The proposed FY 2027 capital budget allocates $57 million to Grid Mod. Staff said upgrades would be based on customer demand rather than systematic buildout, and approximately $80 million in initial debt financing is planned for fall 2026. Staff said the proposed budget would support a revised "when and where" rollout approach and purchase long-lead substation transformers needed for planned rebuilds. The total estimate cited in discussion was $375 million to $450 million. Staff stated that Grid Mod and fiber construction were separated after anticipated shared-work savings did not materialize; differing skills, costs, and project sequencing caused delays. The five-year capital plan includes intent to advance two undergrounding utility districts, with preliminary design, easement review, district formation, advisory review, and eventual Council approval anticipated.

Staff proposed prioritizing 60kV subtransmission reconductoring, conversion of legacy 4kV systems, substation reconstruction, and feeder ties while pacing 12kV distribution upgrades to customer electrification, permit activity, and AMI data. Staff said 4kV conversions were planned for completion by FY2028; substation work could extend through FY2034 because transformer lead times were four to five years.
