You could disconnect from it. That's much easier said than done and probably very complicated by the occupation, but I would guess that disconnecting would reduce coal consumption and greenhouse gas emissions proportionally to power usage.
I should also note it is primarily a gas plant, fuelled by extremely cheap (nearly free) gas subsidised by Russia. It only falls back to coal when supply is disrupted, which happened when Ukraine stopped transiting Russian gas on its territory.
Arguably, they are a particularly big problem to Moldovans because Russia's military is funded by greenhouse gas emissions.
