New OpenADR Spec Will Boost Auto-Demand ResponseThe long-awaited OpenADR 2.0a profile specification was launched on August 8. Expected to have a positive impact on the demand response (DR) market, especially automated DR (ADR), the new spec will spur the development and deployment of new OpenADR-certified smart grid technologies that utilities and grid operators across the world can use to facilitate and augment DR programs. In particular, devices based on this new specification will operate on a lower-cost, faster, and more reliable and efficient communications system. Using a common language (XML) and existing Internet technology, DR signals can be sent directly from a demand response automated server (DRAS) via a client to the building automation and control systems on customer sites. Thanks to this two-way messaging capability between a DRAS, which publishes information, and a client that subscribes to the information, utilities, grid operators, and curtailment service providers (CSPs) will be able to manage peak demand and load shifting in an automated fashion. |
