Definition 5.7 Markets III: Commodities, Energy and Crypto · Chapitre 5 — Power Markets I: Design

The spark spread of a gas-fired plant of efficiency η\eta is the power price minus the price of the gas it burns per MWh of electricity, Ppower−Pgas/ηP_{\mathrm{power}} - P_{\mathrm{gas}}/\eta; the dark spread is the same for a coal-fired plant.

An illustrative merit order with 10 GW of wind and solar: gas at 35\, EUR/ MWh of fuel, coal at 12\,, lignite at 5\,, carbon at 70\, EUR/ t. At 45 GW of demand a combined-cycle gas plant sets the price (89.35\, EUR/ MWh); at 60 GW a coal plant does (89.68\,). Data: the chapter’s tutorial.
