I'm not sure I fully understand your question ... but, if you are using the runopf_w_res function in MATPOWER, I believe the LAM_P column in the bus matrix should give you the correct energy price. I'm not sure what you mean by forming the energy price "independently of reserve prices". When co-optimizing, by definition the allocation of energy and reserves (and therefore energy prices) are interdependent. That is, the amount of required reserves and the relative reserve costs will affect the energy dispatch and the nodal marginal price of energy.
