Spain's REE selects Nokia for network upgrade [free access]

July 6, 2021


The Spanish transmission system operator (TSO) Red Eléctrica de España (REE), has selected Finland-based Nokia to upgrade its existing network with the latter’s internet protocol (IP)/multiprotocol label switching (MPLS) and dense wavelength division multiplexing (DWDM) optical technology.


The new IP/MPLS and optical transport networks from Nokia will provide significantly more bandwidth to the utility sector and its subscribers, and improve efficiencies. It will support a new generation of IP-based applications that will play a key role in everything from internet of things (IoT)-based asset management to managing distributed energy resources such as rooftop solar and residential power storage.


Services supported by the Nokia network include substation communications, low-latency communication of IoT sensor data for measurement, protection and control, and time synchronisation of devices. The network will also support operational control systems such as supervisory control and data acquisition (SCADA) and line protection, as well as synchrophasors (phasor measurement units), which are one of the key applications for enabling highly accurate and dynamic analysis of the state of an electrical system.


As reported, the core and aggregation networks will be based on Nokia’s IP/MPLS portfolio. The optical transport network, which replaces a legacy synchronous digital hierarchy (SDH) system, will use Nokia’s DWDM portfolio.
