A grid's day, and what each kind of power earns for showing up when it does
Electricity is worth more at some hours than others. Solar all arrives at midday and drives the price down; gas waits for the evening peak and sells high. So on the same grid, in the same year, each technology captures a different day-ahead price; because their output occurs in different market hours. This is gross day-ahead market value, not production cost and not realised project revenue (PPAs, CfDs, balancing and hedging sit on top). Pick a grid and season to see it.
The price the market pays this source; not what it costs to generate. Length = capture price (generation-weighted day-ahead price) · width = share of reported zonal generation (imports not included) · area = proportional gross day-ahead value. The percentage after each price is the capture rate vs the time-weighted average. Sorted by capture price.
Dashed line = the flat 24/7 average price. A tall bar below the line produced mostly in low-price hours; the market is saturated with it in those hours. A thin bar above the line produced disproportionately in high-price hours; whether more of it would be economic depends on cost, utilisation and system constraints, which this page does not model.
Capture price is one layer of a siting decision. The siting screen combines it with EHV connection points, clean-firm capacity, queue congestion, water stress and counterparty ownership; in one graph traversal, with the receipt attached.
