General phenomena like inflation (construction cost index rising) and interest rate (cost of capital) rises should affect all technologies proportionally.

The notable thing was that CCGT costs aren't rising to the same extent, despite broadly similar capital cost to utility scale PV (page 11). And longer construction time (pages 37 PV and 39 CCGT), which affects the risk premium.

I recall reading that there was a polysilicon shortage because of changes in China's energy policy. Not sure what's going on with wind. Nor why CCGT costs are continuing low.
