Ratepayer Lab

The one-stop-shop for the reports, articles, and resources that consumer advocates need to advance affordability at their state public utility commissions.

Ratepayer Lab is RMI’s technical assistance platform for state consumer advocate offices to support their work in making our electricity system more affordable for residential utility customers.

Our services are available to all NASUCA members and affiliates.

Through Ratepayer Lab, RMI provides services such as modeling, analysis, drafting of regulatory comments, development and sponsorship of testimony, participation as subject-matter experts in workshops or other proceedings, and the creation of reusable analytic tools that strengthen affordability arguments inside and outside of commission proceedings. This support is designed to empower consumer advocates to shape decisions that reduce household energy burdens in a durable fashion.

Ratepayer Lab helps consumer advocates advance affordability policies in each state through:

  • ROE reforms
  • Securitization
  • Implementing or fixing multi-year rate plans
  • Better planning
  • Large load tariffs
  • Performance-based regulation
  • Fair cost allocation
  • Improved bill assistance
  • Low-income discount rates
  • Low-income energy efficiency
  • Percentage of income payment plans
  • Disconnection protections
  • Arrearage management plans

Ratepayer Lab can also connect consumer advocates with other experts in the field who can help design new policies or evaluate existing programs to ensure that ratepayers are protected and connected to safe, affordable electricity.

Use the menu above to review our range of services; tools to support data-driven affordability work; and reports and articles to get up-to-speed on the most impactful affordability topics today.

If you would like to speak with an RMI expert about any of the services or resources here, contact Joe Daniel (JDaniel@rmi.org).

Services

RMI builds and maintains tools to track and address the affordability challenges facing utility customers. RMI’s tools have been designed to assist in policy discussions and inform policy design. They have been used in a variety of settings for policy discussions and adapted for expert testimony in proceedings across the country.

RMI’s original research has been collected into foundational reports that push the state of the art of regulatory reform and grid innovation. Leveraging these reports can resolve both emergent and regularly occurring challenges facing the electricity system.

RMI conducts cutting edge research that informs the policy design, implementation, and priorities of decision makers. Our library of resources includes research commissioned by regulatory commissions, state energy offices, and consumer advocates.

RMI experts regularly attend PUC workshops to help inform and support a robust record to shape affordability discussions. RMI also has on-staff master facilitators who can lead convenings.

RMI experts can help prepare discovery, comments, and even expert testimony that can be filed in the next resource plan, fuel docket, or rate case. RMI keeps and maintains a clearinghouse of discovery, comments, and commission rulings on key topics that can often be leveraged in contested proceedings in other jurisdictions.
