Hutchinson Utilities to advertise bids for Plant 1 transformer; staff outlines 1- and 2-transformer options

Summary

Commission approved advertising for bids for the Plant 1 substation transformer, with staff recommending options to cover long lead times. Estimates presented: roughly $10 million for a 1-transformer/2-breaker design vs. $18 million for a 2-transformer/4-breaker design; transmission working group recommended paring back the larger design.

The commission authorized staff to advertise bids for the Plant 1 substation transformer at the Jan. 28 meeting, citing long lead times (staff estimated approximately three years for transformer procurement). Staff explained two procurement/design options: a 1-transformer/2-breaker design estimated at about $10 million and a 2-transformer/4-breaker design estimated at about $18 million. The larger design raised both distribution and transmission cost-allocation concerns and the transmission working group advised paring it down.

Staff said the alternate-bid approach preserves options on award, allowing the commission to accept one or two transformers or different sizes when bids return, but the plan is more likely to move forward with a single-transformer design in the near term. The commission approved the advertisement for bids by voice vote so procurement can begin and allow for long lead-time equipment ordering as project planning continues.

Commissioners asked about design drivers and timing; staff said the contract award is expected in April and the final design will be set then. No individual vote tallies were recorded beyond the voice approval at the meeting.
