So, negative energy prices would mean ... higher energy prices. That's why the grid should be allowed to buy from whomever it wishes, and would probably favour whoever can provide a stable baseload; instead of being forced to prefer suppliers that tend to provide unpredictable slumps and spikes. | |

Maybe on this day Goldisthal Pumped Storage Station was able to buy electricity for negative money and then sell it later for positive money, win win! | |

| Jun 6, 2016 at 7:11 | comment | added | John Dvorak | Why can't the power plant just build a giant laser and shoot excess energy into space? | |
| Jun 4, 2016 at 17:18 | comment | added | Fattie | This answer continues the confusion between "electricity" / "energy" language. Try to get a negative price on gasoline. | |
| Jun 3, 2016 at 13:49 | comment | added | Oddthinking♦ | Based on the comments, and the misleading wording in the claim, do you think it is worth explicitly mentioning who is "paying" these negative prices, and that it is NOT the consumer. | |
| Jun 3, 2016 at 7:14 | comment | added | Criticizing Israel not allowed | @AmaniKilumanga They probably do do that - or the business has a live feed of power prices and does it themselves. I know really energy-intensive businesses (like aluminium smelters) will lower production when power prices rise and pick it back up when they fall - this would just be a continuation of that. | |
| Jun 3, 2016 at 7:11 | comment | added | Taemyr | @amanikilumanga That would not work. Because the energy intensive business needs a contract for energy that spans more than a day. | |
| Jun 3, 2016 at 7:10 | comment | added | Criticizing Israel not allowed | @DanHenderson It means you power company will pay for the power their system supplied. Whether they charge you for it is up to them. | |
| Jun 3, 2016 at 0:40 | comment | added | Amani Kilumanga | "the power plant operator may choose to pay for power to be consumed" Say what? Do they just call up a really energy intensive business, like a factory and ask if they would like their ventilation systems powered? | |
| Jun 2, 2016 at 22:22 | comment | added | Andy | Was this even solely attributable to renewables? This article suggests that a lot of renewables and COAL plants came online in 2014, and I imagine its much harder to shut down a coal plant than wind: bloomberg.com/news/articles/2014-06-26/… | |
| Jun 2, 2016 at 22:16 | comment | added | Dan Henderson | If the price is negative, and I have a solar roof, does that mean that the power company will charge me for supplying power into their system at that time? | |
| Jun 2, 2016 at 20:14 | comment | added | Criticizing Israel not allowed | So how long until we see businesses that exist only to operate resistor banks? | |

| Jun 2, 2016 at 13:26 | comment | added | RedSonja | FYI I have a whole solar roof in Germany. At peak production the take-up by the electricity company is capped at 80%, because otherwise they have too much. This is one reason I am getting batteries, to keep my wasted 20%. | |
| Jun 2, 2016 at 13:14 | comment | added | Alexander | @DanGetz "reg." is the abbreviation for "regenerativ", which is the "German" word for "renewable" in energy context, yes. | |
| Jun 2, 2016 at 13:12 | comment | added | sweber | @DanGetz: Yes, I meant "regenerative", though the correct english term is "renewable". | |
| Jun 2, 2016 at 13:02 | comment | added | Dan Getz | @sweber am I understanding correctly that "reg." is an abbreviation for "renewable"? | |
| Jun 2, 2016 at 11:46 | comment | added | Suma | Note: what went negative are not prices for renewable energy (those have minimum price guaranteed by state), rather prices of energy in a general market. See en.wikipedia.org/wiki/Feed-in_tariffs_in_Germany The minimum feed-in prices is about 9 EUR / MWh. | |
| Jun 2, 2016 at 8:06 | comment | added | sweber | @MarchHo: Yes and no... This law changes all few years, and I didn't notice. Sorry for that. The most recent version is EEG2014, and the old §8 now is EEG2014 §11 And §14 now says the grid can now also ask larger reg. energy plants to reduce power output, but latest one day before. So the situation isn't that serious any more, but it's still existing due to the limitations. | |
| Jun 2, 2016 at 7:31 | comment | added | March Ho | @sweber Thanks for the link, but it seems that the law linked is "außer Kraft" which from my limited knowledge of German, means that it is no longer in effect? | |
| Jun 2, 2016 at 7:28 | comment | added | sweber | Some words about WHY: As you wrote, you can't simply shut down a conventional power plant just to switch it on a few hours later again. But you can easily shut down wind plants, and solar cells even don't care if the power isn't consumed. BUT a law to support reg. energy (EEG), says (§8): The grid has to privilege power from reg. energy over conv. energy, and it always has to take all available power from reg. energy. The grid even can't ask the plants to reduce their power output. | |
