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.

Equity, Affordability and Access in the Clean Energy Transition

As states turn toward a clean energy transition, affordability and access must be an integral part of the discussion. Otherwise, equity may be compromised. Black and Brown communities experience higher energy rates and higher rates of power disconnection due to many overlapping historical and modern factors such as housing injustice, racial segregation, and wealth disparities. On average, Black and Hispanic households are at least two times more likely to have their utility service, a critical basic need, disconnected than White households. Further, to cut down on their cost of energy, some households may resort to adjusting temperatures to unhealthy levels, resulting in negative health impacts. This further contributes to disparate health impacts experienced by Black and Brown communities. Equity and affordability on regulators’ radar In Massachusetts, the Department of Public Utilities recently determined that total energy burdens should be no more than six percent of shelter costs. In addition, the DPU is seeking further stakeholder comments on where target levels (below six percent) should be set when designing tiered discount rates that benefit the highest number of customers. The DPU is also seeking comments on whether revenue shortfalls from discounted rates should be recovered statewide instead of utility-wide, and whether all stakeholders should contribute to recovery of the revenue shortfall. Through these investigations, the DPU is for the first time working to increase energy affordability for Massachusetts ratepayers. Energy regulatory commissions around the country are, like Massachusetts, beginning to address issues of equity, affordability and access. As states strive to meet their climate goals in the coming years by transitioning to an electric-powered grid, energy affordability is more important than ever from an environmental justice and equity perspective. Currently, the federal government provides funding to states to support low-income ratepayers. Low Income Home Energy Assistance Program (LIHEAP) provides federal funding assistance to reduce the costs associated with home energy bills, energy crises, weatherization, and minor energy-related home repairs. States receive the funding and distribute it based on their own policies. States and individual utility companies also provide various payment assistance programs. Although helpful, such programs do not fully address the energy burdens faced by many households. Further, many people are not enrolled in any kind of low-income assistance program because they do not self-identify as low-income, therefore marketing for financial support programs needs to be improved to increase enrollment. Many middle-income people are also struggling to afford high energy bills that are taking a large chunk out of their income, but they do not qualify under the income thresholds for low-income assistance programs. More data, language access will help State energy regulators should collect more data about the usage behaviors for different households and demographics to help people determine the programs that could relieve some of the burden of their energy bill. Regulators should also look to ensure low-income customers have access to and can benefit from clean energy infrastructure. Energy regulators should consider ways to leverage funding from the Inflation Reduction Act and other sources to provide heat pump rebates to low- and moderate-income homes. They should also consider novel approaches, such as percentage of income payment plans. This rate structure avoids leaving median-income individuals without support. As state energy regulators navigate the clean energy transition and equity issues, they must also consider language access, which. ensures that everyone can receive information on how to access rate support programs. State energy regulators should consider implementing current EPA guidance on best practices for language access, which includes translating information into every language spoken by at least five percent of people in the relevant area. State energy regulators should err on the side of over-inclusivity in translation to non-English languages. Environmental justice must be considered in every aspect of the energy transition. From access to translated information to access to heat in the middle of winter, no one should be left behind.

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.
