MAINTENANCE AND ELECTRIC POWER SERVICES BRANCH «ELECTRICA SERV» S.A.
Energy is the vital flux of civilization that any community needs. To maintain this
flux continuity, to take care that the energy reach wherever is needed is our
mission, Electrica Serv mission.
For being able to bring power supply to as many communities as possible we
streamlined; for being able to participate to the development of as many
companies and industrial platforms as possible we enhanced our profitability; for
being able to sustain transport infrastructure modernization, from highways to
airports, we reorganized our activity.
We adapted to the business environment, we became better and stronger and we
are moving forward! We are Electrica Serv and every day ...energy depend on our
hands.
Our Vision: Electrica Serv is one of the most powerful and competitive suppliers for
electric power services in Romania, aiming to become an important competitor on
the extern market.
Our Mission is to perform high quality services, which should meet the
requirements of all clients’ categories, aiming to provide permanent power supply
to the electrical energy consumers, in a context of maximum efficiency and
environmental protection.
Our main activity: Electrica Serv’ main object of activity is to execute maintenance
and repair works for power distribution and transport grids and installations (110
kV); to supply various services and to perform investment works in the energy
sector.
Electrica Serv History
S.C. Maintenance and Electric Power Services Branch Electrica Serv S.A. is legally, a
dynamic structure. It benefits of more than 120 years expertise performing, under
various organizational structures and shapes, maintenance works and services for
the energy sector, since the beginning of its development.
 2001: the separation of the electrical power distribution and supply activities from the
maintenance, repairs and support activities within Electrica S.A. take place based on HGR
1342/2001; the Maintenance and Electric Power Services Department coordinating 8
Maintenance and Electric Power Services Subsidiaries at regional level is established
within Electrica – S.A.
 2005: the maintenance and support activities are completely externalized pursuant HGR
74/2005; the ninth branch, legal entity of Electrica – S.A., named S.C. Maintenance and
Electric Power Services Branch Electrica Serv - S.A. is founded.
 2012: Electrica Serv is reorganized with only 3 subsidiaries (SISE Electrica Transilvania
Nord, SISE Electrica Transilvania Sud, SISE Electrica Muntenia Nord) based on HGR
760/2010; five new maintenance and electric power services legal entityes result in Banat,
Dobrogea, Moldova, Oltenia and Muntenia areas, with Electrica – S.A. as unique
shareholder.
Electrica Serv Structure
 From a structural standpoint, Electrica Serv is conceived so that it should cover
with priority the volume of works necessary for the maintenance and the
development of the power grid and power plants, on the NV, central and SE
Romania.
 This thing is possible due to its developed and complex territorial infrastructure,
based on 3 Maintenance and Electric Power Services Subsidiaries (SISE) with
Maintenance and Electric Power Services Agencies at county level, zone centres
and working points.
We Sustain the Quality in the Energy Sector
 Electrica Serv conducts its business with respect to legislation, standards and regulation
regarding The National Power System security. Electrica Serv is certified by ANRE for
designing and execution works in the energy sector.
 Quality confirmation of Electrica Serv products and services is given by SRAC and IQNet
Certification with regard to the Integrated Management System - Quality, Environment,
Occupational Health and Security, according to the standards SR EN ISO 9001:2008,
14001/2005 and OHSAS 18001/2008. The continuous enhancement of the Integrated
Management System - Quality, Environment, Occupational Health and Security was
defined as a strategic objective for Electrica Serv. The organization’ concern to ensure a
high quality level for its services, to prevent and limit the environmental aspects with a
significant impact and the aspects which would cause the occurrence of work accidents is
manifested in all its activities.
