Hybrid AMR System
Datamatic Ltd. announces MOSAIC, a new hybrid automated meter reading (AMR) system capable of reading water, gas and electric meters via handheld, mobile and full-mesh network-collection platforms from the same endpoint.
When the utility is ready for full-network operations, MOSAIC gateways are installed and connected to a CDMA, GPRS, WiFi, POTS or Ethernet data backhaul.
When MOSAIC is operating as a mesh network, it is self-configuring and self-healing. MOSAIC is designed to reroute around issues, compensate and deliver the utility's data, all without user intervention.
FIREFLYs are powered by processors equivalent to those found in a typical PDA. They support sophisticated, user-defined algorithms that can monitor for conservation violations, perform detailed load studies, alert to usage on an inactive account, spot irregular usage and detect leaks.
FIREFLYs also automatically send packets of usage data over the network when problems are detected. So, not only are personnel alerted to issues, but they are given detailed interval data “bracketing” the problem. This allows utilities to focus their analysis on known issues, rather than combing through mountains of data just trying to locate problems. FIREFLYs are compatible with virtually any meter, eliminating the need for costly meter/register changeout as part of AMR projects.

Performance-Based Rates Study
The Newton-Evans Research Co. has released highlights of findings from its study of performance-based rates (PBR) in the electric power distribution utility business. This report is based on surveys and interviews conducted with public utility commissions (PUCs) in the United States and the District of Columbia, and the regulatory/pricing management at major IOUs. The 27 utilities participating in the new PBR study serve more than 15% of all U.S. electricity consumers. Ten of the responding utilities have some form of PBRs in effect or planned, and six have penalty-based rate structures predicated on customer service levels or the performance of their electric distribution system similarly in place or planned.
The mid-2007 PBR report contains an update from the state public utility commissions on the status of PBRs in their states, as well as information on electric deregulation activity. Interviews were conducted with many of the utilities having some experience with PBR's, as well as leading utilities currently not participating in PBR's, to see if they were considering PBRs in their future plans. Together, the information received from the PUCs and utilities provides a thorough nationwide perspective on the status of power-delivery PBRs now and in the foreseeable future, and may set the stage for further implementation of PBRs. Among the findings from this mid-2007 study of each of the American PUCs and many major utilities are these:
Unlike federal efforts at the generation and transmission levels, deregulation at the distribution and retail levels continues to be a “states' rights” issue as of June 2007. This soon could change if the proposed new “Energy Independence” bill is approved by Congress and signed into law.
Several state commissions continue into mid-2007 with deregulation decisions put on hold due to several factors, including some unremarkable changes that resulted in states that have deregulated. A few states are trying to turn back the clock and assemble the industry as it was in years past.
In some states, it has been the utilities themselves that have requested the commissions to rule on development of PBRs.
