Since 1 January 2014, Uisce Éireann has statutory responsibility for all aspects of water services planning, delivery and operations at national, regional and local levels, under section 7 of the Water Services (No. 2) Act 2013. Water usage management and conservation across commercial and industrial (non-domestic) sectors, including data centres, is an operational matter under the remit of Uisce Éireann. Accordingly, I have no function in relation to this matter.
Uisce Éireann has a dedicated team to deal with representations and queries from public representatives that can be contacted via email to oireachtasmembers@water.ie or by telephone 0818 578 578.

I, as the Minister, have no function in this matter and this data is not held by my Department. The connection of projects, including solar projects, are matters for ESB Networks and EirGrid. As such the Deputy may wish to engage with these organisations directly. Both entities have dedicated email addresses for such queries, oireachtas@esb.ie and oireachtas@eirgrid.ie.
