Texas manufacturing client — predominant use study shows 78% of their electric consumption is for the manufacturing process. Submitted the study + Form 01-339 and the utility still won't apply the exemption. They keep pointing to "insufficient documentation." What am I missing?

Manufacturing exemption — utility refuses to acknowledge certificate
Texas requires the study be performed by a licensed engineer and signed/sealed. If yours wasn't, that's almost certainly the issue. Also the utility needs Form AP-215 (exemption affidavit) filed separately from 01-339. Both forms together.
On the NC predominant-use study — the cost varies wildly. I've seen quotes from $800 to $4,500. The study pays for itself almost every time in manufacturing settings.
