Procedures for designating a Scheduling Entity & Operating and Scheduling Protocols For Scheduling Entities

Transcription

1 Procedures for designating a Scheduling Entity & Operating and Scheduling Protocols For Scheduling Entities Listed below are the procedures for becoming a Scheduling Entity for a Transmission Customer as well as the Operating and Scheduling Protocols for Scheduling Entities (SEs), Load Serving Entities (LSEs) and Generation Providing Entities (GPEs), operating in the NV Energy (NVE) Balancing Authority Area (NEVP BAA). The information provided below is meant to supplement but not supersede the information provided by NERC, WECC, NAESB, and Schedule 1 of the OATT regarding Scheduling Protocols. DEFINITIONS Purchasing-Selling Entity (PSE): The entity that purchases or sells, and takes title to, energy, capacity, and Interconnected Operations Services. PSEs may be affiliated or unaffiliated merchants and may or may not own generating facilities. Load Serving Entity (LSE): The responsible entity that secures energy and transmission service (and related Interconnected Operations Services) to serve the electrical demand and energy requirements of its end-use customers. Generation Providing Entity (GPE): The PSE who is responsible for providing the source generation from owned, affiliated, or contractually bound generation. Scheduling Entity (SE): Pursuant to Schedule 1 of the OATT, an entity that the Transmission Customer designates for the purposes of communicating with the Transmission Provider regarding all scheduling of the Transmission Customer s loads and/or resources and for coordinating and allocating curtailments and interruptions in Load and the altering of schedules at the request of the Transmission Provider. Such SE must be registered as a single PSE on the NAESB Electric Industry Registry (EIR). Note: Scheduling Entity is synonymous with Scheduling Coordinator and Network Integration Transmission Service (NITS) Agent. WHAT ARE THE QUALIFICATIONS TO BE A SCHEDULING ENTITY/SCHEDULING COORDINATOR/NITS AGENT The Transmission Provider will accept requests for transmission reservations and schedules for Energy and Ancillary Services only from Scheduling Entities (SE) having met the following requirements. 1. Demonstrate that the SE Applicant is certified as a Scheduling Entity by the California Independent System Operator ( California ISO ) or provide all of the information included in 18 CFR 2.2 including but not limited to the following: a. The Identity, address, telephone number and facsimile number of the SE Applicant; b. A statement of qualification that will demonstrate to the Transmission Provider reasonable satisfaction that the SE Applicant is capable of performing the functions of a Scheduling Entity; and c. A statement that the End-Use Customers represented by the SE Applicant are, or will be upon commencement of service, Eligible Customers under the Tariff. 2. If the SE Applicant has provided sufficient evidence that it is certified as a Scheduling Entity/Coordinator by the California ISO, then the Transmission Provider will immediately certify the SE Applicant as a Scheduling Entity for NV Energy and can, upon the Scheduling Entity s compliance with the above requirements, commence reserving capacity and scheduling transmission and ancillary services pursuant to the Tariff on behalf of their own entity. The Transmission Provider will review the application of SE Applicants who have not been or are not currently certified as a Scheduling Coordinators by the California ISO and may request additional information, clarification or 1 of 6

2 documentation from the SC Applicant needed to process the application. The Parties will work in good faith to provide the necessary information to grant the SE Application. NETWORK AND TRANSMISSION CUSTOMER RESPONSIBILITIES WHEN DESIGNATING A SCHEDULING COORDINATOR 1. A Network or Transmission Customer must provide the Transmission Provider a 30 day notice prior to designating a new Scheduling Coordinator. 2. The Network or Transmission Customer will fill in the attached Contact Information located at the end of this Business Practice and the Contact Information to: NVScheduling@NVEnergy.com 3. Once NV Energy receives the new Scheduling Coordinator Contact Information, NV Energy will work informally in assisting the customer to get the new Scheduling Coordinator set up in OASIS with OATI as a NITS agent. OPERATING AND SCHEDULING PROTOCOLS 1. The primary method for submitting the Request for Interchange (RFI) shall be an e-tag. 2. Either the Transmission Customer acting on its own behalf, or its designated SE, will at all times have present a designated member of its staff who will be responsible for operational communications with the Transmission Provider and who will have sufficient authority to commit and bind the Transmission Customer. 3. There shall only be one SE per customer. NEVP shall only accept schedules or schedule changes from the Transmission Customer or the customer s authorized designated SE. 4. The Transmission Customer shall designate its SE by providing written notification to the Transmission Provider as soon as practicable, but not later than thirty (30) days prior to the effective date. The Transmission Customer shall make any change to its designated SE in writing as soon as practicable but not later than thirty (30) days prior to the effective date of such change. The Transmission Customer shall be allowed a maximum of two changes to its SE in a 12-month period. 5. The timing for submitting e-tags shall be in accordance with the WECC Preschedule Calendar (posted on the WECC website), prior to the scheduling hour. Tags submitted beyond those deadlines are subject to denial. 6. In the event the SE s e-tag Program is out of service, it shall request another PSE to create the tag. Where an entity other than the designated SE is submitting the tag, the customer s SE must be referenced on the tag. If all e-tag systems are down, the SE shall notify NEVP s Reliability Dispatcher as well as the adjacent Balancing Authority Areas (BAAs) involved in the interchange transaction of the outage by phone and follow the WECC Regional Criteria, as applicable. 7. All statically and dynamically scheduled transactions shall have an IMPLEMENTED tag, including intra-baa transactions. 8. Entities operating within the NEVP BAA shall coordinate EIR registration of Entity, Source and/or Sink names with NEVP s Transmission Schedulers prior to any TSR requests or NITS applications on NITS on OASIS and allow a minimum of ninety (90) business days in advance. 2 of 6

Any e-tags which are incomplete or contain incorrect information will be DENIED. 10. All transmission service information and corresponding NERC priority must be correctly entered on the tag. 11. The Transmission Customer will be held responsible for any imbalance that may occur as a result of its failure to submit a correct and complete e-tag. 12. Transmission Customers who have e-tags which are incomplete or incorrect at the close of pre-schedule will be required to submit tags in real-time. 13. The SE shall be responsible for adjusting the tags for schedule changes (i.e. change in generation source or for economics). 14. All transactions initiated from a Non-System Generator within the NEVP BAA shall be tagged firm contingent (G- FC). 15. If the SE has made arrangements for the self-supply of reserves the SE shall provide a separate tag (capacity type tag) in order for the transaction to be firmed up and be considered firm (G-F). Without this separate tag, the transaction would be considered Firm Contingent (G-FC). 16. NEVP will determine whether it must carry load for reserves sinking in its BA based on e-tags. 17. Tags submitted with the energy product codes of G-FS or G-F code shall be treated as Firm with the Generation Control Area (GCA) on the tag carrying reserves. Tags submitted with energy product codes other than G-F or G- FS shall be treated as Non-Firm and NEVP will supply reserves and charge the entity accordingly. Tags using an intermediary Balancing Authority (BA) as the entity carrying the reserves will show the energy as Non-Firm and will require the submission of a separate Capacity Type tag at the time the initial tag is submitted to firm up the energy. The Capacity Type tag will show the GCA that is carrying the reserves and show the transmission path with transmission capacities reserved. If the Capacity Type tag is not approved the energy will be considered Non-Firm. ADDITIONAL PROTOCOLS FOR GENERATORS OPERATING IN THE NEVP BAA: 1. Plant Start-up: Generator Operators shall provide one-hour notice to the NEVP Balancing Operator prior to startup. The Generator Operator shall request permission to come on-line immediately prior to synchronization and shall notify the NEVP Balancing Operator of the expected Generator output (MW). Generators with static schedules shall be on-line and at minimum load no later than 10-minutes prior to the hour (the start time of the ramp) unless otherwise agreed to by NEVP. If the generator is unable to do so, all associated static schedules shall be terminated and the start-up process shall begin again the following hour. 2. Following the contingency outage or partial loss of generation, the Generator Operator shall immediately notify the NEVP Balancing Operator and the Generator s SE of the ETR (estimated time of return), cause of trip or derate, and the loss of generation (MW). 3 of 6

4 3. There shall only be one SE per Generator. 4. The SE shall be responsible for immediately adjusting and removing all tags associated with changes to the generation schedule, including unit trips or partial loss of generation. 5. The SE shall not submit schedules that exceed the established ramp capability of the plant within the standard WECC ramp time (20 minutes). Schedules submitted in excess of the physical ramp capability shall be denied. For example, if the plant ramp rate capability is 10 MW/min, then the SE shall not submit schedules that exceed 200 MW (= 10 MW/min * 20 min). 6. The SE is responsible for ensuring that the information on the tag is correct. The SE shall ensure that all transactions initiated from a Generator within the NEVP BAA are tagged firm contingent (G-FC), unless otherwise agreed to by NEVP. If there is a conflict between a posted business practice and the OATT, the OATT shall govern.
