A Footnote on IER, its LCoE and Other Studies

(Lecture Notes)
As mentioned early today, the Institute for Energy Research is a thinktank which denies anthropogenic climate change and also has much link to conventional power industries. Below is a link directed to an article with more detailed information of this thinktank.

To give a balancing picture and also introduce one of my favorite pro-renewables media, the following link gives what CleanTechnica has said on the LCoE of renewables.

One can easily see that the LCoE IER estimated for renewables is almost always near the high estimated side.

I happened to know the background of IER because it published a grid study this June claiming Calfornia has too much solar power and is causing grid instability, neglecting a more crucial point to this problem: the inflexibility of California’s nuclear and coal fleet (so called “baseload”), which the state plans to phase out by 2025.

The German official stance to a similar issue in Germany can be seen in the link provided below (in German, but you could use Google translator to get the rough meaning as I did; in case I misinterpreted the graphs please let me know), where the potential of lowering conventional power output during negative price period is fully discussed. Afterall, Germany still has too much coal, so as so that they have a constant cheap wholesale price and continue to export coal to nearby nations.

Additional Notes on Germany’s Coal
There are many ways to fix the current situation. Closing down uneconomic hard coal plants is one. They are already being marginalized by brown coal, and are forced to do the load matching job already, which is something natural gas station can do better with less carbon emissions.

Of course, brown coal power plants are the real socio-economical challenges in Germany. Some will begin to be mothballed in 2018, but more still needs to be done. On that matter, we’ll see how the Greens could achieve in the upcoming Jamaica coalition.
