Comillas Regulatory Roadmap for Distribution Remuneration (IIT WP, 2026)

M.A. Ruiz, T. Gómez and J.P. Chaves, “A regulatory roadmap for electricity distribution remuneration under decarbonization: A European perspective”, IIT working paper IIT-26-103WP, registered 15 April 2026. This page rests on the abstract only: the IIT catalogue page gives the abstract and citation but no download, so the full working paper was not obtained. The companion journal article (Ruiz, Gómez and Chaves-Avila, International Journal of Electrical Power & Energy Systems, 2026) could not be fetched either, since the publisher and repository block automated access; a maintainer copy in Raw/ would allow a full check. The Source - ISGAN BRIDGE Distribution Remuneration and Flexibility (2026) is the joint paper that applies this roadmap.

The roadmap in the abstract

The paper proposes a regulatory roadmap for reforming electricity distribution remuneration in Europe, with priorities ordered by potential impact, and argues that combining grid investment with smart-grid solutions at least cost depends on the incentives embedded in the remuneration scheme:

1. Move from cost-of-service or hybrid approaches to revenue-cap or price-cap regulation, for productive efficiency.
2. Decouple the ex-ante revenue or price calculation from the company’s investment plans, to reduce allocative inefficiency.
3. Promote efficient plans by enabling adaptable planning.
4. Establish neutral OPEX/CAPEX incentives by giving OPEX and CAPEX different incentives, presented as a novel alternative to the fixed capitalisation rate.

The first two steps are called urgent in the decarbonisation context; the third could deliver significant savings if the first two are handled well. The abstract states the roadmap is validated by prior experience in a selection of representative European jurisdictions, which it does not name.

Relevance

The same four steps, in the same order, are the BeFlexible roadmap summarised in the Source - ISGAN BRIDGE Distribution Remuneration and Flexibility (2026). For Sweden the relevant pages are RP5 Revenue Cap Methodology (2028–2031) and the tariff reform. Nothing here addresses Sweden specifically.
