(November 2011) Hitachi Power Systems America wins contract from Westar Energy; City of Fort Collins selects Elster, Siemens Energy, eMeter and Tropos GridCom to provide systems for its AMI project; Energate to supply smart thermostats for Oklahoma Gas & Electric; Jackson Municipal Electric Department selects Survalent Technology for a new SCADA system; Eastern Nebraska Public Power District Consortium selects ABB to implement an advanced smart grid-based SCADA; plus announcements and contracts involving EnerSys, S&C Electric, Siemens and others.

NERC’s critical infrastructure protection (CIP) standards set a minimum level of security performance—and only for high-voltage transmission systems, not the distribution grid. A compliance-checklist approach to security might lack the adaptability needed to combat evolving threats like the Stuxnet worm. A multi-layered, risk-based approach will provide better protection for the emerging smart grid.

New technologies—and new expectations—require taking a fresh look at the institutions and practices that have provided reliable electricity for the past century. Collective action is needed to define the key attributes of a future grid and then to take the more difficult next step—adapting our processes and institutions to align with that future vision. A thoughtful approach will allow America to capture the potential value that’s offered by sweeping changes in technologies and policies.

Smart grid technologies bring a host of cyber security considerations that need to be addressed throughout the T&D domain—and even into the customer’s home. In this exclusive report, Department of Energy authors team up with industry experts to examine how to deal with the changes and challenges of securing the smart grid.

Regulators across the country are relying on conservation-potential assessments to guide their policy decisions. Models based on macroeconomic analysis, end-use forecasting and accounting measurements provide different ways to assess the achievability of conservation and efficiency goals.

Advanced distribution management systems (DMS) are providing unprecedented levels of control and efficiency. With greater knowledge about system loading and status, utilities can better make investment decisions—and operators will be better able to keep the lights on as the power system evolves.

Customer value is a key factor in any smart grid business case. But not all customers are created equal. In particular, commercial and industrial (C&I) customers have greatly different needs, considerations and sensitivities, compared to residential customers. As a result, demand response and efficiency programs won’t produce the same results across customer classes. Getting the most from the C&I market will depend on integrating smart grid with smart building technologies.

Advancements in forecasting have improved the reliability of day-ahead and hour-ahead estimates of wind generation. Wind never will behave like a base-load power plant. But as system operators integrate wind forecasts into their planning and market processes, they’re transforming intermittent wind energy into a variable but reliable resource.
