RMR Exit Strategies Update TAC November 6, 2003
Next Steps • Exit strategy for B.M. Davis will be presented to TAC and Board in December • Bates and Laredo remain: • Long Term solutions presented by AEP require extensive 345kV upgrades – will require thorough evaluation • Phase I or ERCOT-CFE study provide short term alternatives • TECO and ERCOT are discussing an alternative that would use Frontera as a short-term alternative to Bates • ERCOT continues to receive and validate key input data required for full economic analysis
Contents • Study History and Systems Overview • Phase I and II Studies Scope • Phase I Assumptions and Findings • Interconnection Applications and Market Overview • Enabling Protocols and Agreements • Conclusions and Next Steps
Conclusions • Mutual support benefits to end use customers are recognized in the near term: • Block Load Transfers at Acuña, • Asynchronous ties at Laredo and McAllen • Asynchronous ties afford significant flexibility and reliability to CFE and ERCOT • New interconnections have the potential for providing services beyond reliability, • Facilitate competition and trade • Enhance economic efficiencies
Conclusions (cont.) • Larger ties will have broad policy and economic impacts • Phase II studies will identify larger ties • Cost vs. impact to the energy markets • Phase II involvement of DOE/PUCT and SENER/CRE is recommended
Next Steps • ERCOT to complete economic evaluations of alternatives to RMR services, • CFE and ERCOT to develop system support services agreement, • Ensure ERCOT protocols support and facilitate transactions over CFE/ERCOT ties, • Transmission Service Providers to complete transmission upgrades to support and build the CFE/ERCOT interconnections, • Proceed with the applicable presidential permits for the CFE/ERCOT interconnections
