History

CESI was founded in 1956, and has more than 60 years of experience in testing and consulting services for the electrical industry.
The strong necessity of doing experimental tests and network studies persuaded the big electromechanical industries, together with the majority of electrical industries, of the need of a “Great Power laboratory”.
In the early 50s, the “X Laboratory” was born. At the end of the 50s, CESI is developed a leadership in the determination of short-circuit powers inside the transmission lines and in load flows’ problems. In the 1958, its international aim is attested thanks to an important commission: the study of the system El Chocón Dam – Buenos Aires for the construction of two hydroelectric plants.
The problems of the unification of electrical frequencies and of the interconnection networks, enabling energy interchange between an “island” and another and consequently achieve Italian electrical system unity, lead to the establishment in 1962 of ENEL.
In the 1964, ENEL decided to use CESI’s laboratories to make targeted studies for its operative activity. The company purchased the majority of the capital of CESI.
CESI, under the boost of the increase in electricity consumption, built new laboratories, also for high voltage cable tests.
This gave birth to the “1000 kV’s Project”, which was realized for the transport of energy and high voltage on the Italian electrical networks. The “1000 kV’s Project” was a key step in the history of electrical industry’s research, not only in Italy but also in the world.
In 1988, CESI signed a convention with IMQ which bring to fruition the CSQ.
At December 1989, ENEL charged CESI with a research project to be finished in three years: the Energy storage for a stationary and vehicular use. The topic was the application of the electrical battery not only on traditional power plants but especially on non traditional ones, like photovoltaic and wind power. The project faced off the development and industrialization of pioneering batteries and, at the same time, wanted to realized prototypes of electric vehicles with a highest degree of innovation.
In 2002, CESI acquired the Piacenza’s laboratory from ENEL Produzione, which has integrated and extended the offer of monitoring systems for thermoelectric plants during the operation and maintenance. In addition, the company got the hydraulic and structural pole from ENEL; ENEL Hydro S.p.A. which delivers services for hydroelectric power plants.
ISMES was purchased in 2004 and, thanks to the deal, CESI increased its competences in land conservation, natural hazards and qualification of civil structures and industrial plants, preservation of monuments and monitoring services.
2005 saw CESI's expertise in laboratory testing being extended through the acquisition of IPH GmbH and FGH Engineering & Test GmbH from Vattenfall Europe. Both companies are working in the field of testing of high -, medium - and low voltage electrical components. CESI Ricerca created in 2005 with ENEA, and it has been transferred into GSE in 2009.
With a view to cater closely to international client needs, CESI established two new companies: CESI Middle East was set up in 2011 in Dubai and CESI do Brasil in March 2012.
On February 2012, CESI Middle East has been contracted by the Kuwait-based Arab Fund for Economic and Social Development to come up with a plan for integrating the loosely connected electricity and natural gas networks of 20 Arab countries.
CESI is a founding member of RES4MED, an association that aims to increase renewable energy sources penetration and to analyse the conditions for integrated electricity markets in the Mediterranean area.
On 30 December 2019, CESI has acquired the property of KEMA B.V. from DNV GL. The acquisition includes all the high voltage testing, inspection and certification activities carried out at the KEMA owned laboratories in Arnhem and Prague. The transaction was completed on March 2, 2020 with the acquisition of the Chalfont laboratory. The KEMA testing and inspections facilities include the world’s largest high-power laboratory, with the highest short circuit power of 10,000 MVA, and the world’s first laboratory capable of testing ultra-high voltage components for super grids, as well as the Flex Power Grid Laboratory, for advanced testing of smart grids components

Organizational structure

The company has three business divisions:
CESI proves its competence as an independent testing service provider also by its accreditation certificates:
