| Abstract |
These slides summarize and explain empirical data on interconnection timelines and costs for distributed energy projects connected to U.S. utility distribution systems. The study explores how interconnection metrics vary across states, project sizes, technology types, and over time to indicate progress toward simple, fast, and affordable interconnection. Data encompasses 188 utilities in 24 states. Project types include biomass/biofuels, coal, hydropower, natural gas/oil, solar, storage, wind, hybrid, and other technologies. |
| Notes |
A webinar discussing this research was held on May 27, 2026. The presentation slides can be viewed here. Lawrence Berkeley National Laboratory's Distributed Energy Projects Interconnection Dashboard harnesses data from across the country on applications, timelines and costs for all types of distributed generation and storage connected to utility distribution systems. The interactive tool allows users to build custom queries, apply filters, aggregate metrics, and visualize results in multiple formats. Users may also download visualizations and associated aggregated data. |
