  1. Reliability Deployment Task Force (RDTF Meeting) November 15th 2011

  2. Updates • Cover 10-27-11 Open Meeting Discussion Items • Offer Floor for RUC Commitments for Capacity Insufficiency • 0 to LSL Energy from ONRUC • Increase RRS by 500 MWs and Decrease NSRS by 500 MWs • Impact of New Power Balance Penalty Curve on PNM

  3. 10-27-11 Open Meeting Discussion Items The following NPRRs were submitted on Nov 9th to implemenet Commission Decision at Open Meeting on October 27 • NPRR426 Standing Non-Spin Deployment in the Operating Hour for Generation Resources Providing On-Line Non-Spin • NPRR427 Energy Offer Curve Requirements for Generation Resources Assigned Reg-Up and RRS • NPRR428 Energy Offer Curve Requirements for Generation Resources Assigned Non-Spin Responsibility

  4. Updates • Cover 10-27-11 Open Meeting Discussion Items • Offer Floor for RUC Commitments for Capacity Insufficiency • 0 to LSL Energy from ONRUC • Increase RRS by 500 MWs and Decrease NSRS by 500 MWs • Impact of New Power Balance Penalty Curve on PNM

  5. RUC Committed Resources Dispatched for capacity (12/01/2010 to 10/31/2011) 8640 Effective RUC Unit Hours • 1787 hrs (20.7%) were dispatched above LSL for capacity • 1560 hrs(18.1%) with prices below $100 • 71 hrs(0.8%) with prices between $100 and $200 • 33 hrs(0.38%) with prices between $200 and $300 • 16 hrs(0.19%) with prices between $300 and $400 • 8 hrs (0.09%) with prices between $400 and $500 • 38hrs (0.4%) with prices between $500 and $3000 • 61hrs (0.7%) with prices greater than or equal to $3000

  6. Updates • Cover 10-27-11 Open Meeting Discussion Items • Offer Floor for RUC Commitments for Capacity Insufficiency • 0 to LSL Energy from ONRUC • Increase RRS by 500 MWs and Decrease NSRS by 500 MWs • Impact of New Power Balance Penalty Curve on PNM

  7. 0 to LSL Energy from ONRUC • 8640 Effective RUC Unit Hours • Average ONRUC LSL is 82 MW , BP is 99.6 MW, HSL is 207 MW • 5741 hrs (66.4%) are at or below LSL (BP-LSL<2MW) • Average ONRUC LSL is 85MW • 2899 intervals (33.6%) are above LSL for transmission or capacity • Average ONRUC LSL is 75.5MW • 3071 Effective Hours with at least one resource on ONRUC status • Average system total ONRUC capacity • LSL is 230.5 MW; • HSL is 581.8MW; • BP is 279.9MW Effective RUC Unit Hours’ is SCED duration, summed up to hour level, for each RUC committed resource when it was online. ‘Effective RUC Unit Hours’ considers multiple units committed for the same hour as different unit hours while ‘Effective RUC hours’ considers it as single hour.

  8. Updates • Cover 10-27-11 Open Meeting Discussion Items • Offer Floor for RUC Commitments for Capacity Insufficiency • 0 to LSL Energy from ONRUC • Increase RRS by 500 MWs and Decrease NSRS by 500 MWs • Impact of New Power Balance Penalty Curve on PNM

  9. Increase RRS by 500 MWs and Decrease NSRS by 500 MWs • Rerun of a few DAM cases showed that there will be more capacity added to SCED due to increased RRS requirement if we assume that the AS Offers submitted into DAM and the AS Self-Schedules doesn’t change with this change in AS plan • RT study assumption - 500MW being removed from NSRS was provided by offline resources and 250MW of the 500MW added to RRS is from Load Resources. • If HASL – 250 < GTDB, the new system lambda would be SWCAP and the time weighted value of the increase in system lambda is summed up as the additional PNM. • Total additional PNM = $7,787  for periods when system lambda increase to SWCAP because of HASL decrease due online capacity being reserved for RRS

  10. Updates • Cover 10-27-11 Open Meeting Discussion Items • Offer Floor for RUC Commitments for Capacity Insufficiency • 0 to LSL Energy from ONRUC • Increase RRS by 500 MWs and Decrease NSRS by 500 MWs • Impact of New Power Balance Penalty Curve on PNM

  11. Impact of New Power Balance Penalty Curve on PNM

  12. Impact of New Power Balance Penalty Curve on PNM • Original CPS Proposal (Submitted to RTDF) : Same as existing curve between 1-10 MW and 30-75. Penalty cost higher between 10-30 and above 75 MW under-generation. • New CPS Proposal (Submitted to PUCT) : Same as existing curve between 1-10 MW. Lower penalty between 10-75 MW, while finishing higher for 75 MW and up. • IMM Proposal : Same as existing curve except for after 50 MW under-generation, the penalty increase from existing $3001/MWh to $4000/MWh • All at $3001 • PNM addition is calculated as the sum of time weighted difference between new penalty and old penalty for each level of Power Balance violation. For the first 3 cases, the assumption is that Power Balance Violation amount is not changing when the curve changed. For the last one since the new penalty is above SWCAP, all offers will be used before violating Power Balance and hence only intervals were the rampable room in SCED offered below SWCAP is less than Power Balance violation were considered. i.e. the effect of increase in prices when the rampable room in SCED offered below SWCAP is greater than Power Balance violation due to clearing more from the offer stack was not considered.
