Providing feedback to the UK government’s proposed changes to electricity markets, RAP arranged for Chris Neme of Energy Futures Group and Paul Peterson of Synapse Energy Economics to present at this workshop organized by demand resource providers (the “D3 Expert Stakeholder Workshop”: demand reduction, demand response and distributed generation) in London. They reviewed lessons learned when the US opened up markets to allow efficiency and other demand resources to compete with supply alternatives. They concluded that demand resources can compete, be as reliable as supply alternatives, and make significant contributions to meeting consumers’ and the grid’s needs.
