Together with our network of experienced experts, we provide the work specifications, management, and evaluations that enable the start of the design engineering process:

  • Topographic and land owner survey
  • Soil investigation
  • Grid assessment / Power quality measurement

Electrical studies are typically the first step when applying for a grid connection, ensuring that products and infrastructure comply with grid code requirements and allow evaluation of connection possibilities.

The scope of the studies strongly depends on the characteristics of the given Point of Common Coupling and the desired application. From steady-state to transient regimes, it is important to use the right tools and accurate models. These studies are often conducted by highly specialized engineers with strong software skills but limited overall understanding and construction experience. Given the wide range of possibilities, it is not uncommon to lose focus on the main objective.

We offer the necessary support, interpretation, and decision-making for all electrical studies. Together with our partners, we provide the following studies:

  • Power Flow
  • Short Circuit Study
  • Insulation Study
  • Selectivity Analysis
  • Potential and earthing system calculation
  • Static and dynamic capabilities
  • EMTP transient studies
  • Harmonic Analysis

All the basic studies required to support a Basic Engineering Design Package, containing all technical data needed by a competent contractor to perform detailed execution engineering and prepare an offer. It includes:

  • Location of grid connection point
  • Grid code analysis / Grid compliance solution
  • Power system studies
  • SLD
  • Layout
  • Communication layout
  • Definition and rating/sizing of main equipment specifications
  • Preliminary single-line diagram
  • Preliminary works layout
  • Definition of protection and control devices
  • Definition of metering device locations
  • Equipment specification / Works specification (descriptive memory)
  • Quality plan (minimum requirements)

The required input for basic engineering is typically a feasibility study or conceptual design of the grid connection.

The required input for the basic engineering is normally a feasibility study or conceptual design.

The substation is a fundamental component in connecting the asset to the grid. IIt is a complex system that has a major influence on compliance with the grid code. It often constitutes a separate scope with its own construction contract.

This service package includes:

  • Layout of the switching yard, building plan, and room plan
  • Single-line diagram
  • Dimensioning of the primary equipment (transformers, switchgears, power cables, neutral impedances)
  • Dimensioning of the secondary equipment (current and voltage transformers, protection, metering, control devices)
  • Auxiliary services, lighting, earthing, climate control, communication systems
  • Trenches and foundation plans
  • Works schedule
  • Responsibility interface
  • Equipment specification
  • Tender and contracting support
  • Equipment FAT and quality assessment
  • Site supervision and quality control
  • SAT and final acceptance

For connecting the wind or solar asset to the grid, medium-voltage, communication, and earthing grids must be created. The layout and dimensioning of these grids have a strong influence on the project’s investment and operating costs. Experience and expertise are essential at all stages of the project, from engineering to tendering and project execution.

This service includes:

  • Layout of the power, communication and earthing cables
  • Dimensioning of the power cables (short-circuit study, power flow)
  • Single-line diagram
  • Connection scheme of communication
  • Cable trench and foundation cable-laying schemes

The design of civil works and related infrastructure has a strong influence on the project’s investment cost. Experience and expertise are essential at all stages of design, which should be performed in accordance with international regulations.

This service includes:

  • Evaluations of design types
    • elaboration of concept, preliminary, and detailed designs, and their Bill of Quantities
  • Structural design
    • generic concrete and steel structures for towers and foundations
  • Geotechnical design
    • design of geotechnical campaigns, geotechnical studies and specifications, foundation analysis, and soil–structure interaction

Design of civil works infrastructure according to international regulations and OEM specifications:

  • Road design
    • design of wind or solar farm road layouts, design of wind farm hardstands and site compounds, and optimization of wind farm layouts
  • Design assessment
    • Structural design verification and structural design improvement/optimization
