In the U.S., with the increased connections to the power grid by cleaner, greener, carbon-free electric generation, and renewable resources, the FBI has issued a warning for the nations power system. “The federal government is becoming more concerned about vulnerabilities with new energy systems being a target for cyberattacks.”
Adversaries and hackers are looking at potential weaknesses in the power sector with “private and individual owners of renewable power systems.”

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.”
PowerMag.com (Sally Jacquemin):
“When DERs and other devices are logically grouped or aggregated, they can form a virtual power plant, or VPP, providing load flexibility for grids that are reaching capacity or economic value with energy market participation, like a traditional power plant.” VPP’s can help prevent current and future plans for adding on new generation plants and can be considered as a method for shrinking future “greenhouse gas emissions.
As power demand increases beyond current power plant capacities and clean energy goals are accelerated, power generation sources of the future will start to look different. In fact, some of these new components—rooftop solar, battery energy storage, electric vehicles and distributed energy resources (DERs)—can already be found in millions of homes.”
UtilityDive.com (Ethan Howland): On June 28, Chevron received an unfavorable ruling by the US Supreme Court, which “creates legal and regulatory uncertainty for regulated utilities.” This presents disorder within the energy industry due to “the lack of clarity on future EPA mandates.”
“Planning for generation needs will be more challenging for regulated utilities and other power companies, due to the uncertainty of not knowing which cost-effective generation mix to supply.” This will force power providers to add more costly green power to the mix.
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…
