An assessment of the impact of pre-construction energy yield analysis on post-construction budgets

Introduction

Natural Power considers the implications of pre-construction analyses on the budget for post-construction performance.

Approach

Following a validation of the pre-construction methodologies, the budget numbers are compared with operational yields to determine underperformance.

Main body of abstract

Perceived turbine underperformance based on pre-construction energy yield analysis has been a common theme across the industry. To rectify this, Natural Power has conducted a pre-construction methodology validation to determine the limitations of the pre-construction methodology and to incorporate these findings into producing a high quality energy yield product. Looking forward, Natural Power examines how wind farm energy budgets derived from pre-construction energy estimates, can allow for a better understanding and assessment of wind farm and individual turbine performance.

Conclusion

The results of the analysis show the importance of accurate pre-construction energy yield analysis and the implications on expectations for the operational wind farm.
