Renewable Energy Interconnection & Gen-Tie Design

Specialized gen-tie and collection line design for utility-scale renewable energy projects, including solar photovoltaic, battery energy storage systems (BESS), and wind generation facilities.

Services include:
- Overhead gen-tie design from 34.5 kV to 500 kV
- Underground-to-overhead transition and riser structure design
- Double-circuit collection line engineering
- Design criteria development (NESC 2023, utility-specific standards)
- Conductor selection — ampacity and surface gradient calculations
- Routing assessments with multiple route option evaluation
- PLS-CADD modeling integrating LiDAR, ALTA survey, and grading data
- Crossing exhibits for pipelines, railways, roadways, and transmission lines
- Coordination with utilities, EPCs, and permitting agencies
- Water crossing drawings for USACE permit applications
- FAA pre-screening evaluations
- 10%, 30%, 60%, 90%, and IFC design packages

Project experience includes gen-tie designs for solar and BESS facilities across multiple states and voltage classes from 34.5 kV to 500 kV, with no limitation on facility capacity.
