Airports audited
48
ISO 50001 implemented
44 airports
Scope
National deployment
Large passenger jet parked at an airport gate at sunset, with a control tower on the right and another plane taking off in a blue-pink sky.
From compliance to measurable energy performance improvement 
As one of the world’s largest airport operators by passenger volume, the organization needed structured energy governance across its facilities.
Objectives
Detect inefficiencies and peak consumption. Implement ISO 50001 systems. Promote continuous energy improvement.
Opportunity
Energy regulations require large organizations to enhance efficiency and formalize energy management systems. 
Driving Complex Global Transformations

Proven delivery overcoming complex multi-country business challenges

Key Challenges
Worker in hard hat and high-vis vest uses a radio in a container yard as a forklift lifts a shipping container and a plane flies overhead in a bright blue sky
Complex infrastructure portfolio
Two business travelers in suits ride an escalator; a man reads a paper while a woman behind him holds a phone and pulls a cream suitcase.
Operational criticality of airport environments

Smart Grid for a More Efficient and Resilient Railway Network
A railway infrastructure operator implemented a smart-grid pilot on a major high-speed rail corridor to improve the monitoring and management of traction-power infrastructure, including electrical substations. The solution integrates telecontrol systems, energy meters, network analysers and an enterprise IoT platform, centralising consumption, power-quality and operational information in real time. This digital foundation supports a more proactive approach to energy management, asset maintenance and infrastructure reliability.

Cybersecurity Incident Response and Critical Infrastructure Recovery
Following a major cyberattack affecting a railway infrastructure manager, NTT DATA delivered incident-response and compromise-recovery services to assess the impact, contain the threat and restore control over critical technology infrastructure. The engagement included analysis of compromised accounts, access paths and persistence mechanisms, recovery of affected workstations and servers, and review of the security tools operating in the environment. The response combined crisis execution with a structured path towards stronger monitoring, resilience and preparedness
