No, I'm comparing a unit cost (LCOE) to a unit cost (LCOE). This is the only way to do it because solar + batteries are capital-intenstive while fuel-burning is fuel-intensive.
I understand that. Why don't you do your own math, instead of trusting the Lazard's "levelised" assumptions? Many "levelize" for environmental consequences which aren't priced into the market. Problem there, as the market unfortunately doesn't care. I have no idea what they do.
It takes a bit more than 3 X $2.50 mmbtu, to make a MWh of electricity. So $8-10 bucks is the "fuel-intensive" cost ($.008/kwh). Add your peaker cost, amortized by MWh into your rate. @$1/watt build costs, a billion dollar 1GW gas plant, amortized over 20 years,
run half the time, will still output ~87TWh, which divided into that cost would result in another ~$11/MWh.
So, we're at ~$19/MWh, not >$150 "LCOE". Maybe with Lazard's assumptions, we can compare.
Guys, its in these headlights before everything which is not subsidized is deer. Solar City, among other things, has the phase down of the ITC, over the next 5 years, to deal with. Coal bankrupt. Nuclear, which Exelon has demonstrated needs only $19-23/MWh to stay open, is closing. It's just ducky that renewables have achieved PPA rates of $30-60/MWh, without batteries and before the ITC/PTC are added back. Fail to understand how cheap natural gas is, at your peril.
