This paper analyses the medium-term effects of a carbon tax on growth and CO2 emissions in Ireland, a small open economy. We find that a double dividend exists if the carbon tax revenue is recycled through reduced income taxes. If the revenue is recycled by giving a lump-sum transfer to...

We evaluate how increasing wind generation affects wholesale electricity prices, balancing payments and the cost of subsidies using the Irish Single Electricity Market (SEM) as a test system, with hourly data from 1 January 2008 to 28 August 2012. We model the spot market using a system of...

This paper evaluates the likely effect of REFIT, the Irish scheme to support renewable electricity generation, on the wholesale price of electricity. The cost of REFIT is passed on to Irish consumers. Here we calculate that when there are 4071MW of on-shore wind in the Republic of Ireland the...

In this paper we analyse the 2008 electricity price in the Irish All-Island Market. We test whether this price is 'efficient' by comparing it to the electricity price in Great Britain. This analysis suggests that around €16 per MWh of the difference in wholesale prices between Ireland and...

This article considers the possible effects on electricity costs of implementing The Brighter Evenings Bill, 2012, which would move Ireland to Central European Time (CET). The results suggest that such a change would produce very limited savings in peak de mand for electricity and possibly some...

The Irish Single Electricity Market is establishing how to comply with the European Union Target Model. One option is to move away from the regulated environment used in the current design and allow generating firms to bid freely in the market. This study shows that in 2011, allowing firms to...

This paper evaluates the effect of wind generation on CO2 emissions using 2008-2012 historical data for the Irish Single Electricity Market. Wind generation decreases CO2 emissions, but by less than the average system emissions. When we evaluate the results by technology, we find that wind...

The Moneypoint coal plant is nearing the end of its useful life and will need to be replaced. For Moneypoint's replacement, we consider different types of baseload technologies: coal plants with and without carbon capture, combined-cycle gas plants and a nuclear plant. This paper compares how...

In a deregulated market, the decision to build new thermal power plants rests with private investors and they will decide whether to invest on the basis of expected profits. This paper evaluates how such profits are affected by the increasing presence of wind generation. We use hourly historical...
