New technologies aren't grayed out if another construction was started during the deployment of the enabling structure.
How to reproduce:
deploy MCV
order construction of power plant
while the first power plant gets deployed, order another power plant
-> once the first one is deployed, the new technologies are available and not grayed out, so they can be ordered although the second power plant is still in construction. Ordering a new construction cancels the old construction without refunding.

Same behavior with refinery and weapons factory.
