Assessment of Rooftop Area in Austin Energys Service Territory Suitable for PV Development

As part of the Solar America Cities program, Austin Energy proposed to perform an assessment of the rooftop area available for PV development within its service area. Austin Energy contracted with Clean Energy Associates (CEA) to perform the analysis. This report summarizes the project objectives, data sources and methodological approach employed, and results.

Key questions addressed by this project were:

  1. What is the aggregate rooftop area, rooftop area suitable for PV project development, and potential for PV capacity and energy production from rooftop solar photovoltaic systems on key building types in Austin Energy’s service area?
  2. How do the potential capacity and annual energy production from rooftop solar electric systems compare with Austin Energy’s current capacity and annual energy requirements?
