The Micro DE project was a scoping and feasibility study to identify opportunities for micro-generation storage and control technology development at an individual dwelling level in the UK.The study investigated the potential for reducing energy consumption and CO2 emissions through Distributed Energy (DE) technologies. This was achieved through the development of a segmented model of the UK housing stock supplemented with detailed, real-time supply and demand energy-usage gathered from field trials of micro distributed generation and storage technology in conjunction with building control systems.The outputs of this project now feed into the Smart Systems and Heat programme.This deliverable is number 7 of 9 in Work Package 1. It provides a review of a range of existing scenarios relating to the UK energy and electricity system. Suitable scenarios are needed forthe ETI Micro DE project to provide a framework to explore a number of technical questions relating to how the UK energy systems could perform with the introduction of the DE technologies studied within the project.The report recommends that the UKERC Energy 2050 scenarios are the most appropriate to use as a framework within the ETI Micro DE project
