Rivian partners with Tesla co-founder's Redwood on energy storage Rivian is partnering with Redwood, founded by Tesla co-founder JB Straubel, to deploy 10 MWh of second-life battery storage at its Illinois plant.

What a great idea! Redwood Materials to deploy a "used battery" storage facility at Rivian vehicle factory.

Every large industrial facility should have some battery storage - and better yet, make it used batteries.

California's grid @caiso.com needs to complement its massive solar/storage capabilities with other sources, like wind and geothermal.

The wind from the SunZia project will displace more natural gas generation in California.

At the time, the 12.29GW of battery discharge represented 44% of total demand. Remarkable !

@caiso.com Battery discharge went over 12 GW for the first time last night! Just two years ago, the record was about 6GW.

Berkshire Hathaway Energy Montana energises 150MWh BESS Berkshire Hathaway Energy Montana has successfully energised its 75MW/150MWh Glacier Battery System project in Montana, US.

The first utility-scale battery storage system is live in Montana - 75 MW/150 MWh.

BHEM is also building a 120MW solar system, which should go live this year. More clean energy for the #WesternGrid

Huge potential for solar/storage in Montana.

3) Fossil fuel share continues to decline in ERCOT.

2015 = 76% ---------- 2025 = 54%

In the past year, almost all the decline was due to an increase in solar share.

#energysky

2) Note: Solar > Coal

This was the first year that solar beat coal on ERCOT for total generation.

1) ERCOT released its 2025 Demand and Energy report
www.ercot.com/files/docs/2...

Although overall demand increased by 26.2 TWh, fossil generation was flat, with an increase in coal mostly offset by a decrease in gas.

Most of the new demand was met by a solar increase of 19.6 TWh.
