The Stuxnet worm targeting control systems and utility companies is heavy-duty malware. Security blogger Andy Bochman says that means USG and FERC must get way more serious about energy control system security and issue mandatory policy. Why? Without a crippling blow from Stuxnet, Andy predicts most utilities will simply move along with no procedural changes. Find out why he calls that unacceptable. |

It may not be pretty to look at, but Intergraph and Siemens have taken a step towards seamless outage management in an “off-the-shelf” application. Jesse Berst thinks it's impressive. But is it the holy grail of integrated, real-time outage management? Click inside and see what you think. |

What does the big Y2K scare at the turn of the century have in common with today’s Smart Grid roll-outs? Security expert Andy Bochman recalls that perceived Y2K threats and remediation costs were used to justify new apps and the shuttering of older apps and systems. It became a catalyst for modernization and efficiency – and Andy believes that same ‘taking stock’ drill could be a boon to utilities readying for the Smart Grid. |

Entergy, a Fortune 500 company with 14,300 employees, produces and delivers electric power to 2.7 million customers in Arkansas, Louisiana, Mississippi, and Texas. The company has captured trillions of records from its supervisory control and data acquisition (SCADA) system and its more than 320,000 SCADA objects. To better extract value from SCADA data, the utility deployed a real-time data storage application, called Pegasus RDS, which was created by Microsoft partner Nobadeer Software. |

This white paper discusses how the electric utility landscape has changed over the past few decades, necessitating the smart grid. It then shows how Ethernet-based Supervisory Control and Data Acquisition (SCADA) systems can be used to monitor and control power flowing into and out of the grid and how Ethernet-based SCADA systems can be used to match power inflows and outflows to keep the grid stable. |

The fusion of technologies that is the Smart Grid also represents a mixture of technical cultures. As Pike Research senior analyst Bob Gohn explains, it puts the netheads and the power guys in a culture clash that could influence the Smart Grid’s evolution. His message to industry decision makers? Be aware. |

As this overview discusses, primary drivers for selecting OSIsoft PI at CPS Energy were the ability to create custom displays easier, to retrieve data quickly and easily using common tools such as Excel, plus dissatisfaction with performance of existing historian and a desire to make use of the multiple interface capability (T&D EMS, Gas SCADA, Modbus, etc.) and to provide access to data for staff in corporate offices.

The paper discusses many of the building blocks that need to be considered in developing a plan for the future as well as examples of different approaches taken by utilities for their communications infrastructure for AMI, DA, SCADA and mobile applications such as: WiMAX, Cellular 3G, IP/MPLS, software-defined radio (SDR), and many new microwave products. Many of these recent breakthrough “game changing” communication technologies have been successfully deployed at utilities. |

When does an embarrassment of riches turn into just an embarrassment? When utilities have a wealth of data and don’t take advantage of it. That’s the situation facing most utilities as the Smart Grid goes mainstream. In this preview of John McDonald’s GridWeek panel discussion, he explains how utilities can make powerful use of information they may not even know they have. |

During a CHHP decemtralization project at Alaska's Elmendorf Air Force Base, Ameresco modified substations to accept new capacities for electric service and integrated the base SCADA system into the local utility’s SCADA system for monitoring and control. Additionally, Ameresco upgraded two substations so Elmendorf could receive full electrical service from the local electric utility. |

Unlicensed wireless spectrum may be the Achilles heel for your communications pathway. 700 MHz spectrum can protect your traffic better than any technology. You may need to consider whether licensed spectrum from Arcadian Networks is a faster, safer way to route your voice & data traffic. |

In the 1990s, the city of Auburn, Indiana began work on a fiber-optic network to connect the nine substations in the Auburn Electric Department. The network needed to transport voice and Ethernet services as well as the supervisory control and data acquisition (SCADA) system that is the electric utility’s nerve center. The SCADA system handles telemetry and control functions for the city’s electric grid: opening and closing circuit breakers, monitoring electrical equipment, and protecting relays. To support these critical functions, the network needed to be exceptionally reliable and resilient. |

SGN Contributor, Rik Drummond points out that the benefits Web services (WS) offer the Smart Grid in terms of significant savings are lost because software vendors do not provide off-the-shelf interoperable software while competing standards do. This is an example of how the Smart Grid can be stalled if utilities do not insist that software vendors provide interoperability. |

This paper presents an analysis of SCADA system reliability in terms of its expected. aggregate contribution to load curtailment on the power system. Expressing this aggregate in system minutes and applying an appropriate damage cost function then provides an annual cost measure of SCADA system reliability
