4 FE Internal Requests for Additional Line Support Upon receiving first weather forecast February 28, Met-Ed identified need for 160 supplemental line workers Subsequent change in forecast on Monday, March 2 called for nor easter with significant increase in weather intensity, including heavy, wet snow In response, Met-Ed increased request on March 2 to include 400 additional line workers and 200 damage assessors FE requests mutual assistance support On February 28, FE began participating in daily mutual assistance calls with Regional Mutual Assistance Groups (RMAGs) Discussed resource needs and availability for all FE operating companies FE requested additional line workers through various mutual assistance partners, including: North Atlantic Mutual Assistance Group Southeastern Electric Exchange Great Lakes Mutual Assistance Group 4

5 FE Internal Requests for Additional Line Support Resources were scarce given many member companies located in Mid-Atlantic and New England regions were expected to be and were impacted by Winter Storm Riley and/or Quinn Other FE affiliates also severely impacted In addition to working with RMAG organizations, FE worked concurrently to secure resources from non-rmag utility companies and contractors 85% of line workers secured from non-rmag process Once restoration efforts completed for other FE affiliates, additional FE affiliate line workers became available to assist Met-Ed 5

6 Entire FE Territory Impacted by Winter Storm Riley on March 2 and 3 On morning of March 2, Winter Storm Riley, a powerful nor easter, brought heavy, wet snow to entire Met-Ed service area, reaching 12 inches in some areas Snow fell at very high rate of 1 to 2 inches per hour In Pike County, Riley brought up to 20 inches of snow; Quinn brought up to 14 inches of additional snow As storm escalated, Met-Ed area began experiencing wind gusts of approximately 60 mph, while still snowing Damage and outages throughout FE area, including Met-Ed Hardest hit areas of Met-Ed: Stroudsburg (Monroe and Pike counties) Easton (Northampton) Reading (Berks) York 6
