"We look forward to getting this project underway as we continue to increase the efficiency and functionality of our electricity grid over the coming years."

Guyana's deployment is the first international joint project between Tantalus and Itron since the two companies announced an alliance in late 2011.The strategic alliance combines Itron's SENTINEL® and CENTRON® electricity meters as well as its electric, gas and water ERT modules with Tantalus' comprehensive communications network, TUNet®, the Tantalus Utility Network, to reach public power utilities in North and South America. Uniting the capabilities of TUNet with Itron's electricity meters has allowed the companies to offer a joint solution that accommodates smart metering, demand response and distribution automation for international markets such as Guyana.

"We've been strategic in our expansion into international markets that recognize the full range of possibilities that can be achieved from robust two-way communications networks and smart metering," said Tantalus CEO Eric Murray.
