Project Design & Execution
Enersynt provides specialist power system engineering knowledge throughout all stages of high voltage projects. As an owner's engineer, providing independent electrical engineering advice and expertise, or as an integral member of your project team, we go the extra mile to ensure project success.
Concept design & techno-economical optimisation
The optimal planning of grid connections has always been a considerable task. The size of renewable energy projects and the share of intermittent and non-storable sources of energy in the grid are increasing.
This makes grid connection design and operation of large scale renewable power plants more and more complex. The addition of interconnectors, storage systems and the constant pressure to drive down the costs further adds to the engineering challenges of these grid connection systems.

Techno-economic optimizations
Reducing the lifetime cost of energy
Our high voltage design engineers have developed an efficient mathematical optimization toolset to drive down LCoE by determining the most suitable solution for your project while accounting for the full lifetime costs.
Capital expenditures
Make informed decisions on your CAPEX due to the material and labor costs during the design, construction and commissioning phase.
Operating expenditures
Get a grip on the OPEX costs resulting from active power losses and the operations and maintenance requirements for each solution.
Expected energy not served
Find the right balance between a reliable design with high availability and its impact on the CAPEX, OPEX and insurance fees.
Site & technology specific
Consider site specific production profiles, cable corridors, exclusion zones, existing infrastructure, and calculate accurate 3D cable routes based on the bathymetry and soil conditions.
Cutting-edge grid connection optimization algorithms
Our tailer-made offshore wind farm inter array and export system optimization algorithms are the result of a multi-year collaboration between academia and our high voltage experts and are based on a mathematical structure with proven optimal results.
Substation location
Find the most suitable location with heatmaps showing the cost impact compared to alternative substation locations.
Cable design
Determine the optimal number of inter array strings, voltage level and cross section of all wind farm cables.
Branching of strings
Unlock further savings potential with reduced cable lengths, losses and increases in system reliability by branching strings in strategic locations.
Existing infrastructure
Navigate existing infrastructure and determine the most suitable crossing strategy based on your project specific needs.
Exclusion zones
Avoid shipwrecks and other no-go zones and intelligently decide if areas resulting in increased costs are worth avoiding.
3D cable route finding
Gone are the days of rough point-to-point estimates, get accurate cable lengths based on flexible 3D route finding.
Proven results through innovation
Multi-million project savings
Using advanced optimization algorithms can accelerate project engineering and offer many opportunities for improvement and cost reduction in the inter array and transmission system of a project. For this 1.5 GW offshore wind farm, the optimization result was benchmarked against the manual design prepared for a competitive auction.
The cost savings are made through multi-objective optimization, optimal substation positioning and simultaneously considering the export cable and collection circuit costs.

Detailed grid connection design
Our high voltage engineers take your initial grid connection concept to a full-fledged design. With due consideration for lessons learned from our past projects, the right design decisions are taken at all stages of the project.
By starting with grid studies, the most suitable equipment and cable ratings can be selected. These results form the basis of the technical specifications and substation design. Depending on the needs of the project, this can be further developed into a detailed layout and electrical design, including the engineering of the control & protection system.

Site experience
Construction & commissioning supervision
Our electrical engineers are no desk jockeys. We are fully certified for both onshore and offshore works to actively ensure contractor performance. Through our presence on site, we can monitor progress and ensure equipment is to specification and functioning correctly.
Technical supervision and management of the entire electrical package
Deep technical design knowledge and hands-on commissioning experience
No signal or operational state remains untested
Tender support & evaluation
Enersynt can help you to identify the most suitable contracting strategy for your project. Our grid connection consultants write clear and concise tender packages, fit for purpose and without being overly prescriptive.
We support you through all stages of the supply chain engagement by determining the evaluation criteria, engaging with tenderers on clarifications, performing independent reviews of the tender proposals, and by preparing recommendations for the tender award.

Luxembourg PV
Situated in the Luxembourg province, Wallonia, Belgium, the Diodi solar farm is a planned 40MW PV installation set to be connected to the Elia grid. Initially designed for 70kV operation, the connection will be upgraded to 110kV post-2030.
Efficiency assessment transmission projects
Together with AFRY, Enersynt has been entrusted by the ACM with assessing TenneT's high voltage transmission projects to ascertain their adherence to various objectives and efficiency standards.
Deux-Acren
Corsica Sole has developed a 50MW/100MWh battery energy storage system (BESS) in Belgium. Enersynt was entrusted with ensuring compliance with the Elia Type C grid code requirements for Storage Park Modules (SPMs).
Northwester 2
The Northwester 2 offshore wind farm is located in the North Sea, off the Belgian coast. The grid connection of the wind farm is realized through an offshore high voltage substation which is connected to Elia’s Offshore Switch Yard (OSY) to export the energy to shore.
Neptune H2opZee
The H2OpZee project represents a pioneering effort in offshore hydrogen technology, developed jointly by Neptune and RWE. The project envisages the offshore production of hydrogen fed by an offshore wind farm with a nominal capacity of 525 MW.
