The issue was that the CSV file was indeed too large. To decrease the size of enduse_timeseries.csv so that it shows up in localResults, you can either

1. reduce the timesteps per hour of the simulation (if you are reporting under the timestep frequency) to reduce the row length of the CSV file.

This was done in measures Timeseries CSV Export and Set Residential Simulation Controls.

or 2. turn off end_use subcategory reporting and include zero additional EnergyPlus output variables to reduce the number of columns of the CSV file.

This was done in measures Simulation Output Report and Timeseries CSV Export.
