Power systems
Electrification and changing consumption behaviours strain our current power systems. An optimised electricity grid with reliable connections is vital to meet growing consumer needs efficiently.
The energy grid sets the pace of the green transition
In today's evolving landscape power systems technologies face significant challenges, such as integrating renewable energy sources, managing grid constraints, and ensuring cost-effective and timely connections. At Ramboll, we see these challenges as opportunities to innovate and implement adaptive power systems solutions.
Ramboll has 300+ power systems consultants and engineers who provide expert services independent of suppliers. In August 2025, TransGrid Solutions joined Ramboll. The company is recognised as one of the top consulting firms in HVDC systems, with extensive expertise in advanced grid modelling.
“The acceleration of global electricity demand highlights the significant changes taking place in energy systems around the world and the approach of a new Age of Electricity. But it also presents evolving challenges for governments in ensuring secure, affordable and sustainable electricity supply.”

FEATURED PROJECTS
Ramboll is helping Energinet and Nexel enable the Danish grid to support greater amounts of renewable energy as overall energy demand rises.
Ambitious work is underway on the world’s first energy islands – marking the next phase in the green energy transition.
The PTES project and a modern district heating network are the cornerstones of Meldorf’s new smart energy system. The new setup not only reduces carbon emissions, but also provides flexibility and security of supply to the residents of the small town in North-Western Germany. It's also the country's first and largest such project.
iM3NY is a new lithium-ion battery gigafactory, and a critical link in driving the energy transition. It is North America's first lithium-ion battery factory that features innovative technology for producing sustainable, high-performance batteries.
