VirtuWatt Link is a Web-service application that facilitates automated-load-response-program participation. It allows a facility’s existing automation system to manage load curtailment automatically based upon energy market signals and pre-set scenarios, without the installation of redundant or proprietary building-control hardware. By reducing the upfront cost associated with load-response automation, VirtuWatt Link is designed to enable a broader range of facility types and sizes to participate in a wider array of energy market programs. VirtuWatt Link provides comprehensive load-response and security services, including authentication access control, ISO event dispatch notification, and acknowledgement and utility meter usage data. It can be integrated to any energy-management or controls system that utilizes Web services. Its architecture is designed to seamlessly handle demand-response market signals and energy data from utilities and independent system operators, and is built to accommodate developing demand response protocol standards, such as OpenADR 2.0. It is an extension of Constellation’s VirtuWatt™ energy-management platform, which allows commercial and industrial customers to easily monitor energy usage in real time and schedule load curtailments for load response programs. —Constellation
