Off the books, onto the bills: levy-backed derisking and the UK’s green transition

What explains the United Kingdom’s relative success in mobilizing private capital for high‑risk, low‑carbon infrastructure? This paper argues that the answer is levy‑backed derisking: a green macro‑financial regime that channels system‑level risks into standardized, levy‑funded revenue streams administered by arm’s‑length counterparties. Examining Contracts for Difference, the Capacity Market, nuclear Regulated Asset Base financing and anticipatory transmission investment, it shows how the UK has built an integrated ‘settlement spine’ that converts uncertain technical outcomes into predictable cash flows and shifts cost recovery from Treasury budgets to consumer energy bills. The core contribution is to conceptualize levy‑backed derisking as depoliticization by design, arguing that the very features which make the regime investable systematically displace distributional conflict from parliamentary visibility into technocratic forums. Two further implications follow. First, the distributional profile of the UK’s Green Transition yields a three-way asymmetry: privatized financial returns to investors, diffuse public goods to society and regressively socialized costs to consumers. Second, this asymmetry deepens as the regime expands, since the extension from renewables to capacity adequacy, nuclear construction and anticipatory grid building progressively loosens ex ante constraints on consumer bill exposure, calling into question the political durability of levy‑backed derisking under conditions of mounting bill stress.
