 However, in some settings, we can reduce electricity bills by *just* consuming energy smartly. In other words, if the process can be displaced, by breaking it into smaller consumption periods or shifting its start time, the process run can match the lower price hours better.
 
-For example, we could have a load that consumes energy at a constant rate (e.g. 100kW) for a fix duration (e.g. 3h), but there's some flexibility in the start time. In that case, we could find the optimal start time in order to minimize the energy cost.

 Examples of flexible processes are: 
     - Water irrigation in agriculture
     - Mechanical pulping in the paper industry
-    - Water pumping in waster water management
+    - Water pumping in waste water management
     - Cooling for the food industry
 
 
-For consumers under ToU (Time of Use) tariffs, FlexMeasures `ProcessScheduler` can plan the start time of the process to minimizes the overall cost of energy.
-Alternatively, it can create a consumption pan to minimize the CO2 emissions.

-In the first policy, there's no flexibility and it needs to schedule as soon as possible. Meanwhile, in the BREAKABLE policy, the consumption blocks surrounds the time restriction to consume in the cheapest hours. Finally, in the SHIFTABLE the process is shifted to capture the best prices, avoiding the time restrictions.
