Why did you stop using Victoria metrics and what are you using instead?

Vancouver development is in bad shape now thanks to these taxes and a glut of new supply that was built with financing not available to the average developer

Pre sales are dead. Some projects are in receivership. New Projects are not going ahead

I’ve done small systems less than 2 MW with 2-3 generators, a mix of hydro and diesel, and only distribution level voltages.

It seems like you would black start some plant using its backup diesel generator to power pumps and controls, probably synchronize at least two units at the plant, then pick up some part of the transmission system. Perhaps the capacitance of the grid is and issue when it is unloaded, so the trick is to make sure enough real and reactive capacity is online for each subsequent transmission or load step. Probably a lot of transmission steps come with a significant amount of load too - not just picking up unloaded transmission lines. Sounds really fun, banging all the governors and exciters with once in a decade load steps

Ah! Perhaps you are a member of the gigawatt club? Eligible for entry once you have accidentally tripped off 1000 MW of load or generation! No sweeping that under the table

Do you have first hand experience re-energizing an entire grid, section of the power system, or individual generators after an outage?

First responders would carry narcan or equivalent. I am sure it is readily available in areas where people are dying daily from overdoses.

How does residential solar increase grid stability?

The “Stability” of a power system would relate to the ability to withstand changes in load conditions. I don’t see how residential solar contributes positively to that.

My recollection is it also dimmed the areas of the Speedo that were far from the current speed

Maybe the demographics of HN are such that a bunch of people just had kids.

A downside to these schemes is that the stability of the electric system now also depends on large communication networks and some computer solving some algorithm. I can imagine the outages. I prefer my power outages to be caused by good old fashioned weather rather than Hadoop kubernetes cluster operator eventually consistent race error.

“Nodal pricing” exists in several markets but isn’t often used. One example is in Ontario the nodal price in Thunder Bay was always very low since industry there had collapsed but there were still three coal fired power plants. They could bid a low price so it would be accepted, and due to low local demand the supply and demand solved for a low price in Thunder Bay, but due to transmission constraints all of the bidders could not generate what they bid, so they would have to be constrained off. I can’t recall if they got a payment for the power they weren’t able to generate.

I think it is different than other commodities since it is very expensive to store electricity. A diesel powered generator and tank full of diesel is probably the best option.

The overprovisioning of solar is going to create so much cheap surplus energy during summer and during the day

I associated this cheap power during summer days as when prices approach zero or even go negative. Power you have to pay to have somebody take is worse than worthless!

So some days the power is cheap but it still costs a lot for transformers, grid interconnections, power lines, battery systems if you want power on a cloudy day, so any solar farm that gets built has to cover financing of those costs, which means power is also expensive some of the time.

We can’t both have power so cheap we can dream up ways to use it when it is practically free and also be able to pay for it to be built and maintained.

Who will pay to build these solar farms whose output is worthless?

Is there any substitute for chrome cast audio? I love being able to play in sync audio to the group of receivers I choose throughout the property, using any amplifier. I’m not even using the digital optical input and I love them

TIL

The fields decrease in strength with distance, the square of distance for electric fields.

Your cellphone transmits at 1 watt and you put that at a distance of zero from your brain and reproductive organs.

If you are worrying about power lines you should worry about cell phones too

TIL VLC supports chromecast from the GUI!

I think the valuation is based on potential for growth.

People expect Tesla to grow by doing new things that other companies don’t have the ability to do, either because they have a cash cow they don’t want to disrupt, they don’t appreciate the value software can bring to automotive with some more love than it has been getting, they don’t have the people and culture to take risks and everyone is happy with small tweaks to existing designs, they don’t know how to go back to the drawing board and make a new car and new production line from first principles.

Tesla has learned how to do everything in a decade and has exceeded traditional automakers in some areas and has nothing to lose.

I don’t care about Elon, I have never owned Tesla stock, but I surely admire his ability to execute, and I think that is part of the reason the market assigns such a high multiple Tesla - they are going to be at the vanguard of any developments in the electric terrestrial transportation space.

There are probably a dozen articles on the issues in that pique news paper spanning a decade. Lots of finger pointing between the parties responsible for the design, installation and maintenance. The Vocal group of owners got bailed out by the local government at one point but it didn’t resolve the ongoing issues.

Not to say the technology is hopeless, just in this instance it wasn’t done properly so maybe it isn’t as easy as people think.

This was tried using money for 2010 olympics in Whistler BC as the athlete accommodation was sold as subsidized housing to local workers after the olympics. The geothermal district heating project had many ongoing issues with repair costs being borne collectively by the new owners. Some saved $150/mo by removing it and switching to electric [0]

I’ve filed a few returns in new zealand and it seemed pretty simple, I was a simple case though

I used to use qiqqa for exactly what you describe but I think zotero has won this space

Qiqqa used to be my choice in this space but the devs have moved on

How many cycles is the battery good for? Do you want to use up half of them running your house loads to save $2?

I designed control panel modifications and programmed an upgrade to a hospital diesel generation system so they could transfer from diesel back to utility without an outage, and have planned transfer of load to diesel without turning the lights out.

We had three windows at 1 am where any new critical patients would be diverted to a different hospital. The first we used for major maintenance to the breakers in the switchgear, the second we used for modifications to the bus work, and the last outage was to test the operation of the new control system.

They do a transfer to diesel every month and the whole hospital is aware of it in case it results in a blackout.

I’m running three of them, they work perfectly with audio in sync outdoors and different rooms indoors.

I wish there was some equivalent still available.

The physical dynamics of the processes are the interesting parts for me. Ladder is good for representing Boolean logic but the paradigm has been stretched too far beyond its area of strength.

What platform allows use of git?

My process lends itself to function block programming so generating useful diffs requires quite a lot of effort.

Because they have signed 40 year contracts so that the people that built the power plant could get financing
