WELLESLEY, MA, June 4, 2007 – Nexus Energy Software, a subsidiary of ESCO Technologies (NYSE:ESE) today announced the availability of a hosted, "on-demand" Meter Data Management (MDMS) capability.

"Utilities looking to implement an Advanced Metering Infrastructure (AMI) are increasingly recognizing the need for a robust MDMS to serve as the central hub that manages, process, stores, and makes this newly available data available to other systems”, said David Bonnett, Vice President of Product Management at Nexus. "Until now, there have been limited or no choices for smaller utilities that cannot afford a large-scale MDMS, or for utilities that are implementing pilots but are not ready to commit to long-term MDMS deployment. A hosted, on-demand platform meets these needs."

Jon T. Brock, Chief Operating Officer at research-based consultancy UtiliPoint International, supports this concept. "We have been hearing from utility executives across the country that they would be interested in a hosted MDMS solution, either for the long term or as an interim solution while their longer term plans are being formulated. Nexus' new offering appears to plug an important gap in the market."

Nexus Energy Software is a leading provider of MDMS systems, including applications that leverage the data to support areas such as revenue protection, distribution planning, load research, forecasting, settlement, complex billing and customer service. It's Meter Vision® MDM data repository is currently being used to manage the largest AMI system in North America in terms of data volume, the 1.4M meter system deployed by PPL in Pennsylvania that collects hourly data.

David Bonnett added: "Nexus is probably the leading provider of on-demand applications to the utility industry today and already provides our ENERGYprism® customer self-service and call center applications on a hosted basis to more than 60 utilities across North America, so this hosted MDM offering is a natural extension for us. We have already had significant interest in this service from smaller utilities, and believe it is ideally suited to support time-based pricing programs where cleansing and storing the interval data and calculating the billing determinants is required to support these more complex rates. In fact, we will be using our hosted MDMS environment to support the Ameren real-time pricing pilot in Illinois, where we will be providing customers with high-price notifications, presentation of their usage, and applications to help them decide how to best respond to these price signals."

Nexus indicated that, working with its sister AMI companies DCSI and Hexagram, it will provide pre-integrated end-to-end solutions including hosted services for managing the AMI network operating system. This move positions Nexus, DCSI, and Hexagram as leaders providing full Business Process Outsourcing (BPO) solutions for both MDMS and AMI.
