It's true that low oil prices will encourage oil fired plants to open back up,but I'm not sure that a very short term drop is going to have much effect since spinning up and down a power plant isn't exactly a short term decision.

Most of these plants are on 7 day standby - Ie. They need to be able to reopen within 7 days in case of war or disruption to gas supply.
