What is a Moveable Load?
A Moveable Load is a flexible energy delivery setup that lets you define how much energy (kWh) needs to be delivered within a time window you choose.
Within that window, the system automatically optimizes when and how much power (kW) to deliver, looking for the most efficient and cost-effective profile.
Typical use cases include:
Nighttime charging for EV trucks
Scheduling heat pumps during off-peak hours
Any asset that needs a fixed amount of kWh within a certain time range, but doesn’t care exactly when within that range it runs
This helps you:
Reduce energy costs (e.g. by avoiding peak tariffs)
Reduce strain on the grid
Ensure the required energy is still delivered in time
How the Moveable Load works
You define:
On which day(s) it should run
A start time and duration (the time window)
The maximum kW allowed
The requested kWh to be delivered
Within that window, the system:
Adjusts the actual power usage over time (up and down)
Stays within the Max kW
Aims to deliver the Requested kWh in the most optimal way
After the session, you can check the report to see:
How much energy was actually delivered
Whether the full requested amount was reached
When and how much power was used throughout the window
Parameters of a Moveable Load
To set up a Moveable Load correctly, you need to configure the following parameters.
Day of the Week
Select the days on which the Moveable Load should be active.
Use this to control which nights or which weekdays the schedule applies to.
When scheduling nighttime sessions that cross midnight, make sure you select the day based on when the session starts.
Example: If a session runs from 22:00 to 04:00, starting on Monday at 22:00 and ending on Tuesday at 04:00, you should select Monday.
Start Time
Set the Start Time as the moment your delivery window begins.
This does not mean consumption starts exactly at this time.
It means: from this time onward, the system is allowed to start delivering energy until the end of the duration.
Example: Start Time = 22:00 → the system may deliver energy any time from 22:00 until the end of the duration window.
Duration
The Duration defines how long the system has to deliver the requested kWh.
Expressed in hours and minutes
Starts counting from the Start Time
Determines how much the system can spread out the energy delivery
Example:
Start Time = 22:00, Duration = 6 hours → delivery window is from 22:00 to 04:00.
A longer duration gives the system more flexibility to:
Avoid peak prices
Shift load to cheaper or less congested hours
Max kW
Max kW is the maximum power that can be used at any moment during the session.
Acts as a cap on the instantaneous power draw
Protects your site or asset from exceeding capacity limits
Directly affects how fast the requested kWh can be delivered
Example:
If Max kW = 50 kW and Duration = 4 hours, the theoretical maximum energy you can get is 50 kW × 4 h = 200 kWh.
Requested kWh
Requested kWh is the total amount of energy you want to have delivered within the given duration.
The system will try to reach this amount by adjusting the kW usage over time.
It must remain within:
The Duration
The Max kW limit
Tip: If your Requested kWh is higher than what is possible with your Max kW and Duration, the system will not be able to deliver 100% of it.
Report Explanation
Once a Moveable Load session has run, you can use the report to understand how energy was delivered and how efficiently the configuration performed.
Chart 1: Possible vs Actual Energy Delivered
Chart 1 typically shows:
Possible energy consumption
Calculated as:
Max kW × Duration (in hours)This is the theoretical maximum energy that could have been delivered if you used the full Max kW for the entire duration.
Actual energy delivered
The real kWh that was delivered to the asset during the session.
This is affected by asset behavior, constraints, and optimization choices.
Use this chart to quickly see:
Whether you’re using the full potential of your setup
If there is unused capacity that could be optimized
Chart 2: kW Usage Over Time
Chart 2 displays kW usage at specific times during the selected period.
It shows:
How the power level ramps up or down
When the system chooses to deliver more or less energy
Periods of low or zero usage within the delivery window
This helps you:
Identify power peaks or dips
Spot optimization opportunities (e.g. shifting more load to cheaper hours)
Understand how the system responded to constraints and pricing
Key Metrics in the Report
kWh Requested
The total energy amount you asked the system to deliver in the session.
This is the same as the Requested kWh parameter you configured.
kWh Used
The actual energy consumed by the asset during the session.
This is what really happened in terms of kWh delivered.
kWh Possible
The maximum potential energy that could have been delivered, given the constraints:
Max kW
Duration
Calculated similarly to: Max kW × Duration (hours) (adjusted for any additional system constraints).
Use this to understand whether your request was realistic:
If Requested kWh > kWh Possible, you will never reach 100% delivery.
Percentage of Requested kWh Provided
The ratio of kWh Used to kWh Requested:
Shows how well the system fulfilled your request.
A value close to 100% means the system could deliver nearly everything you asked for within the given constraints.
If this percentage is consistently low, consider:
Increasing Duration
Increasing Max kW (if physically possible)
Lowering Requested kWh to a realistic level
This structure should help you both set up Moveable Loads correctly and interpret the resulting reports so you can fine-tune performance over time.
