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.

California has a huge solar power problem. A fix is coming. The state's glut of solar power is about to become far, far easier to sell.

As DC digs in on policies fueling inflation & the climate crisis, CA is expanding how it collaborates with the West to increase access to cheaper clean energy. #westerngrid

This is a huge deal for #WesternGrid. This project will provide clean generation during non-solar hours.

ContourGlobal secures $350 million, its first solar project financing in the U.S. The funds support ContourGlobal’s 324 MW solar project in development in Colorado.

The #WesternGrid continues to get cleaner. The contribution this time is from the 324 MW Black Hollow Sun project in Colorado. The first phase, 185 MW, is already live, and the second phase, 139 MW, will be completed by the end of 2026.

Battery storage is booming in the Western US - even outside of California.

- 7,200 MW of storage as of June 2025
- could have another 3,000 MW by year-end.

Need to keep up this pace if coal is to close out West.

California Sets Sights on Streamlining Western Energy Market with Senate Bill 540 California is pushing forward with Senate Bill 540, a measure aimed at integrating its energy grid more seamlessly into the Western region's unified energy market. The bill seeks to streamline regulatory obstacles and enhance renewable energy collaboration in order to better balance power supply and demand, particularly with intermittent sources like wind and solar. By streamlining electricity transactions and increasing cooperation between utilities, California hopes to reduce inefficiencies and costs associated with its current fragmented system, which has already saved $7 billion over ten years through the Western Energy Imbalance Market.

Although in California SMUD - Sacramento Municipal - is outside of CAISO grid.

Great to see other parts #WesternGrid adding more storage. Hope to eventually see Rest of Western Grid with 2x the batttery storage of CAISO.

Battery storage is beginning to play an important role on the Southwest United States grid.

The ‘clean transition tariff’ won approval in Nevada. What’s next for Fervo? The geothermal company has a high-profile partnership with Google — and now has more data center demand than it knows what to do with.

Below is a very bullish article on geothermal in general and Fervo Energy in particular.

Looking forward to seeing a 1GW geothermal site on the #WesternGrid.

Gonna cover two questions.
- What progress has been made?
- What needs to be done to eliminate coal?

First, let's take a look at progress in decreasing coal generation.

- a drop of 130 TWh in coal generation since 2010
- 88 TWh of coal gen remaining
