Data center complexity goes beyond grid connectivity

Power is the pivotal factor for data center viability. AI and high-performance computing have pushed demand into the hundreds of megawatts, capacity is scarce, and grid connection dates are extending over several years. Diligence must test the connection date, reinforcement dependencies, security requirements, curtailment rights, expansion capacity and cost. An accepted offer is not the same as an energized connection.

Data center tenancy agreements - Routes to stabilization

The convergence of data sovereignty, security, power, cooling, connectivity, service agreements and AI-driven operational demands is transforming the traditional data center lease or co-location agreement into a hybrid instrument. Part real estate contract, part technology service agreement. This trend reflects the complexity of projects, number of stakeholders involved, and the pace of technological change.

Growing data center disputes risk

As builds become more complex, this risk escalates further.

The new dynamics of data center site selection

With greenfield land limited and grid connection timelines long, developers are widening their search for data center sites, crossing borders and acquiring land previously considered too compromised to be viable. Developers are buying infrastructure platforms rather than merely acquiring and remediating contaminated land.
