REE is the Spanish transmission system operator (TSO) responsible for the transmission of electricity nationwide, including the Canary and Balearic islands. Its 800-site network is used to control and manage a nationwide transmission grid.
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 IoT-based asset management to managing distributed energy resources such as rooftop solar and residential power storage.
Services supported by the Nokia network include sub-station communications, low-latency communication of IoT sensor data for measurement, protection and control, and time synchronization of devices. The network will also support operational control systems such as SCADA (supervisory control and data acquisition) and line protection, as well as synchrophasors (PMUs - phasor measurement units), which are one of the key applications for enabling highly accurate and dynamic analysis of the state of an electrical system. This is an important capability in smart, distributed energy grids, especially with intermittent power sources such as renewables.
