Getting Amped Over Internet Meter Reading

The Challenge:

Find a more effective alternative to reading electric meters via dial-up modem. Add remote meter reading capabilities for gas and water meters for a more uniform and streamlined process, improved data accuracy and lower cost.

The Solution:

With the Lantronix UDS100 device server and Automated Energy’s iMETER software, the City of Palo Alto Utilities found a seamless solution that enabled their utility meters to be managed via the Internet.

The Benefit:

The pilot network solution enabled the City to fully utilize meters already in the field with a single reading process while potentially achieving an improved level of monitoring and service for its electric, water and gas utility customers.

Automated Energy has built a reputation as a company that empowers business and government agencies with the tools to evaluate and understand their energy consumption. During the 2001 rolling blackouts in California, Automated Energy consulted with utility companies to create commercial demand reduction programs (DRP) which worked real-time to alert when power draws in a certain area became too heavy. With the DRP, power could be reduced or shut off, or transferred from one area to another allowing energy costs to be adjusted in real-time. One of the biggest challenges in this process was working with the telephone companies for dedicated lines to each meter with an individual phone number for every customer purchasing the DRP system.

The Situation:

Integrate Dial-Up And Manual Metering Systems Into A Uniform System Over Fiber

The City of Palo Alto Utilities consulted with Automated Energy to find a solution for effectively enhancing its existing Advanced Metering program using the city’s fiber network. The major challenge was that the city had two different meter-reading systems: a dial-up modem system for reading electric meters and a manual system for reading gas and water meters. The city’s meter shops had been using telephone-based communications and devices on an as-needed basis for load research and customer requested information. Palo Alto has a dark-fiber utility, so that utility data can be shared over its fiber network. The City’s goal was to pilot test a means to obtain timely building metered data while eliminating the need for dial-up communication in selected sites.

aeThe Solution:

Automated Energy’s iMeter And The Lantronix UDS100

Together, they determined this problem could be solved with Automated Energy’s iMETER. This Remote Reading Application enables users to retrofit existing Interval Data Recording (IDR) meters to communicate over the Internet and eliminate additional dial-up lines, tying up valuable phone lines and avoiding the risk of missed data.

To provide the network connectivity, Automated Energy turned to the Lantronix UDS100 device server. An ideal modem replacement, the UDS100 provides a quick, simple and cost-effective way to bring the advantages of data accessibility and remote management to equipment not currently connected to a network. Using a method called serial tunneling, the UDS encapsulates serial data into packets and transports it over Ethernet.

“To meet the City’s needs, we needed to combine the merits of our iMETER solution with a robust networking solution,” said George Bell of Automated Energy. “Lantronix offered the necessary connectivity with technology that wouldn’t interfere with the way the City’s connected devices already worked. The end result is a compatible pair of technologies that work together seamlessly.”

The City of Palo Alto Utilities then conducted a trial of this solution at Palo Alto City Hall to read the electric, water and gas meters via fiber. The meters were connected through the UDS100, providing the ability to be specially configured for use with the meter communications protocol, thus allowing users a more efficient way to remotely monitor, manage and share connected devices over a network or the Internet. Palo Alto just needed to provide a local area network (LAN) to connect to a local switch or the Internet.

The Result:

Simplified And Improved Service Using Existing Infrastructure

With this solution, the City of Palo Alto Utilities was able to successfully pilot a robust and reliable channel of data communications that can potentially eliminate meter reporting issues commonly due to communications errors and problems with phone lines. In addition, this pilot program proved the ability to eliminate the cost of dedicated phone lines and costs related to managing those lines. By preserving the existing meter and network infrastructure and simplified service, this solution provided a method to be able to easily adapt to new market requirements such as RTP, DRP and others.

“As a pilot project, we have been able to successfully demonstrate that we can read our electrical, gas and water meters at City Hall using our dark fiber backbone as a communication backbone,” said Tom Auzenne, assistant director, Utilities Administration Services for the City of Palo Alto. “In addition, this project allowed us to utilize the Internet as the medium to access the meter data quickly and easily.”

Automated Energy is currently working with three other major utility companies to implement a similar ASP program based on the Ethernet-enabled IDR meter technology. “There is a huge potential here,” says Automated Energy’s George Bell. “As utilities realize the benefits of eliminating telephone lines and managing their meters over the Internet, the demand will continue to grow in electricity, water and gas. PG&E, for example, has approximately 4,000 IDR meters in place currently, and there is a strong push from the State of California to implement real-time market value pricing.”
