High-voltage electrical engineering

At Head Energy NorGrid, we have extensive experience in connecting wind farms, power generation facilities, industrial sites, and electrification projects to the grid. We assist clients in designing the optimal connection to the transmission/distribution network and are fully equipped to handle everything from permit applications and negotiations with grid operators to analyses and studies required to realize projects in compliance with grid connection regulations.

Our broad expertise, down to the component level, enables us to evaluate and design robust grid connections that are cost-optimized for power losses, operational reliability (redundancy), and maintenance throughout the facility's lifecycle.

At Head Energy NorGrid, we have extensive experience in executing projects. Our skilled technical project managers have successfully delivered numerous projects, ranging from large-scale construction projects such as power plants and wind farms to development initiatives and smaller maintenance tasks.

We are involved throughout the entire project lifecycle—from the concept and development phase, through analyses and studies, preparation of tender documents, design, commissioning, and all the way to the final implementation and handover to the end client/operations.

We ensure high-quality execution of your project, delivering on time and within the agreed budget.

Head Energy NorGrid offers a wide range of expertise and experience in the design and engineering of high-voltage electrical installations, covering voltage levels from 1 to 420 kV.

Our engineers specialize in electrical installations, including high-voltage supply systems, transformer stations, power generation facilities, and industrial applications. We also have extensive knowledge across various disciplines related to electrical supply systems.

At Head Energy NorGrid, we have extensive experience in conducting site inspections and commissioning. Our team has successfully completed numerous projects, ranging from large-scale construction projects such as power plants and wind farms to smaller development and maintenance tasks.

Our specialists frequently participate in site inspections and commissioning of all types of electrical systems, including low-voltage and high-voltage installations, rotating machinery, transformers, switchgear, control panels, protection relay panels, and more. This ensures critical evaluation and testing of procured equipment to guarantee both functionality and quality.

We also assist with routine testing and troubleshooting of systems in the event of failures or incidents, ensuring that appropriate replacements or adjustments are correctly implemented to restore system operation.

Head Energy NorGrid possesses expertise in performing various technical analyses and calculations, including:
