Question
To ask the Secretary of State for Transport, pursuant to the Answer of 2 November 2026 to Question 38365, whether her Department has provided the Department for Energy Security and Net Zero with electricity price forecasts for use in its modelling of the
Answer
Future energy price forecasts as produced by DESNZ, such as the supplementary guidance to the Green Book, are used by DfT to estimate the future costs of ownership for electric HGVs. These can be found here: https://www.gov.uk/government/publications/valuation-of-energy-use-and-greenhouse-gas-emissions-for-appraisal.
Verdict: RED (12/100)
The reply does not answer the question that was asked. The question was whether the Department for Transport provided electricity price forecasts to DESNZ, but the response describes the reverse: DfT using DESNZ's published forecasts in its electric HGV cost modelling. It never says whether DfT supplied anything to DESNZ, and it only refers the reader to a DESNZ publication, so the person who asked would likely need to submit a follow-up.

It touches the same subject area and points to a DESNZ publication, but it does not answer the direction of the question asked. |
