Sir Robert McAlpine is construction manager to complete the Electric Boulevard phase of the project after replacing Bouygues in 2017 during the preconstruction phase.
The new debt facility was raised from its existing lenders to continue with the delayed phase.
So far facade contractor Permasteelisa has been signed up for the main glazing package and specialist T Clarke will deliver the M&E works.
Phase 3a of the Battersea Power Station project will contain over 500 homes, a hotel, shops and restaurants.
The 42-acre site will also contain a public park and be served by a new Tube station on the new £1bn Northern Line extension, due to open in 2021.
It has been designed by architects, Gehry Partners and Foster + Partners.
Foster’s Battersea Roof Gardens will be styled in a subtle 1930s theme inspired by the Power Station. The northern hooked-shaped end of the building will be home to the art’otel, a new 167-room hotel boasting a rooftop swimming pool and bar.
Gehry’s Prospect Place comprises a cluster of five buildings each with striking sculptural façades inspired by London’s famous John Nash Regency terraces.
Each individual building has its own style. ‘The Flower’ building will sit at the centre of The Electric Boulevard forming a focal point between the other buildings and is destined to be a new landmark for London.
