Why Nassau County is High risk
Score calculated from four factors: power infrastructure, water capacity, land availability, and current exposure. Nassau's score reflects the NextNRG announcement — the 12-month moratorium adopted June 8, 2026 reduces the county's near-term risk profile significantly for the next year.
Limited in-county generation, but adjacent counties have significant capacity. NextNRG's original pitch included an on-site 200 MW microgrid for exactly this reason.
St. Johns River Water Management District — mixed urban/rural, moderate capacity. One of the healthier water profiles among at-risk counties.
Rural with significant open land. NextNRG holds a lease option on 1,600 acres plus potential access to 6,000 more.
NextNRG's September 2025 announcement — later walked back to "solar farm" — triggered the moratorium discussion.
The facts, as filed.
A pre-emptive moratorium, and a company that changed its story.
At its April 13, 2026 meeting, the Nassau County Board of County Commissioners directed County Attorney Denise May to draft an ordinance placing a 12-month moratorium on new data center development within unincorporated Nassau County. Commission Chair Alyson McCullough (R-District 4) has been the public face of the push. In an April 14 news release, the county stated that there are no active or pending applications for data center development in unincorporated Nassau County and framed the moratorium as a proactive measure to give staff time to develop appropriate standards before any developer files under the existing zoning code.
The current zoning code has no standards specific to hyperscale data centers. Under existing rules, a developer could potentially file and proceed under the general industrial designations. The moratorium pauses acceptance and processing of new data center applications for twelve months — time the county is using to draft a land-development-code update with data-center-specific standards around water, power, air, noise, setbacks, and disclosure.
The process ran three steps: initial discussion of the draft ordinance on April 27, 2026, a first public hearing on May 11, 2026, and a second public hearing plus the final vote on June 8, 2026, all at 96135 Nassau Place in Yulee. Commissioners adopted Ordinance No. 2026-044 unanimously at the June 8 hearing.
Nassau is not the first U.S. jurisdiction to try this — at least six states, from New York to Georgia, have proposed moratoriums on new data center construction as a way to buy time for regulation. Florida has passed statewide data center legislation that took effect July 1, 2026, but that law primarily addresses utility tariffs and confidentiality. Local siting, water, and land-use decisions remain the county's responsibility.
In a September 22, 2025 news release, Miami-based NextNRG (NASDAQ: NXXT) announced it had secured a long-term lease option on 1,600 acres in Nassau County from timber and real estate company Rayonier. The release described plans for a 200-megawatt smart microgrid on roughly 1,200 acres, with the remaining 400 acres described as "ideal" for hyperscale data center development. The release also cited potential access to an additional 6,000 acres for future expansion and positioned the site near Jacksonville International Airport as attractive for AI and cloud infrastructure growth.
Six months later, Nassau County officials said they had no information about the project — no rezoning request, no site plan, no contact from the company despite attempts to reach out. On April 6, 2026, the county issued a statement to that effect. NextNRG did not respond to reporter inquiries in early April.
Following commissioner action on the moratorium, NextNRG founder and CEO Michael D. Farkas — who also founded electric-vehicle charging company Blink Charging — gave an interview to First Coast News clarifying the company's position. Farkas said the original intent was a solar-energy project: solar panels, battery storage, and sales to local utility JEA. He acknowledged the company had considered a data center when the solar project ran into difficulties but said a data center is not the direction NextNRG intends to pursue. JEA confirmed NextNRG has reached out but said no agreements have been made.
The credibility question for residents and commissioners is which framing reflects the company's actual intent. The original release was public, specific, and described the site in explicitly data-center terms. The walk-back came after a moratorium was already on the table. No application of any kind — for a data center, a solar farm, or anything else — had been filed with Nassau County as of the June 8, 2026 moratorium adoption — which is precisely why the county could freeze the ground without disrupting anyone already in the queue.
How we got here.
For Nassau County residents.
What the moratorium actually does
The moratorium freezes the acceptance and processing of new data center applications in unincorporated Nassau County for up to twelve months from June 8, 2026. It is not a permanent ban and does not retroactively cancel approved projects (there were none to cancel). Its practical purpose is to give county staff time to draft land-development-code standards specific to data centers — rules around water draw, noise, air emissions from backup generators, setbacks from residences and schools, and disclosure requirements for developers. Without those standards, a project filed today could potentially proceed under generic industrial zoning rules that were not designed for hyperscale facilities.
What the moratorium does not do
Ordinance No. 2026-044 applies to unincorporated Nassau County only. Incorporated areas such as Fernandina Beach, Callahan, and Hilliard make their own land-use decisions. It does not affect solar farms, microgrids, or other non-data-center uses of the NextNRG site. If NextNRG's walk-back is taken at face value — a solar project serving JEA — the moratorium has no direct effect on that plan. And it expires: without permanent land-development-code standards adopted before it lapses, the county returns to the same general industrial rules that prompted it.
How to weigh the NextNRG walk-back
Residents and commissioners are left to decide how much weight to give NextNRG's revised framing. Arguments for accepting it: the original announcement used hedging language ("ideal for"), no application has been filed, and the CEO has now stated publicly that data centers are not the company's business. Arguments for skepticism: the September 2025 release was specific about the 400 acres, fiber latency, and hyperscale fit; the walk-back came only after a moratorium was on the table; and NextNRG was publicly unreachable for six months until coverage escalated. The moratorium resolves the asymmetry by making the question moot for twelve months.
Where residents have the most leverage
The moratorium fight is over — it passed. The leverage now sits with the Fact-Finding Committee, which entered its drafting phase on June 29 with a 30-day window to produce recommendations. Those recommendations go to the Board of County Commissioners, which must hold public hearings before adopting any permanent regulations. That is where the rules that outlast the freeze get written, and it is the input window that still matters. Meeting materials, workshop video, and a digital portal for submitting testimony are posted on the county's data center page.
