Our highly reliable UPS systems ensure the continuous generation, transmission and distribution of electricity.


Our UPS systems are integrated in all kinds of power generation plants, including cogeneration, combined cycle, nuclear, hydro, thermal, wind and thermosolar. We also design and install UPS solutions to operate in transmission and distribution substations in order to protect switchgears, switch tripping systems, power transformers and T&D telecommunications.

Turbomachinery (Power Generation)

Installed as close to the turbine as possible, and possibly integrated into a shelter (especially for single shaft designs), the small footprint of the equipment is key, as well as its ability to operate in difficult environmental conditions (IP level, dustproof, vibration).

EBoP - Electrical Balance of Plant (Power Generation)

Depending on the critical level of the loads and on the type of utility, UPS will either have centralized or distributed back-up power systems. Battery selection and battery sizing is particularly essential for eBoP, because loss of power could result in complete power generation plant shutdown.

Substation (Power Generation)

At this stage, electricity leaves the power generation plant to the transmission and distribution network. DC UPS systems are necessary here to supply power to switchgear and telecommunication systems.

T&D Switchgear

Our DC UPS systems supply power to the coils or the motorized switchgears. Appropriate battery sizing and charger rating are selected to deliver 10-hour battery autonomy and a maximum of 8-12 hours recharge time.

T&D Telecommunication

The reliability of our DC UPS systems is key when supplying power to the telecommunication devices of remote substations, so that information is always available to the main control center.

T&D Control System (Transmission)

Our AC UPS systems supply power to the SCADA system of the substation to ensure permanent supervision and data acquisition (e.g. counting).

Expert ups solutions

We design UPS systems for the specific needs of Power and Utilities– delivering the quality, reliability and efficiency that this sector demands.


Choosing the right partner and the right product can make a big difference to power and utility operations, so we would like to highlight some of the main UPS considerations to help you make the right choice:

  • Isolating transformers must nearly always be considered
    In order to ensure galvanic isolation and to be able to perform earth fault monitoring.

  • Consider DC and AC UPS in 100% redundant and fully rated configuration
    This can ensure permanent power protection of all safety devices.

  • We advise using serial protocols or TCP/IP protocols in power plants, as well as auxiliary relays
    These enable a strong connection between the UPS and the control system.

  • We recommend DC systems in 48 Vdc for all specific utilities line telecommunication devices
    Battery must be selected according to environmental conditions and geographical location.

  • Consider 110 Vdc or 220 Vdc DC systems when powering coils of HV or MV switchgear systems
    These commonly offer battery autonomy of 10 hours.

  • It may be necessary to include a high rating battery charger in power plants
    This protects DC loads and also supplies several distributed inverters that protect AC loads too.

  • Care must be paid in the selection of the battery charger rating
    This device must be sufficiently rated to be able to recharge within 15 hours to restore availability.

  • DC UPS systems with highest MTBF are recommended
    This is often the best choice for substations placed in remote areas.
