Abstrakt: The German electricity market has been faced with growing volumes of investment in renewable energy sources (RES) in the recent years. In this paper, we evaluate the correlation between the variable RES generation and electricity consumption in the German electricity market. Capacity credit of RES measure the correlation between RES generation and peak load and it is an indicator to evaluate the contribution of RES to the generation resource adequacy as well. Results show that the capacity credit of variable RES in the German market and in the presence of a 20% share of variable renewables in the generation profile in 2012 is estimated to be approximately 4% of their installed capacity. By increasing the renewables penetration in the market, the capacity credit of variable RES is decreasing. The capacity credit of variable RES drops to 2.3% when these have a 50% share of the generation profile in the German market. [ABSTRACT FROM AUTHOR]
