The splitting of water is an endergonic (non-spontaneous) reaction, and thus would require energy (chemical work to be done) in order to happen.
In Photosystem II, the OEC enzyme catalyzes this splitting, but where does it get the energy from? Does it use ATP?

As I (mis)understand it, the energy comes from absorbed photons.
