Solar Decommissioning Bond Requirements in New Jersey
New Jersey’s S3399 introduces decommissioning bond requirements for commercial solar facilities. A decommissioning bond is a financial guarantee that funds will be available to properly remove and recycle a solar installation at end of life — even if the owner defaults or the operator no longer exists. Here is what commercial operators need to know.
When bonds are required
Decommissioning bonds are typically required for commercial solar installations before permits are issued. Facilities most commonly required to post bonds include:
- Utility-scale and ground-mount solar installations
- Commercial rooftop systems above a certain capacity threshold
- Solar installations on agricultural or leased land
- Projects financed through municipal or public programs
Smaller commercial rooftop installations and residential systems are often exempt, but operators should confirm requirements with their local jurisdiction before assuming an exemption applies.
How bond amounts are calculated
Bond amounts are typically calculated as a percentage of the estimated total decommissioning cost — commonly 125% of the estimated cost, providing a buffer against cost increases over the system’s lifetime. Decommissioning cost estimates must account for:
- Panel removal labor and equipment
- Racking and hardware removal
- Electrical disconnection and safe-off
- Transport to certified recycling facility
- Recycling fees
- Site restoration to pre-installation condition
For reference, total decommissioning costs typically range from $15,000 to $50,000 per megawatt depending on system complexity, site conditions, and current recycling costs. A 250kW system with an estimated decommissioning cost of $30,000 would require a bond of approximately $37,500 at 125%.
Professional engineer certification
Most jurisdictions require that decommissioning cost estimates be certified by a licensed professional engineer. PE certification requirements typically include:
- Site inspection and system documentation review
- Itemized cost estimate covering all removal and restoration components
- Certification that the estimate reflects current market rates
- Periodic review and update — typically every five years
- Signature and seal on all submitted documentation
Working with your decommissioning contractor
An accurate bond calculation depends on a realistic decommissioning cost estimate. Blue Flag Solar works with commercial operators and their engineers to provide detailed removal scope and pricing that supports the bonding process. Getting the estimate right at the outset avoids the cost of re-bonding when estimates prove too low.
Frequently asked questions
Does every commercial solar installation in NJ require a decommissioning bond?
Not every installation — bond requirements vary by system size, installation type, and local jurisdiction. Utility-scale and ground-mount systems are most commonly required to post bonds. Confirm requirements with your local permitting authority before assuming an exemption applies.
How often does a decommissioning bond amount need to be updated?
Most jurisdictions require bond amounts to be reviewed and updated every five years to reflect current decommissioning costs. Your PE-certified cost estimate should be refreshed on the same schedule.
