EXECUTIVE SUMMARY
This report provides the supporting information to the update of cost assumptions and technical inputs
for the DECC Levelised Electricity Cost Model.
The report begins by defining the scope of the work which PB undertook and the general limitations
which were experienced.  The methodology of the work, including the general approach and the data
sources used, are then detailed.  Also, any fundamental changes which had to be made to the model
are explained.
The main focus of the report is an analysis of the methods and assumptions used to update the cost
and technical inputs.  The main parameters of key timings, technical data, capital costs and operation
and maintenance (O&M) costs are discussed in full.
The report is concluded by giving an overview of each technology, in terms of the notable updates
and key reasons behind these updates.  The current state of the technology and any expected future
changes are also discussed.
A summary of the updated cost assumptions and technical inputs have been included in the
appendices of the report, along with the subsequent levelised cost results
