Construction, design, and supervision services for high voltage power lines and substations.

Company background

OHLAS started its operations in 2011.

With the expansion of the business, a new limited company, OHLAS Consulting Oy, was established in 2021.

All work related to consulting, training, site management, and supervision was transferred to the new company.

The company’s operations are entirely focused on power line and substation projects. The clientele mainly consists of contractors and local network companies.

In 2023, OHLAS Construction Oy was established, offering high voltage power line installation services.

We offer installation services ranging from individual towers to larger projects.

Installation services include foundation work, tower assembly and erection, and conductor installations.

We have worked on many international projects and can offer our services in several different languages.
