In a special meeting of SPP’s Board of Directors and Members Committee, SPP’s Comprehensive Review Steering Committee and staff recommended that the board: 1. Accept its report, “A Comprehensive Review of Southwest Power Pool’s response to the February 2021 Winter Storm”. 2. Direct work to begin immediately on recommendations that address root causes (Tier 1). 3. Direct organizational prioritization of work needed to address remaining recommendations. 4. Direct staff to provide quarterly updates on status of progress being made. 5. Direct staff to submit for board approval in October a project plan of activities needed to resolve the tier 1 recommendations. 6. Direct issuance of letters to all generator operators in the SPP region requiring them to inform SPP about their plans to have and maintain fuel necessary to assure availability of all generation treated as accredited capacity for the upcoming winter season. 7. Direct staff to perform additional root cause analyses to explain the failure of natural gas fuel supply during the weather event needed to better inform SPP’s three fuel assurance recommendations.

  • MATTERS Inside This Issue CEO MESSAGE
    AUGUST 2020 “The secret of change is to focus all your energy not on fighting the old, but on building the new.” -Socrates MIDWEST RELIABILITY MATTERS Inside This Issue CEO MESSAGE 3 CEO Message 6 Corporate Values 8 Compliance Monitoring and Enforcement Program 22 Registration, Certification and Standards 25 Bulk Power System Reliability 26 Tips and Lessons Learned 31 Security Corner 36 MRO Interviews the E-ISAC 43 Strategic Update 45 Industry News and Events Midwest Reliability Matters - August 2020 CEO MESSAGE Leading in Uncertain Times What it means to be fearless MRO has undoubtedly undergone a transformation over the past couple of years. We expanded our footprint and doubled the number of registered entities in our region, increased staff such that more than 50 percent have been with the company two years or less, and made several governance changes, including reworking our organizational group structure and increasing the size of our board (notably 14 of 23 directors joined in 2019 or 2020). On top of all of these changes, we (like many others in the industry) transitioned to fully remote work for much longer than anyone would have predicted as a result of the COVID-19 pandemic. All of these changes have happened in my short tenure as President and CEO. Late June marked my two year anniversary serving in this role, and as I reflect back on all that has happened during this time, I find myself wondering, “What does it mean to be a fearless leader?” In considering this question, I happened upon the website www.leadfearlessly.com, which describes fearless leaders as those that embrace change, influence and motivate others to become more fearless, to be open to change, and to grow and adapt.

  • Engrossed Senate Bill 2313—Testimony in Support House Energy and Natural Resources, Chairman Porter March 18, 2021
    PO Box 1856 Bismarck, ND 58502 701-258-8864 1-800-981-5132 www.usnd.org Engrossed Senate Bill 2313—Testimony in Support House Energy and Natural Resources, Chairman Porter March 18, 2021 Chairman Porter, members of the committee, I am Carlee McLeod, President of the Utility Shareholders of North Dakota (USND), and I come before you to testify in support of Engrossed Senate Bill 2313 on behalf of my members, including ALLETE, Montana Dakota Utilities, Otter Tail Power Company, and Xcel Energy. When this bill was heard in the Senate committee, it was in the midst of the weather event (Feb 14-20) that crippled the south and disrupted power in several transmission organizations, including the Southwest Power Pool (SPP), Electric Reliability Council of Texas (ERCOT), and Midcontinent Independent System Operator (MISO). Since that time, we’ve gleaned some clear-cut information, but it will be months of investigation before we see the full picture. Much of what we know is too complicated for the soundbite driven crowd, and messaging of varying levels of truth have filled the void that hasn’t been or can’t be filled quickly or simply. As this body moves to develop germane energy policy, it is imperative that we all understand the same truths about this event and what they mean about our reliability and resource adequacy. Without that common understanding, subsequent policy is unlikely to address any real, substantive issues. Bearing that in mind, we want to thank you for your time and attention last week as representatives from regional transmission organizations (RTOs) and utilities shared information about their experiences during the event.

  • 2014 Summer Reliability Assessment
    2014 Summer Reliability Assessment May 2014 NERC | Summer Reliability Assessment | 2013 i of 45 Preface NERC is an international regulatory authority established to evaluate and improve the reliability of the bulk power system (BPS) in North America. NERC develops and enforces Reliability Standards; annually assesses seasonal and long-term (10- year) reliability; monitors the BPS through system awareness; and educates, trains, and certifies industry personnel. NERC is the electric reliability organization (ERO) for North America, subject to oversight by the U.S. Federal Energy Regulatory Commission (FERC) and governmental authorities in Canada.1 NERC Reliability Standards are the planning and operating rules that electric utilities follow to support and maintain a reliable electric system. These standards are developed by industry using a balanced, open, fair, and inclusive process accredited by the American National Standards Institute (ANSI). While NERC does not have authority to set Reliability Standards for resource adequacy (e.g., reserve margin criteria) or to order the construction of resources or transmission, NERC can independently assess where reliability issues may arise and identify emerging risks. This information, along with NERC recommendations, is then available to policy makers and federal, state, and provincial regulators to support decision making within the electricity sector. NERC prepared the following assessment in accordance with the Energy Policy Act of 2005, in which the U.S. Congress directed NERC to conduct

It articulates the resilience we have collectively experienced over the past year and hope for what the future will bring.
