Internal and External Electrical Supply Design

Internal and external electrical supply design for buildings, solar power plants, networks up to 35 kV, substations, lighting, lightning protection and earthing systems.

Projects include technical documentation, required calculations, design solutions for approval by responsible institutions, and 3D system modelling in Autodesk Revit.

External Electrical Supply

Solar Power Plants and Solar Parks

Design for solar stations and solar parks of different capacities, including system configuration, equipment layout, grid connection and documentation for approval by AS “Sadales tīkls” and other institutions

BESS Systems

Battery Energy Storage System design, including energy storage solutions and their integration with solar energy systems and grid infrastructure

Overhead and Cable Lines up to 1 kV

Low-voltage overhead and cable lines, external electrical installations for buildings, lighting, connections to AS “Sadales tīkls” and low-voltage electrical supply networks

Overhead and Cable Lines up to 35 kV

Medium-voltage network design up to 35 kV, including internal networks for facilities and AS “Sadales tīkls” electrical supply network

Substations and Distribution Points

Transformer substations and distribution points up to 35 kV, including pole-mounted and container-type substations, distribution points and circuit breakers

Lightning Protection

Lightning protection design for buildings, including passive lightning protection for facilities and electrical infrastructure

Street Lighting

Street and outdoor lighting design for territories, access roads, parking areas, public spaces, technical zones and infrastructure facilities

Internal Electrical Supply

Building Electrical Systems

We design solar power plants and solar parks of different capacities, including system configuration, equipment layout, connection solutions and documentation for approval by AS “Sadales tīkls” and other institutions

Lighting

We carry out lighting calculations and design indoor lighting systems for rooms, work areas and technical spaces, taking into account functionality, visual comfort, energy efficiency and specific requirements of each facility

Earthing and Lightning Protection

We design earthing systems and lightning protection for buildings and their engineering systems, ensuring safe operation and reliable infrastructure protection

Calculations and Equipment Selection

We carry out electrical load calculations, voltage drop calculations, as well as cable selection and sizing based on technical requirements, system capacity and installation conditions

Audit, Documentation and Project Support

We audit and assess existing electrical installations, prepare technical documentation, provide designer’s supervision and coordinate documentation with relevant institutions

3D Modelling in Autodesk Revit

3D System Model

Electrical supply systems are represented in the digital model of the building or facility

Coordination With Other Project Sections

Design solutions can be coordinated more easily with architecture, structural design and other engineering systems

Fewer Errors During Implementation

A 3D model helps identify possible clashes, inaccuracies and technically complex areas at an early stage

Deliverables

What the Client Receives

The project is developed with consideration of technical requirements, coordination processes and practical implementation on site. Each solution is adapted to the specific facility, engineering conditions and project scale.
