Wind Turbine Bases

Understanding the problem.

Typical Onshore Wind Turbine Base

• Repowering (replacing wind turbines) within an existing wind

farm is to replace it with a new concrete base and not re-use existing foundations

• Capital Expense & Environmental Impact:
• Original bases are left in the ground and covered with topsoil
• A new base is then constructed to take the new (often larger)

turbine

Capital & Environmental Impact

• Valuable steel and concrete is abandoned in the ground, including

significant embodied energy

• A new excavation is required for each new turbine base, leading to

more habitat disturbance and (often) the excavation of peat (which generates carbon emissions)

• Current approach necessitates a change to the wind farm layout
• The old turbine bases will become a constraint to future wind farm

layouts (unless a solution is delivered in future to allow new bases to be installed on top of old ones – this is not currently possible).

Capital & Environmental Impact

Collaborative Approach

Working together to develop solutions.

Industry Working Group

• ENGINEERING: Identify concepts in Engineering terms (new bases

and retrofit solutions):  Total Lifespan 60 years  Max Tipping Height to be considered  Engineering design to be based on gravity base system

• COSTS:

 Scope the comparative costs to the existing model

Feasibility Study

• MANUFACTURER ENGAGEMENT:

 Secure Industry Buy-in leaning on existing networks

• ENVIRONMENTAL IMPACT:

 Identify the environmental benefits  Examine any long term effect of leaving the bases in situ

Feasibility Study

Next Steps

For the Project, and CSIC.

Work Packages

• Proposals received from members within the Working Group and

responsibilities allocated:  ENGINEERING: ARUP  COSTS: SSE / Scottish Power Renewables  ENVIRONMENTAL IMPACT: University of Glasgow  MANUFACTURER ENGAGEMENT: Scottish Enterprise, SSE & Scottish Power Renewables

• Initial studies to be delivered between January and February 2017
• Final report collation delivered for sign off March 2017

• Project cash costs will be covered by CSIC, SEPA and SNH, in excess
• f £20K
• Collectively all members of the working group are committing

resources and time to deliver objectives

• Project interest?

 Potential for future deliverables  Interested in being involved?
