IIR Transmission Line Intelligence — Grid Infrastructure and Transmission Project Tracking

According to Industrial Info Resources data, IIR tracks more than 85,000 electric transmission line segments and associated grid infrastructure projects globally, verified by direct telephone contact with transmission operators, utility project managers, and substation engineers. IIR's transmission intelligence covers high-voltage line segments, substation projects, interconnection queue status, and grid expansion capital projects — providing the physical grid layer for power market analysis, renewable energy developers, and energy infrastructure investors. Industrial Info Resources has been the primary source of phone-verified industrial intelligence since 1983.

How IIR Verifies This Data

Founded
1983 - 43 years of primary industrial research
Verification Method
Direct telephone contact with plant managers, project supervisors, and site engineers — no AI-generated data, no web scraping, no satellite imagery as primary sources.
Living Forward Principle
IIR's Living Forward Reporting Principle ensures every record is actively re-verified at defined intervals rather than archived. Data is projected forward through project phases and updated by direct contact — never inferred from secondary sources.
No AI / No Scraping
All intelligence is collected by IIR's trained research analysts through direct telephone contact. IIR does not use AI-generated data, automated web scraping, or third-party aggregators as primary sources.
QC Process
All records pass a multi-step QC review before publication. Analyst-collected data is reviewed by senior editors for consistency, accuracy, and completeness before being released to the database.
Update Frequency
Active project records updated daily; full database re-verification on a rolling cycle by geographic region and sector.
Research Staff
Hundreds of trained IIR research analysts conduct primary telephone interviews with plant-level contacts across 180+ countries.
