If you would like more information about UEE products and services, we'd love to hear from you.
The project scope for UEE consisted of the design, manufacturing and commissioning of the 25kV interconnection substation, interconnection protection and control system, 5kV generator switchgear, interconnection and generator protection system, plc based turbine/generator control system, human machine interface system, intake power control system and balance of plant/station service subsystems.
The engineering package included complete drawings, testing plans, commissioning plans, quality assurance documentation, production testing reports, operations manuals, maintenance manuals, installation cable and interconnection schedules.
Site services included all equipment testing, protection verification testing, and control system verification testing. UEE also provided operator training and configuration of the remote monitoring and control station.
Due to location and design factors, Tyson Creek will have the highest capacity factor (average megawatts delivered versus total ability of the plant) of any hydro project tendered to date. It will operate at capacity from 70 to 80% of the time, versus the norm of 40 to 60%. The site features a natural 875 meter drop, which will give it the highest head of any run-of -the-river plant in North America, enabling it to efficiently generate energy year round.
UEE provided all of the electrical engineering and design services, working in conjunction with the owner's engineers.
The plant has been awarded an Electricity Purchase Agreement (EPA) by BC Hydro. The contract is for a 40 year period. The plant is expected to have a peak capacity of 9 megawatts and will on average provide power to 5500 homes.
