Proposed NEMA ASHRAE facility smart grid model standard open for public review

July 27, 2012 | By Anthony Capkun

July 27, 2012 – The National Electrical Manufacturers Association (NEMA) and ASHRAE are jointly developing Standard 201P, “Facility Smart Grid Information Model”, which would provide a common basis for electrical energy consumers to describe, manage and communicate electrical energy consumptions and forecasts. The proposed standard is open for an advisory public review until September 3, 2012.

“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 generations and distribution. The vision of the smart grid changes this picture radically.”

In a smart grid world, says Bushby, facilities become partners in supporting and managing the electric grid. “Facilities become generators using local renewable or other generation capacity. Facilities moderate electrical demand in response to fluctuations in the price or availability of electricity. Facilities communicate and negotiate with energy providers, sharing information about the facility’s projected electrical demand or ability to respond to the energy provider’s needs for maintaining grid stability and reliability”.

Proposed 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,” Bushby said. “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 standard is part of ASHRAE’s supporting efforts for the Smart Grid Interoperability Panel, a public-private partnership initiated by the National Institute of Standards and Technology to speed development of interoperability and cyber security standards for a nationwide smart electric power grid.
