Utilities have found TWACS technology to be cost-effective and reliable in installations of all sizes. It is known for its effectiveness in rural areas where population is spread out or in areas with rough terrain, but it has also been successfully deployed in urban environments. PPL Electric Utilities, Wisconsin Public Service, and Idaho Power are utilities with rural and urban mixes that have effectively deployed TWACS AMI systems.

The technology employs existing power-line infrastructure to deliver industry-leading read rates over 99 percent as reported by customers.  Its technology seamlessly integrates into existing substations without adding additional points of failure to the system such as towers, repeaters, or line conditioners.

In addition, Aclara invests heavily in research and development to ensure that its technology continues to meet customers' increasing demands. For instance, recent developments in the technology employ concurrency and multiplexing to deliver the bandwidth needed to handle millions of meter data points without the latency issues of some mesh radio-frequency technologies.

"TWACS technology has proven to be one of the most durable and effective AMI systems in existence today. Customers deploying TWACS are extremely loyal to the system and our research and development team has made steady improvements designed to address the expanding requirements of our customers," said Gary Moore, chief operating officer of Aclara.  "We see continuing growth in the deployment of TWACS technology well into the future."
