# Using URBANopt Results With OpenDSS

A guide to using URBANopt simulation results to understand the interaction of buildings with the electrical grid with OpenDSS.

OpenDSS is specifically designed to help size electrical grid infrastructure correctly by evaluating the performance of transformers and power lines.
