Battery storage continues to spread across the #WesternGrid. This 200MW/800 MWh project for utility Puget Sound Energy goes live in 2026. Washington is just getting started with batteries - 4MW of capacity today - 2,000 MW over the next three years. #energysky pv-magazine-usa.com/2025/12/04/8...

Massive new solar project goes live in Utah - 685 MW. More good news for the #WesternGrid. Interestingly, this project is not listed in any of the EIA tables. Seems like a pretty big miss. #energysky www.heraldextra.com/news/2025/no...

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

The latest CAISO Key Statistics report is available for October 2025. Plenty of useful factoids within... Here is one - almost 15 GW of utility-scale batteries on the CAISO grid. www.caiso.com/documents/ke...

Good news for US Battery Storage. Peak Energy is based in California and Colorado. It will be interesting to see how quickly sodium-ion storage scales. #energysky

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. #energysky pv-magazine-usa.com/2025/11/04/c...

Great to see the positive effects of renewables on the local level in rural America. An article worth reading.

Battery storage capacity continues to grow steadily on the CAISO grid. Currently nearing 15GW. As a reference - peak demand for CAISO was about 43GW this year. Source: www.caiso.com/documents/ke... (Sep 2025 Key Statistics) @californiaiso.bsky.social @calenergy.bsky.social #energysky

More batteries/solar in California are also helping to make the entire #WesternGrid more resilient. #energysky

This recent press release ticks all the boxes. - New 50MW/200 MWh battery in Arizona - Behind the meter! - Helping to power a new electric arc furnace at a Nucor steel plant Within five years, we are gonna see batteries everywhere. #WesternGrid #energysky ir.ameresco.com/news-events/...

More good news for the #WesternGrid #energysky

Potentially 100 GW of flexible demand... Even 20GW would be huge. 💡🔌 electrek.co/2025/10/01/h...

This may be true for the US, but the Western US continues to lower its fossil fuel usage at a steady pace. The estimate for 2025 is based on the data reported thru July. #energysky

I'm sure @dustinmulvaney.bsky.social is all over this, but just in case. @mariagallucci.bsky.social tells us "putting panels over 8K miles of federally owned canals and aqueducts could generate over 25 GW of renewable energy — enough to power nearly 20M homes" 🔌💡 www.canarymedia.com/articles/sol...

CAISO—@californiaiso.bsky.social is out with its latest Key Statistics report, this one for August 2025. Plenty of interesting info in this report - worth the read. www.caiso.com/documents/ke... Below is a sample showing that total battery storage has now passed 14GW.

Question for #energysky folks: Does anyone maintain a database/listing of actual proposed datacenters in the US(or other large loads)?

Yesterday was the highest peak demand so far in 2025 on @californiaiso.bsky.social - 43,735 MW at 6:00 PM. Relatively easy to handle versus a few years ago due to the increase in Battery Storage. Still, too much gas is being used to meet peak... more firm sources needed. #energysky

Love seeing innovative ideas like this...

More wind generation for Seattle utility Puget Sound to help replace imported coal generation from the Colstrip power plant in Montana. - 248 MW Beaver Creek Wind is now operational #WesternGrid 🔌💡 www.pse.com/en/press-rel...

California grid operator - CAISO - @californiaiso.bsky.social has released its July Key Statistics report. Well worth the read. July was a mild month weather-wise in California, and the stats reflect this. www.caiso.com/documents/ke... Here is a sample of the data. #energysky

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. #WesternGrid #EnergySky

Caterpillar joins the #datacenter bandwagon. #WesternGrid

Here is a great BTM battery storage article... "A 535MW fleet of aggregated household battery storage systems, including Tesla Powerwalls, effectively reduced net load on the California grid in a recent test event." #energysky www.energy-storage.news/tesla-sunrun...

Awesome to see projects like re-using "old" batteries. #energysky www.canarymedia.com/articles/ene...

New record for solar on ERCOT grid yesterday - 29,318 MW. Source = www.gridstatus.io/records Insane acceleration in solar deployment over the last five years. Any bets on when solar hits 50GW on ERCOT? Over/Under for July 2028. We take the Under. @commercialsolarguy.com #energysky

There are still plenty of "no-brainer" projects like this across the US. www.solarpowerworldonline.com/2025/07/edpr...

Here is a good recap of recent progress on @californiaiso.bsky.social - CAISO grid - from its CEO Eliott Mainzer. One takeaway: "One clear sign of progress: grid operators have not issued a Flex Alert asking consumers to voluntarily conserve energy since Sept 2022." www.caiso.com/about/news/e...

Such a no-brainer.

Massive battery storage project in planning phases for California. The interesting aspect of this is the 8 hour duration. - 1,150 MW - 9,200 MWh #energysky www.energy.ca.gov/powerplant/b...)

Need to see a LOT more geothermal projects get started. #energysky www.blm.gov/announcement...

Love this model. Take recycled EV batteries and use them to help power data centers. #energysky www.redwoodmaterials.com/news/redwood...

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.

Did u know? "The International Renewable Energy Agency shared that in 2010, solar was 4 times as expensive as the lowest-cost fossil fuel. Today (9/26/24), generating electricity from solar is less than half as expensive as the lowest-cost fossil alternative." 🔌💡 pv-magazine-usa.com/2024/09/26/s...

China just surpasses 1 TW of solar - installed nearly 100 GW just last *month* 🔌💡 @jmijin.bsky.social War is evil.

🔌💡@xiaomiglobal.bsky.social has entered the race for solid state batteries! Their new patent describes a layered electrode structure that claims: 🔋77.8% cell-to-body volume efficiency 🔋Range > 1,200 km (~750 miles) 🔋Charging 800 km (~500 miles) in 10 minutes. #EVs #battchat 1/2

Keeping an eye on this... #energysky #datacenter www.sltrib.com/news/2025/06...

A remarkable week for renewable energy records across US grids. Thanks to @gridstatus.io for info Source: www.gridstatus.io/records New all-time highs for renewables on 4 regional grids ! #energysky

1) The records keep falling on the California grid @californiaiso.bsky.social . New renewables peak record - 29,040 MW at 3:10 PM on Thursday. Notes: - Demand at 3:10 pm was only 25,992 MW. - Two years ago, the record was only 23,457 MW Source: www.gridstatus.io/records/cais...

Had not heard of this company - Glasspoint - who have developed an "internal" solar thermal technology. They have 2.2 GW of industrial process heat under development. The project below will help replace some industrial coal in California. #energysky www.glasspoint.com/press-releas...

A new record for battery discharge on CAISO - @californiaiso.bsky.social - 10,895 MW on June 17, 2025 at 08:05 PM 10,000 MW is now the "standard" for peak daily discharge. In another year, batteries will discharge 10,000 MW across multiple hours. Source: www.gridstatus.io/records/cais...

Good to see wind and solar as the top 2 sources for electricity in the middle of a hot day in Texas. #energysky Source: www.gridstatus.io/live/ercot?d...

Massive increase - over 3,000 MW in renewables generation record for Texas(ERCOT) grid! This record has increased 15,000 MW in just two years. Crazy! #energysky Source: www.gridstatus.io/records/erco...

Big jump in renewable generation record for ERCOT yesterday. Renewable generation went over 43GW for the first time - hitting 43,208 MW - representing about 58% of total output. This record has increased by 13 GW in just three years! Source: www.gridstatus.io/records/erco... #energysky

Great read on an under-reported trend.
