Carroll County forwards jail solar proposal to Delegation after committee's financial analysis

The Carroll County Board of Commissioners voted 3-0 on March 6 to send a proposal for a roughly 100 kilowatt alternating-current solar array at the county jail to the county Delegation for further review. Facilities Director Bob Murray and Solar Exploratory Committee member Wharton Sinkler presented a written analysis that compared three bids and outlined financing scenarios.

Murray described the technical and financial assumptions underlying the analysis, including that the array would generate about 23%–28% of the jail's roughly 750,000 kWh annual usage, occupy under a half-acre south of the jail, and route power to existing meters. The three firms that responded to the request for proposals were Barrington Power, New England Clean Energy and ReVision Energy; the committee recommended Barrington Power.

The financial model the committee presented assumed an 80% loan from the Community Development Finance Authority (CDFA), an initial county outlay of about 20% of the project cost, and a federal investment tax credit equal to roughly 30% of the purchase price delivered via the Elective Pay mechanism. Because the committee was told county borrowers may not qualify for a previously cited 2.75% loan, the presentation used a 4.25% assumed interest rate for its conservative scenario. Under that model, the analysis projects that once the loan's balloon payment is made the county would save roughly $30,000 a year and could avoid about $1 million in energy costs over a 40-year assumed system life.

The package notes additional assumptions: renewable energy certificate (REC) revenue of about $0.03 per kWh, 2% annual electric-price inflation, 0.5% annual panel performance degradation and an allowance for inverter replacement every 10–15 years. The presentation also cautioned that 5% of funding must be spent by July 4, 2026, and identified next steps as Delegation review by end of March, a loan application and an initial county investment of roughly $98,000.

Commissioner Harold B. Parker moved to forward the proposal to the Delegation; Clerk Gene Chandler seconded and the motion passed unanimously. No contract award or financing agreement was finalized at the meeting; commissioners said the Delegation will review the package and that additional clarifications on loan terms and vendor selection will follow.

The board thanked the volunteer members of the Solar Exploratory Committee and noted the county will return with additional documentation if the Delegation requests it.

Ending — The action sends the project to the next step in the county approval process; the Delegation will review the detailed bids and financing assumptions before any contract is signed or funds are committed.
