Access to account-level energy usage data empowers individual consumers to save money and shrink their carbon footprint. And with third parties like CUB, access to such data can do even more. Illinois’ data access framework, while protecting the privacy of customers, makes interval energy usage data available by time and location, in half-hour increments, daily, over a series of years and by local zip codes.
These datasets have fueled numerous papers by CUB’s research department, including one analysis that found in a test year 97 percent of ComEd customers could have saved money on a utility real-time pricing program, without changing behavior. Compared to the flat rate that most consumers pay now, the real-time pricing model showed an average annual savings of $86.63 for ComEd customers.
In recent years, CUB’s data team has also shown how electric vehicles could help control power grid costs and has raised the concern that low-income households pay more than their fair share for electricity.
