Summary/Abstract

This paper investigates the impacts of including 500 MW of wave power into Ireland's electricity generation portfolio in the year 2020. One year of detailed market simulations are undertaken to determine the impact on wholesale electricity prices, system operation costs and CO2 emissions with and without this installed wave power under a number carbon prices assumptions. In both scenarios (with and without wave energy), Ireland's installed renewable capacity is fixed such that 40% of Ireland's electricity in 2020 is from renewable source. The likely revenue a wave energy device would earn in the market is also investigated and compared with what is required to achieve 500 MW installed capacity. It is shown that in general the inclusion of wave energy has a negligible effect on wholesale electricity prices, reduces total system cost in Ireland and can increase CO2 emissions on the island of Ireland under certain carbon price assumptions. It is also shown the current REFIT for wave energy is adequate.

Summary/Abstract

This paper focuses on the impact of electric vehicles on electricity generation in Ireland in 2025 based on five alternative generation portfolios. The year 2025 was selected for assessment due to the information on the composition of the five generation portfolios from Eirgrid the system operator in Ireland being provided. Detailed market simulations were undertaken on the five possible generation portfolios to assess the impact of the Government targets for electric vehicles on the generation costs, emissions, generation stack and the cost to load of this additional demand. This paper also studied the impact between a standard and least cost electric vehicle loading regime to ascertain the benefits that could be achieved. The results show that gas will be the dominant source of electricity generation to load electric vehicles and that wind as an electricity source will experience a minor reduction in curtailment, with the least cost charging profile showing a more pronounced reduction. The capital benefits of the Standard and Least Cost EV load are found to be negligible. The portfolios studied generated CO2 emissions per kilometre between 52 and 70 gCO2/km. All portfolios with the exception of coal were found to comply with EU regulation 443/2009.
