Ireland's electricity system is entering a period of unprecedented change. As demand continues to grow and renewable generation becomes a larger part of the energy mix, the conversation around energy security has never been more important.
Our recent feature in The Irish Times, Ireland's Hidden Power Plant: Why Flexible Demand is Key to Ireland's Energy Security, explored a simple but often overlooked idea: alongside investing in new generation, grid infrastructure and interconnection, Ireland also has a significant opportunity to make better use of the electricity system that already exists.
That opportunity lies in energy flexibility.
Across the country, businesses already have flexible energy assets that can support the electricity system when it needs it most. Whether it's adjusting electricity demand, optimising battery storage or making better use of on-site generation, these assets can collectively act as a virtual power plant, helping to balance supply and demand while creating commercial value for participating organisations.
This matters because Ireland's electricity system is under increasing pressure. EirGrid's latest adequacy assessment points to a tighter electricity supply outlook between 2026 and 2028, while the country's ambition to achieve 80% renewable electricity by 2030 will require greater flexibility across the system. Demand response enables businesses to reduce or shift electricity consumption when the grid is constrained, helping to improve resilience, integrate more renewable generation and reduce overall system costs.
For businesses, participation is about more than supporting the grid. Demand response can create an additional revenue stream, reduce exposure to peak electricity prices and unlock greater value from energy infrastructure that already exists. Rather than viewing energy purely as an operating cost, organisations can transform flexibility into a strategic asset.
As highlighted in our Irish Times feature, organisations including daa and Microsoft are already demonstrating how energy flexibility can support both operational resilience and Ireland's wider energy transition. Their experiences show that flexibility is no longer a future concept. It is already delivering value today.
New generation, storage and network investment will all remain essential. But these solutions take time to deliver. Demand response offers an opportunity that is available now, making better use of existing assets while strengthening Ireland's electricity system for the future.
Ireland's hidden power plant already exists. The next step is unlocking more of it.
