Hi Everyone,


I’m not sure if we’re supposed to provide comments on these documents prior to Friday’s meeting – so, I’m providing comments just in case.


For KP3, based on feedback at the last meeting, I’ve introduced language to truncate the ASDCs at the corresponding AS Plan amount – so, RUC will not procure AS greater than minimum AS Plan amounts. E.g. if Non-Spin ASDC goes from say $1800/MW to $200/MW for AS Plan amount of 1000MW - then RUC will use this truncated ASDC. I also require that RUC apply a floor to Startup Cost (TBD), Min Energy Cost (TBD) and EOC. EOC Floor would be the current $1,500/MWh. This would imply that if there is scarcity, RUC would at most procure the first 100-200MW of Non-Spin (if any) since the ASDC does not justify the cost once offer floors are applied.


For KP1.5, I’ve clarified that Regulation Service deployments will always be Resource Specific under both alternatives – the only difference is whether the Resource Specific amounts are based on optional normalized Participation Factors (PFs). There is no obligation to use Participation Factors and the default would be as specified in Alternative 1. The concern raised at the last meeting that normalized PFs may take time to compute within the 4-second LFC cycle is addressed by having normalized PFs being provided to LFC for each SCED interval. Again, maintaining PFs does not alter the economic efficiency of RTC and can increase efficiency by QSEs providing deployed energy in an economic manner taking into account storage levels in its portfolio of storage and controllable load assets.


There was also a good suggestion that we introduce Energy Storage Group (similar to IRR Group) that can be utilized by a group of Energy Storage assets for GREDP and Base Point Deviation purposes. I’ve added a paragraph to incorporate this suggestion.

Good morning everyone,


I wanted to quickly let folks know that the key principle documents in the updated template format have been posted on the 6/21/19 RTCTF meeting page.  We plan to have the full agenda posted tomorrow and these documents will be discussed as part of that agenda.  Additional material for the meeting will likely be posted next week.


We look forward to seeing you all on the 21st
