Effect of alternative fuels on 'Total cost of electricity production' - What are the costs for biofuels? #1298

Closed Richard-Deuchler closed 11 years ago

Richard-Deuchler commented 11 years ago

Display the chart 'Total cost of electricity production', lock it and go to "Alternative Fuels". Screen Shot 2013-03-11 at 16 53 24

_When switching to 50 % biocoal, the production costs of Pulverized coal increase. However, switching to 50 % wood pellets (and 50 % coal) makes the production costs actually go below the default._

I checked the carrier / defaults.yml

Both green carriers seem to have the same (non-defined) price. But somehow, they lead to opposite effects in the frontend.

The price is defined here and makes the green options more expensive.

There are, however, more factors than the carrier price that determine the final cost: most notably the co2-price and the carrier-dependent efficiency. We need more research to determine if there really is a bug here IMO. @Richard-Deuchler feel up for it?

I'll have a little look tomorrow. Indeed, the CO2 emissions might be the reason... -----Original Message----- From: Chael Kruip notifications@github.com Date: Mon, 11 Mar 2013 09:28:10 To: quintel/etmodeletmodel@noreply.github.com Reply-To: quintel/etmodel reply@reply.github.com Cc: Richard-Deuchlerrichard.deuchler@quintel.com Subject: Re: [etmodel] Effect of alternative fuels on 'Total cost of electricity production' - What are the costs for biofuels?

I can only observe the effect in John's scenario: http://www.energietransitiemodel.nl/scenarios/138587 For default scenarios, and individually adapted CO2 and fuel prices, the behavior can be explained by the lower efficiency linked to wood pellet use. However, John's scenario indicates that wood pellets reduce the costs for electricity production, while biocoal causes an increase.

Richard-Deuchler commented 11 years ago

John's original scenario used old outdated update statements, see https://github.com/quintel/etengine/issues/530. This issue is no longer observed in the cleaned up scenario http://energytransitionmodel.com/scenarios/138851. Here, both green carriers lead to exactly the same costs. Closing.
