- Reviewed 500 and 765 kV transmission plans on behalf of a confidential utility client. The work involved innovative reviews of existing transmission expansion plans.
Important aspects of the study were determining the range of impacts from large increased renewable coal generation retirements.
- Developed transmission plans to serve major new wind farms: Transmission plans were developed and evaluated to meet 500-1,500 MW of new wind generation proposed for eastern San
Diego County. The studies considered steady-state, voltage, short circuit, and stability conditions and requirements. Various alternatives were ranked base on technical merit, approximate cost, and
general environmental impact.
- Transmission analysis for wind generation: Performed a review of the bulk power transmission system in New Mexico in regard to the potential development of new generation, both
