Abstract
Merchant electricity transmission investment is a practically relevant example of an unregulated investment with monopoly properties However while leaving the investment decision to the market the regulator may decide to prohibit capacity withholding with a mustoffer provision This paper examines the welfare effects of a mustoffer provision prior to the capacity choice given three reasons for capacity withholding uncertainty demand growth and preemptive investment A mustoffer provision will decrease welfare in the first two cases and can enhance welfare only in the last case In the presence of importer market power a regulatory test might be needed
