Measure renewable capture value

Renewable output is correlated with weather and other generators. Revenue depends on the generation-weighted price, not just the time-average price. Losses, curtailment, degradation and contracts require explicit treatment.

Working relationship

Capture price = Σ generated MWh × price / Σ generated MWh

What to keep separate

A high capacity factor does not guarantee a high capture price or bankable cash flow.

Your task

Calculate capture price before and after a curtailment assumption, then compare solar and wind profiles.

Key terms in plain English
MWh
Megawatt-hour: a quantity of energy. A steady 1 MW for one hour delivers 1 MWh.
Curtailment
A reduction in generation below what could otherwise have been produced. Network limits, system security and commercial decisions can have different causes.
