Thank you for the opportunity to resubmit our manuscript (Manuscript # D-21-04525R1; Title: Novel method for acquiring rigorous temperature response functions for electricity demand at the regional scale) to your journal. We are still in the process of preparing our manuscript for resubmission and need additional time for preparation. In addition, the time needed for a professional English proofreading service for this paper was longer than we have expected. Because we want to ensure that we have fully addressed all of your concerns, I am writing to respectfully inquire as to whether you would consider extending our resubmission deadline to October 16, 2021. My apologies for bothering you again.

Thank you again for the opportunity to submit, and I appreciate any assistance that you can provide.

Sincerely yours,
