Digital Realty has begun construction of FRA20, a major new data centre within its Digital Park Fechenheim campus in Frankfurt. The project signals the company’s next phase of investment in digital infrastructure that supports rapidly rising AI workloads while aligning with sustainability expectations across Europe. With 16 megawatts of planned IT capacity and a design tailored for high-density computing, FRA20 illustrates how operators are adapting to both technological and environmental demands.

A New Build Designed for AI’s Growing Infrastructure Needs

FRA20 is being developed in two stages and will provide more than 8,100 square metres of usable white space once fully completed. The facility is engineered to support large-scale AI and machine learning applications, which require far greater power and cooling capabilities than traditional enterprise workloads. Digital Realty has positioned the site as part of a wider effort to anticipate the next wave of digital transformation. European organisations, particularly those scaling generative AI or real-time analytics, increasingly require facilities that can sustain dense compute clusters. FRA20 is expected to help bridge this capacity gap by offering infrastructure aligned with both performance and regulatory expectations in Germany’s technology landscape. Senior Vice President Volker Ludwig said the investment reflects Frankfurt’s strategic importance as a data centre market and the continued momentum behind AI-ready environments. He highlighted that Digital Realty is expanding not just capacity, but an ecosystem designed to host the most demanding workloads with long-term operational stability.

Building Out a Multi-Facility Sustainable Technology Campus

FRA20 forms part of the broader Digital Park Fechenheim development, a large-scale campus that could ultimately include eleven interconnected facilities. At full buildout, the site is expected to deliver around 200 megawatts of IT capacity spread across approximately 90,000 square metres. Five of these centres, including FRA18 which opened earlier in the year, will occupy the Eiermann Building, a historically listed structure undergoing redevelopment for data centre use. The adaptive reuse of this iconic building demonstrates how operators can expand digital capacity without relying solely on greenfield construction. FRA20 is scheduled to begin initial operations in the spring of 2027, contributing an additional tranche of scalable capacity as customer needs evolve.

Engineering for Heat-Intensive AI Workloads

The technical design of FRA20 reflects the realities of modern compute environments. AI engines generate large volumes of heat, and traditional cooling systems often struggle when densities climb. To address this, FRA20 incorporates advanced thermal management systems and equipment layouts that can accommodate the next generation of AI chips. Digital Realty’s planning process anticipates future shifts in hardware requirements, ensuring the facility can adapt rather than undergo repeated retrofitting. The expansion of such AI-capable infrastructure is becoming a defining feature of data centre investment across Europe, where organisations seek partners capable of providing reliable power, cooling efficiency and operational resilience.

A 100 Percent Renewables Commitment as Environmental Pressures Rise

A core element of the FRA20 project is its reliance on renewable energy. Digital Realty confirmed that the site will operate using electricity sourced entirely from renewables, continuing the company’s broader commitment to energy transparency and climate-aligned development. The renewable supply arrangement is an important differentiator in a sector where rising power consumption has intensified scrutiny. With AI models driving exponential growth in energy demand, companies are under pressure to ensure that their digital infrastructure does not conflict with climate commitments. FRA20 therefore offers customers a pathway to expand computing capacity without increasing their reliance on fossil-based grids. This approach aligns with Germany’s climate policies as well as the expectations of corporate clients who now factor energy sourcing and sustainability credentials into procurement decisions.

Frankfurt’s Strengthening Position in Europe’s Digital Economy

Frankfurt continues to serve as one of Europe’s most important data centre markets, supported by strong connectivity, a concentration of cloud providers and a robust enterprise ecosystem. Digital Realty’s latest investment reinforces the city’s status as a hub for next-generation computing infrastructure. The vision for Digital Park Fechenheim extends beyond delivering capacity. The company aims to create a campus that allows customers to scale workloads across multiple facilities with consistent performance, proximity and interconnection. FRA20 will expand the city’s ability to host cloud, enterprise IT and AI development workloads, complementing FRA18’s recent focus on AI-optimised operations.

A Step Forward in Sustainable, High-Performance Digital Infrastructure

The development of FRA20 highlights Digital Realty’s strategy of marrying sustainability principles with the technical requirements of modern computing. As organisations increasingly seek infrastructure that can support AI while advancing their climate goals, the facility represents a model for how large-scale data centres can evolve. With construction now underway, FRA20 marks a meaningful addition to Europe’s digital landscape and underscores how the sector can expand capacity in line with renewable energy commitments, efficient design and future-ready engineering.
