System Data • 409,000 electric customers in Duval, Clay, St. Johns and Nassau Counties • 700 miles of transmission • 240 Kv, 138 Kv, 69 Kv • 3500 MW, 4 plant sites • 100 substations • 303,000 water customers in 4 counties • 1000 wastewater pump stations
JEA and Northeast Florida • Atlantic Coast • Some coastal distribution (salt) • Have Northeaster experience • Consolidated Government -close cooperation • Operate in 4 counties, w/EOC participation in all • Bigger than many Municipals, smaller than many IOUs. • Electric and Water/Wastewater
JEA Hurricane History • Last direct hit was Dora in 1964 • 2004 brushes with Jeanne, Frances and Charlie for combined losses of $10M • Learned much from providing assistance to others (Florida, Mississippi, Louisiana) • Frequent severe summer thunderstorms • Occasional winter storm
Vegetation Management • Trees in North Florida are significant • Three year trim cycle • (Changing to 2 ½ year cycle in 2008) • Managed by 5 professional Foresters • Emphasis on relocation of problem trees • Well structured Asplundh contract • 25 Crews (100 personnel) normally • Additional 25 crews staged prior to storm
JEA GIS • New ESRI system commissioned April 2006 • Full representation of electric distribution, water and wastewater facilities • Electric transmission complete by late 2007
JEA Transmission Structures • No backlog of required pole/structure repairs • 5000 total structures • 1400 wood (mainly 69 KV) • 4 year inspection cycle • Repair as inspected (except major work) • Complete inspection after 2004 storms • 2004 storms - little transmission damage • JEA substations are all loop fed • Integrated transmission ROW mowing and vegetation management
JEA Distribution • No backlog of required pole repairs • Over 50% of JEA electric customers have underground service • All new developments are UG (early 60’s) • Most are fed from overhead feeders • Very little flooding experience • JEA Customer Choice OH-UG conversion option • Pilot Program • 90% customers in defined boundary agree • JEA bills $22/month for 30 years • Two projects in progress
JEA Storm Plan • Day-0 (during the storm) • Crews in hotels (JEA, Tree, Contract) • Selected substations staffed during storm • Dispatch directs efforts • Reclose up to 30 min • Stop work at 40 mph winds (except life threatening emergencies) • Meals provided at JEA facilities • Day 1- 2 • Objective is to restore feeder breakers • Dispatch directs restoration • Engineering teams begin formal damage assessment • Meals provided at JEA facilities • All crews work 16 hour days
JEA Storm Plan • Day 3 and beyond (feeder breakers have been closed) • Work from engineering assessment data • Restoration directed from service centers • Objective is complete feeder restoration including all laterals • Meal Tickets for selected restaurants for mid-day • All crews work 16 hour days
JEA Plan Features • School Restoration • Formal Assessment of each school • Rapid restoration • Communication with school administration • Designation of Essential Intersections • Fuel, groceries, restaurants • Geographic diversity • Communicate with businesses • Priority Restoration
JEA Plan Features • Formal process for assessing and restoring traffic control facilities • Retired employee contracts • Pre-agreed terms • Supervise mutual aid crews • Do assessments • Coordination with wastewater pump stations • Strong Coordination with Local Governments • Jacksonville Consolidated Government EOC • JEA staffs other counties’ EOC
