Along with the efforts of the European Union to introduce third party
access (TPA) in the transmission of electricity, a new export market f
or Norwegian low-cost hydropower is being opened. Since the generation
of hydropower is environmentally clean (ie producing no emission of C
O2, SO2 etc), we would expect that Norwegian electricity could obtain
a premium under a common European system of environmental taxes as com
pared to electricity based on coal, oil and natural gas. In this paper
we set out to investigate the strategic position of Norwegian hydropo
wer and, in particular, to study optimal decisions with respect to the
installation of new export transmission lines. For this purpose, we c
onstruct an integrated long-run equilibrium model for the northern Eur
opean electricity market determining production, consumption and trade
.
