As renewables take a growing share of the generation mix, their effect on price formation and volatility is increasingly what drives market outcomes. We have brought the metrics that capture this into a dedicated Renewables economics tab in the power workspace, computed from our existing price, generation, and load data.
Capture rate
The Capture rate widget displays the volume-weighted average price earned by solar, wind onshore, and wind offshore over a defined period, and that price relative to the market average. With a high capture rate, generation lands in high-price hours, while a low capture rate points to oversupply, weak demand, or curtailment. There is also the option to set the 'Price lower bound', ranging from -5 to +5, setting the minimum price (in €/MWh) to include in capture price and capture rate computations. As a result, prices greater than or equal to this value are included.
This widget has the option to display the Capture rate or Capture price alone, or together. Capture prices are also available via API: /power/prices/capture
Cumulative negative price & residual demand hours
The Cumulative negative price & residual demand hours (cumulative negative hours per year) widget displays where and how often oversupply is showing up, with year-on-year comparison to make the trend visible. The toggle in the top-right of the chart lets you choose between graphing the price or the residual demand.
Renewables penetration
The Renewables penetration widget displays the share of demand covered by renewable generation, broken down by fuel type. The visual is split in two, with one for Total Demand and one for Total Generation.
All metrics are available per country or bidding zone, daily, weekly, monthly, quarterly, or yearly granularity. The YoY toggle can be enabled after selecting only one location and one fuel type to enable year-on-year seasonal view. We have also made efforts to significantly reduce the tab's load time.
