Solar stormwater control lacking

Stormwater control and excess water runoff from utility-scale solar projects is not a new problem. And it is not unique to Virginia. This article describes significant water runoff problems from a relatively small 24-acre solar project in near East Lyme, Connecticut.

Problems included the clear-cutting of trees from the project area; excess silting of streams and kill-offs of fresh-water trout; and the lack of response from solar developers responsible for installing the project.

More industrial-scale solar projects in Pittsylvania

Residents in Pittsylvania County are pushing back after the Board of Supervisors greenlighted three more industrial-scale solar projects across the county. One of these is the Firefly project, under development by the Canadian firm Recurrent Solar and slated for a 3,700-acre tract east of Danville.

Residents concerned after Pittsylvania County approves locations for solar farms

The Planning Commission will hold another hearing on solar projects in general on Tuesday, 1 March 2022, at 7:00 p.m.

Representatives of Recurrent Solar have told residents that, once constructed, solar projects produce no pollution. “Once constructed” is important to note, since all large solar projects in Virginia to date have produced excessive amounts of stormwater overflow and runoff, damaging neighboring properties, streams, and watersheds. (A large-scale solar project in Louisa County, for instance, has caused significant runoff that has routinely flooded neighboring properties.)

In addition, the representatives have told residents that vegetation can grow under the solar panels. However, the American Planning Association warns that the significant re-grading and removal of topsoil and vegetation has long-term negative impacts because it changes the natural characteristics of the soil, making it difficult to restore the land to its previous condition.

In all, developers are currently building four large-scale solar projects in Pittsylvania County, with at least 18 more approved and planned for future construction.

Utility-scale solar & the Chesapeake Bay

One concern of moving toward utility-scale solar that is not often discussed is its potential damage to the ecological health of the Chesapeake Bay. Sixty percent of Virginia’s land mass is in the Chesapeake Bay watershed, meaning that anything going into those rivers and streams is eventually deposited in the Bay. The challenge with utility-scale solar is that stormwater, run-off, and erosion have proven to be a significant concern in every large-scale solar project constructed in Virginia so far. (This television report about Louisa County is just one example.)

The Chesapeake Bay Foundation has long worked to improve the ecological health of the Bay, including focusing on the damage caused by excess sedimentation flows into the bay. (Visit its website to learn more about how you can help!)

This map shows the counties in the Bay’s watershed and how much utility-scale solar is projected for each one, based on what solar developers have filed with electricity grid regulators. In all, this represents over 220,000 acres that will be covered by impermeable solar panels, which will worsen the stormwater and run-off problems already experienced to date.
