OPEX Input Assumptions – Checklist

Offshore Wind Operations and maintenance (O&M) activities represent up to 40 % of total lifetime costs of an offshore wind farm (OWF). To evaluate the project economy, risks and opportunities, it is key to develop and continuously adapt an accurate Operational Expenditure (OPEX) budget covering the entire OWF lifetime.

Developing an OPEX budget based on a comprehensive mathematical model requires well-founded input assumptions covering all relevant O&M costs.  Therefore, a detailed OPEX model reflecting the total cost of O&M activities consists of several hundred input parameters – all of them contributing to the accuracy of the model.

This PEAK Wind Products Checklist provides a generic checklist on most relevant OPEX input assumptions for the development of OPEX budgets for offshore wind farms.  

What do you get from using this checklist?

• Understanding of the input assumptions requirements to be covered in an OPEX budget for OWFs
• Ensuring that main cost drivers in an OWF development project are covered
• Providing the structure to estimate a high-level OPEX for preliminary project feasibility assessment
