Marshfield utilities debate how M1 revenues should feed maintenance fund as policy updates are drafted

The Marshfield Utilities Commission continued a detailed review of proposed changes to the utility’s cash-reserve and investment policies at its meeting, focusing on how revenue from the M1 power plant is allocated into a dedicated M1 maintenance fund and how that routing could affect year-end allocations to other utility funds.

Commissioners and staff spent the bulk of the discussion parsing language changes in a draft cash-reserve and investment policy, the proposed creation of clearer liquid and investment fund buckets (checking, savings, money-market/LGIP versus CDs and government securities), and an approach to reallocating interest earnings at year-end. Staff presented the redlined draft and emphasized that the revisions are intended to consolidate overlapping language and build flexibility into operating and investment accounts. “I think that’s the gist of the changes that we’re presenting tonight for discussion,” Nick, a utility staff member, said.

Why it matters: The discussion centered on the M1 maintenance fund, which staff said currently holds roughly $4,000,000 and has a target of about $7,000,000. Commissioners raised concerns that the current operational flow — where monthly M1 revenues are credited back to customers under Public Service Commission (PSC) rules while staff concurrently earmark matching cash into the maintenance fund — can make the utility’s cash-flow picture look weaker during the year and reduce the pool of excess cash available for other priorities at the year-end allocation.

Key points from the discussion

- Policy revisions: Staff proposed moving overlapping language from the investment policy into the cash-reserve policy, explicitly naming money-market accounts and LGIP as liquid accounts, and adding an “overall target of 300 days” phrasing to broaden the reserve metric beyond strict cash balances.

- Fund structure: The draft distinguishes between liquid funds (checking, savings, money market, LGIP) used for near-term obligations (debt service, customer refunds) and less-liquid investments (CDs, government securities) intended to maximize yield consistent with the policy’s risk-minimization goal. Staff explained that leftover cash after placing amounts into CDs would be parked in LGIP or money-market accounts to maintain liquidity.

- Interest and allocation: The draft calls for interest earnings to be included in the annual allocation process rather than left in a single fund; staff said interest can be reallocated at year-end based on the commission’s priorities so that, for example, interest credited to the future-projects fund could be moved if the commission chooses.

- M1 revenue mechanics and the maintenance fund: Staff and commissioners repeatedly returned to how M1 revenues flow. Staff explained that monthly capacity and market revenues received from MISO are reduced in the utility’s power-supply-cost calculation and thus passed back to customers per PSC rules; separately, the commission-directed accounting entry moves an equal cash amount into the M1 maintenance fund to build reserves for potential plant repairs or rebuilds. A staff member summarized the tension: the same operating activity produces both a customer credit and, by commission action, a transfer into a restricted maintenance fund.

- Quantities discussed in the meeting: Staff said the M1 maintenance fund holds about $4,000,000 today and that the target used for planning is roughly $7,000,000. The commission also discussed a projected capacity-related commitment of roughly $1,300,000 in the coming year and noted that the utility’s net M1-related revenue in 2024 was $408,000 (staff said that figure excludes interest). Participants referenced recent depreciation and capital numbers presented in the capital budget process — the electric utility’s annual depreciation figure was discussed in the meeting and cited as roughly $33,300,000 in the budget context and $807,000 in depreciation-related figures tied to particular years — and several commissioners asked staff to present a more detailed cash-status showing the various inputs (customer credits, interest earnings, depreciation, capacity payments) that feed the maintenance fund.

Commissioners’ direction and next steps

Commissioners did not adopt the draft policy at the meeting. Instead they asked staff for one more month of cash-status detail in the proposed new format so the commission could see how the draft policy would translate to actual numbers. Several commissioners warned that moving to an annual-allocation pool could allow future commissions to under-allocate to the maintenance fund in some years; others emphasized the flexibility the draft policy provides to reassign interest earnings or to liquidate CDs early (with the understood cost of lost interest). Staff confirmed that the commission may change the policy at any point. “No. We can change the policy at any point,” a staff member said when asked about the ability to alter the approach mid-cycle.

Ending

The commission paused action to allow staff to produce a cash-status report that matches the proposed policy presentation. Commissioners said they expect to revisit the draft in the commission’s first-quarter allocation discussion (staff identified that timing as the early part of the next calendar year) and that the body could amend the policy sooner if needed. The item moved to further review rather than a final vote.
