These excerpts from the American Planning Association’s Planning Advisory Service memo touch on hidden long-term costs of industrial-scale solar projects. Many solar developers try to reduce their security deposit for decommissioning by the amount of salvage value they say they’ll get from recycling, but there is little salvage value for used panels, even now. And the amount they do give deposit may not be enough to cover all the future costs of removing the hardware and restoring the land. Such gaps put local governments at risk for paying the cost of decommissioning themselves.
- Decommissioning can cost millions in today’s dollars. The industry strongly asserts that there is a significant salvage value to the solar arrays, but there may or may not be a market to salvage the equipment when removed. Further, the feasibility of realizing salvage value may depend on who removes the equipment—the operator, the tenant, or the landowner (who may not be the same parties as during construction)—as well as when it is removed.
- Providing for adequate security to ensure that financial resources are available to remove the equipment is a significant challenge. Cash escrow is the most reliable security for a locality but is the most expensive for the industry and potentially a financial deal breaker. Insurance bonds or letters of credit seem to be the most acceptable forms of security but can be difficult to enforce as a practical matter. The impact of inflation over decades is difficult to calculate; therefore, the posted financial security to ensure a proper decommissioning should be reevaluated periodically—usually every five years or so. The worst possible outcome for a community (and a farmer or landowner) would be an abandoned utility-scale solar facility with no resources available to pay for its removal.

If the solar energy farm is inactive, completely or substantially discontinuing the delivery of electricity to an electrical grid for a continuous 30 day period, excepting for items outside of control of the Project, or longer as approved by the Zoning Administrator in consultation with other agencies with submittal of requested documentation from the applicant or project owner, as needed; it shall be considered abandoned. (…) The applicant or current project owner shall remove the facilities (“decommissioning”) within six (6) months of receipt of notice from the County. If the facility is not removed within the specified time after the County Notice, the County may cause the removal of the solar energy farm with costs being borne by the Project Owner.
(…) Decommissioning activities are expected to take between 6–8 months.

The process for determining whether a solar project has been “abandoned” are more complicated and time-consuming than one might think. The project owner is supposed to notify the County if the project is being shut down, but the details on how the county or town enforces that notification are generally missing. If officials must take legal action against the developer and/or property owner, the process to even begin decommissioning can take much longer than anticipated. And while this agreement for Louisa County considers the project to be abandoned after 6 months, other Virginia counties allow projects to remain inactive for up to 24 months (2 years) before beginning the process to enforce the decommissioning agreement.
Potential questions to consider:
- What are the penalties for a solar company if it does not notify officials that its solar project is being abandoned or closed?
- What is the county or town process for “causing the removal of the solar energy farm” if a project owner doesn’t begin the work in a timely fashion or fails to respond to county notifications?
- How long does the county or town estimate it would take to complete the legal action needed to compel compliance?
- What legal recourse does the county or town have if the developer fails to remove all project materials within the time stated in the agreement?

Every large-scale solar project requires that project developers provide a decommissioning agreement in writing to county and town officials and to the public. The details are very important because they constitute the sole legal commitment about what the solar developer is or is not required to do to remove the installation. Each solar project is slightly different and zoning rules vary from county to county, especially with regard to industrial-scale solar. Each decommissioning document needs to be reviewed carefully to make sure the process and end result is in the best interests of county and town taxpayers.
The most important question of all for any aspect of the decommissioning process is whether the details will be put in writing in a form that is legally binding and enforceable by the county or town.
For instance, how is the decision to decommission a large-scale solar project made? How will the land be restored and will all equipment and hardware be completely removed? What happens to the used solar panels if the manufacturers (most of whom are in China) refuse to take them back? And who pays in the end?
Details for the first four items are from documentation provided for the 2016/2017 hearing on the Belcher II Solar Project in Louisa County, while decommissioning costs are from the APA’s Planning Advisory Memo:
