Abstract:
This paper suggests an innovative idea to examine the functionality of an intraday electricity market by testing causality among its fundamental components. Using Danish and Nordic data, it investigates the main drivers of the price difference between the intraday and day-ahead markets, and causality between wind forecast errors and their counterparts. Our results show that the wind and conventional generation forecast errors significantly cause the intraday price to differ from the day-ahead price, and that the relative intraday price decreases with the unexpected amount of wind generation. Cross-border electricity exchanges are found to be important to handle wind forecast errors. Additionally, some zonal differences with respect to both causality and impulse responses are detected. This paper provides the first evidence on the persuasive functioning of the intraday market in the case of Denmark, whereby intermittent production deviations are effectively reduced, and wind forecast errors are jointly handled through the responses from demand, conventional generation, and intraday international electricity trade.



Cooperate or Compete? Insights from Simulating a Global Oil Market with No Residual Supplier

Abstract:
Structural changes in the oil market, such as the rise of tight oil, are impacting conventional market dynamics and incentives for producers to cooperate. What if OPEC stopped organizing residual production collectively? We develop an equilibrium model to simulate a competitive world oil market from 2020 to 2030. It includes detailed conventional and unconventional oil supplies and financial investment constraints. Our competitive market scenarios indicate that oil prices first decline and tend to recover to reference residual supplier scenario levels by 2030. In a competitive oil market, a reduction in the financial resources made available to the global upstream oil sector leads to increased revenues for low-cost producers such as Saudi Arabia. Compared to the competitive scenario, Saudi Arabia does not benefit from acting alone as a residual supplier, but, under some assumptions, it benefits from being part of a larger group that works collectively as a residual supplier.
