The Piedmont Municipal Power Agency (PMPA), a joint action agency formed by 10 municipal electric utilities in the northwest section of South Carolina, has chosen Tantalus as its smart grid communications provider.

Tantalus will provide load management tools and an advanced metering infrastructure (AMI) overlay, which will allow the group of South Carolina utilities to remotely read existing Itron electric ERT meter deployments.

In 2011, Tantalus partnered with Itron to offer an overlay solution to utilities with existing Itron ERT modules and one-way automatic meter reading (AMR) networks. According to Tantalus, the  joint solution provides a migration path to two-way AMI for utilities without requiring a comprehensive infrastructure upgrade. As a result, the company says, utilities can extend the value of their existing investments in AMR infrastructure while adopting the benefits of real-time smart grid communications.

PMPA selected the Tantalus Utility Network TUNet to extend a two-way AMI network to selected members during an initial deployment phase. The second phase will include all of PMPA’s member utilities, representing more than 100,000 endpoints.

PMPA will procure and maintain the smart grid communication network and load control devices for its members, and TUNet will also provide end-use consumers the ability to view their usage data over the Internet.
