In this study, Baringa has analysed the financial impact for end consumers of the deployment of wind generation in Northern Ireland over the period 2000-2020. We have used our advanced in-house models of the all-island electricity market to calculate how the costs and benefits for end consumers would have differed if no wind farms had been built. We have also calculated the impact of wind farms on carbon emissions and fossil fuel consumption.
Key findings – what have we learned?
- Our analysis indicates that the deployment of 1.4 GW of wind generation capacity in Northern Ireland between 2000 and 2020 will result in a total net benefit to consumers, over 20 years, of £0.1bn (£135 million to be exact), which equates to a net benefit of about £4 per person per year.
- This total net benefit arises as the gross costs of £0.7bn are outweighed by a gross benefit of £0.8bn. These benefits consist of wind-driven reductions in wholesale power prices, and avoidance of EU non-compliance costs.
Aside from the financial costs and benefits, we calculate that the deployment of wind generation in
Northern Ireland avoids:
- 9 million tonnes of power sector CO2 emissions. The total carbon emissions from energy supply in Northern Ireland in 2016 was 4.0 Mt, so a saving of 9 Mt is equivalent to over 2 years of total carbon emissions in the energy sector.
- 72 TWh of fossil fuel consumption at a saving of £1.0bn
We explored the benefits offered to consumers in Ireland in our parallel report, Wind for a Euro. Read more on our Irish study here.
