Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what assessment his Department has made of the relative efficiency of combined cycle gas turbines and reciprocating gas and diesel engines.

The Department last published estimates of the efficiency of different technologies in 2013 [1]. As the design of many of these technologies is rapidly changing, we expect to publish an update of the evidence in due course.
