Article publication « Photovoltaic and wind power feed-in impact on electricity prices: The case of Germany » by François Benhmad and Jacques Percebois in Energy Policy review.
The aim of the paper is to quantify the impact of increasing renewable energy sources (RES), especially wind generation and photovoltaic feed-in, on electricity prices in Germany, with a view to investigating the well-known merit order effect.
To explore the dynamics of the merit order effect at an hourly resolution, we use the SURE methodology for carrying out an empirical analysis based on hourly historical data for the Germany electricity market between 2012 and 2015.
Our main empirical findings confirm that increasing the share of wind generation and photovoltaic feed-in induces a sharp fall in electricity spot prices. Moreover, this impact varies throughout the 24 h of the day due to the dynamics of electricity demand and the intermittency of wind and solar photovoltaic feed-in.
