Interconnection
Interconnection refers to the process and infrastructure required to connect a power generation facility to the electrical transmission or distribution grid, enabling the delivery of electricity to end users. This complex process involves technical studies, regulatory approvals, and physical construction of transmission lines, substations, and transformers.
The interconnection queue represents the backlog of projects awaiting connection, which can span several years in high-demand regions. Studies assess system impact, including short-circuit analysis, stability studies, and power flow modeling.
Interconnection costs can represent 10-30% of total project capital expenditure, with significant regional variations based on grid infrastructure maturity. Modern interconnection frameworks incorporate renewable energy integration requirements, including dynamic models for inverter-based resources and advanced power electronics.
The process has evolved from first-come, first-served systems to more sophisticated cluster-based approaches that optimize grid utilization and reduce study costs through coordinated development.
Technical Details

- •Queue backlogs: 2-5+ years in constrained regions (California, Texas, Northeast US)
- •Cost components: Transmission upgrades, interconnection facilities, system studies
- •Technical requirements: IEEE standards, regional grid codes, NERC reliability criteria
- •Modern approaches: Cluster studies, dynamic modeling, advanced inverter requirements
Why It Matters
Interconnection represents the most significant bottleneck in renewable energy deployment. In Tera Intelligence Platform's Power Grid Map and Asset Intelligence modules, interconnection data helps developers prioritize queue positions, assess timeline risks, and optimize project development strategies. Investors use interconnection analysis to evaluate project timelines and capital cost risks, while grid operators monitor queue dynamics to plan infrastructure investments. The platform's comprehensive mapping of 45M+ grid infrastructure assets and detailed interconnection intelligence enables stakeholders to identify optimal connection points and understand regional grid capacity constraints across global electricity markets.
