What happened
A brush fire broke out along the perimeter fencing of East Windsor Solar One, a solar generation site in East Windsor, Connecticut, after an equipment failure. Fire crews found a roughly 100 by 50 foot area of dried grass and shrubs ablaze near the fence line, with flames spreading rapidly due to high winds. The fire was contained quickly by the local fire department and no injuries were reported. A separate complaint about sparking wires in the same area was later attributed to grid-side equipment operated by Eversource Energy rather than the generation equipment owned by NextEra Energy.
Following the incident, the site remained offline for an extended period while a state utility regulator reviewed maintenance practices and equipment condition. The regulator found the utility's maintenance to be reasonable but ordered further technical studies, including a power quality assessment and equipment inspection, to be completed more than a year after the fire.
Contributing factors
Dried vegetation adjacent to the perimeter fencing at East Windsor Solar One, high wind conditions that accelerated fire spread, and an underlying equipment failure whose specific technical cause was not detailed in public reporting. A separate sparking complaint was linked to grid-side equipment operated by Eversource Energy rather than the generation assets owned by NextEra Energy.
Lessons learned
- Dried vegetation next to perimeter fencing can fuel rapid fire spread in high winds, so operators should clear grass and shrubs before dry seasons.
- Grid and generation equipment ownership must be clearly marked so fault investigations do not mix separate systems.
- Privately owned solar sites need defined post-incident inspection powers or regulators cannot act promptly after fires.
