City staff present solar‑generation cost models; council asks for deeper analysis as risks, tax‑credit timing and bond exposure surface
Summary
City staff told the North Platte council that an owned utility solar field would cost an estimated 7.8¢/kWh in the model used and could add roughly $1.2 million in costs under a 10% mix; council members raised concerns about construction risk, tax‑credit timing and bonding capacity and asked staff for more detailed scenarios.
City staff presented a preliminary analysis of municipal solar generation options during the Nov. 18 North Platte City Council meeting and recommended further study rather than immediate action.
Staff summarized the city’s current purchased‑power exposure (about $18 million in purchased power last fiscal year versus roughly $31.7 million in utility revenue) and explained modeling assumptions for adding owned solar generation. The presentation estimated an all‑in delivered cost for owned solar of roughly 7.8¢ per kilowatt hour and, under a scenario where 10% of power came from solar and the remainder stayed with the city’s wholesale supplier, modeled a roughly $1.2 million increase in power costs in the near term versus present costs.
Councilmembers and staff discussed financing options (mix of bonds and reserves), lifecycle and decommissioning costs, construction‑cost overrun risks, the potential (but uncertain) value of federal tax credits, and whether the city’s bonding capacity or exposure justified a municipal build. Several council members said they were cautious about committing city bonding capacity and noted that the wholesale provider (Nebraska Public Power District) had said it could be more economical for a customer to pay a premium than for the utility to fund a separate solar field.
Staff recommended additional analysis, including: more granular capital‑cost and O&M assumptions, sensitivity testing around tax credits and construction delays, options to procure power from third parties rather than own generation outright, and an estimate of how different solar mixes would affect typical monthly bills. Council asked staff to return with the requested scenarios and stressed that staff should include decommissioning/removal cost assumptions in any future model. No formal action or vote was taken.
