Much of the growth in renewable generation in GB is taking place locally at the distribution network level. Distributed generation has doubled over the last 5 years and now represents over a quarter of total GB capacity. This growth in distributed generation has the potential to transform the current market structure of electricity trading and introduce new markets and services, as well as new market participants. One new innovative market model approach is the local energy market (LEM) approach. The concept of the LEM is to establish a marketplace which draws together a community of renewable energy and low carbon generators, storage and demand side response providers at both the domestic and non-domestic level. Through the marketplace these providers can then participate in energy trading; entering both traditional and new market services.
