Ing. Guglielmo Speciale- Proprietario ed Amministratore Unico Italtekno s.r.l.

Eng. Guglielmo Speciale – Owner ed Chief Executive Officer of Italtekno s.r.l.

Esco.One is a trademark owned by Italtekno s.r.l. a company acquired in 2017 by the majority shareholder and managing director of 2G Consulting s.r.l.; The latter since 2010 is set to become one of the most solid and important realities in the renewable energy sector.

In recent years, the ownership of Italtekno s.r.l. has been at the heart of the development of renewable energy activities in Sicily; it have been made:

  • hundreds of photovoltaic plants both industrial and civil (including the largest industrial plant in the province of Palermo) as well as other industrial photovoltaic plants in Palermo, Carini, Marsala, Gela, Acireale, Scicli, Syracuse, plants serving Public Administrations , etc. etc,
  • plants for the production of sanitary hot water from a predominantly industrial thermal spring (swimming pools, hotel structures, sports fields);
  • reduction of consumption with LED efficiency systems (Falcone Borsellino, GDO, etc etc);
  • design activities of mini wind parks, large solar photovoltaic parks, industrial electrical installations;

Energy saving is our natural home where we move perfectly at our leisure !!!


Today, the company’s ownership has 10 years of experience in the energy sector. From 2007 to 2010, carrying out engineering services (work management, work manager, CSE, design, etc.) at most wind farms in Sicily and, since 2010, implementing renewable energy production facilities (photovoltaic, solar thermal, LED relamping) as General Contractor.

At the peak of expansion, on June 30, 2012, in a single day, nine plants were connected at a time, with a total power of about 950 kwp.

These skills have, of course, been transferred to Italtekno s.r.l. which, since January 2017, has become the natural development site of the industry.

The fundamental step of this change was the creation of the ESCO.ONE brand and the transformation of a company that simply produced renewable energy production facilities to a top-level energy-efficient company or an Energy Service Company.

At the completion of the growth and transformation process, the company, in July 2017, following audit by Bureau Veritas, was certified under UNI CEI 11352: 2014.

Today, we focus all of our strength, apart from the usual realization of plants, energy efficiency, consumer monitoring, energy diagnosis and audits, white certificate management, and realization of Project Finance under art . 183 paragraph 15 of Legislative Decree 50/16 (New Procurement Code).

The company consists of a technical office, a commercial office, teams of highly qualified installers and professionalism at your service.
