Wind Turbine Bases Understanding the problem.
Typical Onshore Wind Turbine Base
Capital & Environmental Impact • 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: o Original bases are left in the ground and covered with topsoil o 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).
Collaborative Approach Working together to develop solutions.
Industry Working Group
Feasibility Study • 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
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
Funding • Project cash costs will be covered by CSIC, SEPA and SNH, in excess of £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?
