Use of SSK in I&C Energo projects

The Cabling Management System (Systém správy kabeláže – SSK) is a specialized software tool to support the design,
implementation and operation of cabling systems for large technological systems, developed and used by our Company
for over 10 years.

Since 2007 the SSK system has been deployed in the Dukovany Nuclear Power Plant to provide complex management
of its cabling system, including operations from the design of modifications and upgrades to change management,
controlled documentation management and to the performance of various analyses and evaluations. Deployment in
the Dukovany Nuclear Power Plant is currently the greatest application of SSK. The system presently manages over
250,000 cables with a total length of over 17,000 km, or 16,000 cable routes with a length exceeding 180 km.

Based on its successful deployment in the Dukovany Nuclear Power Plant, the SSK system has been also used for the
complex management of the cabling system in the Temelín Nuclear Power Plant since 2012, with a similar scope of
operations and services provided.

Aside from applications in nuclear power plants, the SSK system was also used in the past to support the design and
implementation of cabling systems in conventional energy sources, specifically in complex renewal projects in the
Tušimice II Power Plant (2008–2013) and for the construction of new units of the Ledvice Power Plant (2009–2016) and
the Počerady Power Plant (2011–2014).
