     This will require full charging every day when using multi-day

     Add pumped storage option to switch_model.generators.extensions.hydro_system
-
+    
     When using the `hydro_system` module, hydro generators can now be designated as
     reversible (able to do pumped hydro storage) by setting `gen_storage_efficiency`
     in `gen_info.csv` to a numeric value (generally 0.5 - 1.0). To use this feature
     you must also add `switch_model.generators.extensions.storage` somewhere above
     `switch_model.generators.extensions.hydro_system` in `modules.txt`.
-
+    
     When generators are identified as reversible, water can be pumped from the node
     below the generator to the one above, with the specified round-trip efficiency.
     The nodes above and below the generator should have reservoir data in
     reservoirs.csv to indicate the amount of storage available.
-
+    
     The storage module now defines a new set called ALL_STORAGE_GENS, which will
     rarely be used. This is the union of pumped-storage hydro generators and
     standard storage generators (usually batteries), which are still listed in

     Track hydro reservoir levels by timeseries instead of period
-
+    
     The hydro_system module now tracks reservoir levels over the course of each
     timeseries instead of each period. Previously the hydro_system module tracked
     levels of reservoirs across all the timepoints in a period, as if each
     timeseries was linked to the one after it. This was an error, and in models
     with multiple timeseries with different weights, Switch could retain water
     during low-weight timeseries, then release it during high-weight timeseries,
     effectively producing free energy.
-
+    
     The new approach matches the general principle in Switch that each timeseries is
     independent and it must be possible to to repeat each timeseries many times in a
     row if necessary. Although this is more correct than the previous approach, it
     is also more conservative: hydro networks must reach the same level (or a
     prespecified level) at the start and end of each timeseries, instead of the
     start and end of each period.
-
+    
     Users should now set res_initial_vol and res_final_vol for each timeseries in
     reservoir_ts_data.csv instead of setting initial_res_vol and final_res_vol for
     each period in reservoirs.csv. The standard upgrade script will automatically
     make this change if needed. It will also interpolate between the previous
     full-period reservoir volumes to set the reservoir volumes at the start and end
     of each timeseries.
-
+    
     For models with a single, long timeseries for each period (the most common use
     case for this module), this change won't make a difference. However, for models
     with multiple timeseries in each period with different weights, this update
     may change the model results.
-
+    
     In addition, res_initial_vol and res_final_vol are now optional. If
     res_initial_vol is set but not res_final_vol, Switch will set the final level
     equal to the initial level. If neither is set, Switch will choose an optimal
