I've been working on a project to learn about solar + batteries co-located with loads. This post discusses optimization for consistent year-round supply. Let me know what you think! I'm new to clean energy so still learning how solar design is done. 🔌💡 Link: clindsey.substack.com/p/solar-and-...

How does the interconnection process change for generators vs. loads? In terms of cost, duration, complexity, etc. #energysky

Does the lead time for grid interconnection change with the capacity of the new connection? If I wanted to connected 1 kW, the grid would hardly notice. However connecting 1 GW would be a different story. Are there thresholds where the interconnection time becomes substantially longer? 🔌💡

Interesting and honest discussion of what went wrong at Northvolt. Trying to do too much at once, and not focused on being competitive in a global market. 🔌💡 podcasts.apple.com/us/podcast/r...

PG&E submitted a request to the CPUC to increase rates so they can modernize their billing system. Proposed cost for the system is $761M, all to be paid by our rate increase. If you are interested, I did a first pass at the issue at pelegri.substack.com/p/7613-milli... #energysky

$761.3 million for a Billing System?

Would you approve this proposal from PG&E?

Can anyone explain how variable production will support firm consumption? Take hydrogen for example. The plan is to utilize intermittent renewable power when it's cheap, but the processes that use H2 run 24/7/365. Is the only answer "lots and lots of storage"? #energysky

Is firm energy generation valued the same as variable? Or are prices bifurcated between firm and variable? To clarify, I mean the prices consumers are willing to pay (e.g. PPA's), NOT cost (e.g. LCOE). Is there any data on this?🔌💡

Today’s hot electrical take is that 120/240v delta needs to make a comeback for businesses. Can charge electric cars at 240v (instead of 208 from 120/208 wye) and still run 3 phase 240 and single phase 120v things just fine.

Battery-electric trains are promising, with real-world trials paving way for inter-city passenger trains w/ all-electric range of 100-150 km (~60-90 miles), so big stretches of longer routes can avoid expensive overhead wires (eg tunnels, mountains). electrek.co/2024/11/08/u...

This seems like a bad idea and runs the risk of backfiring. Low carbon fuels aren’t economically competitive yet, but you’re making the consumer shoulder the cost. California Toughens Climate Fuel Rules Despite Possible Cost www.bloomberg.com/news/article...

California Toughens Climate Fuel Rules Despite Possible Cost

California regulators tightened requirements for the carbon intensity of fuels sold in the state, despite fears the move could add nearly 50 cents to the price of a gallon of gasoline.

MITEI article on DAC. Overall, DAC is still expensive and energy intensive. Makes one think if there should be a reevaluation of CCS implementation to maximize tonne of CO2 sequestered per $ spent. energy.mit.edu/news/technol...

Great example of collaborating with local groups on where to site renewable projects. “[This] never would have happened without the environmental and labor movement’s proactive efforts to build consensus around where offshore wind should happen”

“Andrew Dameron, general manager…said the project will also bring a number of benefits…it will bring in about $80,000 annually, to be used to fund the district’s low-income sewer service charge program…also increase recycled water quality and quantity by reducing evaporation”
