Da welcomes disconnection of 800 illegal connections

It seems like you're referring to a recent development in the energy sector. "Da" is likely a typo, and I'm assuming you meant to say "The" or "A".

So, to clarify, it appears that the authorities have disconnected around 800 illegal connections in a particular area. This is a significant step towards ensuring the safety and efficiency of the energy distribution system.

Can you please provide more context or information about this development? What specific location or region is this related to?
