Experienced high-voltage specialists

Working with high-voltage power requires special expertise. Aggreko has more than 50 years of experience in power rental services and has provided high-voltage power services and solutions to major industries throughout the world.

Our operations have a global reach and combine high-quality equipment with extensive experience of developing and delivering high-voltage power solutions. We tailor our high-voltage equipment to match your requirements, whether you need temporary stand-alone site electrical power or base-load-scale multi-megawatt power for regional grids.

Aggreko’s high standards

At Aggreko, we set and achieve high standards across all our products and services. For example, all our rental equipment is purpose-built in our ISO-9001 accredited manufacturing facility in the UK.

Our project management service is also of the highest quality. Our team of skilled high-voltage technicians has received intensive Aggreko training specific to our equipment. This means that your electrical power project will be delivered by specialist project managers.

Safety is paramount in all Aggreko operations. We operate to the strictest health, safety and environmental policies and procedures to ensure a safe working environment.

Why choose us for your high-voltage power service?

In addition to our extensive experience in the rental power generation industry, there are several reasons to work with Aggreko. These include:

  • Turnkey service: We undertake a full range of project management activities, from engineering and design to commissioning and operation. This enables you to focus on your core business activities while we take care of the power system. 
  • Rapid deployment: With more than 190 service centres worldwide, Aggreko can provide electrical equipment and services rapidly, no matter where your project is located. This rapid response helps to minimise critical downtime on your projects.
  • Reduced capital expenditure: Renting equipment from Aggreko means that rather than investing large lump sums in expensive equipment with long delivery lead times, you can remunerate equipment costs over the life cycle of your project.
  • Additional services: Aggreko provides much more than high-voltage equipment; we also offer load testing of high-voltage installations to guarantee that equipment is operating at peak efficiency.
