Congratulations Wellesley! 

When you reduce your electricity use during peak summer hours, everyone benefits with lower electric rates and a cleaner environment, because the WMLP can reduce its use of low-efficiency electricity generating plants which operate only during peak periods.

Did you know that 30 percent of your electric bill is directly related to the amount of electricity Wellesley uses for just one hour during the entire year? That one hour, the peak demand hour, occurred at 6PM on July 20 in 2022. The graph below shows how GHG emissions and costs skyrocketed during the summer peak. Wellesley's electric demand on that date and the drop due to voluntary demand reduction resulted in savings to WMLP of approximately $67,000.
