Training for Regulators Amidst an Evolving Electricity System
America’s bulk power system (BPS) is a large interconnected electrical system comprised of generation and transmission facilities, operated by various control systems. As the BPS continues to evolve amidst the ongoing energy transition, NARUC has been offering virtual training sessions on relevant information aimed at electric utility regulators since 2021. These resources have been developed by NARUC, with support from the National Association of State Energy Officials (NASEO), the National Association of State Utility Consumer Advocates (NASUCA), and the U.S. Department of Energy. NARUC also recognizes additional current and past partners:
These BPS courses are designed to introduce non-technical attendees to key technical concepts and their practical applications amidst an evolving electric system. Subject matter experts offer insights on topics identified and prioritized by the regulatory community.
Upcoming Modules, all held from 2:00 to 4:30 p.m. ET:

This session provided an overview of what integrated planning is and why it is important. It highlighted some examples to date spanning from a vertically integrated utility to a single-state and a multi-state ISO.
This session started with current practices and presented the benefits and challenges of incorporating transmission, distribution, DERs, and flexible loads into generation capacity expansion optimization.
This session explored capabilities and shortcomings of existing tools, data, and processes. It also presented leading developments to move towards co-optimization of generation, transmission, and distribution, including the integration of economic and reliability tools and improved model interoperability across temporal and spatial dimensions.

How do DERs impact real-time operations? If my state adopts the recent IEEE 1547 interconnection standard, will that fix the negative impacts of DERs on the bulk power system? How can DERs be used to reduce the need for new capacity resources?
What is an inverter-based resource and why should I care? What are the differences between grid-forming inverters and synchronous condensers; which technologies will be important in the future? Is low-inertia the main concern; will we run into such conditions soon?
How do wind, solar, and DERs change reserve requirements? What are essential reliability services and can you get them from wind, solar, and DERs? What role will hybrids play in the future? What is the future of gas/electric coordination? What are options for system flexibility?
How should we think about resource adequacy in a future with high levels of wind and solar? Is the planning reserve margin concept still valid? How does resource adequacy relate to recent CAISO and ERCOT events? What do batteries offer in providing resource adequacy?
