About PlotWatt

Nearly 10 years ago PlotWatt’s founder and CEO Luke Fishback found himself baffled by his electric bill…and he’s a rocket scientist. That frustration led to a simple question: “What if my electric bill was itemized by appliance?”

His answer was PlotWatt, a team of mathematicians, scientists and software developers who write software and create algorithms to take data from smart meters and translate it into what appliances are doing. PlotWatt’s energy analysts take this data, pair it with location-based usage information, and uncover the energy-saving opportunities that offer the biggest return. PlotWatt then generates customized recommendations to help employees reduce usage through small changes to their daily routines.

PlotWatt works with quick service restaurant chains and small- and medium-sized businesses. These actionable recommendations help drive operational efficiencies and save an average of 10% on energy bills per month, while also alerting customers if equipment is not functioning properly.

Project Description

PlotWatt is deploying their energy efficiency solution at quick-service and casual restaurant chains, as well as other small- and medium-sized businesses throughout Hawaii and the Philippines. Their energy monitors, installed in each location, feed real-time electricity data back to PlotWatt where their algorithms analyze that data and provide restaurant employees with actionable tips on how to better run their equipment and reduce energy use. Their solution monitors HVAC systems, walk-in coolers and freezers, and other critical equipment, and alerts customers in real time if something is wrong, i.e. the HVAC system is not functioning properly or the freezer door was accidentally left open when employees left for the night. In Hawaii, PlotWatt is working with partners such as Hawaiian Electric and Hawaii Energy, Hawaii’s energy efficiency utility, to identify people who would benefit from PlotWatt’s solution. Targeting restaurants is particularly important in Hawaii, where these small businesses tend to operate on thin margins and utility bills represent a significant proportion of monthly operating expenses.
