NYISO releases their 20-year study (2023-2042) showing the power demands are “expected to increase by 50 percent to 90 percent,” according to the assessment. NYISO estimates that over 100 GW of new power generation is required to meet future demands. “The increase will be driven by electrification of housing and transportation sectors, as well as energy-intensive economic development projects.”
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…

By EETimes.com / DesignLines – Fabricating newer integrated circuits is becoming an increasing challenge especially in light of trying to keep up with the rising demand. “Identifying and securing tradespeople who can handle the intricate needs of chip fab construction is something that needs more attention and thought, Shari Liss, executive director of the SEMI Foundation, a nonprofit arm of SEMI that focuses on workforce development programs.”
A new chip manufacturing facility was being constructed in Arizona where the production start-up processes were delayed by nearly a year where the “Taiwan Semiconductor Manufacturing Co. (TSMC) had to delay its production start date to sometime in 2025.”
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.”
By Msn.com / Columbus Dispatch – AEP just announced that it will cutting back on staff which is nearly 2-percent of its workforce and spread-out over multiple states “from Michigan to Texas (AEP’s 11-state region).” The utility “is laying off 270 workers including 170 in Ohio affecting various operations.” The staff reductions will be implemented next month.
AEP stated that the “staff reduction is necessary as we look at the roles needed to best meet the expectations of our customers in the face of higher costs of providing reliable service.”
