Discussions on REMA: Splitting the Wholesale Market

In association with


Tuesday 26 September – 14:00 to 15:00

Part of  A Review of Electricity Market Arrangements (REMA)  series.

Following on from our first REMA seminar in May where we discussed Locational Marginal Pricing (LMP) we are holding a second seminar on Tuesday 26 September 2-3pm to discuss another of the Government’s proposed electricity market reforms – splitting the Wholesale Market in an aim to reduce the proportion of electricity sold for a gas-based price.

The seminar will be held by way of a discussion between our two guest speakers, Professor Michael Grubb and Professor Rob Gross, on how this could be achieved and the implications this would have for generators, suppliers and consumers. The discussion will be followed by a Question & Answer session.

Professor Michael Grubb

UCL Institute for Sustainable Resources / Professor of Energy and Climate Change

Michael Grubb is Professor of Energy and Climate Change at University College London (Institute of Sustainable Resources & Energy Institute), and Deputy Director for ISR. From 2011-2016, alongside academic roles, I worked half-time at the UK Office of Gas and Electricity Markets (the energy regulator, Ofgem) as Senior Advisor, initially on Sustainable Energy Policy, and subsequently Improving Regulation; from Autumn 2016 I moved to Chair the UK government’s Panel of Technical Experts on Electricity Market Reform.

In 2018 I was appointed as Convening Lead Author for Chapter 1 of the IPCC Sixth Assessment (Mitigation Report), and as leader for the Sustainability hub of the UK Research Council’s programme on Rebuilding Macroeconomics.

I have combined research and applied roles for many years, bringing research insights into policymaking, and bringing practical experience to bear upon academic studies. Before joining UCL I was part-time Senior Research Associate in Economics at Cambridge University, combined with (prior to joining Ofgem) Chief Economist at the Carbon Trust, and Chair of the international research network/interface organisation Climate Strategies.

These conjoined appointments followed 10 years at Chatham House where I led the Energy and Environment programme. I founded the Climate Policy journal and remained Editor-in-Chief until 2016. From 2008-11 I served on the UK Climate Change Committee, established under the UK Climate Change Act to advise the government on future carbon budgets and to report to Parliament on their implementation.

Author of eight books, sixty journal research articles, and numerous other publications.  The book Planetary Economics: energy, climate change and the Three Domains of Sustainable Development (Routledge 2014), brought together insights from 25 years of research and implementation of energy and climate policies.

Beyond energy and climate change, I am on the Scientific Advisory Boards of the German Inst for Economic Research (DIW Berlin).
