Sirti Energia specializes in the design, building and maintenance of underground and aerial networks, energy transportation and distribution. We build power lines, providing the entire supply chain, from permit applications to the construction of pylons, pipe excavations, testing and maintenance. Specifically, Sirti carries out assembly, maintenance and repair work on AT-MT-BT power lines, earthmoving works, ropeways, works in mountain environments, aqueducts and gas pipelines, public lighting, transformer rooms, wind and photovoltaic installations. To consolidate our expertise, presence and operating capacity in the energy sector, Sirti has acquired the entire share capital of Foi & Vitali power lines S.p.A., a company already engaged in the construction and maintenance of high and low-voltage power lines for large clients.

The ability to integrate different technologies and the use of innovative ICT services make intelligent management of utilities possible. Intelligent monitoring of consumption data for any system, and the use of technologies with a low environmental impact allow energy savings. Sirti can manage all phases of the operating process, creating remote control and automation systems, implementing interventions for network rationalization, analysing and evaluating electromagnetic fields for high, medium and low voltage power lines.

In addition to building installations and systems, Sirti provides preventive maintenance and offers assistance in the project’s financing aspects.
Photovoltaic
Turnkey solar energy systems
Photovoltaic
For the realization of medium and large sized photovoltaic installations, we don't just limit ourselves to the design and building phases, but extend our services to the system's management and maintenance, providing control systems (Remote Control and Security) and developing installations.
Wind
Turnkey wind power plants
Wind
In the wind energy sector, we support our customers in the design, construction and management of different types of installations (maintenance, remote control and physical security from theft or vandalism).
Cogeneration
Turnkey cogeneration and trigeneration plants
Cogeneration
Systems for the joint and simultaneous production of electricity and heat, using the same fuel source in a single integrated system. In this area, we provide assistance for the installation's entire life cycle: from feasibility studies to system implementation and after-sales service.
Sirti has always considered energy efficiency and sustainability as essential guidelines in its operating and business models. This is why it was natural for us, over the years, to develop a range of solutions aimed at ensuring less waste, consumption, costs and emissions. These solutions are aimed at creating efficiency in large buildings, industrial sites, railway stations and generally in contexts characterized by high energy and heat consumption.
Power & HVAC (Heating, Ventilating and Air Conditioning)
As a general principle, in order to make the elements that deal with the power supply function more efficient, the efficiency of each individual element (rectifier, UPS, inverter, etc.) is determined by using high-performance machines (in relation to the state-of-the-art) and making them work within the best performance curve.
As far as the air conditioning function is concerned, in addition to the use of more efficient machinery, favourable climatic conditions (free-cooling) can be exploited by applying heating/cooling recovery techniques and dynamically adjusting the regulation and efficiency of aeraulic flows.
Any intervention begins with an on-site preliminary study of the situation, proceeding on to determine the most feasible system consistency, operating methods, identifying abnormal situations, etc. We then come up with potential systems efficiency proposals, defining them in terms of technical and economic implementation, achievable energy savings and return on investment.
Energy Solutions for Datacenter Solutions
Energy Solutions for Datacenter
Data Centers are characterized by installations with high electrical power ratings (in the order of 3-5 kW/m2). The heat produced by the equipment installed requires additional power for its proper dissipation.
The site's reliability is the fundamental driver in making design choices. Within the context of an energy efficiency project, it is therefore essential to take such reliability requirements into account, prior to any intervention.
Energy Solutions for POPs and Power Plants
Energy Solutions for POPs and Power Plants
POPs and TLC power plants have similar energy consumption specifications to those of Data Centers: type of generators and absorbers, cyclical consumption, etc. The type of service intervention is very similar and the areas of intervention are effectively the same: air conditioning, lighting and energy production.
In terms of energy production, wherever possible, we make use of equipment providing a higher performance rating.
Regarding air conditioning, in addition to the obvious use of better performing machinery, we provide a design that takes advantage of favourable climatic conditions, improving the efficiency of aeraulic flows and recovering heat/cold discharges.

Energy Solutions for Mobile Radios
The energy consumption characteristics of mobile radio sites are constant for the equipment's power supply function (24/7 year round), while the air conditioning function is variable and depends on the outside temperature.
