TSLA will win
Not sure I follow. It seems to me they directly address what types of generating plants would be used at what time of day to meet the additional demand:
How would it become clear to you that these sentences (which you quoted) are not simply referring to the existing mix at that time of day?
The paragraph which appears the most relevant to this question is "Generator Dispatch" in the introduction. It seems to explain everything in terms of cost structures, but doesn't really answer my primary questions:
Would the utilities be able to use mostly natural gas?
How much would it cost them?
Would a higher price on CO2 (higher than $50/tonne) have any effect? How high would it have to be, and which effect would it have?
Are there any other measures (other than new technology) which could have an effect?
If there was a program for EVs to purchase NG-made electricity specifically, how much would it cost the utilities to provide such a program?
Which questions would you have, and do you see them answered?
The differences between the two utilities are apparently based on the different mix of generators. What would change if they bought a small number of additional NG generators? (If they don't want to buy wind, that is.)
That paragraph suggests (to me) that it is all determined by given-as-fact SRMC curves, and not even a $50/tonne CO2 price can do anything about it.
In general, I find it an interesting study, but it doesn't (yet) go far enough. Another limitation is, of course, it models PHEVs with a limited battery capacity which use gas when the battery is empty, not pure EVs.
I did enjoy reading these sentences:
It is reasonable to expect that recent shale gas exploitation will keep oil use low in New York in the next decade. Thus, our “all natural gas” scenario is likely to better represent future NYISO emissions from charging PHEVs than the 2005 data.
When compared to 2020 CAFE standards, net CO2 emissions in New York are reduced by switching from gasoline to electricity; coal-heavy PJM shows somewhat smaller benefits unless coal units are fitted with CCS or replaced with lower CO2 generation.
