  5. Information Flow EMA/MLGW Preparation

  6. Preparation Emergency Response Plans (Trigger Points) • The Electric System Emergency Response Plan may be activated whenever any of the following conditions exist: • Natural disaster such as earthquake, tornado, flood, etc. • Predicted temperature above 100 degrees F. • Loss of a gate substation • Loss of a distribution substation where load is not transferable • Loss of a 115 KV pipe type cable • Loss of 12 or more electric distribution circuits • An uncontained network fire • TVA Emergency Load Curtailment - Step 10 • TVA under-frequency relay operation(s) • TVA Notification of a power shortage • Civil disturbance

  10. Mitigation • Unfortunately, there is no shield we can throw up to block the storm. Me have to prepare to get power restored as soon as possible following a storm • Conference Call • Verify that critical response personnel, equipment, and materials are prepared • Make a decision on calling in mutual aid • Monitor the weather • Monitor the outage situation • Activation

  11. MLGW Restoration Philosophy Response Electric service should be restored in sequence from source to load. Repairs should be made at substations associated with TVA entry points then emphasis placed on gate stations and substations and the associated transmission lines between. This restoration should place priority on substations and circuits which affect categories of customers as listed on the next slide. A restoration philosophy should be maintained which will insure an equitable response to the entire community while maximizing the number of customers being restored.

  12. MLGW Restoration Philosophy Response • Hospitals • Water Pumping Facilities • Public Sewage • Airports (MIA and NAS) • Facilities Essential for Restoration; EMA Requests, Major Media, MLGW • Primary Trunk Circuits • Primary Tap Circuits • Life support issues • Police • Fire • Nursing Homes (by number of beds) • Schools (School in/out dependent) • Other Broadcasting (Stations above 100 KW and only if their emergency generation is inoperable.) • Community Convenience e.g.. Major grocery stores, gas stations etc • Secondary (including transformers) • Individual Services

  13. MLGW Restoration Philosophy Response Once restoration proceeds beyond hospitals, water pumping facilities and sewage treatment plants, the priority list becomes dynamic depending on various external contingencies such as weather conditions, duration of the outage, and special requests by EMA. If possible, primary distribution work and secondary service work in an area will be conducted simultaneously and all secondary work should continue even though primary work is complete. Restoration, however, should follow this order with deviations being dictated as needed by upper management and EMA. Areas of convenience, i.e. major intersections, malls, shopping areas, will also be looked at to assist the community in coping with an emergency that lasts several days.
