Proposed facility smart grid model standard open for review

Atlanta, GA, U.S.A. — (METERING.COM) — August 15, 2012 – A proposed standard to create smart facilities supporting a national smart grid effort is open for public comment.

Standard 201P, Facility Smart Grid Information Model, which is being developed jointly by ASHRAE and the National Electrical Manufacturers Association (NEMA), is aimed to provide a common basis for electrical energy consumers to describe, manage and communicate about electrical energy consumptions and forecasts.

“Historically, electricity consumption has been viewed as a collection of dumb loads at the end of a distribution system,” said Steve Bushby, chair of the committee writing the standard. “There has been almost no interaction between the ‘loads’ and those responsible for electricity generation and distribution. The vision of the smart grid changes this picture radically. In a smart grid world, facilities become full partners in supporting and managing the electric grid.”

The proposed standard 201P would define an object-oriented information model to enable appliances and control systems in homes, buildings and industrial facilities to manage electrical loads and generation sources in response to communication with the smart electrical grid and to communicate information about those electrical loads to utility and other electrical service providers.

Energy providers would benefit because it enables interaction with all different types of facilities in a common way. Facility owners benefit because products can be designed for use in multiple facility types, and products designed primarily for one type of facility, a home for example, can more easily be used in another, say a commercial buildings.

The proposed ASHRAE/NEMA standard will coordinate with work by the North American Energy Standards Board to develop a basic energy usage data model standard and create a facilities data model that provides additional energy usage data elements for commercial and industrial buildings. This includes lighting, heating, HVAC&R and other electrical loads.
