This paper is about the reframing of electricity markets as a strategically oriented nonstate governance activity of intermediary organisations. In particular, it is centred on the establishment of ‘green’ electricity labels by environmental and other nongovernmental organisations (NGOs) as an attempt to establish and shape a market for green electricity. Such labels serve as a ‘boundary object’ between electricity generators, suppliers, consumers, and regulators, and are analysed as the creation of new sociotechnical arrangements around green electricity generation and use. The analysis also shows that private governance initiatives of this kind are highly interdependent with state regulatory systems. NGOs have played a vital role in defining and negotiating such standards, enrolling and aligning supply-side and demand-side actors, communicating with a wider public and building trust for the respective products, establishing links with regulators, and shaping policies for renewable electricity at national and European levels. The cases of electricity labelling investigated are an example of new political strategies of civil society intermediary organisations in an increasingly market-driven environment.

Although solar photovoltaic (PV) systems are environmentally friendly, policy makers and power system operators have concerns regarding the high penetration of these systems due to potential impacts of solar power intermittency on power systems. Understanding the nature of this intermittency is important to make informed decisions regarding solar power plants, size and location, transmission and distribution systems planning, as well as thermal generation units and electricity markets operations. This article presents a review of solar PV power characteristics and its impacts on power system operation.

As the utility grid evolves to transmit information along with energy and water to the end-user, the traditional grid model is changing. The Pecan Street Smart Grid Demonstration Project in Austin, TX is at the leading edge of the evolution of the smart grid. Currently, over 100 homes, soon to be 1,000, have electricity demand information being measured on a 15 second interval. Using the highly granular energy use and solar generation data from Pecan Street, we attempt to estimate the potential for small natural gas fuel cells as distributed firming power for intermittent renewables in the built environment. Micro-grids have traditionally relied on the macro-grid for stabilization in the event of local interruptions in generation. In this paper we analyze the utility, economic, and system efficiency impacts of small distributed natural gas fuel cells as an alternative to the macro-grid for stabilization. Using our unique dataset, we have determined that the average home could utilize a 5.5 kW fuel cell either for total generation or backup, and the average home could operate as its own micro-grid while not sacrificing core functionality. We also explore the utility of matching the thermal output of a possibly smaller fuel cell, used in combined heat and power mode (CHP), to an absorption refrigeration system in place of traditional space cooling. With these types of energy assets, homes could possibly participate with local electricity markets, or the grid at large, in a highly dynamic way. A home energy network could, given homeowner set-points, adjust home uses of energy and sell high priced electricity back to the grid, possibly from both solar PV and fuel cell production, possibly eliminating energy bills. Lastly, we estimate that the system efficiency could possibly double by transporting natural gas to the end user to be converted into electricity and hot water as compared with traditional methods of using natural gas for power generation followed by electricity delivery.
