Understanding the Question

When you're asked, "Explain how you would conduct a wind resource assessment for a potential site," the interviewer is probing your technical knowledge and expertise in the field of wind energy engineering. This question is designed to evaluate your understanding of the critical steps involved in assessing a site's suitability for wind energy generation. A comprehensive wind resource assessment is fundamental to determining the feasibility and potential energy yield of a wind farm, which directly impacts project viability and financial forecasts.

Interviewer's Goals

The interviewer's primary objectives with this question are to:

1. Assess Your Technical Knowledge: Understand your familiarity with the methodologies and technologies used in wind resource assessments.
2. Gauge Your Practical Experience: Evaluate whether you have hands-on experience in conducting these assessments and can navigate the challenges they present.
3. Determine Your Analytical Skills: See how well you can analyze data and make informed decisions based on your assessments.
4. Evaluate Problem-Solving Abilities: Assess your capability to troubleshoot and provide solutions when faced with data anomalies or assessment barriers.

How to Approach Your Answer

When crafting your response, aim to outline a step-by-step process that demonstrates a comprehensive understanding of all facets involved in a wind resource assessment. Your answer should reflect knowledge of industry standards, practical experience, and the ability to integrate technology and analysis in your assessment process. Here's how you might structure your approach:

1. Preliminary Site Evaluation: Mention how you'd start with a desktop study using available online resources (wind maps, satellite images) to understand the site's potential without immediate fieldwork.
2. Anemometry Campaign: Discuss the importance of installing meteorological masts or using remote sensing devices (like SODAR or LIDAR) to collect wind data (speed, direction, turbulence) over a significant period, typically 1-2 years.
3. Data Analysis: Explain how you'd analyze the collected data, focusing on wind speed frequency distributions, wind direction, seasonal variations, and the impact of the terrain on the wind flow.
4. Use of Software Tools: Detail the software tools (e.g., WAsP, WindPRO, OpenWind) you'd use for modeling the wind flow and predicting the site's energy yield.
5. Environmental and Social Impact Consideration: Highlight the importance of assessing the environmental and social impacts, including potential effects on local wildlife and community acceptance.
6. Financial Feasibility Analysis: Briefly touch on conducting a preliminary financial assessment based on the estimated energy production and project costs.

Example Responses Relevant to Wind Energy Engineer

"I would begin with a preliminary site evaluation to identify the site's potential using existing wind data and geographic information. Following this, I'd plan an anemometry campaign, selecting the optimal locations for installing meteorological masts to gather site-specific wind data for at least a year. This data collection is critical for understanding local wind patterns and their implications for wind farm design.

Next, I'd analyze the collected data using statistical methods to characterize the wind resource, including mean wind speed, wind direction distribution, and turbulence intensity. This analysis would be supplemented with advanced software tools like WindPRO or WAsP for wind flow modeling and energy yield prediction, ensuring we consider the terrain's influence on wind behavior.

Additionally, I recognize the importance of environmental and social impact assessments. It's crucial to evaluate potential impacts on local wildlife and habitat, as well as to engage with the local community to understand and mitigate any concerns.

Finally, combining the technical assessment with a preliminary financial analysis, considering capital and operational costs against predicted energy yield, would allow us to gauge the project's viability."

Tips for Success

• Be Specific: Use technical language appropriate for a wind energy engineer and provide specific examples from your experience, if possible.
