QTS South Dallas DC3 — 303 Mason Road
Overview
TYPE3’s map data lists QTS South Dallas DC3 in Lancaster with QTS Data Centers as operator, Announced status, and 0 MW. The note matches the 560,000-square-foot, two-story building and November 2025–January 2027 window. Coordinates match DC2 at 32.58725, -96.69647. That shared pin is campus-level, not proof DC3 is the same hall as DC2.
Dallas Morning News treats DC2 and DC3 as the two April 2025 TDLR additions on Mason Road, together about $650 million, and explicitly notes no disclosed wattage. Checkmark’s case study calls DFW2-DC3 a 560,000-square-foot two-story hall with 43 MW projected critical power, $350 million, Highland Associates, Rogers-O’Brien as general contractor, and substantial completion by January 2027. It also says TDLR announcement language from April 2025. Treat 43 MW as contractor/projected critical power, not measured load and not a state wattage disclosure. TYPE3’s map data remains Announced with 0 MW.
Do not add 43 MW to DC1 or DC2. Do not confuse this row with DC7 at 1341 Sunrise Road (TABS2026016944, SEO-034). QTS has not published a TDLR project number, critical-IT design, construction state, or currently quoteable block for this record. Preserve Announced / 0 MW. Floor area and dollars remain filing layers, not campus IT capacity figures.
Questions
Is DC3’s 43 MW official TDLR wattage?
No. Dallas Morning News says the April 2025 filings did not disclose wattage. 43 MW appears in a contractor case study as projected critical power.
Does DC3 include DC7?
No. DC7 is a later child at 1341 Sunrise Road, not 303 Mason Road.
Can 43 MW be added to DC1 and DC2?
No. Child projected-power layers stay unmerged and are not saleable IT.
