Can Merchant Interconnectors Deliver Lower and More Stable Prices? The Case of NorNed

EPRG 0926 Non-Technical Summary | PDF

Abstract: This paper estimates the effect of the merchant interconnector between Norway and the Netherlands on the level and residual volatility of hourly day-ahead electricity prices in the two connected markets. The price effects are estimated using single equation ARMA models and the volatility effects are estimated using EGARCH models with multiplicative heteroskedasticity. Both the level and volatility effects on prices are found to be modest. This result implies that the majority of welfare gains resulting from trade across the interconnector are likely to be accrued to its owners, undermining the practical validity of the theoretical argument that lumpiness in transmission investment leads to a divergence between social and private benefits of transmission investment. This paper finds that, on the scale of NorNed, there is little evidence to suggest that transmission capacity between different markets cannot be provided competitively.
