The new HER1 digital hub bridges the connectivity and infrastructure gap in Southern Europe by interconnecting international, regional, and local subsea cables to better serve the EMEA region.
· Digital Realty’s new HER1 facility leverages Schneider Electric’s modular data center solutions to deliver the project in a remote location in 12 months, adhering to strict reliability and energy efficiency standards.
Schneider Electric, a leader in digital transformation in energy management and automation, has partnered with Digital Realty (NYSE: DLR), the world’s largest provider of cloud and neutral data center solutions, colocation and interconnection, to launch a new HER1 data center in Heraklion, Crete.
In early April 2025, HER1 became the first carrier-neutral facility on the island, playing an important role in bridging the digital divide in Southern Europe. It provides interconnection for international, regional, and local submarine cables, enabling cloud providers, telecom companies, and content delivery networks (CDNs) to serve the surrounding regions more efficiently.
HER1 works in tandem with rapidly growing markets, including Athens, Barcelona, Marseille, Rome, and Tel Aviv, and is a key part of Digital Realty’s Mediterranean data center platform. This is a significant step toward making Greece a strategic connectivity hub for Southern and Eastern Europe, North Africa, and the Middle East.
Following the successful implementation of a modular data center at its Marseille 2 (MRS2) facility, Digital Realty once again leveraged Schneider Electric’s EcoStruxure™ modular data center portfolio of Tier III-ready solutions. This enabled HER1 to overcome a number of challenges, including accelerated facility launch (less than 12 months), increased energy efficiency requirements, and the need to manufacture, test, and deliver equipment off-site due to its remote location in Crete.
To this end, Schneider Electric provided a specialized solution comprising two fully integrated, modular power units with medium-voltage (MV) equipment, transformers, low-voltage (LV) equipment, uninterruptible power supply (UPS) systems, and air cooling. Two large-scale all-in-one data halls with power, cooling, and IT were also installed, equipped with the EcoStruxure monitoring system for building and energy management (EPMS).
In addition, Schneider Electric provided a full range of design, construction, and consulting services for the data center, including all mechanical, electrical (M&E), and software equipment, manufacturing, assembly, commissioning, and security systems. This enabled Digital Realty’s HER1 facility to meet tight implementation deadlines while reducing the risk of on-site installation failures.
“Digital Realty’s significant investment in the new data center in Heraklion underscores our commitment to making the Mediterranean a global connectivity hub that connects continents and drives digital transformation,” said Fabrice Coccio, senior vice president of Digital Realty in France. “Through our strategic partnership with Schneider Electric, we are accelerating the launch of this important project to respond quickly to the growth of digital traffic in the region, while improving network reliability and diversity for businesses and communities.”
New gateway for Southern Europe
According to Telegeography, international capacity in Southern Europe has grown at a compound annual rate of over 30% since 2016, representing a sixfold increase in transmission capacity in the region.
Thanks to its geographical location and ongoing investments in submarine networks such as 2Africa, Andromeda, East to Med Corridor (EMC), Medusa, and Thetis, many organizations are choosing Crete as a strategic location for submarine cable termination and data center hosting. This transforms the region into a global interconnection hub connecting several continents.
HER1, Digital Realty’s first carrier-neutral data center in Crete, is located near the landing points of several of these submarine cable systems and will provide a highly reliable infrastructure for cloud services, submarine network operators, and communities requiring connectivity.
“Schneider Electric has been working with Digital Realty for many years to meet the highest standards of data center construction worldwide, and our joint HER1 project demonstrates the tremendous potential of modular solutions for delivering complex projects on a tight schedule with minimal risk,” said Pablo Ruiz Escribano, Senior Vice President, Secure Power and Data Center Business, Schneider Electric in Europe. “The successful implementation of HER1 is an important milestone in the development of data centers in Southern Europe. With the creation of this new global connectivity hub in Crete, Digital Realty will connect customers across continents for years to come.”
