6. Communications Technologies (WAN) - Cons Pros Description Type Fast communication, good for always on -Smart Grid applications. High bandwidth applications which can even deliver internet services. RF networks (esp. MESH) for last mile communications. networks are cost effective in areas of high density. Secure connection to the meter. Can use existing wires infrastructure. Data concentrators can act as mini RTUs for smart grid. Availability & basic 2G Coverage is good. Typically supports IP connection and can do always on. Broadband IP communication either via cable/ Licenced/unlicensed RF radio modems to a concentrator device. Power Line Carrier uses the incoming electricity cable to transmit a carrier signal. FSK and OFDM are two of the main standards. More typical were Distribution Company owns the meter. Use of GSM based technologies in metering is common. They use the ‘public’ communications 2G/3G network. Relies on always on secure infrastructure such as broadband or 4G network in place. Currently available unlicensed frequencies are limited output power and this can cause shadow areas. This solution is not good for rural areas where houses are spread out. Communications are disrupted by walls/obstacles. No global standard Propriety protocols are common. low bandwidth. Takes time to collect data from each meter Not all technologies can penetrate the LV transformer. QoS is not typically guaranteed. Cells are limited on number of connections. Data rates are lower on 2G and setting up a connection can take 30 seconds or longer. Not good for broadcast IP / 4G WiMax LTE Low power Radio / RF MESH PLC GSM/ GPRS/ HSPDA

Agenda
The average transformer age is approx. 40 years old, well past design life and the average utility worker. By 2010, one in three workers will be age 50 or older Utility executives estimate ½ of the technical workforce will reach retirement age in 5 – 10 years At 50+, utility craft workers have highest average age of any industry Capacity contraints
This is the 2 way connection from each metering location to the back office system. This may include direct connections or via concentrators or combination of more than one. Below is a comparison of the technologies and where GE Energy is currently planning products over the next 12-24 months.
End-to-end architecture; key points: Telecom proven policy-based networking will enable the Smart Energy Grid (a self-sensing, self-adaptive, self-healing network) Based on leading Utility Standards (IEC CIM), enables easy integration with legacy and emerging Utility operational and business support systems
