load following power plant

Load following power plants run during the day and early evening. They either shut down or greatly curtail output during the night and early morning, when the demand for electricity is the lowest. The exact hours of operation depend on numerous factors. One of the most important factors for a particular plant is how efficiently it can convert fuel into electricity. The most efficient plants, which are almost invariably the least costly to run per kilowatt-hour produced, are brought online first. As demand increases, the next most efficient plants are brought online and so on. The status of the electrical grid in that region, especially how much base load generating capacity it has, and the variation in demand are also very important. An additional factor for operational variability is that demand does not vary just between night and day. There are also significant variations in the time of year and day of the week. A region that has large variations in demand will require a large load following or peaking power plant capacity because base load power plants can only cover the capacity equal to that needed during times of lowest demand.

Load following power plants include hydroelectric power plants and steam turbine power plants that run on natural gas or heavy fuel oil, although heavy fuel oil plants make up a very small portion of the energy mix. A relatively efficient model of gas turbine that runs on natural gas can also make a decent load following plant.

http://en.wikipedia.org/wiki/Load_following_power_plant

"Load-following" power generators can increase or reduce their output based upon demand, and typically run at 30 to 50 percent of capacity. They are typically traditional gas turbine units, and may be shut down on a daily or weekly basis as needed. Older coal plants, combined-cycle natural gas plants, and some nuclear plants can operate in a load-following mode, but their ability to do so is limited. For example, newer nuclear plants can cut output by as much as 20 percent in an hour, but need as much as eight hours to ramp back up to full capacity.

"Peaking units" typically run for a few hours at a time at low capacity factors when demand reaches unusually high peak levels, like in the middle of a hot summer day. These units are typically simple gas turbines.

Reference: aan- en afschakelen van capaciteit

Reference information:
Om een maximale invulling te krijgen van deze voordelen, dient de Vlaamse overheid een aantal technische voorschriften te bepalen, waaraan slimme meters dienen te voldoen. Het Nederlandse Ministerie van Economische Zaken heeft een aantal eisen en basisfuncties vooropgesteld waaraan slimme meters dienen te voldoen.

A) Op afstand kunnen uitlezen van afgenomen en aan het net terug geleverde energie (meten):

· Verbetering van de operationele bedrijfsvoering van de leverancier (switchen, verhuizen, facturering).
· Verbetering inzicht afnemer in actuele energieverbruik en kosten.

B) Het op afstand kunnen aan- en afschakelen van capaciteit (schakelen):

· Faciliteren operationele taakuitvoering netbeheerder.
· Preventief uitschakelen tijdens noodsituaties.
· Aan- en uitschakelen bij in- en uithuizen van kleinverbruikers (bij tijdelijke leegstand).
· Gedeeltelijk uitschakelen bij wanbetaling.
· Ondersteuning van bepaalde betalingsmethoden zoals prepaid.

C) Het op afstand kunnen meten en signaleren van de kwaliteit van de energieafname (signaleren):

· Verbetering operationele bedrijfsvoering netbeheerder.
· Maakt de detectie van lekkages of fraude mogelijk.
· Detectie van leveringsfluctuaties, onderbrekingen schakeleffecten.

D) Online interactie tussen afnemers en leveranciers (communicatie):

· Online aanbieden van innovatieve producten en diensten (energiebesparingsadviezen, bijzondere tarieven voor bepaalde uren).
· Afnemer kan real time reageren op markt/product/prijsontwikkelingen van leveranciers.
· Ondersteuning van bepaalde betalingsmethoden zoals prepaid.

E) Snelle reactie van regelaars in energie-installaties (regelen):

· Koppeling met domoticatoepassingen (huisautomatisering).
· Koppeling met decentrale (duurzame) opwekking.
· Faciliteert decentrale vraag- en aanbodsturing (afstemmen van eigen productie en afname op gunstige tarieven).

bij- en afschakelen van capaciteit

STEG centrales zijn dus zeer flexibel hebben een hoog rendement. Daardoor zijn de veronderstelde kosten ook niet juist. Een ander merkwaardig beeld dat zij daarbij schetsen is dat er een constante stroomvoorziening is van de basiseenheden. Maar juist ook de vraag naar energie kent fluctuaties van rond de 50%. Ook de huidige centrales zijn constant aan het bij- en afschakelen. Alleen kerncentrales worden constant op stoom gehouden. Daarmee is kernenergie juist in het nadeel tov andere energieopwekkers.

Ten leste doet De Groene Rekenkamer voorkomen alsof er zwaar geinvesteerd moet worden in de infrastructuur van het Net om nieuwe windmolenparken te bedienen. Deze infrastructuur is echter al toebedacht op een dergelijke schakeling. Wat overblijft is zijn aan schakellijnen na het hoofdnet toe vanaf de energieopwekkers. Maar dat geldt voor elke nieuwe centrale, ongeacht welke energievorm deze kent.

Lees ook de reactie van lambertus. Duidelijk terzake doende en prima in staat om het gehele artikel inhoudelijk te weerleggen.

Niet de ‘myth’ van windenergie is busted, maar de myth van de groene rekenkamer.

http://hgroen.wordpress.com/2010/01/15/

Dat op de website www.windenergie.nl naar oordeel van de nationale ombudsman niet alle zienswijzen voldoende belicht zijn, zegt niets over de technische haalbaarheid van het verminderen van de fluctuaties van energieopwekking door middel van windenergie.

Het aangevulde gegeven dat een rendementsverlies optreedt bij het bij- en afschakelen van centrales onderstreept zelfs het belang van meer spreiden en bufferen in de energievoorziening, zodat minder tot geen bij- en afschakelen van centrales noodzakelijk is.

Windmolens en electriciteitsvoorziening

Het probleem van windenergie zijn de onvoorspelbare schommelingen in de productie. Waterkrachtcentrales kunnen zeer snel capaciteit bij- en afschakelen (dit is een kwestie van minuten itt tot uren voor kolencentrales). Daardoor kunnen deze goed dienen als “buffer” voor windenergie. Een andere optie is de schommelingen in sommige toepassingen voor lief te nemen: hoogovens en alumiumsmelters voelen een dipje in het aanbod niet, vanwege de erorme warmtecapaciteit.

  -> Right, my answer is based on the second part of my reference, see added note: "bij- en afschakelen". This means, add and curtail. Initially I misread the question.
