St. Louis, MO, U.S.A. --- (METERING.COM) --- December 13, 2007 – Distribution Control Systems, Inc. (DCSI), a subsidiary of ESCO Technologies Inc. and a member of the ESCO Communications Segment, which also includes Hexagram Inc. and Nexus Energy Software, has announced the successful delivery of version 3.0 of its TWACS NG™ software to one of its primary customers, PG&E.

TWACS NG 3.0 (formerly referred to as TNG 3.0) is the company’s most robust version of its state-of-the-art advanced metering infrastructure (AMI) software. Version 3.0 is a highly scalable, web-based software solution used in conjunction with the company’s powerline based TWACS® AMI system. It was developed to allow utility customers to successfully manage hourly and interval data from up to 10 million metering endpoints. Based on rigorous testing and metering endpoint simulation to date, 3.0 has been validated to confirm reliable scalability for up to 6.5 million endpoints, which will satisfy the majority of utility customers’ requirements worldwide.

In addition to its scalability, 3.0 also provides the industry’s most advanced outage detection and management system by continually triggering proactive real-time outage polling at the substation level. If an outage is detected, which in some cases is before the consumer is even aware of the service interruption, the exceptions are processed and delivered to the utility’s outage management system through an enabled Common Information Model (CIM) interface. This advanced functionality provides system-wide notification and scope determination to allow the utility to improve its outage handling and customer service information, while more effectively dispatching field resources to the root cause, which reduces customer disruption time.

Version 3.0 adds several functional enhancements to the comprehensive feature set already found in the earlier delivered versions of TWACS NG (i.e.; versions 1.6.3 and 2.0) including:

  • The ability to remotely download firmware to substation equipment and metering endpoint devices, ensuring that the TWACS system being deployed is ‘future proofed’ and can be upgraded with additional enhancements as required. This feature is being used at scale at several large customers.
  • An advanced AMI network and endpoint simulation tool that verifies the scalability to meet the needs of the largest utilities, both domestically and internationally.
  • Improved load-control and demand side management functionality based on the current TWACS load-control system.
  • The ability to effectively integrate with diverse software applications existing within the customer’s current management information technology infrastructure.
  • User-configurable software that efficiently handles the high volume and frequent meter readings required for widespread time-of-use or critical peak-pricing programs which allows for the effective management of energy operations.

Vic Richey, ESCO’s Chairman and Chief Executive Officer, commented, “We are extremely pleased with the delivery of 3.0 to PG&E, as well as the overall performance and scalability of our AMI software solution. TWACS NG has been one of the largest and most comprehensive investments that we have undertaken at ESCO, and to have finally reached this milestone in such a successful manner is very satisfying.”
