Completed Annexes

HPT has been active since 1978, with a lot of collaborative research, development, demonstration and deployment projects. We call these projects "Annexes" and they are conducted on a combination of cost sharing and task-sharing basis by the participating countries. Here you can read about the finalized projects, from 1989 to this present date.
