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. #energysky www.energy-storage.news/berkshire-ha...

February is usually the start of the "record season" in the electricity market. Kick it off with a new record for solar in ERCOT... should be passing 30,000 MW shortly. Thanks to @gridstatus.io for info. #energysky Source: www.gridstatus.io/records/erco...

US battery storage is exploding... up more than 15,000MW (= 15GW) this last year. Expect more than 20 GW to be added in 2026. #energysky

From the latest ERCOT fact sheet - www.ercot.com/files/docs/2... Some good nuggets....

California grid operator - @caiso.com is out with its Key Statistics report for December. Plenty of interesting factoids for those interested. www.caiso.com/documents/ke... Here is one : Installed BESS ended the year at almost 16GW. This is an increase from about 11.5 GW in 2024. #energysky

‘By 2050, sodium-ion batteries with fast learning rates could deliver storage at 11–14 €/MWh – cheaper than lithium-ion at 16–22 €/MWh…stationary battery demand reported to date – ranging from 67.9 to 106.5 TWh by 2050…feature higher energy-to-power ratios (6–7 h)’

No-brainer: if you have a retired fossil plant with an interconnection - add battery storage. #energysky news.duke-energy.com/releases/duk...

Good to see the New England grid expanding its portfolio...

1) Battery storage on #CAISO is now being regularly charged at over 10 GW. Source: www.caiso.com/todays-outlo... #energysky

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. #energysky

Here is something every state should have/look into - EV charging in DMV lots. It also makes sense to add solar in these parking lots. No-brainer. #energysky electrek.co/2026/01/02/c...

Just throwing this out there... Oil price over the past year. #energysky

From ERCOT Monthly November 2025 www.ercot.com/files/docs/2... Note: This monthly update provides a variety of grid statistics. One example:

1/3 I thought I'd stay close to home with my posts today. My Assemblymember @dawnaddis.bsky.social is one of the 18 legislators. And my provider, PG&E is indeed holding up my interconnection. Go get 'em Dawn! 🔌💡 pv-magazine-usa.com/2025/12/01/c...

Hey, a TeraWatt here, a TeraWatt there, and before you know it...

Some good info on battery safety in this thread.

A disappointing announcement from Puget Sound Energy - 700 MW of gas till 2045. Seems like a rushed last-minute deal. Hopefully, they will also install at least 400 MW of battery storage at this location. @nwenergy.bsky.social @olympiajoe.bsky.social washingtonstatestandard.com/2025/12/09/w...

The good news for batteries keeps coming.... Latest report on battery prices from Bloomberg: about.bnef.com/insights/cle... My favorite quote: "Battery pack prices for stationary storage dropped to $70/kWh in 2025, 45% lower than in 2024." #energysky

Huge news... This tech is already in production and being used in smartphones. Next up, EVs and energy storage. #energysky

Awesome!

Microsoft combines two locations to build a massive AI system. This has significant implications for energy infrastructure. In this case, they joined Atlanta with Wisconsin. news.microsoft.com/source/featu... #energysky #datacenter

The September Electric Power Monthly is out from EIA. www.eia.gov/electricity/... Looking at the Capacity added to the US grid so far in 2025, we can see that almost 90% comes from Solar and Wind. #energysky

Is anyone tracking the amount of factory capacity available for batteries in the US? This Toyota plant has a capacity of 30 GWh. Tesla has 40 GWh of capacity in CA and 10 GWh in NV, with another 50 GWh under construction in TX. What else? @michael-thomas.bsky.social @jrfhanger.bsky.social

A recent EIA article said: "Although natural gas generation still provides more electricity than any other source in California..." This is incorrect. If you include rooftop generation, solar is now the largest source. Q1-Q3 2025 All Solar = 73 TWh Gas = 54 TWh www.eia.gov/todayinenerg...

2/2 From my old neighborhood. "The microgrid and pending EV bus delivery bring the VTA one step closer to satisfying California’s mandate that all public transit agencies transition to 100% zero-emission bus fleets by 2040." 🔌💡 www.microgridknowledge.com/microgrids/c...

Wow! Indiana is definitely a spot to keep an eye on... when it comes to grid demand growth. Amazon announces another 2.4 GW of data center capacity today. This is in addition to the current Project Rainer in Northern Indiana, which is rated at 2.2 GW. 💡🔌 www.aboutamazon.com/news/company...

Great report from @robgramlichdc.bsky.social and folks at Grid Strategies on a possible path for data center demand over the next five years. This is really tough to predict, but good to have a "stake in the ground" which can be used going forward. #energysky

Thanks Nate.

@nateforutah.bsky.social - I assume you are already familiar with this... Do you have any other feedback/comments?

2/3 Flying home Friday I saw many naked roofs. With electricity costs outpacing inflation I wonder why we don't see more of these. Kudos to United Natural Foods "the 6.7-megawatt solar array generates enough electricity to power roughly 1,500 homes annually." 🔌💡 www.utilitydive.com/news/unfi-co...

Yeah, you need to be at like $20/MWh in the US to compete with gas for heat

This table needs updating. But might be still useful. Enertime has a new name now. Also @janrosenow.bsky.social has started making a map of companies involved in industrial heat tech.

Also energy storage (Includes Rondo)

I think this is really important for the long run. Right now though, companies are willing to pay more than fossil cost for green power. Reputation is valuable. In the medium term, these local-solar heat battery solutions are a form of hedging. But mostly I think companies are trying it out.

Love this concept ... Redwood Material has built a "black box" to connect a hodgepodge of used batteries into a cheaper BESS. Every year, the supply of used batteries will grow. Ten years from now, a big chunk of BESS projects across the US will be developed with second-life batteries. 💡🔌

Interesting to see that solar now shows up in second place for hourly fuel share across the US. Currently, only a few hours a week, but let's see how this changes over the coming years. #energysky

Is this one of the most under-reported stories out there? This product looks like it is the answer to electrifying industrial heat. Am I missing something?

What a great project! The #WesternGrid keeps getting cleaner.

You gotta love unintended consequences...

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

About 50-60 GWh of battery storage was added in the US over the last 18 months. The total is now about 100 GWh. It would be nice to see this grow to 500 GWh by 2030.

Let's see more of this...

Gonna need a LOT of new transformers...

I highly recommend this article on solar growth in Africa... Love to see this. #energysky ember-energy.org/latest-insig...

An interesting concept from @simonmahan.bsky.social www.pv-magazine.com/2025/08/18/d... #energysky

I somehow missed this thread a few weeks ago. Great concept - "Enhanced Geothermal Data Center Cluster". Looking forward to 10 GW of development in Utah by 2035! Next up - expansion to other Western States - especially California. Also @jackconness.bsky.social - good follow. #energysky

Love this example of learning curve - products getting better AND cheaper.

Not enough. The US needs to get to 100 GW of utility-scale per year. At least. Note: Here are recent yearly solar additions. 2022: ~ 11 GW 2023: ~ 19 GW 2024: ~ 31 GW @cjhandmer.bsky.social
