Transmission system operator Eirgrid and grid maintenance and construction group ESB Networks have released the full list of renewable energy projects to receive grid connection offers in Ireland through their enduring connection policy (ECP) process, with solar PV representing the majority of these.

In total, 85 projects – representing 2,897MW – are due to receive connection offers under Category A of ECP 2.2, with the second stage of the ECP (ECP 2) being split into three batches of connection offers (ECP 2.1, ECP 2.2 and ECP 2.3).

Of these, 61 are solar PV with a collective capacity of 1,533MW. There are also two battery storage projects with a collective capacity of 150MW, and 6 hybrid solar-plus-storage sites consisting of 325MW of solar and 441MW of battery storage.

This includes a 185MW hybrid solar-plus-storage site in Louth under development from Strategic Power Projects. The Monvallet project is split into 50MW of PV and 135MW of battery storage, with the storage element to provide system services and security of supply to the grid.
