Business Rules for the Planned Outage Co-ordination Process

Business Rule 1

General Principles:

• Asset owners will use reasonable endeavours to provide accurate, up to date information about outages to the System Operator
• Asset owners reserve the right to change any planned outage

Business Rule 2

An outage is defined as: Any asset which is not capable of the generation, conveyance or consumption of electricity.

Business Rule 3

Asset owners will provide the System Operator with information about either:

• All outages; OR
• Specific outages at the discretion of individual Asset Owners

Business Rule 4

Asset owners will provide outage information to the System Operator:

• Up to 12 months out from the planned outage;
• As soon as practical in each instance.

The information will hold good until changed by notification from the Asset Owner.

Business Rule 5

All outage information provided through the POCP will be published.

Business Rule 6

Asset owners will provide the following information:

• The asset owner's unique record ID
• The asset owner
• The asset
• Start date and start time
• Finish date and finish time
• Type
• GIP or GXP
• Change in asset capability, stated in applicable units e.g. megawatts, megavars, amps
• Status of the outage (i.e. Tentative, Confirmed, Cancelled)
• Contact person
• Entered by (login/password)
• Category (i.e. Direct Connection, Transmission, Generation)
• Recall time
• Comments (free text)

In relation to each published outage the System Operator will record:

• A unique POCP record ID
• The date the outage was published/modified
• The current asessment status (i.e. Assessed, Assessed (C), Being Assessed, Changed, New, Potential EGR Issue)

Business Rule 7

Outage information received by the System Operator will be collated and published as soon as practical.

The System Operator will then assess the information in terms of meeting its Principle Performance Objectives.

Where the assessment identifies a situation where there is a potential failure to meet the Principle Performance Objectives, then the System Operator will publish notifications of those situations (including details and supporting assumptions), and monitor responses to the notifications
