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

<p>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.</p>

<p>“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.</p>

<p>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.</p>

<p>>The overprovisioning of solar is going to create so much cheap surplus energy during summer and during the day<p>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!<p>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.<p>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.</p>

<p>I think the valuation is based on potential for growth.<p>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.<p>Tesla has learned how to do everything in a decade and has exceeded traditional automakers in some areas and has nothing to lose.<p>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.</p>

<p>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.
