    With the recent 60 Minutes TV profile of Daniel Day-Lewis, who so powerfully portrayed our most popular US President in the 2012 bio-pic 'Lincoln', we continue to examine the emotion and pain of the Civil War.  With President Obama's SOTU address, we're reminded that the nation remains essentially at war over the development and delivery of energy.  The battles to decide our most economically and environmentally sustainable path forward are being waged in legislative chambers, courtrooms, town halls and countless media channels and editorial pages.

    Utility companies are under increased pressure to build new infrastructure that will drive better performance and returns for decades. Recent natural disasters have brought this issue to the forefront but it requires capital. According to Booz & Company, "Capital expenditure requirements across the U.S. utility industry are expected to exceed US$100 billion annually through 2020. This represents an increase of 100 percent over the annual costs of the early 2000s, according to Edison Electric Institute."

    Over the last decade and a half, technology and innovations have had great impact on Outage Management Systems (OMS). The latest OMS is much more robust, uses web technologies, integrates with more Information Technology (IT) and Operational Technology (OT) systems, contains more tools, supports special device types, and communicates with Smart Grid enabled networks. While they were never simple systems, the capabilities of OMS continue to grow. Early OMS implementations contained configurations custom to their deployment.

    The St Lawrence River has for decades served the needs of the energy and transportation sectors. Ships have carried towers and turbine blades for the wind energy sector, while a new hydroelectric installation is being completed on the Canadian side of Niagara Falls. The waterway is home to several hydroelectric power installations and it serves as the heat sink for several coal-fired and nuclear-thermal power stations as well as 3-ethanol plants.

    The variable operations of weather-related Distributed Energy Resources in distribution systems cause voltage fluctuations at different buses of the distribution circuits. These fluctuations may significantly impact the power quality as well as the reliability of other volt/var controlling devices. Compensating changes of the DER reactive power may be used to mitigate these voltage fluctuations. This paper discusses two methods of such compensation, compares them in terms of a number of operational criteria, and presents an illustrative numerical example.

    Thermal standards for homes were established to improve thermal performance by strengthening the barrier between outside and the conditioned interior. A checklist of thermal standards is included in the energy code. For example, wall insulation in Oregon has to be rated at least R-21. A building inspector verifies compliance for each component of the thermal shell: foundation, underfloor, walls, roof, skylights, doors and windows.

    Today's power distribution control center manages the day-to-day operation of distribution network to ensure uninterrupted power supplies to the end customers. Today there is limited automation in distribution networks which results in lack the holistic visibility of real-time situation for an operator. With the advent of Smart Grid, there is an increase in development of next generation sensors, controllers and standard based system integration tools.

    AMI (Advanced Metering Infrastructure) programs are typically quite complex and burdensome for the utilities, fraught with risks and challenges during their journeys towards successful implementations. Managing and mitigating the multitude of challenges and risks during an AMI implementation life cycle can drain the utilities of their energy and shift their focus away from their core day to day business activities. In this situation, AMI Managed Services...
