Sense exposed a billing error

Estimated Savings:

We installed Sense in the middle of an issue with the well pump trigger which had broken in an on position. Cost us thousands, and Sense helped us narrow down the problem. But more recently we had a surprising surge in electricity consumption that would have gone unchecked without Sense. With two years of data in hand I could show the utility that most months Sense and their readings and estimates were very similar. Just 3-5% off. And then it jumped to 600-740% off. Without the data from Sense we would have had a harder time making a case for an adjustment. They knocked 10,000 kwh off our recent bill. I noticed a similar pattern a year ago that I will be addressing next with them.
