'Einspeisen' (to feed in / to input) is a separable verb. The prefix 'ein-' goes at the end of the main clause. In subordinate clauses and in the infinitive with 'zu', the verb stays together.
Die Anlage speist täglich mehrere Kilowattstunden ein.
The system feeds in several kilowatt-hours every day.
The verb 'einspeisen' (to feed in / to input) is almost always used with the preposition 'in' followed by the accusative. The structure is: etwas in ein System einspeisen (to feed/input something into a system).
Wir speisen die neuen Adressen in die Datenbank ein.

You can recognize the meaning of 'einspeisen' (to feed in / to input) from the object: if it is about 'Strom' (electricity) or 'Energie' (energy), it means feeding into a grid. With 'Daten' (data), it refers to a computer system. With 'Nahrung' (food/nutrition), it is a medical context.
Die Solarmodule speisen Energie ins Stromnetz ein.
The solar panels feed energy into the power grid.
In the context of energy, typical combinations are 'Strom ins Netz einspeisen' (to feed electricity into the grid), 'Wärme einspeisen' (to feed in heat), or 'Energie aus erneuerbaren Quellen einspeisen' (to feed in energy from renewable sources).

The meaning 'Nahrung zuführen' (to supply food/nutrition) is limited to medical jargon. It is used when patients are fed artificially, for example through a tube or infusion.

The patient had to be fed liquid nutrition through a stomach tube.
to deliver / provide
'liefern' and 'einspeisen' can both mean that something goes to another place or into a system. The difference lies in the direction and the context. 'liefern' is mostly used for goods, packages, or also results: someone brings or provides something for someone. 'einspeisen' fits better with electricity, heat, or data: something is fed into a grid, a technical system, or a database. Learners may confuse the words because both have to do with passing something on. As a practical rule: packages and results are 'geliefert' (delivered/provided), while electricity and data are 'eingespeist' (fed in/input).
