Today we have imported a refresh of the national cumulative data available within VentusAR. This is dataset contains information the size and location about every turbine in Great Britain and is available within the VentusAR portal to make it source accurate cumulative data for a project you are working on. This dataset has already saved some of our clients two weeks of tedious research work to get an accurate picture of the turbines and projects that would have a cumulative impact on their project.
I thought I would share a few statistics derived from this dataset. All data is taken from publicly accessible sources and is aggregated into VentusAR’s national cumulative database. The database is refreshed every two months. Please note:
- Data is based on information retrieved from the planning authorities public websites up to the 28th February 2015
- Based on this data source, there is no easy way to tell if a consented project has been constructed.
The total turbine and project counts for Great Britain as a whole (this includes England, Scotland and Wales) No data is included for Northern Ireland.
- 15550 Projects applied for (8739 consented or constructed)
- 29577 Turbines applied for (16206 consented or constructed)
As Linknode is based in Scotland, I thought we would start with looking at the turbines that have been in the planning system for Scotland. These queries can be run for other countries, regions or areas, next time we do a refresh, I will post some statistics for another area.
- 4937 Projects in the planning system (3047 consented or constructed)
- 12700 Turbines in the planning system (7374 consented or constructed)
Applications by Project Size
I wanted to know the number of single turbine projects in Scotland. This chart shows the split of single turbine projects compared to multi turbine projects. So approximately three quarters of the turbines are from multi turbine projects while approximately one quarter are from single turbine projects.
|Single Turbine Projects||3275||3275|
|Multi Turbine Projects||1662||9425|
Applications by Stage
Our cumulative database represents turbines and projects at different stages within the planning application system. We include all the data that we can find on the local authorities websites, so everything that has been rejected is included. The stages we include in the VentusAR national cumulative dataset are:
- Consented – the scheme has been consented – it may or may not be constructed.
- Proposed – a scheme is currently in the planning application system and is being assessed by local authorities
- Refused – the scheme has been rejected by planning authorities. The developer may appealed the scheme within the appropriate time limit.
- Scoping – a developer has asked the planning authority for an opinion of their scheme. No formal planning application has been submitted
- Screening – a developer has asked the planning authority for an opinion of their scheme. No formal planning application has been submitted.
- Withdrawn – The developer has withdrawn the planning application and this information has been marked on the weekly list.
As seen above, single turbine projects make up a quarter of the total applications that have been through or are going through the planning application system. To my mind, there are two key differences:
- 64% of single turbine projects have successfully got through the planning application system, while only 56% of larger multi turbine projects have been successfully.
- The refused rate is broadly similar (18% for larger multi turbine projects, 15% for single turbine projects)
- The withdrawn rate for single turbine projects is double that of multi turbine project (7% for multi turbine projects, 15% for single turbine projects).
These are best shown visually:
|Single Turbine Projects||Multi Turbine Projects|
I thought it might be interesting to know the average hub height and average blade length of the turbines that are in or have been through the planning application system in Scotland.
The average hub height off all turbines in Scotland turns out to be 48m, while the average blade length is 25.8m. Again I’ve broken these statistics down by single turbine projects (average hub height 24.1m, blade length 10.2m) and multi turbine projects (average hub height 56.2m and blade length 31.2m). The magnitude of difference between these sizes is shown visually below.
|Average Hub Height (m)||Average Blade Length (m)|
These statistics provide an insight into the volume of wind turbines currently in the planning system. I plan to do similar statistical analysis each time we import a new Cumulative Dataset into VentusAR to provide further insight into the wind turbine picture in the Great Britain.
If you have other suggestions of interesting statistics (most used turbine model at different sizes) or want to have a custom analysis and report created for a specific area, please email firstname.lastname@example.org.
The new VentusAR national cumulative dataset contains 15550 different Projects and 29577 Turbines. This data was sourced in the two months up to 28th February 2015 and loaded on 3rd March 2015. It contains all publicly accessible information about the project and the turbine locations, including turbine type and dimensions.
The dataset is used to obtain cumulative data provides a quick, easy and convenient way of discovering the picture of the other projects currently in the planning application system in a search area. More information can be found about the VentusAR national cumulative dataset on the VentusAR website.
This dataset is available to all, whether you are a VentusAR customer or not. Non-VentusAR customers can access the data by registering as a “portal-only” user. Please contact us for further information.
