Brief

The webinar, a presentation on July 30, 2026 from NARUC with Berkeley Lab speakers Guillermo Pereira, Greg Leventis, and Miguel Heleno, explained how Distribution System Planning (DSP) and capacity expansion modeling can streamline interconnection. In this tutorial-style briefing presenters showed how modeling identifies targeted upgrades, offered coordination practices (process alignment and data sharing), and recommended concrete steps utilities and regulators can take to integrate DSP with interconnection workflows.

Why it matters

Webinar published July 30, 2026 on NARUC’s YouTube channel featured Berkeley Lab speakers Guillermo Pereira, Greg Leventis, and Miguel Heleno (video: https://www.youtube.com/watch?v=STWE91KG51s).

Key details

  • Distribution System Planning (DSP), including capacity expansion modeling, was presented as a tool to support more efficient interconnection by identifying where distribution upgrades can be deferred or targeted to increase hosting capacity and reduce upgrade costs.
  • The session shared example practices for coordinating interconnection and DSP and provided concrete actions participants can take to start or improve coordination of DSP with interconnection-related upgrades (process alignment, data sharing, and using modeled scenarios to prioritize upgrades).
Source evidence

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.
