Are Renewable Energy Sources (RES) Really Paid at 'High Prices'?

In the public debate regarding the competitive electricity market, it is often argued that Renewable Energy Sources (RES) are paid at high prices due to the wholesale price (MCP) determined by the most expensive production unit. However, this approach is incomplete, as it overlooks the crucial factor of revenue: the volume of energy cleared and compensated. A producer's income depends on the product of price and compensated energy. Therefore, high MCP prices do not necessarily mean that RES sell the bulk of their production at those prices. The correct metric is the production-weighted average price (capture price), which takes into account the volume of production at each price. RES production is concentrated during daylight hours with high solar radiation, where prices are lower due to the merit-order effect and cannibalisation. Data shows that the weighted average price for photovoltaics is lower than the simple average of MCP prices. Furthermore, curtailments in RES production due to system constraints further reduce revenues.
