  1. Reactive Power Federal Energy Regulatory Commission Open Meeting December 15, 2004

  2. Reactive Power Policy • Review of Current Policy • Blackout • New Generation Filings • Staff White Paper in Progress • March 3, 2005 Technical Conference (tentative date)

  3. Reactive Power Sources & Users Sources: Generators, Transmission Equipment (Capacitors, Static Var Compensators) Users: Transmission Lines, Transformers, Loads (motors) Photos courtesy of Areva Transmission & Distribution, Hitachi, and NREL

  4. AEP Methodology Generator and its exciter; Accessory electric equipment that supports the operation of the generator exciter; and Remaining total production investment required to provide real power and operate the exciter * Apply allocation factor to sort annual revenue requirements of these components between real and reactive power

  5. AEP’s Financial Impact • Estimate of all Form 1 reactive power charges is $3.5 to $4.0 billion

  6. Goal of Reactive Power Policy • Promote Reliable and Efficient Infrastructure Investment, Production, and Customer Use

  7. Market Issues • Comparable Treatment of Generation Resources • Interconnection Standards • Reactive Power Planning and Procurement • Supply Incentives • Demand Side Incentives • Public Good

  8. Reactive Power Capacity Options • Cost of Service • Forward Market Procurement • Pay Nothing

  9. Reactive Power Real-Time Options • No Payment within Bandwidth, Opportunity Costs Outside • Strict Opportunity Cost • Market Clearing Prices • Fixed Payment

  10. Major Conclusions • Align incentives with desired outcomes • Pay for reactive power • Apply comparability to reactive power • Treat capability and production differently • Pay more for dynamic than static capability • Review AEP method • Pay all sources same price for production • Mitigate existing market power • Entry may reduce future market power
