By combining Wood Mackenzie’s historic modelled generation for wind and solar power plants (read more about modelled generation here) with historical nodal pricing, generation-weighted pricing is now available for select power plants.
To access this data, filter to a power plant that has both modelled generation data and historical power price data. In the Lens UI, go to the Prices dashboard where you can view historic modelled capture prices in the ‘Power prices by settlement point’ chart in the ‘Historic modelled capture price’ dataset. Generation-weighted basis is also available in the basis chart.
Three different curtailment scenarios are available to select:
No curtailment: Assumes that generation is not affected by nodal price.
Price < $0: Assigns a value of 0 to generation for all hours where the nodal price is less than $0.
Price < $-26 (PTC): Assigns a value of 0 to generation for all hours where the nodal price is less than -$26.
This data is also available in Lens Direct at the hourly, monthly, and annual levels.
Annual data is calculated by the summation of the products of price and generation across all hours in that year, divided by the total generation in that year.
