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…

XCEL Energy Is Saying “No More” to Fossil Fuel Generation by 2030!

By UtilityDive.com – Will the power utility, XCEL Energy, have enough power generation capacity by 2030 in time to abolish all of its coal-fired generating plants? Energy regulators are very doubtful that XCEL Energy can achieve this vigorous goal in replenishing enough clean power to offset their reduction in carbon emissions. The fear is: will XCEL approach a power generation shortfall over the next decade to its electric load demand?

“The South Dakota Public Utilities Commission on Jan. 4 asked Xcel Energy to reconsider shuttering its Sherco and King coal-fired power plants, writing that their premature closure adds to the uncertainty of electric generation resource adequacy in the upper Midwest.”

Pennsylvania Is Moving from Coal Power to Renewables

New-Solar-Power

As coal power and other fossil fuels continue to decline as the nation’s leading power generation source, more power utilities are increasing renewable energy sources such as solar power.

Pennsylvania is replacing their planned fossil fuel generation retirements with clean solar power. The state is helping promote more jobs and job transitions for the green switch from traditional carbon emission type power generation into renewable energy resources.

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.”

DOE: Distributed Energy Resources Need to Be Designed with Cybersecurity Protection

Cyber-protection-of-DERs

By Utility Dive:

Distributed Energy Resources (DERs) present major obstacles in grid reliability and protection against cyberattacks and threats. DOE states “they should be designed with security as a ‘core component.’

An attack on distributed solar or battery storage resources would have ‘negligible impact’ on grid reliability today, DOE said, but the capacity of DERs on the electric system is expected to quadruple by 2025 and the agency warned that each of those systems could be hacked.”

Entergy Plans to Build a 250 MW Solar Farm in Arkansas

Entergy-PV-Solar-Project

By Renewable Energy World:

Entergy is planning to build a 250 MW solar farm project which will end up being Arkansas’s biggest renewable project. It will provide power to “steel manufacturing plants near Osceola in Mississippi County.

The Arkansas Public Service Commission greenlit the 250 MW Driver solar project, which would be built by Lightsource bp, one of the largest solar developers in the world.

Lightsource bp has completed development and permitting of the solar field and plans to build the facility under a build-transfer agreement with Entergy Arkansas.”
