Solar growth in Ireland could provide an annual saving of €21 (£18) per citizen, according to a new report from international advisory firm, AFRY. It modelled three scenarios with different levels of solar and wind, to establish the most effective way of meeting the Government’s target of 70% renewable electricity by 2030. Within these, the highest solar scenario saw a total €106 million (£91.5 million) annual saving, as there are significant benefits from a diversified portfolio of generation assets. If Ireland is to install enough solar to power 1.2 million households as shown in this high penetration scenario, fewer less efficient fossil fuel generators will be required during the daytime, when operational demand is at its highest. This also leads to a reduction in greenhouse gas emissions, which fall 8% in the high solar scenario.
