Tailored systems and solutions for utilities,industry and infrastructure
Regional customers
Our maintenance-free and compactgas-insulated switchgear supportutilitiesin building more cost-efficient and reliable grids, as well asin integrating into smart grids.
For wind farmsand turbines, ourbusbar trunking systems and medium-voltage switchgear are used, ensuringa reliable connection to the powergrid. Energy storage solutions enable
the integration of an increasing num-ber of wind turbines into distributiongrids, without requiring that such gridsbe expanded immediately.
Modern infrastructure, such as hospi-tals, office buildings and airports, mustmeet stringent requirements in termsof safety, low environmental impact,and integration of renewable energy.Our low- and medium-voltage switch-gear and busbar trunking systemsensure a high level of safety, flexibility
and functionality.
Globally operating customers
and EPCs
In the oil and gas industry or inmining, for example, our prefabri-cated solution in a container featuresefficiency, safety and reliability forsupplying power under extremelydifficult environmental conditions. Itgives you an efficient and economicalalternative to conventionally installedmedium-voltage substations.
Chemical productionmust be
supplied with power around-the-clock on a cost-efficient yet extremelyflexible basis. With our switchgear,we offer you an efficient and reliableenergy supply.
In the automotive industry and indata centers, busbar trunking systemsoffer a stable electrical infrastructurewhile providing flexibility for the con-nection of loads in case of subsequentmodifications or expansions.
In the metal industryor in the pulpand paper industry i.e., whereverlarge amounts of energy are requiredon demand and peak loads need to bereduced our energy storage systemoffers the right solution.
Maintaining the balance
between economy andecology with continuing
globalization these are
challenges that the majority
of industries faces today.
Flexibility is becoming more
important, development
cycles are becoming shorter,
and time-to-market is
becoming crucial.
Your business success is
based on a reliable and
flexible energy supply.This results in high
demands on suppliers of
electrical systems and
solutions.
Whether in the supply of
cities and infrastructure, or
for industrial plants with
Siemens systems and
solutions you will always
have the right solution for
a reliable and cost-efficient
energy supply whetheryou are operating regionally

Energy storage in power distribution
ENEL S.p.A.MoliseItaly
Energy storage system for
studying new smart grid
solutions for ENEL in Italy
Requirements As one of Europes largest utilities, Enel invests heavily in the integration ofrenewable energies into the power grids. Due to the highly distributednature of the multiple renewable energy sources it is necessary to takeaccount of the fluctuating feeds, and offset the effects to ensure a stableand high-quality supply for their customers.
Solution In February 2012, a SIESTORAGE energy storage system was put intooperation with a power of 1 MVA and a capacity of 500 kWh.SIESTORAGE helps ENEL to offset load and voltage fluctuations withinmilliseconds. The system act s either as an additional source of energy,
or absorbs peaks in generation. It is not necessary for large power plantsto intervene.
Value added Improved system availability and safety of all machines and devicesconnected to the grid
System availability is maintained at 95% capacity during the maintenanceof individual battery modules
Faster restarting of the system with black start capability
Busbar trunking systems and low-voltage switchboards in infrastructure
Sddeutscher VerlagMunichGermany
Low-voltage power distribu-
tion for an office building
of the Sddeutscher Verlag
in Munich
Requirements Planning of the new group headquarters included the development of apower concept that went far beyond the requirements of the energy-savingregulations applicable at the time. The concept also fulfilled the clientsrigorous requirements in terms of sound insulation.In addition, the building and building services were to be flexibly adaptableto fast-paced changes in the publishing and editorial industry.
Solution Integrating the aspects of cost-efficienc y, sustainability and fire load, theplanners chose to use a modular and space-saving SIVACON S8 low-voltagepower distribution board as well as SIVACON 8PS busbar trunking systems forpower transportation and distribution up to the storeys. The busbar trunkingsystem also forms the basis for the integrated overall concept from Siemens.
Value added Harmony between cost-efficiency, sustainability, building efficiency, andflexibility of use
A productive work environment with a room climate that can be adjustedby the occupants

Low- and medium-voltage
power distribution for Pepsis
iced tea filling facility
in Moscow
Requirements Pepsis iced tea filling facility on the south side of Moscow is one of the mostmodern plants in Russia, extending over a length of 300 meters. An impor tantrequirement for its smooth operation is a safe and reliable power distribution.Already in the planning phase, Pepsi decided for a uniform solution thatshould provide a high degree of consistency, reliability and flexibility.
Solution The overall low- and medium-voltage solution is based on the Totally IntegratedPower concept from Siemens. Using the planning software SIMARIS design,all components necessary for power distribution were dimensioned precisely,conveniently and quickly from the GEAFOL transformers and NXPLUS C
medium-voltage switchgear to the SIVACON S8 low-voltage power distributionboard and up to the SIVACON 8PS busbar trunking systems.
Value added Safe and standard-compliant planning with the software SIMARIS design
Optimally aligned products and systems
High flexibility with regard to changing requirements
