The advent of smart grid technology has raised new and challenging issues concerning data privacy. Of course, data privacy isn’t a new concern for the energy industry, as utilities have always collected customer data, some of which is common to any business, such as contact and credit information, and some of which is unique to the energy industry, such as usage and demand data.

(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.

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.

Four years ago, Congress made its wishes known: it tabbed the National Institute of Standards and Technology to develop a set of standards for the smart grid, and then instructed FERC, the Federal Energy Regulatory Commission “adopt” those standards, but only after finding a ”sufficient consensus,” and only “as may be necessary” to assure “functionality and interoperability.” Yet what is known is not necessarily clear. Who decides if consensus prevails? What does “interoperability” mean? Should FERC’s “necessary” finding extend to retail smart grid applications, arguably outside its purview? And the biggest dispute — must standards be mandatory? — finds PJM at odds with much of the utility industry.

The goal of implementing a distribution management system (DMS) is to upgrade isolated, hands-on grid management processes into an interconnected and automated platform. This technology is transforming the way utilities operate distribution networks, and setting the industry on a path toward seamless integration of distributed resources—both supply and demand.

Smart metering and beyond-the-meter technologies are challenging the utility monopoly model. Now, regulated utilities must re-think their customer relationships as a revitalized retail sector provides growth opportunities.

Investor-owned utility executives have long understood the benefits of prepaid metering, but technical and regulatory roadblocks have prevented wide-scale implementation. Now, however, two IOUs—Arizona Public Service and DTE—are planning prepaid metering programs that could be offered to all customers. Smart metering technology might pave the way for prepaid to become a standard service.

T&D and Smart Grid

The ZigBee Alliance and the Wi-Fi Alliance entered an agreement to collaborate on wireless home area networks (HAN) for smart-grid applications. The initial focus of the collaboration will be ZigBeeSmart Energy Profile 2.0, which is the next-generation energy management protocol for smart grid-enabled homes based on today’s successful ZigBeeSmart Energy Profile. The ZigBeeSmart Energy Profile 2.0 is expected to be extended to operate over Wi-Fi technology as a result of the collaboration.
