Manager, Transmission Planning Department

2. Regional Transmission Expansion Planning Process
Ongoing and cyclical
15 year planning horizon
Comprehensive and Holistic
Collaborative

3. Regional Planning Process - Reliability
Apply sensitivity analyses to reliability criteria
5 year
10 year
15 year
Include all required upgrades at all voltage levels in RTEP
kV new construction included in RTEP
Identify kV new construction requirements and continue to re-evaluate each year
kV upgrades included in RTEP
Pursue Right-of-way acquisition for kV projects

4. Uncertainty – What are the drivers?
Load Growth
Local Historical Weather and Load Data
Local Econometric Forecasts
Generation
Received over 1000 interconnection requests since 1997
Received requests to interconnect over 200,000 MW since 1997
“S” Queue - closed on 7/31/07
124 projects
Approximately 18,000 MW generation
Deactivations
Merchant Transmission Interconnection

5. Current Transmission Expansion Drivers
Generation Retirements and Exports to NYC

6. 500 kV Overloads

7. Allegheny Mountain Corridor
Build a new 765 kV transmission line from the John Amos substation to Bedington substation and extend a twin circuit 500 kV line to a new substation in Kemptown near the Doubs-Brighton and Brighton-Conastone 500 kV lines.
15 year analysis shows that this alternative has the greatest impact on the overloads shown on the previous page.
Expected in service: 6/1/12
Approximate cost: $ 1.8 Billion
