Solarpunk

I saw some context for this, and the short of it is that headline writers want you to hate click on articles.

What the article is actually about is that there's tons of solar panels now but not enough infrastructure to effectively limit/store/use the power at peak production, and the extra energy in the grid can cause damage. Damage to the extent of people being without power for months.

California had a tax incentive program for solar panels, but not batteries, and because batteries are expensive, they're in a situation now where so many people put panels on their houses but no batteries to store excess power that they can't store the power when it surpasses demand, so the state is literally paying companies to run their industrial stoves and stuff just to burn off the excess power to keep the grid from being destroyed.

To be fair, having a mismatch between when energy is available and when it is needed is going to be a problem under any economic system, since it's a fundamental inefficiency that must be worked around with additional effort and resources

Both of the statements in that screenshot are just so inane.

Frequency has to be maintained on the grid. It’s the sole place where we have to match production and consumption EXACTLY. If there’s no battery or pumped storage storage available to store excess energy, the grid operators have to issue charges to the producers, in line with their contracts, to stop them dumping more onto the grid (increasing the frequency). The producers then start paying others to absorb this energy, often on the interconnectors.

It’s a marketplace that works (but is under HEAVY strain because there’s so much intermittent production coming online). When was the last time you had a device burning out because the frequency was too high?

Turning the electricity grid into some kind of allegory about post-scarcity and the ills of capitalism (when in fact it’s a free market that keeps the grid operating well) is just “I is very smart” from some kid sitting in mom and dads basement.

If the excess energy cannot be stored, it should be used for something energy intensive like desalination or carbon capture.

My favorite solution for storage of excess power is closed loop pumped hydro. Two bodies of water of different elevations are connected by a generator/pump. When there is too much power, the pump moves the water to the higher lake. When the power is needed, the water flows through the generator to the lower lake.

I get the sentiment in here, but the poster is missing an important point: there is a reason some group of lunatics (called the TSO or Transport System Operator or in some cases other power producers) are willing to pay for people to consume electricity when there is too much of it; They are not doing it for the sake of being lunatics, the electrical system cannot handle over or underproduction. Perfectly balanced (as all things should be) is the only way the grid can exist.

The production capacity in the grid needs to be as big as peak demand. The challenge we face with most renewables is that their production is fickly. For a true solarpunk future, the demand side needs to be flexible and there need to be energy storages to balance the production (and still, in cold and dark environments other solutions are needed).

In off-grid, local usages we usually see this happen naturally. We conserve power on cloudy low-wind days to make sure we have enough to run during the night (demand side flexibility) and almost everyone has a suitably sized battery to last the night. The price variability is one (flawed) mechanism to make this happen on a grid or bidding zone level.

This is a real problem but you can only have so many words in a tweet. Note that the price isn't zero but instead negative. It means there is literally too much power in the grid and it would need to be used. If a grid has too much power then it is bad. It can damage it. There are things we can build that essentially amount to batteries (or natural variants like a dam) that get charged during times of higher supply than demand and discharged during times of higher demand than supply.

Scarcity is artifically created in the modern age

Unfettered capitalism will be the end of us.

We need natural batteries like solar power lifting water from a lake into a reservoir so that when we need that energy and the sun isn't making it, released water does

Am I the only one noticing a lot of conservative economic priests in here? Is this normal?

No, it's not. It's a practical problem, not an economic one, but leave it to the tankies here to take it as an opportunity to show how many slogans they have learned.

Nikola Tesla was a radical anarchist then, I guess? :-P

Prices going negative is Capitalism's solution actually. Gives the price incentive for folks to charge their cars when prices go negative, or whatever.
