Regional guides

The same machine, six different design bases. The matrix is the durable shape of each market — every volatile figure behind it is date-stamped on the region pages, pulled live from the numbers register.

Banded characterizations — the dated, sourced figures (queue years, deposits, tariffs) live on each region page.

Northern Virginia & PJM

The densest data-center market on earth sits inside PJM, where interconnection queues, transmission buildout, and county-level land-use politics now set the pace — not capital. Data-center alley's grid position makes speed-to-power the defining regional constraint.

Verdict: Deepest ecosystem, longest queue — buy speed with an existing position, or don't play.

Texas & ERCOT

ERCOT's energy-only market, fast interconnection paths, and co-location with West Texas wind, solar, and gas make it the speed play — priced in exposure to scarcity pricing, curtailment economics, and grid-islanding risk that the design basis must own.

Verdict: Fastest to energize — priced in scarcity, curtailment, and islanding risk you must design for.

Ireland & Dublin

Dublin was the canonical moratorium market; since December 2025 it is the canonical conditional market. CRU's connection policy reopened applications — priced in matched dispatchable generation and an 80%-additional-renewables obligation — while EirGrid still classifies Greater Dublin itself as fully constrained. It remains the leading indicator for how European grid operators gate data-center load.

Verdict: Bring your own generation and renewables — Dublin itself is still a 2030s conversation.

The Nordics

Cheap northern hydro and cool climates made the Nordics the efficiency play — 2025 day-ahead averages ran ~€9–17/MWh in the far-northern zones. But the tax honeymoon is over (Sweden 2023, Finland July 2026), waste-heat mandates are hardening into statute, and the grid queues are now real: 7 GW of data-center requests pending at Svenska kraftnät and >100 GW of inquiries at Fingrid shape what actually gets built.

Verdict: Cheap hydro and free cooling, priced in mandates, ended tax breaks, and distance — built for training, not latency.

The Middle East

Sovereign-backed gigawatt campuses in the UAE and Saudi Arabia trade the West's interconnection-queue problem for a different design basis: hot-arid climate hardening, water-scarce cooling, imported supply chains, and export-control geometry on the silicon itself.

Verdict: Power is the easy part — silicon allocation and climate hardening set the real schedule.

Asia-Pacific

APAC splits into land-and-power-scarce hubs (Singapore's capacity-gated allocations, Japan's grid-frequency split) and scale markets (India, Malaysia, Indonesia) where subsea-cable geography and 50 Hz grids drive different electrical and network design bases than the US default.

Verdict: Two different games: win allocations in the hubs, win execution in the scale markets.
