“…Table 11 shows the different costs and ramping efficiencies of the power plants based on our rough estimations. We note that wind, solar, and nuclear production cannot be up-or down-reserved and that lignite and coal plants ramp-up relatively slowly, whereas gas-fired plants are characterized by flexibility (Gutiérrez-Martín et al, 2013).…”

“…Also, Ueckerdt et al (2015) show that gas-fired plants are required when short-term variability of renewables is introduced into a long-term German power system model with an 80% emission reduction target. Indeed, gas-fired plants have lower CO 2 emissions and higher fuel efficiency than coal plants (Gutiérrez-Martín et al, 2013). However, major utilities in the UK, France, Germany, and Italy, among others, have recently closed or mothballed gas-fired power plants in response to low profitability (Caldecott and McDaniels, 2014).…”

The large-scale deployment of intermittent renewable energy sources may cause substantial power imbalance. Together with the transmission grid congestion caused by the remoteness of these sources from load centers, this creates a need for fast-adjusting conventional capacity such as gas-fired plants. However, these plants have become unprofitable because of lower power prices due to the zero marginal costs of renewables. Consequently, policymakers are proposing new measures for mitigating balancing costs and securing supply. In this paper, we take the perspective of the regulator to assess the effectiveness of support payments to flexible generators. Using data on the German power system, we implement a bi-level programming model, which shows that such payments for gas-fired plants in southern Germany reduce balancing costs and can be used as part of policy to integrate renewable energy.

“…Regarding the cost side, only policy support costs have been taken into account and not system generation costs, which would be needed for a cost-benefit analysis. The costs for the electricity system related to the variable character and the limited predictability of the generation of electricity from intermittent RES-E (usually called cycling costs and balancing costs) have not been included because their values compared to other impacts are negligible with low RES-E penetration levels, as argue [5] and [14].…”

The large increase in renewable energy sources (RES-E) penetration in the European Union (EU) has raised the concern of policy makers about the costs of public promotion of RES-E, in spite of the commitment of the European Commission to the deployment of RES-E in the last years. This paper is focused on wind energy, because it is the renewable technology with the highest contribution to electricity mix in Europe (excluding hydro). An economic analysis of wind energy contribution should not only take into account the policy costs of the deployment, which are finally paid by electricity consumers, but also its benefits, particularly those related to climate change mitigation and the reduction of fossil fuel dependence distributed among citizens. The aim of this paper is to fill this gap and evaluate the policy costs and the most relevant benefits of wind energy deployment in the EU28 (28 Member States) using 2013 data. For this purpose, an innovated methodology internationally validated has been used. The results show that the benefits considered are relevant and should be taken into account when support costs are assessed and in the future development of energy policies in Europe.

Environmental problems related to the conventional generators have motivated governmental policies all over the world in order to incorporate alternative power sources to reduce greenhouse gas (GHG) emissions and fossil-fuel consumption. On the one hand, wind power generation can increase GHG emissions of the others conventional generators connected to the system. On the other hand, wind energy is characterized by its variability that imposes challenges in the operation of the power system. In order to integrate GHG emissions estimation and the uncertainty related to the wind power generation, a probabilistic point of view is presented in this paper to estimate the probability distribution function (PDF) of the GHG emissions of a typical insular power system. The PDF of power production of each conventional generator is calculated, and then the expected value of the total GHG emissions is estimated.
