    The need for security in smart metering is well understood. But ensuring security end-to-end means addressing potential issues at each stage of the meter's lifecycle, writes Elster's Michael John, solutions manager.

    This is an article speculating upon advanced cars of the future, looking at the near-future (5 years), mid-future (10 years), and longer-future (15-20 years) future. I say "advanced" cars because of course not all features appear everywhere instantly: typically, there are some vehicles that are early adopters of new technology, and conventional vehicles may continue to be made well after the advent of new technology (consider a comparison of the technologies in my four-wheel vehicles: a Toyota RAV4 EV and a Dodge Caravan).

    Utilities are producing big volume of data that is coming from smart meters, smart sensors and other new devices. With the significant increase in amount of incoming data utilities may face challenges if this data is not managed effectively. The exponential growth in meter data will impact system performance as extracting information will be sluggish and utilities will not be able to analyze information quickly which is required for effective decision making. Moreover Managing and extracting business value out of the huge data without use of big data analytics tool can devastate current IT resources.

    As utilities face increasingly challenging market conditions, electric vehicles (EVs) may present utilities with some interesting opportunities. Challenges ahead for utilities are expected to strain their financial health, which will likely result in retail rate increases. And that's where EVs might offer revenue growth that could help offset revenue loss from current energy efficiency trends and rising costs from expansive infrastructure replacement and upgrade investments.

    Grid-scale energy storage technologies are set to play a crucial role in the today's evolving power system. System operators and utilities are continuously working to improve grid efficiency and reliability and look to storage technologies to do so. Storage can lend a helping hand in implementing numerous applications, including renewable integration, power flow optimization, frequency regulation, and congestion management. However, it is important to utilize technologies that can accomplish this in the most economic and efficient way. Let's take a look at the different storage methods that are in use today.

    One of the biggest concerns with many forms of renewable energy is their inability to store active energy during times when the sun isn't out, or when the wind isn't blowing. With these energies gaining popularity and growing at an impressive rate, it seems as though establishing an efficient form of energy storage is a foregone conclusion for the future.

    So you have decided to enroll your facility in a demand response program. You understand that your organization will be protecting the electric grid from blackouts and brownouts during times of high demand, and you are aware of the revenue your organization will earn from this program. The only thing left to do is to work with your demand response provider and develop a successful reduction strategy to implement during an emergency event. Although each organization is different and will require a tailored plan, there are eight main strategies that prove to be effective for most facilities.

    The generator is the single most capital intensive and significant equipment in the power system and hence its protection becomes very critical both to the faulted generator as well as the power system fed by it. Damage to the generating unit can take away lot of outage time which shall directly impact the revenue of the utility producing power. Hence, generator protection assumes prime importance in the field of protection design.  The case of an earth fault on an ungrounded synchronous generator has been analyzed, some conclusions have been derived which shall impact the setting of the field failure protection and also setting guidelines for field failure protection for different conditions have been derived.

    Electrify Heartland (EH) is a product of the Greater Kansas City Plug-In Readiness Task Force, which is managed by the Metropolitan Energy Center of Kansas City. EH's goal is to produce a regional plan to prepare public resources and secure the economic and environmental benefits of plug-in vehicles within targeted metro areas with an estimated population of 2.7 million people. The plan will be publicly releasable and replicable for electric vehicle (EV) and charging infrastructure deployment in other regions. This planning effort focuses on the deployment of 1 million U.S. EVs by 2015.

    The five billion euro question should be...where's ROI? The European Court of Auditors was not looking for Elmo recently they were looking for return on investment for the five billion Euros (6.7 billion US dollars) spent through the European Union's Cohesion Policy Fund.
