Swiss electricity transmission system operator Swissgrid has deployed IP/MPLS and optical communications to securely and reliably monitor and switch its transmission gridThe communications hardware is provided by Finnish multinational communications and information technology company, Nokia.
Swissgrid’s Grid Control Network, into which Nokia’s communications technology has been integrated, interconnects power plants, data centres and offices.
The transmission operator currently run s 6,700 km and connects 140 substations.
[quote] According to a company release, Nokia performed turnkey implementation of two IP/MPLS -based networks, one an operational network and the other a business communications network. Both networks are said to be overlaid overlaid on an encrypted DWDM and CWDM network. The operational and business communication networks leverage Nokia’s 7705 Service Aggregation Router and 7750 Service Router portfolio, as well as the company's 1830 Photonic Service Switch.
The operational network supports Supervisory Control and Data Acquisition (SCADA) systems, teleprotection, video surveillance via closed-circuit TV, site access control, and intrusion detection. The communications network on the other hand, enables communication between substations and Swissgrid locations for office LAN and voice over IP (VoIP) requirements.
The operator runs the Grid Control Network from a pair of Grid Control data centres that are connected via encrypted, redundant DWDM wavelength services.
When the Grid Control Network is fully deployed in partner sites outside of Switzerland, the new infrastructure will help enable exchange of electricity between Swissgrid's network in Switzerland and sites in Germany, Austria, Liechtenstein, Italy, and France.
North Sea countries to boost energy cooperation
North Seas region countries (Belgium, Denmark, France, Germany, Ireland, Luxembourg, the Netherlands, Norway and Sweden) have agreed to further strengthen their energy cooperation.[European transmission R&D priorities for 2015-2017]
According to the European Commission’s website, the aim of the agreement is to create the conditions for the development of offshore wind energy in order to ensure a sustainable, secure and affordable energy supply in the North Seas countries.
EU Commissioner, Arias Cañete, said: "Today marks a turning point in cooperation in the North Seas region. We now have a concrete action plan that will deliver results. This strategy will boost interconnection and renewables capacity, help fight climate change and bolster energy security, which are the central goals of the Energy Union."
