American Electric Power’s Experience with
Volt/Var Optimization
2
Volt VAR Impacts on Customer’s Motors
Real Power consumption is 8% lower @ 115V than at
125V
kVAR ↓ ~ 20%
kW ↓ ~ 8%

AEP’s Volt / VAR Optimization Technology Deployments
• AEP Ohio :– 17 circuits in service– Additional circuits being considered to meet EE State Targets
• Indiana & Michigan Power Co.:– 9 circuits in service– Planning to include VVO as an EE Program
• Public Service Company Oklahoma :– 11 circuits in service
• Kentucky Power Co. :– 25 circuits going in service in 2013– Planning to include VVO as an EE Program

Demand and Energy Reduction Results
• VVO technology works as-expected Testing demonstrates ~2-4% energy and demand reduction is
achievable.

“Value” of VVO Compared to
Generation Alternatives
Levelized cost of VVO is in the low part of the Energy Efficiency range due to low initial capital cost and no on-going fuel cost
“LEVELIZED COST OF ENERGY ANALYSIS “– VERSION 3.0 Lazard, February 2009

VVO for Energy Efficiency / Capacity Reduction
• Energy Efficiency (24/7 Operation)– Help meet state Energy Efficiency targets– Receive incentives / participate in DR markets – TRCs 2 to 3 – better than many current programs– Reduce Energy Consumption by Customers– Not limited by “participation rates”– Reduce Emissions – Relieve Transmission Congestion
• Capacity (Demand Reduction Only )– Reduce amount of capacity required at peak / critical times– Short payback period if generation charges are based on peak demand– Defer investment in capacity replacement or upgrades– Engage in DR Market– Relieve Transmission Congestion
