In this paper we compare different approaches to account for start-up costs when modeling electricity markets. We restrict the model formulation to either linear or mixed integer problems in order to guarantee a robust solution. The results indicate that the choice of the model has a significant...

Electricity transmission has become the pivotal industry segment for electricity restructuring. Yet, little is known about the shape of transmission cost functions. Reasons for this can be a lack of consensus about the definition of transmission output and the complexitity of the relationship...

This paper addresses the timing of optimal investment in LPG pipelines when the goal is to maximize consumer surplus less private cost and social of transporting LPG.

Successful cap and trade programs for SO2 and NOx in the US allocate allowances to large emitters based on a historic base line for a period of up to thirty years. National Allocation Plans in Europe allocate CO2 allowances in an iterative approach first for a three then for a five-year period....
