NIPPC’s IIBA Initiative Agenda 7 December 2007

1. NIPPC’s IIBA Initiative Agenda7 December 2007 • Introduction – independent, integrated Balancing Authority (IIBA) • Overview • Why? • What? • How? • When? • Who? • Costs/Benefits • Tangible Assessment • Intangible Assessment • Operations (user interface) • Optimal Generation Mix • Contractual Structure • Procedural Next Steps • Timeline

2. Introduction • Pacific Northwest Independent Integrated Balancing Authority (IIBA) • Meeting Protocol • Project Participants: • Project Lead: • CECD - Constellation Energy Control & Dispatch • Technical, Operational and Policy Support • Energy Expert Services • NIPPC • Opatrny Consulting • The Energy Group • Versify Solutions • Legal and Contracting Support • K&L Gates • Van Ness Feldman • Generators • NIPPC generators • Potentially other generators

3. OverviewWhy is the IIBA a good idea? • It will enable generators to: • Get paid for what they provide now for free, e.g., frequency and voltage support, reactive supply • Reduce operating expenses, e.g., operating reserves, generation imbalance, integration charges • It will allow money-making opportunities and add value to competitive markets: • Redispatch around transmission constraints • Support the integration of wind (indirectly or directly) • Pool transmission • It will allow generators: • Greater autonomy • To play by market rules, not just BPA’s rules • New opportunities as well as new responsibilities • Last chance to operate as merchants • These opportunities need to be prioritized and sequenced

4. OverviewWhat is the IIBA? • CECD sets-up/implements/certifies the BA • The BA is a reliability function • The BA function requires communications links and AGC • The participating generators separately contract with CECD in order to: • Integrates resources • Maintains interchange-generation balance • Supports interconnection frequency • Manages transmission for these purposes • As a BA, the participating generators will be enabled to: • Sell regulation to support the integration of wind • Participate in operating reserve sharing (through the NWPP) • Self-providing or contracting with third-parties for operating reserves

5. OverviewHow is a BA Established? • Certification Decision • Prepare Questionnaire for NERC and WECC • On-site Visit • Address Minimum Operating Reliability Criteria • Generation Control Performance • Transmission • Interchange • System Coordination • Emergency Operations • Operations Planning • Telecommunications • Operating Personnel and Training • This Process Takes About Six Months; there is a Six Month Probation

6. OverviewWhen does this make sense to do? • Why not now? • There is a recognize lack of business opportunities in the region • There are no plans to aggregate BAs in the PNW • The region is hamstrung by hourly block markets • Transmission constraints are being operated through BPA federal resource redispatch and curtailment • BPA is projecting significant wind integration through 2010 (i.e., 6,000 MW) • The region is now “capacity” constrained • Light-load hours • Heavy-load hours • There is a need for within hour regulation • Renewable portfolio standards are drivers

8. Costs/BenefitsWhat will this Arrangement Cost? • Estimated Cost of Arrangement • Start-up/Implementation/Certification • $175,000 first entrant • $35,000 for each additional • Communications and hardware • Balancing Authority Service Operations • $60,000/month first entrant • $12,000/month for each additional • The CECD Balancing Authority Services Agreement is an instrument already in operation

9. Cost/BenefitsExperience of Other BAs • Value of Load-only or Gen-only BA • Greater control over future commodities purchasing, risk and price management • Eliminate exposure to Generation Imbalance charges • Become a front runner rather than a follower • Take active role in Business Management and Regulatory and Compliance Issues • Actively involved in managing Transmission

10. Cost/BenefitsWhat will this Arrangement Save? • The BA will result in direct savings • Generation Imbalance Charges • Integration Charges ($3.10 – $4.80/MWh) • Operating Reserves (BPA’s rate is $7.93/MWh) • The BA will enable intangible benefits • Provide needed in-hour services • Enhance redispatch opportunities • Reliability • Planning • Pool transmission • Avoid/reduce regulatory interface costs • Improve output profile (wind farm diversity) • Enhance Renewable Portfolio Standard Opportunities

11. Costs/BenefitsHow can benefits be analyzed? • Evaluate BPA Tariff • Generation Imbalance • Avoid Generation Imbalance (BPA) • Band 1: +2 MW or +1.5% of scheduled energy • No charge if returned • Charged, if not returned, at diurnally-differentiated incremental cost • Band 2: Greater than +2 MW or +1.5% of scheduled energy • Charged 110% incremental cost • Credited 90% of incremental cost • Band 3: Greater than +10 MW or +7.5% of scheduled energy • Charged 125% incremental cost; • Credited 75% of incremental cost • Operating Reserves (quantity and price) • Integration Charge (if applicable) • Intangible Benefits • Identify which benefits need further evaluation • Case-by-case, e.g., pooled transmission • Generic analysis using existing data sets

12. Company Overview • Headquartered in Chadds Ford, PA (Philadelphia) • Focused on software applications and tools in two areas of the power industry • Generation asset performance management (V-PerformanceTM) • Trading – LMP and market data analysis (V-TraderTM) • Advanced web-based software architecture with robust and secure data management capabilities and unique user interface • 15 customers and growing • Partnership with Constellation Energy Control and Dispatch

31. Who are the Anchor Tenants? • Any resource can be the anchor tenant • Needed to initiate the BA certification process • Realize cost savings • Fossil fuel resource can support wind integration • In-hour shaping • Between hour shaping • Back-off generation during off-peak hours • Wind can provide other opportunities • Enable RPS opportunities • Further cost savings through avoidance of integration charges • Potential wind farm diversity to improve capacity factor

32. Contractual Structure • Contractual Arrangement • The Balancing Authority • Execute BA Services Agreement • The BA will not engage in commercial transactions • The BA will offer services to enhance the value of member generators • The BA generators can be “interconnected” through transmission and dynamic schedules • The Generators • Execute the BA Services Agreement (cross contracts) • The Generators will sell to end-users • The Generators will address pooling opportunities • Advise was to not limit participants • No “Anti-trust” issues identified • The purpose is to facilitate commerce – enhance competition • A bid structure will need to be designed for services • Information sharing as long as such doesn’t impact competition

33. Procedural Next Steps • Simple Start • Stage this Concept • Arrange Policy Representation (NIPPC) • Allow for full Expansion • NERC certification • Process requirements • WECC recognition • Process requirements

34. Procedural Next Steps • The IIBA would need to • Become a member of the WECC • Become a member of the PNSC • Become a member of the NWPP • Reserve Sharing Group • Consider signing the Western Interconnection Agreement (release of liability) • Consider joining ACE Diversity Interchange

35. Timeline • Other questions? • Define policy/PR needs for this effort. • Execute Balancing Services Agreement (December 2007) • Initiate certification process (January 2008) • Engage in BPA’s wind integration pilot (Q1 or Q2 2008) • Other “next steps”?
