Largest contract, at £40m, for the construction giant is for the development of overhead transmission infrastructure in Queensland, Australia.
Construction giant Balfour Beatty's specialist power engineering arm has won contracts worth £400m in the UK and Australia.
The largest contract, coming in at £40m, is for the development of the overhead transmission infrastructure in Queensland, Australia for Powerlink Queensland in a joint venture with United Group Infrastructure of Australia.
Back in the UK, Balfour Beatty Power Networks has won a four-year extension to its existing contract for Central Networks. Under this deal, worth £40m per year, BBPN will continue to be external service provider to Central Networks, which runs the electricity network in central England.
