| Summary: | The reform of a one player power sector (i.e. a natural monopoly) into a
multiple players’ power market brings to the clients not only the benefits of competition
but also the costs of complexity. In between the two, an optimal number of players is
found in the market corresponding to the minimum price of power to the clients.
Considering time as the third dimension, the optimum curve becomes a potential surface
on which the evolution of the market entities is seen as oscillations along the valley of
minimum price. Every oscillation triggers a price burst which is detrimental to the
clients. To avoid this, the role of the regulator is better defined in the sense of smoothing
the transition from monopoly to market. The example of the US power sector evolution is
relevant here. In the above approach long range competition resulting from the future
opening of power markets in Europe, or from the penetration, 70 years ago, of the
interconnection technology in USA, is compared with the short range (local) competition.
Finally, the price limits are determined which ensure that (i) the new entrants on the market are not eliminated and, (ii) that the market avoids oscillations which may
drastically shock a non-resilient economy. A case study calculation is done for Romania
and a method is proposed where the cost of complexity is assessed based on the ratio of
traded energy to consumed one i.e. more traded energy means that the price increases
with every transaction that is not bringing the energy to the consumer but to other
traders. An example Is presented for the present open market of Romania. |
