It's not like that thing has an ROI, financially speaking. Turn it off, save the gas money and finish the project. While it could miss some events in the near term, the universe isn't going anywhere anytime soon as far as I am aware.

Unfortunately, usually when it's government budgets, money needs to be burned to justify further budget allocation in the future. From that perspective, it makes perfect sense to keep using diesel to power the place while the project gets delayed while also extending salaries for as long as possible. Funds probably aren't getting mismanaged though. If this project involves multiple nations, I don't even want to know what an approval process even looks like or how long a project change approval would take.
