en.Wedoany.com Reported - A study by the University of Rhode Island shows that the state's 119 ground-mounted solar projects with a capacity of 1 megawatt or more are highly concentrated in specific narrow corridors within Kent County and Providence County, with a median distance of just 1,531 meters between projects. This high concentration has led to the rapid saturation of substation capacity and driven up land lease costs and grid connection fees for subsequent projects.
Early developers may have concentrated in these areas due to favorable local zoning policies or open terrain. The study notes that clustering multiple multi-megawatt projects within a 1 to 5 kilometer radius quickly exhausts available feeder and substation capacity, leading to a significant increase in grid connection costs. Meanwhile, intensified competition for limited land parcels drives up lease rates, compressing project profit margins.
When solar projects cluster in a specific area, their impact on local communities is amplified: instead of individual towns facing isolated projects, entire multi-town regions witness large tracts of land converted into solar infrastructure. The study warns that this concentration provides stronger grounds for local opposition groups, triggering stricter local ordinances, moratoriums, and complex permitting hurdles. Since clusters often cross municipal boundaries, traditional single-town zoning reviews struggle to address the demands of regional expansion.
The study shows that early market opportunities in established solar hotspots are now facing obstacles. To avoid local grid saturation and permitting resistance, developers need to look beyond individual municipal zoning maps and adopt refined regional planning, targeting non-clustered areas and anticipating where the next wave of regional development corridors will form before local grid congestion occurs.
