Expanding electrical networks
Design review avoided potential cost and disruption
Challenging issues arose during the design and construction phase of our client’s onshore substation.
Developing substation and transformer installations
World’s largest railroad converter
A 400kV substation, incorporating the world’s most powerful railroad converter, and a 100kV auxiliary connection were planned for our client’s new 1,100 MW coal-fired plant in Germany. We delivered project management, engineering, commissioning, quality assurance and quality control and temporary operation of the switchyard. The project was executed on time and in budget so that our client was able to successfully commission the 413 MW railroad converter, which is capable of supplying 25 percent of the power required by Germany’s rail network.
Providing access to the grid
Repowering a wind farm
Our German wind farm client planned to repower from 100 to 125MVA and their existing infrastructure needed analysis regarding capacity reserves and upgrade measures. We provided an OEM-independent study of spare capacities of transformers, switchgears and cables to minimize CAPEX and to extend lifetime of existing assets. We advised that only minor investments would be necessary to keep the electrical assets of the grid connection fit for future purpose. Our client avoided outages during the rebuild and benefited from a significant reduction in CAPEX for electrical infrastructure.
Delivering the benefits of local energy grids
Innovative community energy system
Our design provides a sustainable and scalable model for rural communities and businesses to tackle fuel poverty.
Optimizing networks and operational efficiency
Asset management and maintenance improved
Our UK client engaged us to create an engineering governance framework and optimized maintenance strategy for their 110kV private network overhead line and substations connecting two manufacturing sites, 7km apart across a densely populated area. We redefined their asset management strategy and tendering for maintenance services. Our client benefited from reduced OPEX and also achieved both health and safety and environmental compliance.
