First Block EST-1 is a large-scale heat-reuse data center designed as a new-build facility, colocated with three operating industrial factories requiring continuous thermal loads. The project includes 40 MW of power capacity and 100,000 ft² of developable IT space, with recovered heat feeding a mechanical vapor recompression (MVR) system that generates 40 MW of low-carbon process steam. This advanced thermal integration supports regional decarbonization while enabling stable industrial operations. With multiple carriers and an 18-month lead time, EST-1 is tailored for hyperscale AI deployments requiring deep heat-reuse integration.
FirstBlock builds data center campuses around a simple idea: the best digital infrastructure begins with the best energy. Originating in Québec, we developed deep expertise in identifying clean, low-cost power markets and transforming them into high-performance environments for cloud, AI, and HPC operators. Today, we apply that expertise across Canada, selecting regions with stable, low-carbon power and shaping them into liquid-ready, high-density sites optimized for next-generation workloads.
Our campuses turn energy advantages into operational benefits. Advanced hydrocooling and large-scale heat-reuse systems drive consistently low PUE, improving efficiency while reducing environmental impact. Each location is prepared for rapid deployment with permitting, utility alignment, and engineering groundwork already completed, giving tenants a predictable and accelerated path to scale.
By combining energy intelligence, sustainable engineering, and a commitment to long-term cost competitiveness, FirstBlock offers operators a reliable, efficient infrastructure platform built for growth.
