The Customer
Commonwealth Edison (ComEd)
About The Customer
Commonwealth Edison (ComEd), a unit of Chicago-based Exelon Corporation, provides electrical service to more than 3.8 million customers in Chicago and northern Illinois, operating as the state’s largest electrical utility.
The Challenge

With the passage of Energy Infrastructure Modernization Act (EIMA), ComEd was required to improve its overall system reliability. In order to reach the goals outlined in the law, ComEd decided to leverage a common network for multiple applications, including advanced metering infrastructure (AMI), distribution automation (DA) and smart city programs. With a modernized communications infrastructure, the utility would be able to increase grid reliability by identifying problems faster, optimizing business processes, automating problem resolution and reducing truck rolls.

The Solution

1. Advanced Metering (AMI) Solution ComEd’s integrated AMI solution provides two-way communications between customers and ComEd, enabling applications such as automated billing, remote disconnect and connect service operations, a customer web portal with near-real time consumption information, AMI-based outage management, meter hazard discovery, revenue assurance and dynamic pricing. 2. Distribution Automation (DA) Solution ComEd is implementing a five-year DA plan to improve outage management through better targeting of restoration crews to fault locations, enhanced asset tracking and faster power restoration through the automatic detection of faults and rerouting of power around the faults. 3. Small City Solution In 2015, ComEd began extending the use of its mesh network to support a smart street light pilot for 750 of the 176,000 ComEd owned fixtures in the Chicagoland area. The program equips energy efficient LED lighting fixtures with Silver Spring’s wireless monitoring and controls, leveraging the same smart grid network infrastructure used to support AMI and DA.

Case Study
Automation of the Oguz-Gabala-Baku water pipeline, Azerbaijan
The Oguz-Gabala-Baku water pipeline project dates back to plans from the 1970’s. Baku’s growth was historically driven by the booming oil industry and required the import of drinking water from outside of the city. Before the construction of the pipeline, some 60 percent of the city’s households received water for only a few hours daily. After completion of the project, 75 percent of the two million Baku residents are now served around the clock with potable water, based on World Health Organization (WHO) standards. The 262-kilometer pipeline requires no pumping station, but uses the altitude differences between the Caucasian mountains and the capital to supply 432,000 m³/d to the Ceyranbatan water reservoir. To the people of Baku, the pipeline is “the most important project not only in 2010, but of the last 20 years.”

Case Study
GPRS Mobile Network for Smart Metering
Around the world, the electricity supply industry is turning to ‘smart’ meters to lower costs, reduce emissions and improve the management of customer supplies. Smart meters collect detailed consumption information and using this feedback consumers can better understand their energy usage which in turn enables them to modify their consumption to save money and help to cut carbon emissions. A smart meter can be defined in many ways, but generally includes an element of two-way communication between the household meter and the utility provider to efficiently collect detailed energy usage data. Some implementations include consumer feedback beyond the energy bill to include online web data, SMS text messages or an information display in consumers’ premises. Providing a cost-effective, reliable communications mechanism is one of the most challenging aspects of a smart meter implementation. In New Zealand, the utilities have embraced smart metering and designed cost effective ways for it to be implemented. The New Zealand government has encouraged such a move to smart metering by ensuring the energy legislation is consistent with the delivery of benefits to the consumer while allowing innovation in this area. On the ground, AMS is a leader in the deployment of smart metering and associated services. Several of New Zealand’s energy retailers were looking for smart metering services for their residential and small business customers which will eventually account for over 500,000 meters when the multi-year national deployment program is concluded. To respond to these requirements, AMS needed to put together a solution that included data communications between each meter and the central data collection point and the solution proposed by Vodafone satisfied that requirement.

British Gas Modernizes its Operations with Innovative Smart Metering Deployment
The UK government has mandated that smart meters are rolled out as standard across Great Britain by end of 2020, and this roll-out is estimated to create £14 billion in net benefits to the UK in consumer energy savings and lower energy generation demand, according to the Oxford Economics report, “The Value of Smart Metering to Great Britain.” While smart-metering systems have been deployed in many countries, the roll-out in Great Britain is unique because it is led by energy retailers, who have responsibility for the Electricity and Gas meters. The decision to have a retailer-led roll out was made by DECC (Department of Energy and Climate Change) to improve customer experience and drive consumer benefits. It has also led to some unique system-level requirements to support the unique local regulatory model.
