Solar distribution projects led warehouse commodity demand in Q2 2026, with utilization climbing from 60% to nearly 72% as the Midwest overtook the Southwest as the top region for space demand, driven by large solar distribution projects in St. Louis, Detroit, and Holland, Michigan.

Utilization surged from 60.4% in April to 71.8% in June across 1,456 facilities representing 315 million square feet.
Midwest captured 72.9% of Q2 space demand, overtaking the Southwest's dominance from Q1, driven by solar distribution projects.
Storage rates fell to $15.41 per pallet for Q2, down from $17.36 in Q1, creating a repricing lag despite tightening capacity.
Labor costs climbed to $44.91 per hour, up 6.8% from Q1, pressuring operator margins alongside softening rates.
Solar remained dominant for a second consecutive quarter, with the largest single project being a 487,000-square-foot solar panel distribution facility in St. Louis.

Utilization climbed from 60% to nearly 72% in three months, even as storage rates soften and labor costs push higher, according to the Q2 2026 PopPulse Data Index from PopCapacity.

"Utilization climbed every month through the quarter, ending Q2 at levels not seen since the peak inventory period of January 2026, while storage rates moved in the opposite direction, creating a repricing lag that Q3 will test," according to the report.

Key takeaways:

· Utilization surged all quarter — from 60.4% in April to 65.4% in May to 71.8% in June, across a tracked network of 1,456 facilities (~315 million square feet).

· The Midwest overtook the Southwest as the top region for space demand, capturing 72.9% of Q2 demand (vs. the Southwest's 73.3% in Q1), driven by large solar distribution projects in St. Louis, Detroit, and Holland, Mich.

· Storage rates fell to $15.41 per pallet (48x40) for the quarter, down from Q1's $17.36, even as capacity tightened.

· Labor costs climbed to $44.91 per hour, up $2.86 (+6.8%) from Q1, pressuring operator margins alongside softening rates.

· Solar remained the dominant commodity for a second straight quarter — this time centered in the Midwest rather than Texas — while toys and early GLP-1/pharma storage demand emerged as watch items for Q3.

· After the Southwest's dominance in Q1 (73.3% of space demand), the Midwest captured 72.9% of Q2 space demand, nearly the same magnitude of concentration, but on the opposite side of the country.

· The Southwest's share collapsed to just 2.2%, a direct reversal of its Q1 position.

· St. Louis anchored the Midwest quarter with a 487,000-square-foot solar panel distribution project, the largest single SOW of Q2 2026. Detroit and Holland, Mich., each registered near-identical 283,050-square-foot solar modules projects, echoing Q1's twin Dallas/Houston solar SOWs. Chicago and Indianapolis each added 150,000 square feet of food and consumer products SOWs, suggesting the Midwest consolidation shift extends beyond solar.

· Solar remained the leading large project commodity for a second consecutive quarter, now centered in the Midwest rather than Texas.

· Monthly utilization across the PopPulse network climbed from 60.4% in April to 71.8% in June, settling near ~66% for the quarter.

· Storage softened from $20.06 in April to $14.70 in June even as utilization climbed.

What to watch in Q3?

Whether June's ~72% utilization holds as a new floor rather than a one-month spike.
Whether storage rates begin repricing upward after two quarters of softening despite tightening capacity.
Whether a third geography emerges as the next solar distribution hotspot.
Whether labor costs above $44 per hour continue compressing operator margins.
