State Grid Corporation

The State Grid Corporation of China has partnered with Nokia's Chinese subsidiary Nokia Shamgai Bell to upgrade grid communication systems and optimise the telemetry of grid and operations data.

The state owned utility is updating its optical network from an SDH network based 10Gbs to a packet/OTN network based on a 10Gbs.

The energy provider to more than 1.1 billion people or 88% of the Chinese population, in 26 provinces is adopting Nokia's 1830 PSS-32 platform to be the foundation of its optical transport network.

The new network will provide improved data capacity, efficiency and reliability in support of the State Grid Corporation of China's smart grid deployments in Beijing and Tianjin.

The need to upgrade the network rises from rapid growth of services in the utility's integrated data network.

The development is a measure by the utility to prepare itself to be a utility of the future, providing smart services including safer, cleaner, more economical and sustainable power.
The utility previously piloted Nokia's communications technology in Hebel, where the network is currently serving 100 million consumers of SGCC Jibel.

The 1830 Photonic Service Switch (PSS) portfolio consists of platforms optimised for varying optical network deployment environments, ranging from interconnecting data centers to efficiently scaling large metro, regional and long-haul optical networks.

The Nokia 1830 PSS-32 also provides intelligent and reliable network control and restoration through distributed GMPLS and/or centralised SDN control options for improved network capacity, efficiency, reliability and service deployment velocity. This will enable SGCC to deliver services rapidly, reduce network operating costs and extend network lifecycles.

Zhang Huijian, vice-general manager of SGCC Tianjin Electric Information & Communication  Corporation, said: "The new OTN network can provide better technology support for communications, deliver higher level of security and reliability for the power grid, and raise operational efficiency, while improving the business environment to help us deliver better services to our customers. We are pleased to be working with Nokia, which has advanced optical/IP technologies and provides high-quality and professional services to support us in this project."

Jin Jian, executive vice president at Nokia Shanghai Bell, head of enterprise & public sector, said, "We are very happy to be working again with SGCC to improve its core network, this time in Beijing and Tianjin. The new network will not only meet its capacity needs but will also improve efficiency and support a wide range of technologies that will be required as it make its electrical grid smarter."
