Dispatch Advisories

System Management must inform Market Participants and Network Operators of impending or current situations that could have security ramifications for Market Participants and Network Operators. It does this by issuing dispatch advisories in the following situations.

• Generation shortfall/load shedding occurring or expected.
• Conditions where committed generation running at minimum levels will exceed forecast load (over-generation).
• Any Ancillary service shortfalls.
• Major facility outages (generation, transmission, major loads).
• Fuel shortages that have a wide spread impact on the market.
• Dispatch or communication system outages.
• Notification of starting or ending a high risk or emergency operating state.

A dispatch advisory includes a statement of the operating state (Normal, High-Risk, or Emergency) during the period to which the advisory relates. These advisories include information on how Market Participants should respond to the situation. The Market Rules recognise that sometimes System Management has to react so quickly to a situation that it is not be able to issue a Dispatch Advisory until after the event.
Market Participants are obliged to keep System Management informed of any circumstances that they become aware of that might result in System Management issuing a dispatch advisory.
