DOCUMENT NUMBER: SOP450

TITLE: Summit Station Power Transfer Procedures

PURPOSE:

Provide a procedure for the safe transfer of electrical power from the currently running power generation method to a different method. There are several different options as there are 3 methods of generating power at Summit. This SOP outlines the procedures to transfer power between the 3 different power plants.

BACKGROUND:

Emergency power at Summit Station consists of a single Perkins generator set capable of supporting a 75kW load for a sustained period of time. Power from the emergency generator, the SMG generators, or the MT is connected to station feeders in the Distribution Shack (D- Shack) through a series of breakers.

A station-wide power outage is required to transfer to the emergency power generator as a power source or to transfer from the emergency power back to station power. Emergency power and normal station power cannot be connected at the same time.

Safety Caution: This procedure requires disconnect and reconnect of high voltage electrical power to multiple locations. Good communication and acknowledgement by all parties is essential to ensure the operation is carried out safely.

DETAILS:

Any person conducting or assisting with the transfer of power must be trained on and understand this procedure PRIOR to work commencing. The Station Supervisor will assign roles to designated persons prior to power transfers.

Radio communication must be confirmed and maintained between the garage and the D-Shack. If communication is lost for any reason, the transfer will be stopped until good communication is established and confirmed.

Pre-Transfer Notification Requirements:

Advanced notice and announcements prior to actions are required for planned transfers for operational or training purposes.

The mechanic will notify the site supervisor of the need for a planned outage. The supervisor will coordinate the notification to science groups and is responsible to ensure the local announcements occur:

• 48 hours minimum (72 preferred): Email notification to science groups (via the

existing distribution list) to allow input on scheduling conflicts or concerns.

• 24 hours: Email notification to confirm planned time and duration.

• 1 hour: Radio announcement stating time and expected duration.

• 15 minutes: Radio announcement stating time and expected duration.

• 1 minute: Radio announcement to state outage will begin in 60 seconds.
