Belmont Light has put together easy-to-use calculators to give you real numbers for how you might benefit from Time of Use Rates. All you’ll need to use these calculators is your Calculator ID Number.

Due to data security issues, Belmont Light will provide a randomized, individual “Calculator ID Number” that represents your electric meter number. To get your unique Calculator ID Number, email timeofuse@belmontlight.com with your name and address.


Usage & Rate Comparison Calculator

As we strive to give you everything necessary for a successful Time of Use Rates Pilot Program experience, we are excited to announce a new rate simulation tool that allows pilot participants to compare their electricity costs under Time of Use Rates to what their costs would have been under the standard residential Rate A.

This new tool comes out of our partnership with RenwAI, a software provider serving data-driven utilities like Belmont Light. We picture it as a first version of a brand new software tool. As it stands now, the tool provides a static display of a one-month comparison, but RenwAI and Belmont Light picture a more comprehensive, dynamic tool to come in the future. Over the coming months, we’ll be continually adding new features, additional comparisons, and enhancing the design.
