FROM:
Mike Tietz –Technical Services Superintendent
MEETING DATE:
March 14, 2023
AGENDA ITEM NUMBER:
6.1h
SUBJECT:
Staff Update
ACTION REQUESTED:
None
DISCUSSION:
• In March, the locators processed 82 locate tickets. These consisted of 66 normal tickets,
6 updated tickets, 1 cancellation, 2 meets, 4 non-excavation, and 3 boundary surveys.
This resulted in a 10.8% increase in tickets from the previous month and is a 7.9%
decrease from the prior February.
• Electrical technicians completed 184 service order tasks, updated the power bill,
addressed customer meter issues and any off-peak concerns.
• On February 23, staff ran generators #1, #2 & #3. Staff has been working on repairing
our aftercooler issue on Engine #4 as time allows. They have disassembled the
aftercooler and have been testing tubes for leaks. This is a very tedious process as there
are 640 tubes that need to be checked individually. We found a total of 61 tubes that
were leaking, and I am in the process of procuring plugs to install in the tubes to
complete repairs.
• Great River Energy (GRE) is doing some work on their 69kV bus along with some relay
work that necessitated us moving all the load from our Station 14 Bank 4 substation
over to Bank 3 and de-energizing our Bank 4 transformer until March 15. Technical
services staff will have some SCADA checkout work to do when GRE completes their
work. This will involve updating and testing the functionality of some remote terminal
units that have been remapped to our relay.
• I have been involved with several projects recently such as the Voltus generation
contracts, Minnesota Municipal Power Association’s solar interconnection project, and
the Grid Resilience and Innovation Partnerships grant application. I have also been
reviewing the Advanced Metering Infrastructure master services agreement that we
received back from Core & Main.
