In the vendor side

Nabla has the methodologies and technology to unveil the life extension and performance improvement potential of the wind assets subject to rotation, and accompany the vendor for defending these assessments in the bidders sessions and Q&A. In this context there is normally time to run loads simulations, perform inspections and run reliability models.

The typical Nabla will build the vendor TDD for wind assets based on:

1. Exploratory Life Analysis (P80), to map the fatigue related risks in the long term and deploy preventive strategies for its delay or mitigation. This analysis can also unveil performance improvement potentials through tailor-made retrofits/partial repowering.
2. Reliability Models, to map the random and non-fatigue related risks, so to complete the Exploratory Life Analysis picture.
3. Life extension inspections (visual check in particular key points related to life extension programs).

In the acquisitor side

Lead times become critical, and there is normally no time for running loads calculation for all the assets under evaluation, in such case Nabla provides the following approach:

1. EYA review, identifying Technology/setup risks and mitigations.
2. WTG design review, identifying Technology/setup risks and mitigations.
3. WTG life expectancy (type vs site) giving a high level map of failure rates, fatigue and random events, plus recommended preventive actions. If lead time allows it Nabla will recommend a representative part of the portfolio to be analysed under Exploratory Life Analysis.
4. Review of CAPEX/OPEX Financial model assumptions.
5. Review of Vendor's life report, if any.
6. VDR GAPs, red flags, Q&A, meetings if needed, reports.
