copperhome.com, formerly known as Channing Street Copper Company. Impulse makes a cooktop that is embedded in a countertop, whereas Copper makes a standalone range (induction stove + resistance convection oven).
One way to do this is to embed the battery in a high-electricity-consumption appliance - there are at least 2 companies doing this with induction stoves. Plug and play - no permits.
Best food city in the country according to CN Traveler this year: www.cntraveler.com/gallery/best...
CEC MIDAS might have the Net Billing Tariff Rates now - I could check with them if it's useful. midasapi.energy.ca.gov
I made this web app last year when the rates were getting finalized. There isn't an API for live streaming rates though. osesmo.shinyapps.io/NBT_ECR_Data...
After I make a pivot table, I usually copy-paste its values into a new table next to it that I can clean up and take a screenshot of to share with others. Seems like sorting could be one of those cleanup steps.
Heard today from a former Enel coworker now at a different charging company that's looking at migrating JuiceBox customers over to their app, including migrating utility programs. Will know more soon.
The idea of leveraging the thermal mass of existing brick walls in buildings as thermal storage/demand flexibility was definitely a 🤯 moment while listening. Would be interested to know what the technical potential is - seems like it would be huge.
What if the Excel file was put on a thumb drive, which was then bolted to a concrete pad?
Know of any examples that show how to do this in Pyomo/Linopy? I just took a quick look at the GenX GitHub, but it looks like JuMP has its own unique syntax and I haven't programmed in julia before. github.com/GenXProject/...
Here's the current code that uses cvxopt: github.com/RyanCMann/OS...
I first learned how to do optimization in MATLAB, so I'm used to manually creating the A matrices and b/c vectors when setting up LPs, & can't figure out how to set up multi-timestep energy-modeling problems using packages like Pyomo/Linopy where equations are written out algebraically.
Great news! I'd love to switch my own (very small-scale) behind-the-meter open-source energy storage model over from cvxopt to highsopt as a way of testing it out, but the documentation seems pretty sparse. Is there a support community?
There's a "GHG stonks and flows" joke here somewhere. www.cmu.edu/gelfand/lgc-...
Yes - eyeballing from the chart, looks like there's about 5 GW of batteries and 5 GW of hydro now, & another 5 GW would mean that the gas would no longer be doing the duck-curve ramp on a day like this.
Did some toy modeling of this scenario for a college paper: www.researchgate.net/publication/...
The parts of the U.S. that are still fully vertically integrated seem to generally be behind the rest of the country on decarbonization. Their generation investment decisions also seem to be less transparent, harder to predict, and harder to shape through policymaking.
"If you haven't already seen some of those wild demonstrations where 10 kW of boost power brings a pot of water to boil in seconds, well - look those up. They're pretty impressive" - Alec sending out the @damico.bsky.social Bat-Signal. www.youtube.com/watch?v=Ydaw...
I like to think of renewables as having weather-dependent nameplate/max capacity, rather than weather-dependent output. As you point out, the capacity of thermal power plants is also weather-dependent (ex. higher temps = lower efficiency), although grid planning doesn't fully take this into account.
Or maybe not the valley itself, but some of the outlying areas.
It was interesting to hear VP Harris mention unprompted that she's a "space geek" and has had the chance to talk with astronauts about viewing Earth. Wonder what that means for a certain AZ Senator's VP chances . . . static1.squarespace.com/static/5f7d4...
Thanks for the reminder to re-listen to that episode of A Matter of Degrees: www.degreespod.com/episodes/sea...
Great episode, and an interesting listen after last week's episodes of @volts.wtf and Catalyst about shipping that mostly wrote off battery electric propulsion in favor of liquid fuels. Yet another "hard to abate" sector that turns out to be electrifiable - time for another H2 Ladder update.
There might be a way to enroll in the SCE/TeMix Phase II pilot: www.dret-ca.com/dynamic-rate...
Did you create an automation to do this?
The only product I'm aware of that does something similar is JuiceNet Green (on Enel X Way JuiceBox chargers) using marginal emissions data from WattTime.
My understanding is that only generators see nodal prices, LSEs buy @ DLAP.
... cost & therefore their marginal cost is lower than fossil fuels. Also, US reactor designs can't really ramp up and down, so they have to be run at constant output to serve "baseload". See the Figure 2 graph, which I found on PJM's website: www.researchgate.net/publication/...
Also, this is really nitpicky, but the description of nuclear as being @ the top of the bid stack ("tends to be the most expensive") was incorrect. A plant like Vogtle has a very high levelized $/kWh cost, but nuclear plants in competitive wholesale markets bid in a low price, because their fuel ...
... elements (super-wonky and region-specific ones like Reliability Must Run contracts, or methods of deeming qualifying generation capacity in capacity markets, or even utility cost-of-service regulation) that are keeping fossil power plants online and/or undercompensating renewables.
Interesting listen! Haven't read the book, but it seems strange that so much focus was on spot markets. The wild price variations in space & time are certainly unusual compared to other commodities but largely a "feature, not a bug" incentivizing things like storage, and it's other market-design ...
Unlike even some of the DER Task Force podcast guests, Lorenzo recognizes that decentralizing grid resources goes hand-in-hand with decentralizing ownership, planning, and control as well. Feels like a version of en.wikipedia.org/wiki/Conway%...
Your 2018 Vox piece with him is still probably my favorite and most-shared-with-others (and I've been reading/listening since the Grist days). Just shared this podcast on the DER Task Force Slack.
Seeing that ad a lot on the New York Times site recently. Hard to believe propane is the cheapest option for space/water heating - I've only heard of propane appliances in places without natural gas distribution.
