The entire Midwest Energy Market (MISO) does not use DST, but not by disabling it but by setting their org's timezone to EST. On one hand this simplifies a lot – days are always 24 hours for example. But it does complicate interop outside of the market since energy is traded with DST based markets, and gas is bought using the gas day clock (also DST). The gas day starts at 10am eastern prevailing time, eg. 9am is yesterday, 10am is today.
