Generation expansion planning and long run marginal cost calculations using the ENPEP-(WASP) computer package

The association of the Electricity Authority of Cyprus (EAC) with the IAEA commenced with a training course on Electric System Expansion Planning and the use of WASP-III at Argonne National Laboratory, late in 1984. At that time, both the Government of Cyprus and EAC relied mostly on external Consultants for conduct of energy and electricity planning studies. A great effort was therefore required to establish this, new for Cyprus, planning methodology. The release of ENPEP which is an integrated PC-based Energy and Power Evaluation package made the use of WASP very much easier and accessible to power system planners. Through continuous efforts these computer models have now been established in the Planning Procedures of EAC and are sued extensively to a degree that it was difficult to imagine five years ago. This paper contains some of the experiences gained in the use of these models in electric system expansion planning and the long run marginal cost analysis. (author). Figs and tabs
