Electric Utility Master Plan Scope It is prudent utility practice for a utility system to be reviewed periodically for performance The task included: Analysis over a 10-year planning period Normal Loading conditions Single Contingency conditions

Electric Utility Master Plan Scope The task recognized: System configuration changes and improvements Shifts in load growth patterns The task analyzed: Present load level Two future load levels

Overview / Historical Load System: Three substations- Airport, Field Street, Smyrna Five power transformers Firm emergency rating 120 MVA Historical Load: 88 MW in 2006 to 101 MW in 2016 400 million kWh in 2006 to 441 million kWh in 2016 Relatively flat 2006 through 2014

Transformers and Feeders: Load Projections System: Forecast 1 (lower) 1.0% Growth to 105 MW in 2025 Forecast 2 (higher) 3.0% Growth to 128 MW in 2025 Transformers and Feeders: Forecast 1- 2.6% for Smyrna, 0.53% for Airport and Field St Forecast 2- 6.3% for Smyrna, 2.1% for Airport and Field St

Analysis – Normal Loading with Growth Loads above 100%: 2015- no issues 2025 Forecast 1- 2025 Forecast 2- Airport Sub transformer (Project 5.4.1) Smyrna Sub transformer (Project 5.3.1) Field Street Line 25 (Project 5.4.3) Smyrna Line 12 (Project 5.4.4)

Analysis – Single Contingency Feeder Contingency Loads above 100%: Airport Line 16 (Project 5.4.2) Field Street Line 7 (Project 5.5.5) Field Street Line 26 (Project 5.5.2) Airport Line 17 (Project 5.5.1) Smyrna Line 11 (Project 5.5.4) T-Line and Transformer Contingencies Smyrna to Field St circuit (Project 5.2.1 and 5.2.2) Smyrna Sub transformer (Project 5.3.1)

Recommendations / Program of Improvements Identified by Timing: Short-Term (< 5 years) Medium-Term (5 to 10 years) Long-Term (10 years +) Identified by Type and Priority: Growth-driven project Capital project Combination Growth / Capital project Priorities 1, 2, 3 within each Type

Recommendations / Program of Improvements T-Line Contingency Recommended Option: Tap the Airport 115 kV circuit, construct second pole line into Field Street, approx 2.4 miles (Project 5.2.1, $2.00M, 100% Capital) Expand 115 kV portion of Field Street Sub for new line terminal (Project 5.2.2, $891k, 100% Capital) Smyrna Add Capacity Recommended Option: Procure two new substation power transformers and five new distribution feeder circuit breakers Expand and reconfigure distribution portion of Smyrna Sub (Project 5.3.1, $3.88M, 75% Growth 25% Capital)

Recommendations / Program of Improvements Four Short-Term Priority 1 (High) Distribution Projects Five Short-Term Priority 2 (Medium) Distribution Projects Four Medium-Term Distribution Projects Five Long-Term Distribution Projects
