What is a Utility Rate Case


What is a Utility Rate Case?

A utility is a business providing a public service — natural gas, electricity, water — subject to special government rules. Natural gas and electricity utilities are granted monopolies to distribute energy in their service areas, and the amount of profit they are allowed to earn is regulated by the state.

Traditionally, utilities’ profits are a percentage of money invested in the distribution part of the system – how it delivers gas or electricity to buildings and provide service to the customer (end-user). A utility files a rate case to ask state regulators for permission to invest new money — and raise customers’ gas or electricity rates to recoup that investment. In Illinois, the regulator in charge of this decision is the Illinois Commerce Commission (ICC).

The ICC’s mission is to balance the interests of consumers and public utilities to ensure adequate, efficient, reliable, safe, and least-cost utility services, while promoting the development of an effectively competitive energy supplier market.

Questions that arise in rate cases include concepts open to interpretation: What is the “public interest”? What investments are “prudent and reasonable”? What is the meaning of Reliable? Safe? Efficient? Equitable?

New visions

Traditional rate cases center around a utility’s planned investment, but new visions for our current energy system consider other values: meeting state climate goals; addressing the health impacts of pollution in communities; looking at whether the quality of service is the same across neighborhoods; analyzing whether all customers can access clean energy.

Participating in rate cases

There are various ways to be part of the decision-making process at the ICC, but participation as an official “party” to cases is the only way to influence requests filed by utilities formally. Only testimony from parties to the case can be on the record, and only material officially on the record can be considered in decision-making. Still, building relationships with ICC commissioners and participating in stakeholder forums can be very influential when policies are being developed.

Community testimony

In 2022, Environmental Defense Fund pioneered a new technique: highlighting the critical, real-life experiences of community members as official, expert testimony in a rate case. Commissioners heard directly from community members about the effects of policy decisions — less reliable service (longer, more frequent outages) and poorer air quality — in their neighborhoods, where residents are more likely to be low-income, Black, and brown people. This evidence of inequality made a difference: The Illinois Commerce Commission stated that EDF and the Citizens Utility Board raised its awareness that environmental justice communities experience longer and more frequent power outages than wealthier communities, while also having fewer resources to withstand and recover from disruptions.

Illinois Rate Cases 2023

In January 2023, all three of Illinois’ gas distribution utilities filed rate cases with the ICC. At the same time, the state’s two electric utilities filed multi-year rate plans. Together, these five rate hikes would cost Illinois ratepayers an extra $1.8 billion every year.

The burden is on the utilities to convince the ICC that their requests meet a “just and reasonable” standard. The ICC’s final decisions are due in December 2023.

Fairness and equity goals

Throughout 2023 partners developed data and testimony to demonstrate that these large proposed rate hikes – especially those that will encourage fossil fuel use – are not in the best interest of customers, are inequitable, and do not align with state climate goals. Our goal, instead, is to accelerate an affordable clean energy transition, including directing investments to communities that have historically borne the highest burdens from the energy system, while enjoying the least benefits from it.

Rate case decisions must be made based on information or evidence introduced on the record by parties to the case through filings, discovery, and testimony.

Understanding energy behaviors for a more equitable future

Dr. Destenie Nock published a new study based on research in Chicago showing that low-income households turn on their cooling systems in hot weather three degrees later than higher income households, but they turn on heat in cold weather six degrees earlier than high income households, whether because of poor insulation or other reasons. “This work highlights the challenges low-income communities face. Not only are they at higher risk in the summer, but in the winter they have to spend a lot more money to protect their pipes from freezing,” noted Nock. “The financial stress of heating homes in winter can also lead to broader inequities.” Dr. Nock's data can be used to shape policies that address systemic inequities, guide investments in infrastructure, and help improve living conditions for energy-insecure and vulnerable households. Dr. Nock has provided expert testimony in Illinois rate case proceedings.

EDF’s new equity map shows state efforts to make the energy transition fairer for all

Across the U.S. states are passing laws that will ensure greater equity as we transition to a clean energy system. EDF has developed an interactive map – based on our new report, the State Climate Equity Survey – that documents states’ efforts to make their energy transition more equitable and healthier. Our new map identifies which states require, allow, or promote consideration of equity and environmental justice in agency decision-making and budget-setting.

Massachusetts outlines new strategy for getting customers and utilities off gas

After more than three years of considering the future of the natural gas industry in Massachusetts and what role it can play in the state's efforts to significantly reduce its greenhouse gas emissions, the state's Department of Public Utilities issued an order meant to signal to gas utilities that it won't be business as usual going forward.
