It's Been So Windy in Europe That Electricity Prices Have Turned Negative (vice.com)

An anonymous reader writes: It's been very windy across Europe this week. So much so, in fact, that the high wind load on onshore and offshore wind turbines across much of the continent has helped set new wind power records. For starters, renewables generated more than half of Britain's energy demand on Wednesday -- for the first time ever. In fact, with offshore wind supplying 10 percent of the total demand, energy prices were knocked into the negative for the longest period on record. The UK is home to the world's biggest wind farm, and the largest wind turbines, so it's no surprise that this was an important factor in the country's energy mix. "Negative prices aren't frequently observed," Joel Meggelaars, who works at renewable energy trade body WindEurope, told Motherboard over the phone. "It means a high supply and low demand."

      Not really. It's nothing to do with keeping grid voltage constant - voltage is a local phenomenon in the grid and is a reflection of current vector flows through the complex impedance, such that you don't need power plants to raise or lower the voltage, but instead, this is done by capacitors/inductors/variable phase shift transformers and variable ratio transformers.

      Negative energy prices are a symptom of having too many power plants with no incentive to reduce output in an oversupply condition.

      There are many reasons why a plant may not wish to reduce power:
      - a thermal plant may already be operating at close to its minimum rated power, and may require the operator to waste steam to reduce electricity output, because the plant cannot sustain a lower steam production (in such a condition, there is a loss of revenue, but no reduction in fuel costs, so is undesirable - unless prices turn negative at which point steam waste may be judged appropriate).
      - Renewable and nuclear generators which have zero, or near zero, marginal operating costs are reluctant to reduce output as it reduces revenue, without a saving in fuel costs
      - Subsidised power generators (which in the UK model sell the power to the govt at a fixed price, and the govt then sells it on the open market) do not have to respond to market forces, so have no incentive to reduce power output, even in the event of negative prices.
      - Some plants, such as the old UK nuclear plants, are limited by fatigue life, and therefore must avoid temperature and load changes, except for plant operational reasons, and therefore are reluctant to reduce load, even in the event of negative prices.
      - Renewable electricity is legally required to hold a "privileged" position in the energy market, such that it must not be curtailed if any other source can be curtailed first. In the event that for technical reasons, renewable energy must be curtailed (e.g. very high local wind conditions resulting in local grid overload), the compensation that must be paid to the wind generators is very high (up to 10x the value of the subsidies curtailed).

      The reason for this is indeed subsidies, which you pay for in taxes. So the state subsidizes "green" power, but you can't just turn off your nuclear and other plants, that would be both dangerous and take days to recover. So you keep supplying power and as always, the only option is to turn off flexible generators (solar and wind), the problem is that you now have a bunch of money the government gives you per kWh the green energy plant "generates" but there is no demand and you can't legally keep/collect the money, so now the people that have paid for the futures of the green energy plant get paid back based on how much the plant would've generated if it were running.

To reduce power, the speed of the core coolant circulators is reduced. The resultant rise in core temperature results in a loss of core reactivity and a drop in reactor power. A control loop then controls the steam valves to the turbine to bring steam outlet temperature back to set point. After power has changed, rod control can be used to restore core outlet temperature.

      The problem with the AGR design is that the RPV is inaccessible except through the rod ports and a limited number of inspection ports. This makes repair or replacement of moderator elements and structural elements impossible, and this also includes the steam generators which are integral to the RPV. For example, Heysham 1 reactor 1 suffered a fatigue weld failure on a steam generator support. Due to lack of accessibility, this failure is irreparable, and consequently, the steam generator had to be plugged, although the plant is now running on the remaining 7 steam generators.

      The minimum requirements for the manoeuvrability capabilities of modern reactors are defined by the utilities requirements that are based on the requirements of the grid operators. For example, according to the current version of the European Utilities Requirements (EUR) the NPP must at least be capable of daily load cycling operation between 50% and 100 % of its rated power Pr , with a rate of change of electric output of 3-5% of Pr per minute. Most of the modern designs implement even higher manoeuvrability capabilities, with the possibility of planned and unplanned load-following in a wide power range and with ramps of 5% Pr per minute.

      Some designs are capable of extremely fast power modulations in the frequency regulation mode with ramps of several percent of the rated power per second, but in a narrow band around the rated power level.

It could be automated, but right now there is really no need to and it might make the system more unpredictable depending on how many actors there are in the market.

      In any case, wind power plants don't usually get turned off if the price is just slightly negative or zero since turning them off can have other costs; in Germany, for instance, wind power plant operators are entitled to be compensated a set price per kWh produced; whenever their plant gets turned off they still get compensated for the energy they could have produced. The paperwork of compensation for these events (when the grid operator or pool operator turns off the plant) has a cost, and as such actors look at whether or not they are better off letting the turbine run or turning it off.

      The weird thing is that wind and solar and other renewables are the power generators that tend to get turned off first; coal and nuclear cannot be turned off or throttled nearly as fast and have considerable cost ramping up again (both in fuel expenditure and equipment churn); they are also often sold at a set price months to weeks in advance, so they don't get affected by so-called negative energy prices; really, negative energy prices only happen in day-ahead and intra-day markets, which coal and nuclear almost never get sold in; in a case of surplus power, these fossil fuel-based power generators rarely if ever get turned off or down.

    Unfortunately, no. In any given year, there are less than 100 hours where the energy price is negative (ok, I'm fibbing here and haven't looked up the exact amount, but that's the general ballpark). In order to use a couple MW or GW of power to mine bitcoin, however, you have huge capital expenditures in bitcoin mining equipment -- which swiftly loses value over time as new generations of chips are introduced -- so the chip you are using at easter might be a lot less efficient compared to the competition at xmas; if you only use negative price energy periods (if you can even get on that market, the barriers to entry are rather high), you simply can't recoup the hardware costs at all and will be running at a loss.

    If you are mining anyway, sure, negative prices could be a boon -- but I know of no bitcoin mining operation that is actually trading on the energy exchanges and as such they can't really take advantage of this fluctuation.

  26. Negative Power Frequently Happens in the NW US by Anonymous Coward · · Score: 0

    Keep in mind that negative power pricing happens at the wholesale level. Unless you can buy power at the wholesale level, you will still pay your regular rate.

    The large amount of renewable resources (mostly wind) and hydro electric run of the river (very little storage capacity) generation, when water flows are high and the wind is blowing, force the dams to spill water. Spilling water over the top of the dam (versus running water through the turbines or the fish facility) adds dissolved nitrogen into the water which makes the fish down stream "drunk". Hydroelectric operators spend big bucks (tens of US$ per fish per year) to keep the fish happy and alive rather than loopy and food for a predator. Hydroelectric generation operators can also be fined for contributing too much dissolved nitrogen to a fish habitat.

    To avoid this, hydroelectric generation operators will pay (again, at the wholesale level only) other utilities to take excess power off their hands so they don't have to spill water.

      Mostly correct. This is old news in the PNW. A few corrections: - Spill almost never happens over the top of dams, they have spillways for this. - Forced spill due to negative prices (called lack of market spill) is the last thing to happen when prices are negative, because of the water quality issues you describe. Wind gets cut before any spill happens. - The Bonneville Power Administration (biggest energy wholesaler in the PNW) does not pay negative prices.

    In fact, our network prices are so crazy high that we pay roughly 40 cents per KWH just for transportation AND taxes on transportation. Yes, that's nearly half a dollar per KWH!

    aso.
    so if a fuse in between a yuge generator and the first step up transformer blows then ...
    the generator "runs-away" because there's no load because the circuit is not closed (but open because of the blown fuse)?
    i don't think so.

    anyway, the grid is synced, thus if you have 50 Hz and a peak (of the sinusoidal curve) at point A and then you have a point B, 300 km (or more) away, it will have the peak at exactly the same time. call it spooky action at a distance.

    if there's no resistance or load or consumption then the generators will keep spinning at 50 Hz BUT MUCH MORE EASILY.
    there might even be the situation, that because renewables are having a good, sunny and windy day that they are "carrying"
    much of the connected loads, which leaves the "base load" generator, which can have a generator axle made from metal weighing several tons, to spinning close to free, or in other words, to keep the 50 ton generator axle spinning at 50 Hz,
    you could connect some gears and a DONKEY (one donkey power) that WALKS in circles and it would have enough power
    to keep the yuge ton axle spinning constantly at 50 Hz.
    of course if a storm front moves in over the solar panels, their output would drop and the poor donkey at the base
    load generator would start feeling a rather large physical resistance. now one could add more donkeys -or- drop
    the clutch and start releasing steam from a boiler onto a turbine that is connected to the generator axle -or- fire
    up the bolted to the earth jet-engine which is connected to it the same manner.
    of course, one could remove the donkey and replace it with a semi-YUGE electrical motor that would absorb the
    excess energy to keep the yuge generator axle spinning (http://en.wikipedia.org/wiki/Synchronous_condenser).

    of course would could also use the excess energy to build more wind turbines or grow more poly or mono silicon crystals.

    or one could use the excess energy to heat up the steam boilers of the coal power plants instead of coal.

    For falling micro donkeys, as in case of dams, that use molecule sized donkeys, if there is little load or the load is
    carried by the renewable already, then less donkeys per second need to be released from the donkey dam to keep the generator axle at 50 Hz.
    in the same manner if a storm front moves in, looking to release vaporized donkeys into the donkey dam, the solar panels will output less energy and the generator at the dam will feel a "breaking power" (it picks up the slack), but since the grid wants 50 Hz, more donkeys per seconds needs to be released to "push" on the generator axle (via turbine blades).

    maybe, just maybe, it's time to make the so-called "base-load" generators and turbines renewable-compatible. research and investment, good stuff(tm). or just hock up some batteries.

    on a personal note, when i am not home, i am not using my solarpanel, grid-synced electricity generator ... AT HOME. but i get a smile, if i ride a lift or enter a air-conditioned shop because it think: "some of this happens because of my solar panels at home" ... and thus everybody should get the same price they pay.
