[email protected] ABSTRACT The Republic of Ireland and UK governments have put forward an ambitious target of 40% of electricity generation to be supplied with renewable sources by 2020. The dominant source of this energy is anticipated to come from wind power, as this is the most mature renewable technology. However, wind generation is inherently variable in its output, and this introduces significant challenges for the System Operator when balancing supply and demand. Although demand side management, energy storage and greater interconnection are all anticipated to help with dealing with the challenge of variability, conventional thermal generators will have a very significant role to play in balancing supply and demand. Running conventional generation more flexibly in order to cater for a wind led regime reduces the efficiency of the plant, as well as shortening its lifespan and increasing O&M costs. The link between variability and the impacts on conventional generation is not well addressed in current literature, but is of vital importance for informing the development of the generation mix.
