## Post Technical Conference Questions

## 1. State of Bulk Power System Reliability With a Focus on the Changing Resource Mix and Resource Adequacy

                    The transformation of the Bulk-Power System is resulting in significant changes to the nation's power supply portfolio. These changes include increased penetrations of inverter-based resources, the increased use and importance of natural gas generating units for system balancing, and the                           ( print page 81075)                        participation of distributed energy resources. Ensuring the adequate supply of electric energy to service loads during peak hours and during extreme weather conditions is also becoming more challenging in many regions of North America.                

What should the Commission's top reliability priorities be for the next one to three years? What are potential actions the Commission could take to improve reliability regarding these priorities?

(a) What trends and risks identified in NERC's 2023 State of Reliability Report and the 2023 ERO Reliability Risk Priorities Report warrant the most attention and effort?

(b) Resource adequacy traditionally has been characterized in terms of planning reserve margin, which assesses the excess generating capacity required to meet peak load. NERC and industry have recently been discussing the notion of energy adequacy, which assesses whether there is sufficient energy—power over time—to meet customers' energy needs. Is energy adequacy a more appropriate metric to characterize reliability risks given the changing grid?

                    (c) NERC has highlighted essential reliability services (                    *e.g.,*                     frequency response, voltage control, and ramping capability) as core to maintaining reliable operation of the grid. How does the changing resource mix and characteristics of load affect the needed amount and provision of these essential reliability services? What actions, and by whom, are necessary to ensure adequate levels of these services?                

(d) The electric grid is undergoing its most significant changes in a century. How should reliability oversight adapt to this change? Is the existing reliability oversight model flexible and agile enough to help lead the change?

(e) In recent years, reliance on natural gas as a fuel for electric generation has steadily increased. At the Commission's recommendation, the North American Energy Standards Board (NAESB) held forums between August 2022 and July 2023 to discuss the growing interdependence between the natural gas and electric sectors. NAESB issued recommendations to enhance market coordination to address challenges posed by this growing interdependence. Should the Commission prioritize pursuing any specific NAESB recommendation?

(f) Wildfires are no longer considered only a California or Western states issue for grid reliability, as drought conditions are expanding into additional regions including MISO, ERCOT and SPP creating further reliability impacts. What preparations have you taken (or are you considering) to address emerging wildfire and drought reliability risks in your region?

## 2. CIP Reliability Standards and the Evolving Grid

Cybersecurity vulnerabilities and threats continue to evolve at a pace that tests utility cybersecurity programs. These quickly evolving threats present a challenge when assessing whether security controls, including the CIP Reliability Standards, adequately respond to the latest cyber risks. Most utilities and other electric sector stakeholders with mature cybersecurity programs implement an overarching cybersecurity program to oversee all aspects of their cybersecurity activities, including identification of the assets to be protected, staffing, technology selection and procurement, and compliance with the CIP Reliability Standards. However, ongoing and anticipated changes to the interconnected electric grid, such as the shift in the types of energy sources used to generate electricity may disrupt cyber programs. Utilities are digitizing their grids while managing an increasing number of grid-connected devices. As a consequence, utilities require more advanced tools to process and analyze large amounts of data for grid planning, operations, and security. These changes are also leaving uncertainty as to where these digital assets will fit into the cybersecurity regulatory framework and what tools can be used to effectively manage them or even what the future may bring as cyberattacks continue to grow in sophistication.

(a) Discuss the primary security issues facing electric utilities and describe the prioritization of resources and investment. What are some lessons learned and best practices?

(b) With regard to evolving cyber threats, describe how your cybersecurity program identifies and responds to such conditions. When responding, how do you assess the risk posed to your systems by the threats?

(c) Describe the benefits and challenges of implementing and maintaining a cybersecurity program as the resource mix continues to evolve. How does this program interact with actions to comply with the CIP Reliability Standards? How does such a program help to identify and prioritize security concerns, and what actions are taken to address those concerns, including the application of best practices?

(d) Describe how supply chain security and the use of third-party systems, such as cloud services, are addressed in your risk assessments and implemented in the cybersecurity program. What concerns still exist related to supply chain and third-party systems?

(e) What additional actions can the Commission, NERC, and industry take to further protect the grid from security threats, both physical and cyber?

## 3. Reliability Implications of EPA's Proposed Rule on “Greenhouse Gas Standards and Guidelines for Fossil Fuel-Fired Power Plants”

On May 23, 2023, the EPA issued a notice of proposed rulemaking under section 111 of the Clean Air Act. The proposed rule would set New Source Performance Standards for new power plants that run on fossil gas.

(a) Will the rule, if implemented as proposed, affect electric reliability? In what ways?

(b) What tools and processes should the Commission, other federal and state agencies, and industry consider in order to implement the proposed rule? What authority should the Commission and other federal and state agencies have in order to address potential reliability issues that could arise during implementation of the proposed rule?

(c) What existing processes for coordination will enable federal and state agencies, planning entities, and industry stakeholders to share ongoing developments relevant to the implementation of the proposed rule?

(d) What specific tools are currently available to agencies to consider impacts to retail consumers? Are there additional tools that should be developed to consider these issues?
