Market Trends – Power Transmission & Distribution

LV substations are being connected to communication networks. Control techniques move into decentralized power generation to monitor almost 100% of all renewable power producers, starting from 100 KW and even down to 30KW

Power Transmission & Distribution Market

Virtual Power Plant (VPP) market increases from $5.2bn to $7.4bn by 2015 predicted by Pike Research

End-User

Ethernet, IP, MPLS replace SDH/SONET, higher throughput and lower OpEx for Smart Grid upgrades, new applications such as IP video surveillance, IEC 61850 IEDs. SG technology is not declining Powerline protocol is becoming an option for low voltage distribution systems. Merging Unit is disappearing.

IEC 81850 for HV/MV IEC 61850 for LV under preparation Companies establish own standards based on IEC 61000-4-18 to become mandatory in HV (400KV) substations e.g. in UK IEEE 1686 – security for IEDs

Local regulations e.g. BSI mainly for Smart Meter Data Product Approval required to get into RFQ’s from Utilities In DACH, requirements of BDEW white paper will be required as mandatory from all 4 German and Austrian TSOs

Regulations

Applications

SAVs and utilities are looking for vendors able to provide end-to-end solutions. Telecom equipment Suppliers want partnerships to move into Smart Grid, as strategic alliances/ frame agreements become more important. Existing infrastructure should provide 10 to 20 years ongoing lifecycle of substations.

Significant increase of data connectivity via mobile technology 3G/4G is expected primarily outside of DACH to build up back-up lines e.g in Russia/ Spain for LV substations Ethernet based IEC61850 is becoming the core standard in power systems. Security requirements are increasing for IP based substation communication due to more interconnected devices

Technology

Utilities and System Automation Vendors (SAVs) are responsible for specifying solutions, while SAVs will provide access to the substation automation market.
