Annex A is about Metrics for the Smart Grid System Report. This annex presents papers covering each of the 20 metrics which were prepared in advance of the main body of the report and collectively form its informational backbone. The list of metrics is derived from the material developed at the Smart Grid Implementation Workshop. The objective of the metric development process was to distill the best ideas into a small number of metrics with a reasonable chance of measurement and assessment.
Annex B is about Electricity Service Provider Interviews. To assess the state of smart-grid deployment, metrics were established to measure these attributes. Data collection for the Smart Grid System Report was performed by interviewing 21 selected electricity-service provider organizations representing a cross section of the industry. As part of the agreement with interviewees, the results were provided to all participants in a blinded form in advance of the report to Congress.
