You can create a default system plan supply capacity table and individual supply capacity tables for each plan.

> ℹ️ **Note**
> ℹ️ 
> ℹ️ If you create a supply capacity table for a plan, that table will become the default supply capacity table for that planning area. Otherwise the system supply capacity table will be the default.

To configure a supply capacity table:

**Step 1**

Create a default system plan supply capacity table in the  System Plan Supply Capacity Module or create supply capacity tables for individual plans in the Plan History module or the Rationing module on the Supply Capacity Parameters tab.

**Step 2**

To create a new table entry, click the **Insert** button and enter the following details:

| Field | Description |
| --- | --- |
| Hour | Number of hours since the start of the plan day. For example, if the plan day starts at midnight, the flow value at '10' refers to the flow at 10 am<br>This must be an integer and may be positive or negative. |
| Flow | Supply flow at that time. This must be an integer. |

**Step 3**

Click **Save** to save your changes.

> ℹ️ **Note**
> ℹ️ 
> ℹ️ The supply capacity for a plan should be the expected flow at the regulator that is designated as the top regulator for the planning area. (This is configured using the TOP REGULATOR relation on the Relations tab of the planning area).
