Redwood City, California, May 2, 2007 – Trilliant Incorporated, the industry's leading provider of advanced metering infrastructure (AMI) based on open standards, today announced the availability of the Micro Access Portal (MAP) for ZigBee, an extension of Trilliant's advanced wireless mesh network offering into home automation networks (HAN) using ZigBee.

Like other Trilliant mesh devices, this ZigBee-based energy service portal device can be embedded into a wide-range of utility owned or managed components including meters, smart thermostats, in-home displays, remote appliance controller switches, or outdoor devices providing secure 2-way communications and control. The end-to-end AMI-HAN solution incorporates ultra-secure encryption/authentication and includes advanced software for consumer messaging, home management and load control. By using Trilliant's advanced mesh architectures utilities can deploy supplier-neutral demand response solutions that include interconnection of load-bearing consumer appliances and information displays with meters and system control centers.

"Trilliant has been an active member in the ZigBee Alliance and a leader in the delivery of wireless networking solutions for utility applications," said Bob Heile, chairman of the ZigBee Alliance. "Customers are served by the broad range of solutions offered by a long list of major manufacturers serving the energy market who use ZigBee to deliver innovative solutions."

Trilliant provides the industry's first end-to-end solution for unified AMI-HAN based entirely on IEEE 802.15.4 standards. The Company is the first AMI supplier to deliver a standards-based platform for AMI and demand response (i.e., load control) incorporating thermostats and other loads such as pool pumps and water heaters. The solution also supports in-home consumer displays that control loads, display meter readings, and provides for utility initiated messages.

"Our holistic approach improves consumer participation in a dynamic energy economy", said Geoff Williamson, chief marketing officer for Trilliant. "Home energy management through a unified access point is a critical infrastructure component providing in-home users the control they seek and utilities the easy-to-manage delivery they want. We enable the MAP to reside in any intelligent device, be it a meter, thermostat or display," continued Williamson. "This supports the varied economic preferences and demand patterns of the participants within our industry. We believe that single-source and proprietary approaches are not realistic given the diversity of this expanding market."

Trilliant's MAP solutions have been architected to provide compatibility-assurance and are remotely upgradeable to maintain compliance with evolving standards. These offerings are an extension of Trilliant's AMI and demand response solutions providing cost effective, high performance and highly reliable 2-way wireless communications for utility applications.

Availability
For utilities considering wide-scale AMI initiatives with unified demand response, Trilliant's MAP solutions are available now for evaluation-quantities with mass volume scheduled for Q1 2008.
