Bringing consistency, financial protection and site restoration into focus
As more utility-scale solar projects come online across the country, questions about what happens at the end of a project’s life continue to surface in county meetings and kitchen table conversations alike.
What happens if a project shuts down early?
Who pays to remove the panels?
Will the land be restored?
North Carolina has responded to those concerns with one of the most comprehensive statewide solar decommissioning frameworks in the country. Rather than relying on a patchwork of county ordinances, the state now administers a uniform system that establishes clear requirements for registration, financial assurance, removal of equipment and site restoration.
For landowners, local governments and developers, that clarity matters.
A Statewide Standard, Not a Patchwork
Effective April 1, 2025, the North Carolina Department of Environmental Quality (DEQ) began administering updated decommissioning rules for utility-scale solar projects.
The law applies to new solar projects with a nameplate capacity of two megawatts or greater, including projects with battery storage. Project owners must register with DEQ and submit:
- A detailed decommissioning plan
- A third-party cost estimate for removal and restoration
- Proof of financial assurance
- Required registration fees
Projects are categorized as either existing or new based on the date of their Certificate of Public Convenience and Necessity application, ensuring clarity in how the rules apply.
This statewide framework replaced what had previously been a county-by-county approach, creating consistency for landowners and clearer expectations for developers.
Detailed Decommissioning Requirements
North Carolina’s rules require more than simply removing panels.
When operations cease, project owners must remove:
- Solar panels
- Foundations
- Underground cables
- Fencing
- Battery systems
- All associated system components
The land must be restored to pre-project condition or to another condition agreed upon by the landowner and project owner. That provision preserves flexibility for agricultural reuse or other future plans.
The rules also require appropriate handling of hazardous and non-hazardous materials, including identification of any associated per- and polyfluoroalkyl substances in the decommissioning plan. Materials must be reused or recycled where possible.
In short, the obligation extends beyond removal. It includes responsible disposal and site restoration.
Financial Assurance That Protects Landowners
One of the most significant components of North Carolina’s framework is its financial assurance requirement.
Before operating, project owners must demonstrate the financial capacity to cover decommissioning costs. Acceptable mechanisms include:
- Corporate guarantees
- Financial tests
- Insurance
- Letters of credit
- Surety bonds
- Trust funds
- Or combinations of these
DEQ provides approved language for these mechanisms and verifies compliance.
Importantly:
- Financial assurance and cost estimates must be updated every five years.
- If ownership changes, the new owner must provide an executed financial assurance mechanism within 30 days.
- The previous owner remains responsible until formally released by DEQ.
Cost estimates must reflect third-party removal, transportation, recycling and disposal costs. While salvage value can be factored in, financial assurance cannot drop below a minimum threshold beginning 20 years after operations commence or five years before the end of the initial power purchase agreement, whichever comes first.
That safeguard ensures funds remain available even late in a project’s life.
The Role of Local Governments
North Carolina’s framework establishes minimum statewide standards, but it does not prevent counties from imposing more stringent conditions through local ordinances or contracts.
Local governments may:
- Require stronger decommissioning provisions
- Impose additional financial assurance requirements
- Accept local financial assurance in place of DEQ assurance
This balance creates statewide consistency while preserving local authority.
It also provides modest, stable property tax revenues to counties. Under North Carolina law, solar equipment qualifies for an 80% exemption, meaning local revenue is tied primarily to land and non-exempt property.
Agricultural and Environmental Considerations
Decommissioning requirements explicitly address proper waste handling and land restoration. The goal is to return the site to its pre-project condition unless otherwise agreed upon.
For agricultural landowners, that provision is especially important. It supports the ability to resume farming or ranching activities after a project concludes.
North Carolina has also encouraged responsible land use practices during operations, including agrivoltaic approaches and pollinator habitat establishment, though those practices are separate from the decommissioning rules themselves.
Why This Framework Matters
Opposition to solar development often centers on long-term uncertainty. Concerns about abandoned equipment or unreclaimed land can dominate public meetings.
North Carolina’s approach addresses those concerns directly by:
- Requiring formal registration
- Mandating detailed decommissioning plans
- Requiring verified financial assurance
- Establishing periodic updates
- Providing enforcement authority through DEQ
By replacing a fragmented county system with a uniform statewide program, the state has created clarity for landowners, local officials and developers alike.
For landowners who are approached by developers, understanding a state’s decommissioning framework is critical. Strong end-of-life standards do not guarantee a good contract, but they do provide a regulatory backstop that reduces uncertainty.
North Carolina’s model demonstrates that solar development and responsible end-of-life planning are not mutually exclusive. With mandatory registration, enforceable financial assurance and clear restoration standards, the state has established a structure that protects private property and community interests while allowing projects to move forward under defined rules.
For landowners across the country, these kinds of frameworks are worth understanding.
