Why is my bill so high with txu?

Excuse me, could you please explain to me why my bill with TXU has been unusually high this month? I've been trying to conserve energy and make sure that all appliances are turned off when not in use, so I'm quite surprised to see such a significant increase in my charges. Is there a possibility that there's been a mistake in the billing process, or is there something specific about my usage that's causing this? I'd really appreciate it if you could help me understand the reason behind this hike in my electricity bill. Thank you.
