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

Show me the batteries !

BTM storage is starting to become significant... #energysky www.utilitydive.com/news/sunrun-...

Good morning with good news: Poland's RE passed coal for the first time in June, generating 44.1% of Poland’s electricity, with coal falling to 43.7% Coal fell to 46.2% in Q2 2025 from 56.4% in Q2 2024. Wind & solar surged to ~39% in 6/2025 from 28% in 6/2024! www.ft.com/content/ae92... #energysky

One of the most under-reported stories out there. The US auto industry is being left far behind. #energysky

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

BNEF takes the under on US data center load growth (43.5GW of new capacity by 2035) due to "real-world constraints like interconnection delays and build timelines" - underscoring market opportunity for faster connection via flexibility. 🔌💡

Interesting things are happening in US coal markets right now. Overall, production is up slightly in the first quarter while employment is still trending downward: www.spglobal.com/market-intel... 🔌💡

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

CAISO set a new Renewables peak generation record yesterday at 28,242 MW at 1:05 PM. The load at this time was only 21 GW, so this record would not have been possible without recent growth in battery capacity. Source: www.gridstatus.io/records/cais... #energysky @californiaiso.bsky.social

Battery discharge over 10GW on CAISO. Nice. It will be interesting to see if future capacity continues to move towards peak and/or spreads out the discharge to more than four hours.
