This is what I got from Enmax:
Good morning Raied,
Thank you for contacting ENMAX. My name is Nancy and I appreciate the opportunity to respond to your billing inquiry.
Please accept our apologies for the delay in response. We have been experiencing higher than normal volumes which have impacted our service levels.
Raied, ENMAX meters measure wattage usage.
Should you have any further questions or concerns, please do not hesitate to reply to this email and I will be happy to assist you. Alternatively, you may contact our Customer Care Centre at 310-2010 (Toll Free in Alberta) Monday to Friday 8:00 am to 8:00 pm and Saturday 8:00 am to 4:30 pm.
Thank you for granting ENMAX the opportunity to be of service for you.
Yours truly,
Nancy C.
