Raleigh, NC, U.S.A. --- (METERING.COM) --- October 22, 2010 - The UCA International Users Group (UCAIug) has released the first version of the Open Automated Demand Response (OpenADR) System Requirement Specification (SRS).

OpenADR is an open and interoperable information exchange model that facilitates the automation of demand response (DR) in commercial and industrial facilities. OpenADR is commercially implemented to automate DR programs and has been adopted by a wide range of building and industrial controls companies for various grid supply and demand side management activities.

As of 2010, over sixty control vendors have implemented the OpenADR client. Further, OpenADR has been selected as one of the key smart grid standards by the Smart Grid Interoperability Program (SGIP) at the National Institute of Standards and Technology (NIST).

Over 20 individuals representing over 10 companies and organizations collaborated over the past six months to complete this effort. The original OpenADR specification released by Lawrence Berkeley National Lab (LBNL) was utilized as a base foundation for the OpenADR document.

The OpenADR specification has been approved by the OpenSmart Grid Users Group (OpenSGug) Technical Subcommittee, which is one of the three user communities supported by the UCAIug, and is now available for public use.

The OpenADR SRS utilized the Common Information Model (CIM) standard to provide both the functional and technical guidance and requirements needed to serve as the “rules of engagement” for DR messaging and data exchange in order to achieve interoperability of DR systems. This would lead to open and interoperable components that can be delivered with different smart grid vendor products and/or solutions within the scope of OpenADR. The functional requirements will be driven by business processes and the technical requirements will be driven by architectural principles and best practices.

The SRS focuses on the requirements to support the interactions and exchange of information for the purposes of DR and includes the exchanges of DR related information between various entities dealing with the utilities, such as Independent System Operators (ISOs), aggregators, energy service providers and end use customers.

The scope of OpenADR SRS includes standardizing dispatch, control and pricing signals for DR and distributed energy resources (DER).

“This document will be a useful tool for energy service providers, ISO/RTO, aggregators and control vendors who are looking to offer demand response solutions to their clients and customers,” commented Albert Chiu of OpenADR Task Force, who led the OpenADR SRS 1.0 effort.
