The methodology utilizes a dual-Contract for Difference (CfD) model covering both electricity (CfDe) and carbon (CfDc), incorporating UK Government projected wholesale electricity prices and carbon market values. The analysis assumes a phased deployment of four units between 2030 and 2045, noting that costs remain uncertain due to a lack of commercial-scale power-BECCS projects.","ai_generated":true,"unit":"ember-000321#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"Ember has increased its estimate for the annual subsidies required per BECCS unit at Drax to an average of £591 million in 2023 prices, up from a January 2024 estimate of £425 million per unit.","ai_generated":true,"unit":"ember-000321#insight-1","date_modified":"2026-10-23"},{"text":"The subsidy calculation uses a dual-CfD mechanism consisting of a Contract for Difference for electricity (CfDe) and one for carbon (CfDc), each with its own Reference and Strike Price; carbon Transport & Storage (T&S) costs are excluded as they are expected to be handled outside the CfD.","ai_generated":true,"unit":"ember-000321#insight-2","date_modified":"2026-10-23"},{"text":"For the CfDe component, the Strike Price is set at £147/MWh (in 2023 prices), based on the 2027-31 large-scale biomass generators arrangements, while the Reference Price is based on the UK Government's projected mean wholesale price for baseload electricity from 2030 to 2050.","ai_generated":true,"unit":"ember-000321#insight-3","date_modified":"2026-10-23"},{"text":"For the CfDc component, the Strike Price is proxied using the UK Government's target maximum greenhouse gas removal price of £200 per tonne of CO2e, though other estimates suggest higher costs, such as the Climate Change Committee's estimate of £344 per tonne in 2030.","ai_generated":true,"unit":"ember-000321#insight-4","date_modified":"2026-10-23"},{"text":"The analysis assumes a deployment timeline where Drax converts one unit in 2030, a second in 2035, a third in 2040, and a fourth in 2045, although an accelerated timeline proposed by Drax could increase total subsidies between 2030 and 2050.","ai_generated":true,"unit":"ember-000321#insight-5","date_modified":"2026-10-23"}],"climate_tags":["bio-energy with carbon capture and storage","carbon capture and storage","climate finance","subsidy"],"geography_discussed":[],"frame_perspective":[],"analysis_type":["financial modeling","methodology update"]}]}
