What is being bought

Published requirement description

Yorkshire Water (YW) and Kelda are seeking to engage the market to discuss their planned deployment of new on-shore wind turbines - specifically regarding bankable wind data without the requirement for 12 month Met Mast or LiDAR campaigns. Work done to date indicates deployments of 1-3 turbines at each location, with 7 sites under consideration initially plus 2 repowering sites. As YW and Kelda look to expand this programme, they anticipate a small scale wind development programme in addition.

The deployments would be on YW operational land and would directly power the adjacent operational site, offsetting grid purchased power.

The purpose of this notice is to open discussion with wind data analysts, modellers and providers. We would like to work with wind data specialists with a proven track record of securing wind turbine project finance having used modelled wind data, processed into a bankable format, without a 12 month LiDAR or Met Mast campaign. Data must include:

  • Annual Average(mean) wind speed (at hub height)
  • Once in 50 years 3 seconds maximum wind gust
  • Weibull Shape factor k
  • Wind shear index IEC alpha
  • Characteristic turbulence at 15m/s, or the full turbulence graph
  • Wind farm output at P50/P90 levels (gross and net yield)

The following can be provided:

  • Wind turbine locations
  • Wind turbines hub heights
  • Wind turbine makes and models
  • Any other relevant data

YW and Kelda are looking to partner with a single data provider who can provide bankable wind data which will be used for accurate financial modelling and securing project finance.

About this data
  • Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
  • Two views, kept apart. The authority’s own track record and the wider market for the same kind of work sit side by side and are never mixed. Where the local picture is too thin, a figure widens to a broader market and says which one it used.
  • Forecasts are labelled. The price forecast and its range, possible competitors and the earlier-work matches are our estimates from past awards: not published facts, not win chances and not price advice. Official notices do not say who is bidding.
  • Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.
