India has made great progress in reaching its ambitious goal to scale up renewable energy capacity to 175 GW in 2022. Solar power plays a central part in achieving this goal and installations of utility scale power have seen a dramatic increase in the last few years. Rooftop solar, however, is...

In this paper we present and discuss the results of an expert elicitation survey on solar technologies. Sixteen leading European experts from the academic world, the private sector and international institutions took part in this expert elicitation survey on Photovoltaic (PV) and Concentrated...

Optimal R&D investment is defined by deep uncertainty that can only partially be addressed through historical data. Thus, expert judgments expressed as subjective probability distributions are seen as an alternative way of assessing the potential of new technologies. In this paper we propose a...

Over the past three years Italy has witnessed a rapid growth in the photovoltaic energy market, followed by an equally sudden decline when the government decided to reduce the incentives. This sharp change in the trend of the market calls into question the achievement of Grid Parity and the...

This study seeks to provide a clear and comprehensive overview on the various aspects related to the current status and the future prospects of renewable energy (namely solar and wind) in Southern and Eastern Mediterranean countries (SEMCs). In order to do so, the study will first provide a...

Control power (regulating power, balancing power) is used to quickly restore the supply-demand balance in power systems. Variable renewable energy sources (VRE) such as wind and solar power are often thought to increase the reserve requirement significantly. This paper provides a comprehensive...

This paper estimates the welfare-optimal market share of wind and solar power, explicitly taking into account their output variability. We present a theoretical valuation framework that consistently accounts for output variability over time, forecast errors, and the location of generators in the...

The income that wind and solar power receive on the market is affected by the variability of their output. At times of high availability of the primary energy source, they supply electricity at zero marginal costs, shift the supply curve (merit-order curve) to the right and thereby reduce the...

We assess the optimality of investments in power grid innovation, under both technological options of Super and Smart Grids, using the WITCH model in the version that includes Super-Grids. Super Grids allow producing and trading of electricity generated by large scale concentrated solar power...

This paper provides a general characterization of overall power regulation and a detailed characterization of the ongoing evolution of distributed rooftop photovoltaic (PV) regulation in Costa Rica. The paper further develops rooftop PV adoption models for several classes of consumers and...
