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

Energy supply system for the industry (food & beverage)

PepsiMoscowRussia

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
