2. 2 PMO Update  Agenda  Recent Project Developments  Project Funding Changes  NPRR Review Status  CBA Review Team

3. 3 PMO Update  Recent Project Developments  EDW Go-Live Project — EDW EMMS Extracts (PR-50005) Scope: Transitioned PUCT, Market and Public EMMS extracts from the legacy Data Archive to the ODS (Operational Data Store) environment utilizing the EIS (Enterprise Information System) Data Delivery Model Deliverables: 4 extracts for Market Participants and 12 extracts for the general public Timeline: January 2005 – January 2007 Go-live was 1/15/2007 Cost: $315k Estimate in mid-2005 was $327k  Transfer of funds from Texas SET 3.0 to TCC2 Finish-out and Annex Construction (see next slides)

4. 4 Managing Project Funding Changes  Process for Managing Changes in Project Funding  Individual CARTs have authority to make project budget changes <$100k  They must still manage within their allocated CART budget  Project budget changes >=$100k go to the ERCOT Strategic Review Team (directors) for review and approval  CARTs bring forward proposals for reallocation of funds (including the CART which was releasing the funds in question)  Project budget changes >=$500k go to the ERCOT Executive Committee for review and approval  Executives act on the SRT recommendation (affirm/change)  Project budget changes >=$1M go to the ERCOT Board of Directors for review and approval  Final ERCOT recommendation goes before the BoD

5. 5  Important Considerations  Every effort is made to NOT negatively impact PUCT and market projects  Projects expected by the market in the current year  Projects just below the cutline are considered for funding  Critical projects emerge between yearly prioritization cycles that need to be addressed on a near-term basis  Market input is derived from project ranking on PPLs and input from appropriate CARTs  Reallocating funds between CARTs is preferred over requesting additional project funding from the BoD  This is especially the case early in the calendar year  Communication of decisions occurs through usual channels  Market Subcommittee reports (PRS, RMS, etc.)  TAC and Board reports Managing Project Funding Changes

6. 6  Texas SET 3.0 Funding Transfer  Texas SET 3.0 was estimated at $1.63M going into Execution  PPL budget was $3.75M  $2.1M variance was reported to SRT by RO CART  Reasons: Project consolidation, reduced external labor, hardware not needed  RO presented a proposal to use some of the funds within RO  CO presented a proposal to use the funds for facilities needs  Build out unfinished TCC2 space, reconfigure cubicles to increase cube count, construct 12,000 sq. ft. annex/warehouse  The SRT and Executive Committee decided the best course of action was to reallocate the funds to CO  No impact to planned RO market projects to be started in 2007; possible, but small, impact to delivery in 2007  These decisions occurred very quickly due to timing constraints relating to the February Board of Directors meeting  Reported to RMS on 2/14  Board to review proposal on 2/20 Managing Project Funding Changes
