After learning a few months ago from this group that Eversource had Time of Use (TOU) rates available in Eastern MA, I applied to Eversource to switch to TOU for my EV charging service. I have a separate service for charging, so by charging at night I will have little or no usage during the peak daytime hours. The meter was (finally!) installed today. So I am looking forward to seeing a savings of roughly $10/month on my costs for EV charging. It seemed to take an inordinately long time to switch my meter. To make a long story short, after a month's wait I made several phone calls. Finally I encountered a customer service person who acted proactively and was able to speak with the right person to expedite the request. As it was, it was nearly 7 weeks from request to installation. What would be nice is if I could log into the Eversource website and see my usage. I know that the meter can deliver the data, and I know that some other utilities offer that service, but I can't find any indication of that on the Eversource web site. Otherwise I will just have to take data off the meter and runs the numbers (if and when I want to). The trick now will be to maximize the savings by minimizing the energy usage during peak periods. For me, the main risk will be preheating or precooling the car.
