MERLIN Edged Bilbao-Arasur Campus
- Planned critical IT
- 280 MW
- Updated
- Oct 29, 2026
MERLIN’s Bilbao-Arasur campus in Ribera Baja, Álava combines initial operations with later development phases. Its published phase table totals 280 MW of planned IT capacity across 22 MW, 96 MW and 162 MW phases, not current operating load. In July 2026, MERLIN reported initial operating revenue, two future 48 MW buildings pre-let and requests for further building licences. Adjacent solar generation is separate. Waterless cooling and WUE 0.00 are operator claims, not independently measured total-site water use. Parcel title and separate project financing remain unverified.
Capacity
Operating IT capacity: Not established in published records
A missing figure does not mean zero. Planned, utility and generation figures are not operating IT capacity.
Development
22 MW IT initial phase, within derived 280 MW masterplan. Evidence: SRC-N215-MERLIN-NAVALMORAL-M1
2 buildings
96 MW IT across two 48 MW pre-let buildings, with future delivery rather than operating load. The campus update reports construction of the second building progressing and the third beginning in early 2026. Evidence: SRC-N215-MERLIN-NAVALMORAL-M1; SRC-N215-MERLIN-BILBAO-M2; SRC-N215-MERLIN-BILBAO-M4
162 MW IT further masterplan phase; not current operating capacity. Evidence: SRC-N215-MERLIN-NAVALMORAL-M1

Reviewed bio water context
Source reportFor the three building scope, the decision estimates 1,150 m³ per year of municipal water for sanitary and fire system uses once all three operate, and describes dry cooling. This is authorization scope design consumption, not measured use, zero total water use or a full masterplan forecast.

Reviewed bio aai context
Source reportThe environmental decision signed October 16, 2025 formulates the environmental impact declaration for regulatory Building 1 and modifies the integrated environmental authorization held by Merlín Logística, S.L.U. for Arasur. The three building design totals about 190 MW electrical power: Building 3 has 22 MW critical plus 8 MW general services, Building 2 has 48 MW critical plus 22 MW non critical, and Building 1 has 60 MW critical plus 30 MW non critical. These are regulatory design quantities, not operating load or the later 280 MW IT masterplan; regulatory labels are not verified commercial building identifiers.

Source reportRibera Baja council approved the second amendment to the supermanzana 6 first phase detail plan on January 26, 2026, published February 4. The notice names Merlín Properties SA as promoter and Lks Krean as author. Detail plan approval does not establish land title, building completion or commissioning.
SourceReviewed bio dec2025 context
Source reportIn its February 26, 2026 results announcement, MERLIN reported that the third Basque 48 MW building had obtained its construction licence and begun works in December 2025. That dated operator account remains unreconciled with the later description of an early-2026 start, and its regulatory building number has not been established.

Reported context
Adjacent solar installation is generation, not IT capacity; do not add it to campus load.
Reported context
Operator campus update advertises waterless cooling and WUE 0.00. This is a campus cooling design/performance claim, not independently measured annual total-site water withdrawals. It does not establish water supply allocation or discharge.
Reported context
Operator advertises transatlantic/northern-Europe connectivity and links to its Iberian sites.
