I doubt that would be allowed by the current administration. Even actual power plants that don't meet current environmental standards were restricted last week in Texas. They were allowed to run, but required to sell power for no less than 10x the usual price.[1] It seems like a diesel train or jet engine would be even worse for the environment, per kWh, and even less likely to get federal approval. https://www.energy.gov/sites/prod/files/2021/02/f82/DOE%20202%28c%29%20Emergency%20Order%20-%20ERCOT%2002.14.2021.pdf https://www.energy.gov/sites/prod/files/2021/02/f82/DOE%2020...
