| Summary/Abstract |
The current transformation of energy systems around the world is fundamentally a policy-driven process, unlike previous socio-technical transitions. This article focuses on the challenges of constructing forward-looking policies for sustainable energy transitions in the presence of powerful incumbent interests, through an in-depth study of how the emerging option of demand-side response (DSR) was incorporated into the Capacity Market (CM) for electricity in Great Britain over the period 2010 to 2014. Drawing on extensive documentation related to the development of the CM rules and interviews with participants and close observers of the process, the paper provides an unusually detailed assessment of the influence of companies with large electricity generation assets. The evidence presented supports the hypotheses that these companies had influence through deploying public facing strategies, that they had been able to draw on close networks of contacts and networks with senior policy makers, and that the latter had internalised the ideas and interests of the former. Despite counter-lobbying by DSR firms and non-governmental organisations, institutional arrangements gave major generators an advantage in terms of access. The paper concludes by recommending the establishment of independent bodies to propose policies and monitor the process of their development during energy system transformations.

| Summary/Abstract |
In actual energy-only markets, the high volatility of power prices affects the expected returns of generators. When dealing with irreversibility under uncertainty, deferring decisions to commit in new power plants, waiting for better information, is therefore a rational approach. Theoretical and empirical evidence suggests that such investment pattern determines the occurrence of construction cycles, which strongly compromise supply security. In order to supplement generators' revenues, several remuneration mechanisms have been devised over past years. Along this line, this work addresses the long-run dynamics of capacity adequacy and market efficiency with both a price-based and a quantity-based capacity remuneration policy. For that purpose, a recently-developed, stochastic simulation model is used as a benchmark. Hence, the optimal postponement of generation investment decisions is integrated into a long-run power market model by formulating the decision-making problem in the framework of Real Options Analysis. Results suggest that policymakers may exchange supply security (effectiveness) for energy prices to be paid by consumers (efficiency) when designing and implementing capacity remuneration mechanisms. By doing so, this article contributes to the ongoing debate regarding the design of incentive policies and efficient power markets by considering the microeconomics of investors’ decision-making under irreversibility and uncertainty.

| Summary/Abstract |
Most existing support schemes aim to stimulate the deployment of renewable energy sources in the electricity sector on the basis of the electricity output (MW h) of renewable energy installations. Support is anchored in the electricity commodity market. In contrast to this established approach, Russia intends to promote renewable energy through the capacity market. The idea is to remunerate investors for the installed capacity (MW) of their installations, in particular for the availability of their installations to produce electricity. This article argues that, contrary to the implicit consensus, a capacity-based approach to supporting renewable energy can provide an alternative to the current output-based schemes. Capacity-based schemes limit the incentive that the operators of renewable energy installations currently have under output-based schemes to deliver electricity to the grid even in periods of low demand. These schemes also provide investors with a more predictable income flow. However, to be successful, the regulation of capacity supply - currently designed for flexible power plants - needs to accommodate the specific production patterns of variable renewable energy installations. This paper examines ways to overcome this challenge in Russia and provides more general conclusions on the complex interaction between capacity markets and renewable energy investments.
