Engineering Services

Experienced. Flexible. Objective.


Utilities should be able to implement technical advances economically, with maximum supply security.

Converting and expanding network assets, integrating renewable energy, and adopting new communication standards all require adaptations to protection and measuring technology.  You need an experienced partner who can provide competent, independent guidance to achieve this objective.  Our services are designed to help you continue to operate your network economically and ensure supply security in the future.  

You can also enjoy the benefits of our manufacturer-neutral advice and experience gained from over 20 years as a successful partner to network operators of all sizes.
