2. 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

3. 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

4. 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

5. 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

6. 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 (Project 5.4.3)
Smyrna Line (Project 5.4.4)

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

8. 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

9. 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)

10. 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
