Developers and town spar over escrow, decommissioning and financial safeguards for battery projects

At the Grand Island workshop, financial safeguards for battery storage projects—escrow, bonds, letters of credit and decommissioning cost assumptions—proved a central technical discussion.

Staff presented a draft requiring an escrow of 1% of project cost. Developers proposed a flat escrow of $28,000 with a replenishment trigger. When participants discussed project economics, Speaker 3 and others estimated a 5-megawatt facility could cost about $8–9 million to build; under a 1% escrow that equates to roughly $80,000–$90,000.

Participants proposed compromise options. Some suggested a midrange flat amount (for example, $50,000) with a replenishment requirement so the town would not need to pursue small top-ups while preserving an enforceable fund for decommissioning or site restoration. Speakers also discussed the relative merits of letters of credit (the state’s preferred instrument) versus bonds; both require periodic renewal and periodic reassessment of removal costs.

Speakers said salvage value and recycling prospects (batteries and equipment) would be considered when setting bond amounts; developers noted some removal costs can be covered in the original purchase price or through manufacturer provisions. No formal fiscal policy was adopted; staff will reflect financial feedback in the next draft of the law.

Next steps: revise escrow/decommissioning language to specify calculation method, replenishment triggers and acceptable security instruments (letter of credit or bond) for planning-board review.
