Various states in the US have either adopted, or are in the process of adopting, IEEE 1547-2018, which leverages new capabilities of smart inverters. Smart inverters are a kind of “grid-following” inverters. Now there is growing interest in “grid-forming” inverters, Read more…
I just launched a new 8-week course called “Interconnection of Utility-Scale Solar PV to Distribution”. With the growth in Utility-Scale Solar PV strong, the need is increasing for knowledgeable people that understand the electrical considerations and challenges with interconnection. You Read more…
Last month, EIA published its US Battery Storage Market Trends. Notable that:1. In 2019, 83% of small-scale battery storage (< 1 MW), which totaled 402 MW in the US, was located in California2. Between 2021 and 2023, installed large-scale battery Read more…
Below is a preview video of a course I designed and developed for anyone that wants to learn 28 key components of a distribution system, through video, photos, diagrams, and discussion. It’s great for utility personnel, solar developers, clean energy Read more…
According to a new US DOE Issue Brief and an upcoming NREL analysis, “…to reach a largely decarbonizedgrid by 2035, solar deployment would need to accelerate to three to four times faster than its currentrate by 2030.” It goes on Read more…
The chart above illustrates one of the challenges that needs to be addressed in order for solar energy to help with meeting climate change mitigation goals. The chart was put together by the Solar Energy Industries Association, The Solar Foundation, Read more…
President Biden’s announcement yesterday on tightening pollution rules and setting a target that 50% of all new vehicle sales by 2030 be electric vehicles is needed to combat climate change. This thought-provoking chart from the International Energy Agency shows the Read more…
When I first started out in electric distribution over 30 years ago, one of the things that helped build my knowledge base quickly was the Power System Engineering Course. It was offered at my employer at the time (GE in Read more…
In a previous post, I explored how my son explored charging options before he bought his new Tesla 3. For folks whose interest is in distribution system planning and engineering, there are a number of concerns related to Electric Vehicle Read more…
A couple of months ago, my son Andrew got his new Tesla. Model 3, in a gorgeous shade of blue. He got the standard package, which in my old-school book is anything but standard. Glass roof. Nothing on the dashboard Read more…
