The National Association of Regulatory Utility Commissioners (NARUC) has launched an initiative to support a cohort of state public utility commissions to better understand utility distributed energy resource (DER) interconnection practices and advance solutions that improve transparency, speed, affordability, security, and reliability. Participating commissions will learn practical information and help inform templates, frameworks, and model language developed by NARUC and LBNL for jurisdictions to adapt to their specific circumstances.
The cohort meets monthly, typically on the last Wednesday of the month, from 3:00 p.m. to 4:30 p.m. ET through September. Individual meeting information, including topics, registration links, and presentation materials (when available) can be found below. Participation in cohort meetings is limited to NARUC member commissions (commissioners and staff). Non-member registrations will be cancelled.
Berkeley Lab provides informational webinars for Energy Innovator Fellows at utilities, state agencies, and Tribes, with funding from the U.S. Department of Energy. View the recordings and presentation slides from past webinars.
Please reach out to Jeff Loiter at jloiter@naruc.org or Sydney Forrester at spforrester@lbl.gov with questions.
- Kick Off Meeting, March 5, 2026: The initial meeting of the cohort included a presentation by Hawaiian Electric about their Customer Energy Resources program and interconnection policies; an overview of the planned cohort activities by Berkeley Labs; and a questionnaire to help set the direction for subsequent cohort meetings.
- Interconnection Queues, Timelines, and Costs - Data Transparency, Wednesday, May 27, 2026: Explore how utility commissions can create a foundation for managing high interconnection costs by collecting data to better understand interconnection-related costs for distribution upgrades and how they impact interconnection customers, as well as other data that support implementation of interconnection solutions.
- Managing Interconnection Costs Part 1 - Cost Allocation, Tuesday, June 23, 2026: Provide information on how cost allocation approaches affect interconnection costs and timelines, present on various methodologies, and hear from states with experience implementing new cost allocation approaches.
- Managing Interconnection Costs Part 2 - Distribution System Planning and Capacity Expansion Modeling, Wednesday, July 29, 2026: This webinar will provide information on how DSP (including capacity expansion modeling) can support efficient interconnection, share example practices for coordinating interconnection and DSP, and identify concrete actions participants can take to start or improve coordination of DSP with interconnection-related upgrades. Berkeley Lab speakers: Guillermo Pereira, Greg Leventis, and Miguel Heleno.
- DER Interconnection Model Guidelines and Flexible Interconnection, Wednesday, August 26, 2026: This webinar will provide information on how DSP (including capacity expansion modeling) can support efficient interconnection, example practices for coordinating interconnection and DSP, and concrete actions participants can take to start or improve coordination of DSP with interconnection-related upgrades. Register now.
- Interconnection Data Template and Guidelines, Wednesday, September 23, 2026: Tee up and get feedback on data reporting template and guidelines document resulting from cohort and LBNL work that participants and non-participants can benefit from. Participants will also have the opportunity to share thoughts about additional needs and resources and submit any outstanding questions and topics for further consideration by NARUC and Lab partners.
