Podcast Episode 100! What Brings Us Together

There are so many reasons to go solar and so many people with different opinions of why. Rather than arguing about why everyone needs to go solar, let's get together, as humans and install more solar and storage! Forgetting about our differences and working together on this project, is what will have the greatest effect. Instead of letting politics divide us, let's come together and

 

Here are some of the reasons that people go solar:

 

Saving money

Climate change

Green jobs

Oil wars

Giving our money to dictators

Energy independence

Neat technology

Backup power

Living off grid

Disconnecting from utilities

Prepping for the worst

Going green

Clean air

Good health

 

Personally, I like going solar for all of these reasons, but just because someone else is politically against some of these things, does not mean that we should alienate them from this great family of an industry!

 

This podcast is being released during my RE+ NEC workshop with Bill Brooks. I have taught this workshop at every RE+/SPI since 2012! Celebrate! Good times!

NEC Article 690 Part IV Wiring Methods & Materials from PV and the NEC 3rd Edition book by Sean White and Bill Brooks

Buy this book here:

https://www.amazon.com/PV-NEC-Sean-White/dp/100318099X

 

This long podcast is a reading of chapter 5 of the book, which covers NEC Article 690 Part IV of the 2023 NEC.

 

Every 3 years when the NEC comes out, it is a tradition for me to read and post a poetry reading of Article 690 Photovoltaic Systems. I have already posted parts I through III on this podcast, which you can go back and listen to.

 

Sean White and Bill Brooks will be presenting this material at RE+ in Vegas in September and at Intersolar in San Diego in January, so be sure to check out their live workshops in person. The 2023 NEC material will be posted on HeatSpring soon, as it is in production now, so keep an eye out!

 

The NEC can be dry, and we do our best to make it exciting!!

 

Don't get shocked, unless you are shocked about how we present ourselves!!

World’s Largest Battery Energy Storage Systems (BESS)

There are many ways to define the largest BESS and since the industry is growing so excitingly fast, it is difficult to explain exactly which is the largest.

 

We are going to talk about 7 big ones here:

 

1. Vistra: Moss Landing California US 2021 400MW/1600MWh

2. Crimson Storage: Blythe California US 2022 350MW/1400MWh

3. Manatee: Florida US 2021 (largest with PV) 409MW/900MWh

4. Victorian Big Battery: NSW Australia 2021 300MW/450MWh

5. McCoy Solar / BESS: Blythe California US 2021 230MW/920MWh

6. Elkhorn Battery: Moss Landing California US 2022 182.5MW/730MWh

 

Number 7 on this list is not the 7th largest battery today, but gets mentioned because it was once the largest in the world, first to reach 100MW way back in 2017 and was made because of a crazy social media bet.

 

If you are listening to this podcast in 10 years, it will be funny to compare these largest systems to the new largest BESSs in the world. What will they be? 100GWhs? Crazy to imagine this kind of growth!!

Lithium-Ion Battery Chemistries

Sean is recording this podcast from Australia where he is about to teach a utility-scale battery energy storage systems (BESS) course for CPD International. This is some of the material that will be included in the course.

 

In this podcast, we will go over different battery chemistries, focusing on the three main types of lithium-ion batteries used these days, which include:

 

1. Lithium Iron Phosphate (aka LFP or LiFePo or LiFePo4)

2. Lithium Nickel Manganese Cobalt Oxide (aka NMC or NCM)

3. Lithium Nickel Cobalt Aluminum Oxide (aka NCA)

 

We will talk about the availability of these elements on Earth, the toxicity of them, we will compare and contrast to lead-acid and nickel iron batteries and we will take a dive into the controversial Cobalt, which is said to have a supply chain where child labor is often used in the Congo. Australia does lithium and cobalt mining, which is part of the solution, however the use of cobalt free lithium-ion batteries, which means LFP seems to be the solution, however the batteries with cobalt do have a higher specific energy (not to be confused with energy density).

 

Specific energy = energy per weight (most important for EVs)

Energy density = energy per volume
