Lime Wind is a 3000kW wind project, interconnected with the Idaho Power 12.47kV distribution system, located on BLM land east of Lime, Oregon. The project consists of six 500kW refurbished wind generators, 690V-12.47kV step-up transformers, 12.47kV collection system, automatic switched capacitor bank for reactive power control, and interconnection to Idaho Power.
TriAxis Engineering provided conceptual design support for the Interconnection Application, review of the System Impact Study and Facilities Studies, review and technical support during negotiation of the Interconnection Agreement, materials specification (transformer, cable, capacitor bank, sectionalizing cabinets), design review, medium voltage collection system design, low voltage interconnection design, programming for the capacitor bank control, and other support from project inception through commissioning.

PINE TREE WIND FARM PHASE V Kern County, California Los Angeles Department of Water and Power (LADWP)
The design criteria utilized for the design of phases I through IV was verified and modified for the addition of ten wind turbine generators to the existing Pine Tree Wind Farm. The project included updating/revising the current padmount transformer specifications to meet the LADWP and turbine manu-factureer design specifications. To incorporate new pad mounted transformers project drawings were updated to include the new primary cable connections, secondary cable connections, conduit entrances to the wind turbine power modules, and foundations.
Design of the collection system included providing and updating design base files and coordination of the electrical design with the civil/site grading plans. Collection system studies included analysis of the current grounding transformer design to determine that the exsisting grounding transformer placement and sizing were adequate for the 10 WTG addition. The existing soil thermal resistivity analysis was reviewed and updated also.
New SCADA fiber optic systems were designed to tie into the exiting fiber optic system. New fiber runs were placed in cable trenches installed for the addition. Estimated design cost was $97,500.
