ABSTRACT

Investments in cross-border electricity interconnections are key for the integration of the European energy market. To analyze policy frameworks for these decisions, we model two settings for the expansion of transmission capacity between two regions, where the volume of investment is agreed upon through either NashCoase or Nash bargaining. For each setting we provide fair share cost allocation solutions, respectively with and without compensations. Each region has its own TSO, maximizing social welfare within its geography, and the markets are modeled with linear supply and demand curves, with trade enabled by the interconnection. The results of the application of the models to the Iberian market suggest their ability to estimate realistic values for the capacity of cross-border interconnection between two regions.

5. Conclusions

In this paper we present an interconnection investment model that considers bargaining between market coupled regions, together with solutions for fair share cost allocation of investment costs in settings with and without compensations.

With a case study to the Iberian Peninsula, using market data of 2013, we show different patterns of cost allocation, depending on transmission investment costs. At very low costs, the importing country (Portugal) fully supports the investment and if allowed would provide an economic compensation to the exporting country (Spain). As the costs increase, the allocation switches from the importing country to the exporting country. In both models, an increase in the overall social welfare comes at the expense of the consumers from the exporting region, who will pay a higher price for electricity, and the producers of the importing country, who may have difficulty in dispatching their most expensive generators. Policy makers must be aware of these tradeoffs.

The results of the I-TEP-MCR models suggest their ability to estimate realistic values for cross-border interconnection investments between two regions. In the case of the Iberian market, the results are in the 3000 to 4000 MW interconnection capacity range, when compensations are allowed, and up to 3100 MW when these are restricted. Both these results nevertheless contain the projected value for 2016.

Iberia is currently one of the few “electric peninsulas” in Europe [3], and the interconnection between Spain and France may be one of the interconnections to deserve a larger expansion, to allow the European market to take advantage of the high electricity export capacity in Iberia, enabled by the recent investments in renewable energy. If both parties, Iberia and France, were to benefit from the expansion of the interconnection between Spain and France, a solution through bargaining would come naturally.
