8. 3-Step Emergency Response Storm Mission Statement: Delmarva Power is committed to a storm emergency response system that puts safety first, that restores power to the largest number of customers the quickest, and that tells our customers what they need to know to better plan their lives around the storm event. Step 1 – Preparation Step 2 – Assessment Step 3 – Restoration

9. Power Restoration In the event our system is damaged by severe weather, Delmarva Power repairs equipment which will restore the largest numbers of customers first. Generally, the sequence is as follows: 1. Downed live wires or potentially life-threatening situations and public health and safety facilities without power. 2. Transmission lines serving thousands of customers, 3. Substation equipment, 4. Main distribution lines serving large numbers of customers; 5. Secondary lines serving neighborhoods, 6. Service lines to individual homes and businesses.

10. Restoration Specifics • 1. Transmission Lines • 2. Substations • 3. Three-Phase Distribution Trunk Lines – Power lines you see along major roads and highways (Prioritized considering lines 4 & 5) • 4. Public Health and Safety (Hospitals, EOCs, Police Stations, Fire Houses, Water Supply, etc.) • 5. Priority Customers (Shelters, Assisted Living, Nursing Homes, etc.)

11. Restoration Specifics • 6. Three-Phase Tap Lines – they carry service beyond major roadways and towers toward major developments, schools, businesses • 7. Single-Phase Tap Lines- they carry service through developments to streets, cul-de-sacs, outlying areas • 8. Distribution Transformers- gray cans on poles or green boxes on lawns • 9. Individual Services • 10. Privately-Owned Facilities

12. Power restoration process • Rear Lot or backyard electric infrastructure is challenging: • Limited use of mechanized equipment • Access and terrain • Tree conditions • Customer property • If Tree A falls on a high-voltage transmission line, the substation will lose power, so the entire community will lose power. • If Tree B falls on a distribution line, the northern side of the street will lose power, but the southern side of the street will not. Customers on the northern side of the street will be pressed to understand why their southern neighbors' houses have power. • If Tree C falls on a tap line, the southern side of the street will lose power, but the northern side of the street will not. Customers on the southern side of the street will be pressed to understand why their northern neighbors' houses have power. • If Tree D falls on a service-drop line, only one house will lose power. No other houses on that side of the street will be affected, and that customer will be pressed to understand why. • If Tree E falls on a distribution line, all customers served by that line will lose power.
