Nope. You only pay XP to purchase Force power.
Also, be aware of the Force rating requisite. Bind & Battle Meditation require 2+. Protect/Unleash requires 3+.
Narratively, it would help if you alert me to when you intend to buy a power from a NEW Force power tree; sometimes spontaneously exhibiting new powers makes sense, but sometimes we might want something a bit more narrative (e.g. Master Uvell makes an appearance, you discover something in a temple, a Force-sensitive species of Kabal teaches you something, etc).
