  This report presents our SmartSpace event handling framework for managing
smart-grids and renewable energy installations. SmartSpace provides decision
support for human stakeholders. Based on different datasources that feed into
our framework, a variety of analysis and decision steps are supported. These
decision steps are ultimately used to provide adequate information to human
stakeholders. The paper discusses potential data sources for decisions around
smart energy systems and introduces a spatio-temporal modeling technique for
the involved data. Operations to reason about the formalized data are provided.
Our spatio-temporal models help to provide a semantic context for the data.
Customized rules allow the specification of conditions under which information
is provided to stakeholders. We exemplify our ideas and present our
demonstrators including visualization capabilities.
