Dr Amy O’Mahoney, Ofgem, United Kingdom Mr Kristian Marr, Ofgem,United Kingdom Shashi van de Graaff, Ofgem, United Kingdom Mr David Hall, Ofgem, United Kingdom In recent years, the generation mix in most electricity markets has been in transition, resulting in larger proportions of variable generation. In GB, wind and solar accounted for 13% and 5% of installed capacity respectively in 2015 , and 11.5% of generation over the same period. This intermittent generation is not always capable of delivering in periods of tightness, and thus contributes considerably less to peak demand. This development in the electricity market has led to changes to how the system is operated. As a result, more flexible thermal plant is now required to run differently than originally intended; wind generation has been shown increase the cycling of existing units (Troy et al., 2010). This relates to additional start-ups, ramping and operation at part load (Denny and O’Malley, 2009; Troy et al., 2010). Analysis of availabilities in other markets has indicated that the availability of CCGTs in GB is below those in comparable markets.

Dr Mona Chitnis, University of Surrey, United Kingdom Prof Steve Sorrell, London School of Economics, United Kingdom Dr Roger Fouquet, London School of Economics, United Kingdom Improved energy efficiency is widely expected to play a key role in reducing energy consumption and GHG emissions. However, the energy and emissions savings from such improvements may be less than simple calculations suggest, owing to a variety of economic mechanisms that go under the heading of rebound effects. Direct rebound effects result from increased consumption of relatively cheaper energy services: for example, an efficient boiler lowers the cost of space heating so households may choose to increase internal temperatures and/or leave the heating on for longer. Indirect rebound effects result from induced changes in consumption of other goods and services, the provision of which necessarily involves energy use and GHG emissions. For example, the money saved on space heating may be spent instead on increased lighting, or on electronic goods. Re-spending therefore may lead to additional energy use and emissions, which offset the original energy and emission savings. This study estimates the direct and indirect rebound Read more…Chitnis-Rebound-effect-for-energy-services-the-case-of-UK-households.pdf 608.72 KBChitnisFouquetSorrell-ReboundEffectsForHouseholdEnergyServicesInTheUK.pdf 846.64 KB
