• NPRR1278 aims to establish advanced grid support as an ancillary service similar to NOGRR272 but via an RFP process.
• The NPRR allows flexibility for ERCOT to adjust service requirements annually based on new technologies and capabilities.
• Concerns were discussed regarding the difference between mandating a service versus offering it as a competitive service.
• The proposal was seen as offering no immediate risk to reliability regarding frequency and voltage control.
• Stakeholder discussion highlights the need for further review and potential adjustments based on reliability and market practices, specifically in section 8 of NPRR1278.
• Fred Huang and others acknowledged the cost implications of meeting the new performance standards for IBRs.
• Debates centered around whether the advanced grid support should be technology-neutral or focused solely on IBRs.
• Participants discussed the potential market dynamics and compensation mechanisms, emphasizing flexibility and the lack of retroactive requirements for existing resources.
• Further evaluation is needed to determine the required capabilities and how ERCOT will procure the necessary services via the RFP model.
• Concerns were expressed about ensuring sufficient inertia and managing state-of-charge for battery resources.
• The discussion will continue, with OWG seeking more input and a deeper review of NPRR1278 in future meetings.
