Nokia replaces SDH with IP/MPLS and DWDM for Red Electrica
Nokia says it has won a contract to upgrade the SDH network of Spanish electrical transmission company Red Eléctrica de España (REE). The systems house will supply IP/MPLS and DWDM technology for the purpose.
REE uses its 800-site network to control and manage a nationwide transmission grid that also covers the Canary and Balearic islands. The IP/MPLS and DWDM upgrade will provide more bandwidth for these purposes as well as support a new generation of IP-based applications, including IoT-based asset management and managing distributed energy resources such as rooftop solar and residential power storage. The fiber network also will support sub-station communications; low-latency communication of IoT sensor data for measurement, protection and control; and time synchronization of devices, as well as operational control systems such as SCADA and line protection and synchrophasors that enable accurate and dynamic analysis of the state of an electrical system.
The DWDM fiber network will support wavelengths of up to 100 Gbps. Nokia’s Network Services Platform (NSP) will support network operations.
“REE is a key player in the energy transition and the challenges we face are clear, and we must be able to anticipate them, so we need to have the best tools with which to carry out our mission with the highest possible quality, safety, and efficiency,” commented Manuel López Cormenzana, director of transmission infrastructure maintenance at Red Eléctrica de España. “In this sense, modernizing our communications network is vital in order to advance in the digitalization of our processes and to enable advanced management of transmission assets.”
“We have worked closely with REE for several years to prepare for this migration, culminating in a successful proof of concept in 2019. Our work with European transmission system operators enables us to ensure that REE’s network will interwork seamlessly with continental systems – a key capability in the shift to renewables and our ability to manage intermittency across the region,” added Patrick Langelaan, head of enterprise in Southern Europe at Nokia. “This win reflects Nokia’s ongoing commitment to the energy sector and our collective journey to a de-carbonized, electrified future.”
