The shortlisted schemes for the site in Cumbria are now available on the Landscape Institute (LI) website.
Shortlisted teams from the Landscape Institute's competition are Iteriad, Stephenson Halliday, Aecom Infrastructure and Environment, One Creative Environments, Estell Warren and HEPLA.
RIBA also ran a competition, with its shortlist including C.F Architects, Faulkner Browns Architects, Graeme Massie Architects, K2 Architects, Reiach and Hall Architects and William Matthews Associates.
The shortlisted ideas were selected by an independent panel of experts, including architect Sir Terry Farrell and Paul Tiplady, former chief executive of the Lake District National Park Authority.
NuGen chief executive Tom Samson said: "We have had an overwhelming response to the competition, both in terms of numbers and the level of creativity in the designs. The architecture and landscape community have embraced the challenge and have delivered some thoughtful, considered and visually breath-taking proposals for our Moorside Project.
"We've narrowed the entries down to five - but we're very keen to hear what the public think of our selection." Email NuGen at email@example.com and include 'Design Competition' in the subject field to comment on the shortlisted designs.
