What are Grouped Projects?
VCS allows for Grouped Projects, which are similar to the CDM's Program of Activities. Grouped projects bring together several instances of the same activity into one Project Description, and allow new instances to be introduced as the project proceeds. This allows projects to start before every instance is identified and to bring more instances into the project as they are added. For example, a project installing solar PV systems in homes does not need to identify and include all homes in the Project Description before starting the project. Rather, new households can be added as the project proceeds. Project monitoring is done through one central information system, and the Project Crediting Period starts on the date the first (installed) system begins reducing GHG emissions. Systems installed later only earn credits for the remainder of the Project Crediting Period.
