Governance arrangements for electricity industries commonly claim the interests of consumers as their paramount objective. This would suggest a key decision making role for energy users, in all their diversity. However, the industry’s critical role in societal, welfare, large environmental impacts, and the challenges of ensuring it’s secure and reliable operation, all represent key shared…

Prosumage of solar electricity: pros, cons, and the system perspective
We examine the role of prosumage of solar electricity, i.e. PV self-generation combined with distributed storage, in the context of the low-carbon energy transformation. First, we devise a qualitative account of arguments in favor of and against prosumage. Second, we give an overview of prosumage in Germany. Prosumage will likely gain momentum as support payments…
Prosumage and the future regulation of utilities: An introduction
The objective of this EEEP symposium is to assess recent developments in prosumage- including technical and economic trends, the impacts of different regulatory settings, and their relationships to utility strategy and regulation in the light of recent trends-and to sketch out potential future pathways. The symposium brings together in-depth analyses of the prosumage phenomenon and…

An Option Analysis of the European Union Renewable Energy Support Mechanisms
We examine the economic efficiency of incentive mechanisms used to promote Renewable Energy (RE) across the European Union (EU) by looking at returns to investors along with any negative externalities or social costs. Using electricity price data from 2009 to 2013, we evaluate the RE support mechanisms adopted by some of the largest EU economies….
A regulatory framework for an evolving electricity sector: Highlights of the MIT utility of the future study
The electric power sector is once again evolving. A variety of distributed energy resources and improving computation, communication, and control technologies create an unprecedented degree of choice for electricity consumers, choices that are poorly guided by electricity rates and other incentives designed for a comparatively simpler era. These technologies also create new tools for regulated…
“Prosumage” and the British Electricity Market
Domestic electricity consumers with PV panels have become known as “prosumers”; some of them also have energy storage and we have named the combination “prosumage”. The challenges of renewable intermittency could be offset by storing power, and many engineering studies consider the role and value of storage which is properly integrated into the ‘smart grid’….
Balancing between competition and coordination in smart grids – a Common Information Platform (CIP)
The commercial value added in electricity distribution networks and smart grids is increasing. Concerns about competition on a level-playing field are raised. The debate on vertical network unbundling is reaching the distribution networks. Primary driver for this discussion is the requirement to exchange information in smart grids in a neutral and non-discriminatory way. Against the…
Performance Incentives in Capacity Mechanisms: Conceptual Considerations and Empirical Evidence
Performance incentives are elements of capacity mechanism design aimed at prompting committed agents to manage their resources in such a way that they eventually meet their obligations when the system is tight. These incentives can be introduced in practice by means of two different (but non-conflicting) approaches in capacity mechanisms. First, performance incentives can be…
Climate Policy with the Chequebook – An Economic Analysis of Climate Investment Support
Across the globe, climate policy is increasingly using investment support instruments, such as grants, concessional loans, and guarantees – whereas carbon prices are losing importance. This development substantially increases the risk of inefficient public spending. In this paper, we examine the ability of finance instruments to effectively and efficiently address market failures related to clean…
