[More contracts for small businesses and VCSEs](https://tendernation.io/opportunities/for-small-businesses) ## About this tender 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.
