Most people today take electricity and the
infrastructure to deliver it for granted.
But it takes a lot of technical know-how to
get electricity to where you need it.

knows thE bEst, safEst and most EfficiEnt
ways to gEt ElEctricity to consumErs,
businEssEs and production facilitiEs.
The evaluation of cable vs. overhead line
transmission systems requires a comprehensive
study of technical, economical and
environmental aspects. Whereas in some
cases overhead lines are chosen as the most
cost-effective way of transmitting electricity,
cable solutions have to be taken into consideration
in cases of lack of aboveground space
or if the local topography does not allow for
overhead lines.
UnDErGroUnD cABlEs
If a customer’s power distribution project cannot
be achieved through aboveground cables,
it may be addressed through underground
cables. Pöyry is one of the few consulting firms
that have the special knowledge in the layout,
monitoring and operation of underground
cable systems.
cABlE rAtinG
Pöyry are experts in all aspects of cable
system engineering, especially in the field of
thermal cable rating. We can design cable
systems with or without thermal backfill, with
underground ducts or pipes and duct bank arrangements,
or with tunnels featuring optional
ventilation.
We offer a wide range of services regarding
cable installations for various conditions.

In the 100 years since
Pöyry’s founding,
many projects have
been r ealized in the
T&D sector. And in
multiple cases, we
a ttained our main goal:
Satisfied customers.
From our origins as consulting company
operating exclusively in our home market,
Pöyry today offers its s ervices internationally.
We have offices catering to our transmission
and distribution customers in a number of
countries, including Austria, Dubai, Finland,
Switzerland and Hungary. our international
expansion has not only increased our technical
competence, but has also taught us how to
provide our solutions and services in a variety
of circumstances unique to each country and
geography.
As an independent engineering concern, we
can handle:
• Grid connections of hydroelectric power
plants
• Grid connections of thermal power plants
• Grid connections of renewable power plants
• Transmission and distribution grid elements
(lines, cables, substations), and
• Substation rehabilitations

For governments wishing to incorporate more
energy from renewable sources, such as wind
power, into their existing power grids, these
grids must become ‘smarter’.
Pöyry supports the development and
implementation of smart grids today.
Smart grid technology offers enormous
potential for electrical transmission and
distribution operators, as well as other companies,
to respond to flexible demand in their
networks. Smart grids have the capability to
work together with, or independent from, large
conventional generators.
Pöyry can also provide assistance in forecasting
and mitigating the impact of peak
demands in cases where consumers simultaneously
react to time-variable price signals,
especially with regard to the expected boom
of electric vehicles. Dealing with increasingly
complex planning and operation of networks
in a ‘smart’ world, with load-flow inversion and
more dynamic demand, presents unique challenges
that we can address.
