From meterpedia submission, and existing map data
Full deployment of significant programme started in September 2009 for Southern California (except Los Angeles).
5.3 million meters using less than 200kW.
Topography of supply points is mostly suburban with very few ‘rural’ sites.
Edison SmartConnect™ is SCE’s advanced metering program. The program has redefined the automated metering industry, and is a key component of Edison’s Smart Grid strategy, which brought Edison’s grid into the digital age for improved grid management operations.
Through advanced technology, Edison SmartConnect™ will provide SCE customers with new tools, services, and conveniences to help them make better about their energy use. The new “smart” meters will enable new pricing programs, and will provide customers with more information their energy use to help them save energy, money and reduce their carbon footprint.
Why? California’s peak energy use continues to grow. As a result, state energy agencies and are exploring ways to meet customers growing energy needs and offer incentives to conserve and shift usage away from periods of peak demand.
In 2004, the Commission (CPUC) directed (IOUs) to investigate implementation of an advanced metering infrastructure (“AMI”). AMI “smart” meters would allow customers to take advantage of dynamic rate programs, such as the “Time of Use” (TOU) rates available mostly to industrial customers. SCE analyzed available AMI technology at that time, and concluded that the limited functionality and operational benefits available at the time would not be cost-effective for SCE’s ratepayers. So, SCE set out to work with and technology vendors to develop a more advanced meter and communications system that would offer a cost-effective solution with added customer value and convenience. The result is SCE’s AMI network called Edison SmartConnect™.
SCE’s new “smart” meter and communications system will provide customers with more information their energy use, and with advanced tools and services to help them save energy, save money and reduce their carbon footprint. For example, “smart” meters will:
- Communicate personalized energy use information to customers through a secure wireless home area network and on the Web, helping customers make smarter energy decisions that will translate into savings.
- Enable new rate offerings to help customers save money by using less energy during peak periods and when energy prices are higher.
- Communicate with “smart” thermostats, appliances, electronics and solar panels in the home – pretty much anything you can plug in – enabling the programming of smart appliances and devices to respond to energy use preferences based on cost, comfort and convenience.
- Give customers the convenience of remote service turn-ons. If a customer is moving, for example, they no longer need to leave gates open, worry about pets, or wait for a field service representative.
SCE’s research and analysis support the narrowband decision as the best option to support a wide variety of functionality and ensure the program is cost effective for it’s customers. Here’s why:
While higher bandwidth seems appealing, it is not only more costly, but will provide wasted capacity. Simple data, not large data files, will be sent to and from the meter requiring no more than a narrowband connection. Energy pricing information will be sent via the narrowband connection.
Customer’s real-time energy usage and power quality information from the meter will be available securely over a narrowband wireless network.
The Edison SmartConnect™ communications system was designed to provide full program functionality and high-performance with a narrowband connection from the meter to the aggregation point, and a broadband connection from the aggregation point to the utility. The system was also designed for growth and flexibility to support advanced technology, prevent it from becoming “outdated” and result in long-term benefits for our customers.
Itron’s OpenWay AMI solution has been selected, and all meters will feature ZigBee connectivity for the HAN.
Secondary meter supplier to be selected.
January 2008 Interview with SmartConnect Leader
Jan 08 – Long web article/interview with the Director of SCE’s programme – key points:
- Have selected Itron Open Way for communication backbone
- Looking for non-Itron meter to use Open Way to maintain open approach
- Have selected HAN/local ZigBee platform, as fits best with requirements
- Considered 6loPAN, but believe it will not be ready for deployment in 2009 – states that 6loPAN could be flashed onto ZigBee chips in the future
- Every meter includes a switch to support potential prepayment services from 2013 – with bulk of functionality in the back office, but also to support demand management and improve outage and safety features
