From NPR News – Due to the arctic blast and frigid temperatures well below zero degrees, many electric vehicles (EV’s) were sadly affected. Since the frigid temperatures in the northern part of the U.S. reached levels below the EV’s normal operating temperature ranges for their batteries, the vehicles could not be re-charged or maintain a constant charge. This presented major obstacles for many Tesla owners in Chicago along with longer than expected lines for Supercharger stations.
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.
Tesla has announced they will recall over 2-million electric vehicles that affect multiple Tesla models, like models S, X, Y, 3, and semi-trucks. The recall is due to its “full self-driving beta” software causing some life-threatening and unsafe conditions.
The recalls will include a free software update to patch any software bugs in the coding to improve driver safety.
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:

The US Department of Energy (DOE) will deploy long-duration energy storage (LDES) projects for maintaining power delivery for “10 to 24 hours or longer to support a low-cost, reliable, carbon-free electric grid. Funded in part by President Biden’s Bipartisan Infrastructure Law, this funding opportunity will advance new renewable energy technologies, enhance the capabilities of customers and communities to integrate grid storage more effectively, increase grid resilience, and expand America’s global leadership in energy storage.
The Biden-Harris Administration, through the U.S. Department of Energy (DOE) has announced $350 million for these emerging” type projects.
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.”
