Smart Metering for Water Utilities

Should water utilities replace current consumption meters with “smart metering” systems that provide more information to both utilities and customers? This question is being hotly debated in today’s electric utility industry but currently appears to be of less interest in the water industry.

Gustav Causes Second-Largest No. of Outages in Entergy History

Hurricane Gustav made landfall Sept. 1, at 10 a.m., near Cocodrie, Louisiana. At the peak, 850,000 Entergy customers, primarily in Louisiana and Mississippi, had lost electrical service due to the storm. Hurricane Gustav caused the second largest number of outages in company history, behind only Hurricane Katrina. Gustav restoration rivals the scale and difficulty of Hurricane Katrina restoration.

  • As of 11 a.m. today (Sept. 2), more than 826,000 customers were still without power throughout the Entergy service territory.
  • Nearly 24,000 Entergy customers have been restored whose electrical service was disrupted by Hurricane Gustav.
  • Bad weather from the storm continues in the Entergy system, impeding progress to restore service and assess damage. Early assessments indicate extensive damage to Entergy’s system in Louisiana.
  • Entergy’s team of more than 10,000 restoration workers has begun safely restoring service as quickly as possible.
  • Some workers continue traveling toward Entergy’s territory. Workers are responding from Connecticut, Delaware, District of Columbia, Florida, Georgia, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Missouri, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Utah, Virginia and Wisconsin.
  • Entergy’s transmission system has sustained massive damage, with 191 transmission lines and 210 substations out of service.
  • The New Orleans area to near Baton Rouge remains essentially an island, no longer electrically connected to the rest of the system. Waterford 1, Nine Mile Point and Little Gypsy are now supplying all power to this area because all transmission lines leading to and from the area are out of service.
  • Entergy restoration organizers are assessing how to best to tie and synchronize this area back into the Entergy system. This will be a very delicate operation requiring close coordination between generation, transmission, distribution and other Entergy functions.
  • Entergy’s Waterford 3 Nuclear Plant near New Orleans completed a controlled shutdown on Sunday night in accordance with procedure at approximately 10:30 p.m. in anticipation of the heavy winds that were forecast for Monday morning.
  • River Bend Nuclear Station was brought offline on Monday evening due to loss of demand caused by extensive outages in the region.
  • Personnel at both plants are performing site assessments this morning and working closely with the Nuclear Regulatory Commission and Federal Emergency Management Agency to determine a timeline for restart.
  • Bringing the plants online will be closely coordinated with utility company personnel to maintain the reliability of the power grid.
  • The number of outages already known to have been caused by Gustav is the second highest in Entergy’s 95-year history. The only larger number was 1.1 million during Hurricane Katrina, which has been described as one of the worst natural disasters in American history.
  • With many people evacuated from coastal Louisiana and thus unavailable to report outages, the total number is expected to grow. As customers return to their homes, Entergy requests that they report their outages. The fastest way is to dial 800-9OUTAGE and use the automated system.
  • The time required to restore service is unknown at this time. Determining the time required is dependent on when the company can assess damage to its facilities.
  • Entergy preparations began early last week, well in advance of Hurricane Gustav. Entergy is nationally recognized as a leader in the industry at restoring major damage safely and quickly.
