The marquee development reshaping Portland, TN is the new 638,000-square-foot Shoals Technologies Group manufacturing campus at 1500 Shoals Way, which opened with a ribbon-cutting on May 18, 2026. The hometown solar- and energy-infrastructure company (NASDAQ: SHLS) consolidated three existing Tennessee facilities into one centralized 'mega facility,' backed by a $30 million initial investment and a commitment of up to $80 million over five years, reinforcing Portland's role as a Middle Tennessee advanced-manufacturing hub.
MARQUEE PROJECT — SHOALS TECHNOLOGIES MEGA-CAMPUS: The single biggest project physically in Portland (Sumner County) is the new Shoals Technologies Group manufacturing campus. Shoals is headquartered in Portland and is the city's anchor public company (NASDAQ: SHLS), making this both an expansion and a consolidation of its hometown footprint.
SIZE & ADDRESS: A 638,000-square-foot, state-of-the-art manufacturing campus at 1500 Shoals Way, Portland, TN, on the Sumner County side of the city. It consolidates the company's three existing Tennessee facilities into one centralized location.
INVESTMENT: A $30 million initial investment, with a total commitment of up to $80 million over five years, per the company's announcement and the May 2026 opening release.
JOBS: The expansion is reported to add roughly 550 jobs over five years. The facility was reported as operational but still ramping toward full capacity in 2026.
TIMELINE & STATUS: A grand-opening ribbon-cutting was held May 18, 2026, with the public announcement May 19, 2026 (the event also marked the company's 30th anniversary). Status: OPEN and ramping to full capacity.
WHAT IT MAKES: Electrical 'balance of systems' (EBOS) and critical power infrastructure for utility-scale solar, battery energy storage systems (BESS), and data-center power — Shoals' core product lines.
A larger-sounding project — Create Energy's expansion announced in 2026 — is frequently associated with 'Portland,' but the bulk of that investment and jobs is actually at an Orlinda facility in ROBERTSON County, not Portland/Sumner. For Sumner-County Portland specifically, Shoals is the true marquee project.
RESIDENTIAL CONTEXT: Portland's new-construction growth continues alongside the job base, with the Planning Commission processing new single-family subdivisions, though no single residential project rivals Shoals in scale.
The $30M figure reflects the May 2026 opening release's 'initial investment'; the broader commitment is framed as up to $80M over five years. Job figures (~550) are drawn from coverage of the expansion and may be revised as the facility ramps.
