Joint Oireachtas Committee on Climate Action

Energy Supply and Security: Discussion

Dr. Liam Ryan:

I am happy to come in. We are active and working with EnergyCloud. It is a great initiative to try to help people in fuel poverty, in particular, and where we are looking at energy we cannot use because it is constrained or curtailed on the system, how that can be redeployed to protect the more vulnerable in society. We are active in that space and currently looking at how that energy could be deployed. One challenge and constraint we have is that wires from a region are not able to take that power out of the region into other areas. There, in particular, we see a quick benefit in the deployment of the EnergyCloud solution.

Curtailment is where the system can only take a certain amount of energy, otherwise it becomes unstable. We are pushing the boundaries of that. We can currently operate the system where 75% of our instantaneous electricity can come from renewable sources. As we look out to 2030 and that time horizon, a key thing, as we have talked a little bit about today, is having a balanced portfolio. That is when we talk about 2 GW or 2,000 MW of gas generation which would be also renewable gas-ready into the future, so the potential is there to get to a zero- or net-carbon system and be able to redeploy more energy towards the more vulnerable in society.
