The Commission has approved the
General Technical High-voltage Requirements developed by transmission system
operator Litgrid AB, taking into account the requirements of the European
Commission Regulation establishing a network code on requirements for grid
connection of high voltage direct current systems and direct current-connected
power park modules.
These requirements include
frequency stability, reactive power and voltage requirements, network
characteristics, and so on. They will be applied to new high-voltage power
plants connected to the transmission network, ensuring reliable and safe
operation of the transmission system. If the high-voltage power plant does not
meet these requirements, the transmission system operator may refuse to connect
it.
These requirements do not apply
if the connected power plant voltage is lower than 110 kV and / or is located
on islands whose energy system is not synchronously connected to the
synchronous zone between mainland Europe, Great Britain, Northern Europe,
Ireland and Northern Ireland or the Baltic.
