The “Ireland’s Grid Development Strategy” is Eirgrid's ongoing development plan to deliver a sustainable, competitive and secure electricity supply to homes, businesses and industries in Ireland. This builds on the original grid development strategy “Grid25”.

The strategy will help Ireland meet its 40% target, for electricity generated from sustainable Irish sources, by adding transmission capacity to the grid. Under the strategy, between 3,800 and 4,100 MW of wind capacity will be added to the grid to achieve this target. This is an increase in the requirement for wind capacity forecast in 2015.

In order to manage the operation of the power system over the coming years a programme of work has been established entitled “Delivering a Secure Sustainable Electricity System (DS3)”.

This programme was established following a comprehensive analysis of the long-term needs of the power system.

The key message from this analysis is that the 2020 renewable targets are achievable; however, significant work is required to manage the integration of very high levels of instantaneous renewable penetration on the island.  

The deployment of renewable energy sources (RES) in the electricity sector has been increasing steadily in recent years and Ireland and Northern Ireland are committed to increasing the level of renewable electricity consumption to 40% by 2020.

The EirGrid Group is at the forefront of this change and is working with all industry stakeholders to facilitate these ambitious renewable electricity targets.
