+# Mirror: Wind and Solar Candidate Project Areas, v2
+
+A mirror of the polygon-containing file from Princeton University's **Wind and Solar Candidate Project Areas for Princeton Net Zero America Study (v2)** dataset.
+
+## Contents
+
+- `FinalCandidateProjectAreas-fgdb.zip` — Esri File Geodatabase archive containing five polygon layers:
+  - `SolarCandidateProjectAreaBase`
+  - `SolarCandidateProjectAreaConstrained`
+  - `WindCandidateProjectAreaBase`
+  - `WindCandidateProjectAreaConstrained`
+  - `OffshoreWindCandidateProjectAreaBase`
+
+The layers contain candidate project-area geometries and modeled attributes including area, nameplate capacity (`incap`), annual generation (`egen`), capacity factor (`m_cf`), and simplified LCOE (`LCOE_simp`). The original data use NAD 1983 Albers projection.
