The session follows recent announcements of inflation-busting price increases by Npower, Scottish Power and EDF Energy.
OFGEM and Energy UK will be questioned about competition in the UK energy market at a public session of the Business, Energy and Industrial Strategy (BEIS) Committee.
MPs will examine the factors that can influence energy price changes and whether OFGEM has adequate powers to intervene in response to increases that it sees as excessive. The session will also focus on the extent to which increasing competition on the supply side of the market and other measures can help to overcome the reluctance of many customers to switch supplier.
MPs will question OFGEM Chief Executive, Dermot Nolan, and Senior Partner for Consumers and Competition, Rachel Fletcher. It will also hear from Energy UK Chief Executive, Lawrence Slade, and Director of Retail Energy Supply, Audrey Gallacher (formerly of Citizens Advice Scotland)
Energy UK represents more than 90 gas and electricity suppliers, including EDF, E.ON, British Gas, Scottish Power and SSE.
The meeting can be viewed live at Parliamentlive.tv from 10.00am on 22 February 2017.
