Wind farm life extension
We support assessment and implementation of wind farm life extension strategies for both specific projects and whole portfolios. We recommend early assessment and intervention to maximise long-term value of your assets, whether you intend continued ownership or divestment at some point before the end of life.
We work with asset owners, large and small, assessing their portfolios, providing independent, real world advice on the best life extension strategy to suit each situation.
To date, we have focussed on onshore wind farm life extension , as this is where the asst owners can benefit from immediate input. We don’t just rely on industry norms and assumptions. We visit your sites, engage with your team and review data on project history, performance and reliability, and use our experience of various turbine models.
At the heart of our approach are our own in-house calculations of nominal remaining fatigue life of a range of critical turbine components based on operating conditions for the turbines and component replacements. We supplement this with a structured failure-modes and effects analysis (FMEA). Based on our hands-on knowledge of turbine design processes, we can do these without any input from turbine suppliers and only limited data on site conditions. The more input data that is available (for example on turbine-specific wind regime, including turbulence), the more precise the assessment can be, but we also recognise that any analytical approach is only a guide to help increase assurance of safe ongoing operation and focus inspections and other risk mitigation activities.
We use this insight to evaluate the technical suitability of a range of possible wind farm life extension (or indeed, site repowering) strategies, taking into account your attitude to different types of risk.
We model the different financial impact of options to establish your least cost and highest value options, taking into account ‘hard’ and ‘soft’ restrictions. We deliver a detailed plan identifying a range of intervention strategies, assessed against investment cost, payback and risk. The resultant recommendations are likely to include an enhanced inspection schedule and possibly condition monitoring and component refurbishment options.
We take away the pain and increase the gain from wind farm life extension decisions.
