
1) What studies were carried out to determine the average working capacity of the proposed wind turbine on Walthamstow Marshes? I would like to see a copy of any relevant report.
2) What is the proposed capacity in KW/hrs or MW/hrs of the turbine?
3) For how many days per year is the turbine predicted to be producing the maximum output of the turbine?
4) For how many days per year is the turbine predicted to be producing 50% of its maximum output?
5) For how many days per year is the turbine predicted to be idling?
5a) Have you published any of the figures relating to questions 3, 4 or 5? If so, where?
In response to the above questions:
The Council does not hold information in relation to Questions 1 to 5a. Ecotricity, a turbine developer - working with the Olympic Delivery Authority (ODA) and Lea Valley Regional Park Authority - has assessed the viability of delivering a turbine at Eton Manor, which is land adjacent to East Marsh. The background work undertaken for the Eton Manor turbine project has helped inform consideration of delivering a turbine of a similar specification at East Marsh.
