Table 1. At-a-glance overall status report (see risks and mitigation section for detail). Red = cost and schedule exceeds baseline and is non-recoverable; Yellow = currently overspent or currently behind schedule but recoverable to baseline end date and total cost; Green =meeting or exceeding the baseline expectations for cost or schedule.
The scope remains fixed: Modernize the unit through replacement of turbine, generator, field poles, GSU, governor and control system. The budget for the project including all trailing costs with plant and program closeout and drawings into Sept 2020 is $9.5M.
Unit 4’s construction began Sept 2018, with outage thru Aug 2019, extended to 9/30/2019 due to wicket gate delay.

•All cables and wires installed, pulled into place and being terminated,
•Line boring complete, field poles installed and wedged, stator halves in place and spliced, field poles installed
•Hudson Bay completed ducting insulation, Concrete Cutters completed U3 & U2 vault work
Upcoming Activities
•Materials and equipment orders continue for unit install work, receiving new parts and materials, almost complete
•Continued progress in assembly, parts and pieces received from vendors and are at plant
•Assembly of equipment and materials is occurring
•Wicket gates install complete, last 10 field poles installed and wedged, oil and water line install and prep in progress
•Hudson Bay final banding of ducting TBD after unit completion

•SCADA PLC design and Bailey Retirement design transmittal forthcoming. Work to be completed after Unit 4 is online but beforeend Oct 2019.
Risks and Mitigation Strategies:
•Issues with Wagstaff and quality of wicket gates and potential delays is continually being monitored. Completion dates are set,pending actual delivery of gates. GOC modified, and commissioning dates communicated to internal and external stakeholders.Continued updates to Steering Committee are occurring. Gates received and installed. Project schedule and GOC updated. Tofurther mitigate this project delay, a one week (compressed) commissioning schedule is being implemented by the Project Teamto be able to release the unit to Operations for commercial production in advance of the Sept 30 GOC expiration. COMPLETED
•Following feedback from crews, adjusted GSU commissioning in Unit 4 schedule to allow for more time between GSU 2commissioning and Unit 4 commissioning. - COMPLETED
•Continue to work with Engineers and Crews to review and discuss the planned activities at weekly construction meetings,prepare work authorizations and procurements in advance of need, check all parts/equipment deliveries for properpart/size/damage, etc before installation dates. ON-GOING

Table 1. At-a-glance overall status report (see risks and mitigation section for detail). Red = cost and schedule exceeds baseline and is non-recoverable; Yellow = currently overspent or currently behind schedule but recoverable to baseline end date and total cost; Green =meeting or exceeding the baseline expectations for cost or schedule.
The scope remains fixed: Modernize the unit through replacement of turbine, generator, field poles, GSU, governor and control system.
The budget for the project remains at $8.2M. Project was under budget due to progress payments on turbine bumped into 2017
Unit 4’s construction began Sept 2018
