Question

Draw BPMN diagram model  on the business process for retailers to sell electricity to consumers in the Open Electricity Market.

Answer 1

Business Process Model and Notation (BPMN) provides a graphical representation of business workflows that anyone, from business analyst to stakeholder, can easily understand; aiding in business process analysis and business process improvements

A business process model and notation diagram, or BPMN diagram, is used to build easy-to-read business process model flowcharts, which can be shared across organizations and industries. BPMN diagram symbols are categorized into four main groups: flow objects, connecting objects, swimlanes, and artifacts.

1. Select Diagram > New from the main menu.
2. In the New Diagram window, select Business Process Diagram and click Next.
   
3. Select an existing BPMN diagram template, or select Blank to create from scratch. Click Next.
4. Enter the diagram name and click OK.
5. Drag and drop shapes from the diagram toolbar.
   
6. Use the Resource Catalog to complete the diagram. Move your mouse pointer over a shape. Press on the resource icon and drag it out, and then select the shape to create. A connector will be automatically created for you.
7. When you finished, you can export the diagram as an image (JPG, PNG, PDF, SVG, etc) and share it with your friends or co-workers (Project > Export > Active Diagram as Image…).

The electricity market consists of the wholesale electricity market and the retail electricity market:

The Wholesale Electricity Market:

Power generation companies have to bid to sell electricity in the wholesale electricity market every half-hour. Depending on electricity demand and supply, the price of electricity in the wholesale electricity market changes every half-hour.

Electricity retailers buy electricity in bulk from the wholesale electricity market and compete to sell electricity to consumers.

Power generation companies have to bid to sell electricity in the wholesale electricity market every half-hour. Depending on electricity demand and supply, the price of electricity in the wholesale electricity market changes every half-hour.

The Retail Electricity Market:  The Energy Market Authority (EMA) has progressively opened up the retail electricity market to competition. This is to allow consumers to enjoy more choices and flexibility when buying electricity.
