  • Establishing performance and design criteria
  • Performing a technical review of VSC technology in comparison to LCC technology
  • Providing environmental licensing support
  • Providing project management support, including cost estimating, scheduling, quality assurance, and risk management
  • Synchronous compensator facility, including performing a technology review of available technologies and determining machine parameters, ratings, and performance requirements
  • Overseeing development of technical specifications for both LCC and VSC options
  • Performing technical bid evaluations of the tenders and providing technical contract negotiation assistance
  • Providing design review services
  • Project management support including quality management and implementation planning
  • Teshmont is also providing engineering services for the ground electrodes for the Bipole III system. Teshmont’s scope of work includes site selection, preliminary design, and detailed design.
