The participation of household prosumers in wholesale electricity markets is very limited, considering the minimum participation limit imposed by most market participation rules. The generation capacity of households has been increasing since the installation of distributed generation from renewable sources in their facilities brings advantages for themselves and the system. Due to the growth of self-consumption, network operators have been putting aside the purchase of electricity from households, and there has been a reduction in the price of these transactions. This paper proposes an innovative model that uses the aggregation of households to reach the minimum limits of electricity volume needed to participate in the wholesale market. In this way, the Aggregator represents the community of households in market sales and purchases. An electricity transactions portfolio optimization model is proposed to enable the Aggregator reaching the decisions on which markets to participate to maximize the market negotiation outcomes, considering the day-ahead market, intra-day market, and retail market. A case study is presented, considering the Iberian wholesale electricity market and the Portuguese retail market. A community of 50 prosumers equipped with photovoltaic generators and individual storage systems is used to carry out the experiments. A cost reduction of 6–11% is achieved when the community of households buys and sells electricity in the wholesale market through the Aggregator.

Shaun McRae of the University of Michigan reviews “The Economics of Electricity Markets: Theory and Policy”, by Pippo Ranci and Guido Cervigni. The Econlit abstract of this book begins: “Six papers address the main issues that arise when competition is introduced into the electricity industry. Papers discuss wholesale electricity markets (Guido Cervigni and Dmitri Perekhodtsev); generation capacity adequacy (Cervigni, Andrea Commisso, and Perekhodtsev); congestion management and transmission rights (Perekhodtsev and Cervigni); competition policy in the electricity industry (Cervigni and Perekhodtsev); retail competition (Anna Creti and Clara Poletti); and climate change and the future of the liberalized electricity markets (Cervigni). Ranci is Professor of Economic Policy at the Catholic University of Milan and Chair of the Board of Appeal of the European Agency for the Cooperation of Energy Regulators. Cervigni is Research Director at the Center for Research on Energy and Environmental Economics and Policy at Bocconi University and Chief Economist at A2A S.p.A. Index.”
