Tomorrow's Energy Scenarios

Planning Ireland's Energy Future

Tomorrow's Energy Scenarios

At EirGrid, one of our roles is to make sure that the electricity transmission grid is ready for the future. We will develop four possible scenarios which consider how electricity may be generated and used years from now - and what this means for the electricity grid of today. We call this "Planning for Ireland’s Energy Future."

The key to this process is that we examine a range of ways that energy use may change. We gather data and work closely with stakeholders to understand the possible energy futures, and to propose solutions for any problems we find. This allows us to plan for more than one potential impact, rather than basing our plans on just one assumption. This makes the grid stronger and more flexible.

We have worked and collaborated with government departments, government agencies, and energy research groups. In particular, we received strong support from two government departments: The Department of Communications, Climate Action & Environment, and the Department of Jobs, Enterprise & Innovation.

Renewable electricity generation maintains a steady pace of growth. This is due to steady improvements in the economy, and in the technologies which generate electricity.  New household technologies help to make electricity consumers more energy aware. This increases energy efficiency in homes and businesses. Over time, electricity consumers gradually begin to make greater use of electric vehicles and heat pumps. This means that, over time, electricity powers a larger proportion of transportation and heating.

The economy experiences very slow growth. Investment in new renewable generation is only in established, low risk technologies. Due to poor economic growth, new technologies that could increase the use of renewable generation at household and large scale levels are not adopted. Overall there is little change in the way electricity is generated when compared to today. Domestic consumers and commercial users are also avoiding risk and uncertainty. The only source of demand growth is the connection of new data centres but the level of investment slows down significantly after 2025.

The economy enjoys high economic growth. This encourages the creation and rollout of new technologies for low carbon electricity generation. There is strong public demand to reduce greenhouse gas emissions. In addition to high carbon prices and incentives for renewables, this creates a high level of renewable generation on the grid. This clean energy then combines with improvements to broadband and transport to drive growth in large data centres.

A strong economy leads to high levels of consumer spending ability. The public want to reduce greenhouse gas emissions. Electricity consumers enthusiastically limit their energy use and generate their own energy. This results in a large number of community led energy projects and a rapid adoption of electric vehicles and heat pumps in the home.

Recent Consultation

We have published a consultation document in which you will find all you need to know on our draft scenarios. You can find even more information on our draft scenarios in our Appendix document.

We received your feedback on our draft scenarios during our consultation which ran from February to April.

During May and June, we will analyse all feedback received. Your views will allow us to shape the final scenarios which will be published in summer 2017.
