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.”

China Reveals World’s Biggest Offshore Wind Turbine

China-Wind-Turbine

By PowerMag:

“Two Chinese companies announced production of the largest offshore wind turbine built to date, a 16-MW unit developed by China Three Gorges (CTG) and Goldwind.

The groups on Nov. 24 showed off the turbine at a factory in Fujian province. The turbine has a 252-meter rotor diameter, with a 50,000-meter sweep area. The hub height is 146 meters.

Lei Mingshan, chairman of CTG, in a statement said, ‘the successful rollout of the 16-MW unit marks that my country’s wind power equipment industry has achieved a historic leap from ‘following’ to ‘running alongside’ and then to ‘leading’, creating the latest benchmark for the development of global offshore wind power equipment.’ ”

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.”

Minnesota governor accelerates state’s carbon-free power target 10 years, to 2040

Minnesota-Carbon-Free-Electricity

UtilityDive – Minnesota Gov. Tim Walz, D, on Thursday proposed a series of policies that would bring the state to 100% carbon-free electricity by 2040, a decade earlier than the goal he proposed in 2019.

His proposed policy goals follow a report from the Minnesota Pollution Control Agency issued earlier this month, finding the state is not on track to meet its previous goals of reducing economy-wide greenhouse gas emissions 30% below 2005 levels by 2025, and 80% by 2050. Overall, greenhouse gas emissions have declined 8% since 2005, according to the agency’s latest data, which measures emissions through 2018.

Minnesota’s largest investor-owned utilities (IOUs) — Xcel Energy and Minnesota Power — are pursuing 100% carbon-free energy by 2050 targets, and said their plans are more realistic.

Dominion files plans with federal regulators for 2.6 GW offshore wind project, largest in US to date

Dominion-Wind-Energy

UtilityDive – Dominion Energy has filed the construction and operations plan for its 2.64 GW offshore wind project, with construction expected to start off the coast of Virginia in 2024. The anticipated filing with the Bureau of Ocean Energy Management (BOEM) was made after Dominion completed construction of a 12 MW pilot offshore wind project in Virginia — the first offshore wind turbines approved by regulators in federal waters. The company expects the BOEM review process for the largest offshore wind farm in the country announced to date to take about two years.

The offshore wind generation capacity is a large component of the utility’s clean energy plan, to meet the state’s rigid decarbonization standards in the Clean Economy Act passed earlier in 2020. Pending approval of the project by the State Corporation Commission and federal regulators, the project would provide renewable electricity to power up to 660,000 homes upon completion in 2026.
