Quote: “”Renewables are nearly 30% of utility scale generating capacity. The latest capacity additions have brought solar’s share of total available installed utility-scale (i.e., >1 MW) generating capacity up to 8.25%, surpassing that of hydropower (7.88%). Wind is currently at 11.77%. Solar and wind combined now account for more than a fifth (20.02%) of the US’s

Good article a few months old. JHAT recently had this reconductoring topic. This article also describes the Heimdall Ball temperature monitoring. One thing that has not been talked about is the use of BESS – battery energy storage systems – to reduce the peak load on the transmission lines. That’s what they did in Australia

This link to the article is supposed to be free, and *not* behind a paywall. This well-researched article is a good article, with some statements that are disputable. One example is that they state that lithium batteries are flammable. The LFP cells now used in battery storage systems are low to not flammable. There are

It looks like this supercapacitor could quickly charge and discharge, thus reducing the cycles on the EV battery. https://www.livescience.com/technology/electronics/ev-batteries-could-last-much-longer-thanks-to-new-capacitor-with-19-times-power-density-that-scientists-created-by-mistake
Natron enters low volume production. The article says 70 Wh/kg, less than half of lithium. “”…advantages such as faster cycling, longer lifespan and safer, non-flammable end use have made sodium-ion an attractive alternative…”” https://newatlas.com/energy/natron-sodium-ion-battery-production-startt/
Quote: “”The IEA’s “Batteries and Secure Energy Transitions” report finds that capital costs for battery storage systems are projected to fall by up to 40 percent by 2030. This significant cost reduction will make combining solar and wind with battery storage more affordable than building new coal or gas power plants in many parts of

Short article about deployment of enhancements such as high performance conductors. Quote: “”…and up to $331 million from the Bipartisan Infrastructure Law for a new 285-mile transmission line that will carry more than 2 gigawatts (GW) of transmission capacity from Idaho to Nevada.”” The US just came up with a plan to upgrade 100k miles

Wow! It just clips onto the HV cable and recharges while it’s hanging there. Presumably the drone has an inductive pickup coil that’s up against the conductor that’s carrying hundreds of amps. I bet Joe Tegtmeyer would like to have one of these! https://www.facebook.com/interestingengineering/videos/1123581112297321/?mibextid=NnVzG8 https://www.facebook.com/reel/415716777728231?mibextid=9drbnH&s=yWDuG2&fs=e
The transmission pylons are a few million dollars a mile, and the undersea cables are even more expensive. And the undersea cables are more difficult to maintain, as is anything in a marine environment. So the cheap SOBs in the utilities typically choose the lower cost towers. As for the US West Coast, rooftop solar
