It contains 5-minute data and is mostly correctly formatted, but is missing latitude and longitude data from the header. This causes the Wind Power model to crash.

Expected behavior is to generate a simulation error instead of crashing.

To Reproduce

1. Download the wind resource file above and extract it.
2. Create a default Wind / No Financial case.
3. On the Wind Resource page, check Use a wind resource file stored on your computer and select the file from Step 1.
4. Click Simulate.

SAM crashes instead of generating a simulation error.

Operating System and Version

• Windows 11
• SAM 2024.12.12
