<p>In comparing the costs of different electricity technologies in the future, DECC
typically use the levelised costs of electricty generation. Levelised costs include
capital and operating costs over the lifetime of a plant, as well as DECC estimates
of projected fuel and carbon costs.</p><br /><p>The most recent levelised cost estimates
are available in the DECC Electricity Generation Costs (December 2013) report, available
at:</p><br /><p><a href="https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/269888/131217_Electricity_Generation_costs_report_December_2013_Final.pdf"

/><p>We are currently undertaking a comprehensive review of our evidence on levelised
costs of electricity generation.</p><br /><p>The above levelised costs however do
not take into account all of the wider positive or negative impacts that a plant may
impose on the electricity system. So far, DECC’s electricity modelling has considered
these wider whole system impacts through a system wide cost-benefit analysis. DECC
is currently undertaking a project, which aims to further systematise DECC’s understanding
of the whole system impacts of electricity generation technologies.</p>
