Nokia powers the grid in China for the world’s biggest utility company

Powerline

Late last week, Nokia announced that the State Grid Corporation of China (SGCC), the largest utility company in the world, will deploy an optical network using Nokia’s IP/Optical solutions.

The deployment will allow SGCC to expand network coverage, while also increasing capacity and flexibility, said Nokia. New deployments in Hebei, Hunan provinces and Chongqing municipality, as well as expansions in ten other provinces, including Jibei, Jiangsu and Sichuan will be possible due to this project.

SGCC supplies electrical power to more than 1.1 billion people across 26 provinces, covering 88% of Chinese national territory. SGCC is upgrading the communications infrastructure to monitor and control the largest utility grid in the world, producing and transferring massive amounts of data across long distances.

The deployment leverages Nokia’s WaveFabric optical solutions to a future-proof network for critical and non-critical services, according to Nokia. The solution also provides the provincial backbone with bandwidth to connect high-voltage power stations and substations along the electrical power transmission line.

Optical networks provide a more reliable, faster and higher bandwidth network for data transmission compared to traditional communication solutions with wire cables. Reliable and resilient networks allow for real-time decision making and enhance operational productivity, which is key for outage management.

SGCC and its customers will benefit from:

  • A Nokia optical network that can be upgraded to much higher capacity/reliability and is ready for smooth TDM and packet evolution to protect network investment.
  • With the Nokia 1830 Photonic Service Switch (PSS) WDM/OTN, the SGCC regional backbone can be optimized for high capacity, multi-service support, and resilience, also ready for OTN sinking extension in the future.
  • Improved and efficient control of operations via an application management tool that enables access control, real-time performance monitoring, an intuitive alarm display, more customized reporting, efficiency improvement and a local language user interface.

Markus Borchert, President of Nokia Greater China, said: “This expanded partnership with State Grid Corporation of China is a milestone for Nokia’s optical portfolio. Data-driven insights are key to SGCC’s overall digital transformation as it looks to deliver safe, reliable electricity for more than 1 billion people.”
