Vizier87

not to mention, how old is your energia install?  There are a lot more boards supported now.  Energia 10 can be downloaded from http://energia.nu/download/
 
Technically speaking, other (or really almost ALL) msp430 chips are supported by the underlying C & C++ compiler and debug/programmer tool (mspdebug), but Energia's wiring core would need specific support for the chip since Energia provides more than just an IDE--it provides a simple hardware-abstraction-layer type of framework to support the chip's hardware.
 
Which chip(s) do you have in mind?

@@Vizier87, other parts can be supported but as above answers mention, you will need to port/create a board file entry for them. If you are asking about just programming other devices with code that was done outside the Energia framework then yes. You can use mspdebug that is included in Energia to program the device using the programmer that is on the launchpad. The command would be mspdebug rf2500 --force-reset prog <your hex file>.hex. mspdebug is located in the directory: hardware/tools/msp430/mspdebug
