NEMA announces completion of advanced electric metering standard

Standard forges first link in smart grid standard chain, defining smart meter upgradeability, NEMA says.




In conjunction with an address on Sept. 24 by U.S. Commerce Secretary Gary Locke to a GridWeek audience , the National Electrical Manufacturers Association (NEMA) has announced the completion of SG-AMI 1-2009 Requirements for Smart Meter Upgradeability, which the group characterizes as the first official original smart grid standard.

SG-AMI 1-2009 was developed by a team of meter manufacturers and electric utilities to provide guidance to utilities, state commissions, and others that want to deploy advanced metering infrastructure (AMI) prior to completion of the standards work identified in the National Institute of Standards and Technology (NIST) Smart Grid Interoperability Roadmap.

Gaddis. "Second, the standard was completed in less than 90 days from the creation of the standards task team to the official approval by an authorized standards development organization."

NIST conducted several workshops throughout 2009 to obtain input on the development of a Smart Grid Interoperability Roadmap. The roadmap identifies a plan for moving forward with the development and/or modification of smart grid related standards. While the roadmap and its component priority action plans will take several years to complete, utilities and other stakeholders need guidance on the purchase of smart grid products and systems today. In particular, utilities are installing AMI and smart metering systems now to bring smart grid benefits to consumers as soon as possible.

To provide this guidance, Dr. George Arnold, NIST national coordinator for smart grid interoperability, called on NEMA to conduct an accelerated standards development effort. The objective was to define requirements for smart meter firmware upgradeability in the context of an AMI system using a common vocabulary among industry stakeholders, such as regulators, utilities, and vendors.

"NEMA accepted the challenge to lead this effort to develop a standard set of requirements for smart meter upgradeability on an exceptionally rapid schedule," said Gaddis.

The standards team included meter manufacturers Elster Electricity, GE, Itron, Landis+Gyr, and Sensus; electric utilities Alabama Power, Consumers Energy, Georgia Power, Oncor Electric Delivery, and Southern California Edison; as well as representatives from the U.S. Department of Energy Pacific Northwest National Lab, EnerNex, and NIST.

According to John Caskey, NEMA industry director, "it was exciting to facilitate a team of extremely knowledgeable and energized professionals to complete this task on such a rapid schedule."

The team completed the draft of the standard in less than 60 days, and coordinated the review and approval within NEMA in roughly 30 days. In total, the entire project, from initial team meeting to officially approved standard, was completed in less than 90 days. This standard will be used by smart meter suppliers, utility customers, and key constituents, such as regulators, to guide both development and decision making as related to smart meter upgradeability.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
