How Is the Major Heatwave Affecting the US Power Grid?

NERC-2024-Summer-Assessment

With the rising temperatures across most of the US and many cities experiencing over 100 degrees Fahrenheit, stresses the overall electric power grid. Power utilities are experiencing summer peaks in larger electric load demand by keeping up with consumers’ air conditioning units running around the clock.

The Tennessee Valley Authority (TVA), one of the nation’s largest utilities, provides electricity across a 7-state region (80,000 square miles) in the Southeast for over 10 million users. TVA has a total generation capacity of 32 gigawatts (GW) with the option to purchase and wheel additional GWs to customers from neighboring utilities. In the past, TVA has experienced winter peak load demands that created system disturbances that resulted in temporary and very short rolling blackouts in some cities/areas to maintain power grid reliability. Temporary load shedding outages were necessary for balancing the system generation capacity with the excessive peak load demand by ultimately protecting the integrity of its entire electric network.

Moving forward, TVA has spent millions in power grid improvements and efficiency upgrades to support increases in future peak load demand. TVA’s integrated resource plan (IRP) will focus on continued grid improvements with plans to add up to 10 GWs of solar renewable power generation by 2035. Continue Reading…

The North American Electric Reliability Corporation (NERC) released its “2024 Summer Reliability Assessment, “ May 2024, detailing and “identifying areas of concern” for the nations North American power grid during extreme summer conditions. NERC named power regions/entities that may experience power generation capacity shortages during summer peak load demands. Continue Reading…

TVA Sees a New Record Winter Peak Load Demand in Early 2024!

TVA-Winter-Jan-2024
By Tennesseestar.com

By PowerMag.com – On Wednesday, January 17, 2024, the Tennessee Valley Authority (TVA), one of the nation’s largest power generation and transmission utilities in the southeast, reached an all-time record-breaking winter “peak power demand of 34,526 MW,” while the average temperature across the Tennessee valley region (7 state territory) was at “4 degrees F.”

TVA’s previous peak power demand record was set in August 2007 reaching a summer peak power “demand of 33,482 MW.” TVA also set another previous “winter peak power demand record at the end of 2023 (December 23, 2022) during the Winter Storm Elliott with a demand of 33,400 MW,” which spiraled into power generation shortages resulting in a series of rolling blackouts across the region.

With the higher peak power demand forecasted in early 2024, “TVA urged its 10 million customers to be aware of their power consumption” and to cut back on energy usage during the early morning hours. At this time, all of TVA’s generating units were operating adequately while maintaining a stable electric power grid. “TVA had invested $123 million over the past few months” in better preparation for this winter compared to the winter just a year ago.

With the increases in power generation retirements in both coal powered and nuclear energy plants, presents major reliability concerns to the electric infrastructure. There is over “83 GW of fossil fuel and nuclear generation” in planned retirements over the next decade that could wreak havoc on the nations power system.

NERC indicated in their “Long-Term Reliability Assessment” that this “creates blackout risks for most of the United States.”

Multiple Power Utilities Affected by Recent Cyber Attacks!

Power-Utilities-Cyber-Attacks

The US Electrical Grid Infrastructure continues to be vulnerable to cyber attackers and foreign nation state adversaries in attempts to bring havoc on power systems that supply other critical infrastructures.

Cyber security protection continues to be a major focus on power utilities and other critical systems. These cyber threats continue after power companies and their contractors as in the recent attacks.

FERC Tightens Regulations for Inverter Based Resources

FERC-Regulatory

By Renewable Energy World:

The Federal Energy Regulatory Commission (FERC) issued “new mandatory standards for inverter-based resources (IBRs) in an effort to enhance the reliability of the bulk electric system. IBRs are solar photovoltaic, wind, fuel cell and battery storage resources that use power electronic devices to change direct current power to alternating current power, to be transmitted on the bulk-power system.

In its November 17 action orders, FERC focused on three IBR-relateded actions:

  • An order directing the North American Electric Reliability Corp. (NERC) to develop a plan to register the entities that own and operate IBRs;
  • A Notice of Proposed Rulemaking to direct NERC to develop reliability standards for IBRs that cover data sharing, model validation, planning and operational studies, and performance requirements; and
  • An order approving reliability standards that are related to IBRs, which NERC proposed earlier in 2022.”

National Cybersecurity Awareness Month (October)

NERC

By NERC: “WASHINGTON, D.C. – October is Cyber Security Awareness Month, which highlights some of the emerging challenges in the world of cybersecurity. NERC’s Electricity Information Sharing and Analysis Center (E-ISAC) is supporting the campaign as a Cyber Security Awareness Month champion. This year’s theme, “See Yourself in Cyber,” focuses on four primary best practices: enabling multi-factor authentication; using strong passwords and a password manager; updating software; and recognizing and reporting phishing.”

“This year’s campaign is very timely as evidenced by the recent spate of high-profile hacks that often start with credential theft,” said Manny Cancel, NERC’s senior vice president and CEO of the E-ISAC. “It demonstrates the importance of organizations having strong information technology protocols and procedures in place combined with a need for employee training and awareness. NERC and the E-ISAC support a month focused on raising awareness of cyber security, which coincides with our annual grid security conference GridSecCon, cohosted with ReliabilityFirst this year.”

“With rising cybersecurity threats to the United States energy infrastructure and the reliability of the bulk power system, the need for shared heightened vigilance cannot be underestimated. The E-ISAC continues to collaborate, coordinate and communicate with industry stakeholders and government partners to collectively enhance the cybersecurity posture of the North American grid. The E-ISAC encourages its members to practice good cyber hygiene and always maintain a Shields Up posture. Good practices across both information technology and operational technology networks include: applying security patches as soon as possible, maintaining strict access management, baselining systems, encouraging strong passwords and multi-factor authentication and sharing cyber incident information with the E-ISAC. And, finally, E-ISAC stakeholders who are not yet members are encouraged to join find out more information at www.eisac.com.”
