How Salvage Value Now Affects Maryland Solar Decommissioning Bonds

Maryland's solar decommissioning rules are making one thing clear: end-of-life value is no longer just a financial assumption. It directly affects the bond a project owner is required to post.

Under Maryland Public Utilities Article § 7-218, the owner of a covered solar energy generating station must enter into a decommissioning agreement with the Maryland Public Service Commission, post a surety bond for not more than 125% of the estimated future cost of decommissioning the project and related infrastructure, less any salvage value, and complete a bond true-up every five years. That makes salvage value a critical number, and one that needs to reflect fair market value throughout the project’s lifespan

If salvage value is overstated, the decommissioning bond may run too low. If salvage value is understated, the bond may run higher than it needs to, costing not-inconsequential basis points on larger projects and across portfolios. Either way, the project owner, lender, insurer, landowner, and regulator rely on a number that needs support.

What is a Maryland solar decommissioning bond?

A solar decommissioning bond is a financial assurance mechanism designed to keep money available to remove a solar project and restore the site at the end of the project's life or in the event of abandonment.

Maryland's Power Plant Research Program (PPRP) states that solar facilities operating under CPCN authority must have a robust decommissioning plan so future landowners can use the land without being hindered by its former use as a solar generation site, and so decommissioning costs do not fall on the state, county, or municipal authority.

A decommissioning plan should identify the responsible parties, timeframes, sequence of activities, estimated costs, dismantling requirements, legal disposal of components, and restoration of the affected land. Maryland's guidance also says the cost estimate should be prepared by a knowledgeable third party and should address the safe removal and proper disposal of project components, including solar panels, cables, wires, steel racks, and above- and below-ground foundations.

In plain terms, the bond exists so the public, the county, and the landowner do not get left with the bill if a project is abandoned or reaches the end of its useful life.

Where salvage value enters the bond calculation

The phrase "less any salvage value" is the important part.

Maryland's statute allows salvage value to reduce the amount that must be bonded. The recoverable value of project equipment can therefore affect the size of the financial assurance requirement.

A simple way to think about it is:

Gross decommissioning cost minus supported salvage value equals net decommissioning cost. The bond is then tied to that net cost. As of the current draft, Maryland's decommissioning agreement sets the initial bond value at 125% of the estimated net cost of decommissioning in Year 5, including inflation, or the estimated startup decommissioning costs, including inflation, whichever is greater. Salvage value is not a footnote. It can materially change the bond amount.

Why unsupported salvage value creates risk

Salvage value sounds straightforward, but it is easy to get wrong.

A solar project may hold recoverable value in panels, steel racking, aluminium frames, copper wiring, inverters, transformers, and other equipment. Some materials may carry scrap value. Some equipment may carry resale value. Some panels may suit refurbishment or secondary-market reuse. Other components may hold little value once removal, transportation, testing, recycling, or disposal costs are included.

Maryland's PPRP guidance is clear that if salvage value is included in the decommissioning cost estimate, the applicant must provide reliable documentation to support the estimate.

That is the business issue.

A salvage value estimate built on a generic assumption may not hold up when the bond is reviewed, updated, financed, insured, or challenged. The number needs a basis. It should tie to actual equipment, age, condition, marketability, recycling pathways, resale options, transportation costs, and likely end-of-life disposition.

What Maryland's 2026 draft decommissioning agreement says about salvage value

In April 2026, the Maryland PSC opened a request for comments on decommissioning plan requirements (Case No. 9873) and linked to a PPRP draft decommissioning agreement and a decommissioning cost estimation workbook.

The draft materials give useful insight into where Maryland's process is heading. They contemplate crediting revenue from salvage, recycling, or resale of solar modules and commodities such as steel, aluminium, and copper to offset decommissioning costs. As of the current draft, they also limit the salvage credit to 85% as a conservatism adjustment for market variability over time.

The draft also treats solar panel recycling and resale as emerging markets, noting there is not yet enough data to establish a standard salvage value per panel. For panel salvage revenue, the project owner must provide documentation from a specific solar panel recycling or resale facility.

That is a meaningful point for asset owners and developers. Maryland is moving away from panel salvage values pulled from a broad market average. The owner needs documentation tied to a real recycling or resale pathway.

Because the agreement and workbook remain in draft and out for public comment, treat the specific figures above as subject to change until Maryland finalizes them.

The bond true-up makes this a recurring issue

Maryland's statute requires a bond true-up every five years. PPRP guidance reinforces the point: within five years after a CPCN is granted, and every five years after that, solar facility owners must revise the decommissioning plan, cost estimate, and financial assurance mechanism. Those updates should adjust for inflation, reflect the ongoing evolution of solar panel recycling and resale markets, and incorporate any other necessary changes.

The salvage value question does not get answered once. It comes back repeatedly over the life of the project.

A project that is ten years old may show a very different recovery profile than it did at approval. Panel condition may change. Secondary-market demand may change. Recycling capacity may change. Commodity prices may change. Transportation costs may change. Decommissioning labor costs may change.

For owners, the five-year update is more than an administrative requirement. It is a recurring valuation event.

Why this matters for the asset owners

For asset owners, salvage value is where compliance and asset value meet. A solar project is more than a collection of panels in the ground. It is a portfolio of physical components with different end-of-life outcomes. Some components may be reused. Some may be resold. Some may be recycled. Some may become disposal liabilities.

Maryland's decommissioning framework makes that distinction financially important. Documented recoverable value may help reduce the net decommissioning cost. Undocumented value may not be accepted.

That creates a direct incentive to understand what the asset is worth before decommissioning becomes urgent.

Why this matters for the lenders

For lenders, the decommissioning bond is part of the project's risk profile.

A bond set too low because salvage value was overstated may leave the project carrying an unfunded end-of-life liability. A bond set too high because salvage value went unrecognized may tie up capital in financial assurance that the project does not need.

Both outcomes matter in underwriting.

The lender needs confidence that the decommissioning estimate is credible, the salvage assumptions are documented, and the financial assurance amount reflects a realistic view of the asset's future recoverable value.

Why this matters for the insurers

For insurers, salvage value affects more than decommissioning. It can influence how the project is valued, how equipment is documented, how claims are evaluated, and how end-of-life or post-loss recovery is understood.

A solar project with a documented equipment inventory, defensible residual value, and credible recycling or resale pathways is easier to underwrite than a project that leans on unsupported assumptions.

This matters most when values are challenged. If a project owner, broker, or insurer needs to defend a number, the methodology matters as much as the final figure.

What a defensible salvage value should include:

A stronger salvage value estimate should include the following:

• an inventory of major project components
• module type, age, condition, and expected remaining useful life
• inverter, transformer, racking, wiring, and metal recovery assumptions
• current and projected commodity value
• resale, refurbishment, recycling, and disposal pathways
• transportation distance to identified facilities
• tipping fees, handling fees, and testing costs
• documentation from credible recyclers, resellers, or recovery partners
• clear assumptions that owners can update every five years

Maryland's draft cost estimation workbook asks project owners to identify the facilities to be used for disposal, recycling, salvage, or resale and to provide estimated mileage from the project site to each facility. It also ties panel resale value to documentation from a credible reseller or recycler. That is the level of evidence the market should expect.

The compliance standard is getting higher

Maryland solar decommissioning bonds are no longer just about estimating removal costs.

They are about proving the relationship between gross decommissioning cost, recoverable asset value, and financial assurance. The salvage value used in the bond calculation needs to be more than a hopeful estimate. It should rest on market evidence, facility documentation, and a clear methodology.

For developers, lenders, insurers, and asset owners, the takeaway is simple: salvage value can reduce the decommissioning bond, but only when the number can be defended.
