In the 2013 election Horgan again won the Juan de Fuca riding, this time against BC Liberal candidate and Sooke councillor Kerrie Reay and Green Party candidate Carlos Serra. On the local level, his campaign focused on transportation issues and regional growth while on the provincial campaign he promised a comprehensive review of BC Hydro, in particular its debt load, commitments to independent power producers, and future infrastructure requirements, and advocated a market-driven approach to creating a liquefied natural gas industry, in contrast to the BC Liberal approach, at the time, of presenting expressions of interest as committed future revenue. The NDP were favoured to win the general election but, while Horgan won his riding, the party again formed the Official Opposition with Horgan returning to his role as critic for the energy portfolio in the 40th Parliament. Shortly after the election, Horgan and Minister of Energy and Mines Bill Bennett exchanged op-eds regarding new BC Hydro rate increases and cost overruns in the Northwest Transmission line project.
