Terawatt has carried out numerous electrical contracting projects for various production and industrial facilities. What typically characterises the electrification of production and factory premises is a higher-than-usual power requirement and longer power distribution distances. The required connection capacity often demands medium‑voltage expertise and experience with transformers and medium‑voltage switchgear. The electrical system for production operations should be designed as a flexible whole, tailored to the needs of the facility, and both outdoor and indoor lighting offer excellent opportunities for cost optimisation.
Electrical contracting for a production facility using the Design & Build model?
Electrical contracting for various types of production facilities using the Design & Build (KVR) model is our core expertise. Our customers trust our KVR capabilities — and for good reason.
Our main contractor clients receive a clear proposal that is easy to present to the developer and end user. Budgeting and coordinating different construction disciplines becomes easier when one building services entity is assigned to a skilled provider who also implements the plans on site.
At the beginning of the project, we focus especially on the needs of the end user: what activities take place in the facility? By thoroughly understanding customer requirements and the end user’s business, we can achieve the best possible outcome — one that benefits both the budget and the user.
Terawatt holds the S1 qualification, which means we can perform all electrical work required in the property, including transformer-related installations and other medium‑voltage tasks.
What I value most is Terawatt’s way of answering the call. They understand that once a project is accepted, it will be handled from start to finish. The people at Terawatt show responsibility and professional workmanship.
