Applus+ provides technical inspection and digital environmental management services for Chile’s first HVDC transmission line

Technical inspection and digital environmental management for over 600 km of HVDC line

Applus+ will conduct technical inspections across three strategic segments of the project, totalling 637 km of HVDC line—equivalent to 48% of the total route.

The segments include:

• The expansion of the Kimal substation and installation of the converter station.
• The line section from Kimal to tower T-875V2 (approximately 444 km).
• The line section between tower T-875V2 and tower T-1283 (an additional 193 km).

One of the key differentiators in Applus+ offer was the inclusion of the Ambiens Q platform—a digital solution for environmental information control and traceability. This tool is especially valuable for large-scale projects with multiple regulatory commitments. It strengthens regulatory compliance and facilitates sustainable project management.

This HVDC project addresses an urgent need: the current transmission lines lack the capacity to evacuate renewable energy from northern Chile—a region with high solar and wind potential. Building this new line will enable more efficient energy distribution and help decarbonise the country’s energy matrix.

Applus+ will contribute its expertise in technical inspection, QA/QC management, operational health and safety, and environmental sustainability, ensuring that construction is carried out in line with technical standards, within defined deadlines, and with a zero-accident focus.

Technological deployment in Chile’s most important HVDC transmission project

Key highlights for Applus+ in this project include:

• Participation in the country’s most important electrical transmission project, with high strategic and institutional value.
• Strengthening Applus+ positioning in Chile’s energy industry, particularly in HVDC and large-scale projects.
• Use of advanced technologies, including drones and digital platforms for monitoring, quality control, and real-time reporting.
• Greater corporate visibility by being involved in a nationally recognized project supporting Chile’s energy transition.

Since 2023, Applus+ has maintained a consultative relationship with the client—understanding their needs, aligning its value proposition, and showcasing experience in complex energy and infrastructure projects. This close relationship enabled the presentation of a strong technical proposal tailored to the context and challenges of the project.

During implementation, Applus+ will employ technological platforms, including drones, to generate audiovisual records, track progress, and provide periodic reports to the client. These materials will also be used for public updates on progress and results, reinforcing transparency and a commitment to innovation.
