Abstract-The United Kingdom Government recently published a package of measures which would support investment in low-carbon technologies in the years up to 2020.It has also taken account of the highly uncertain investment conditions relating to the period beyond 2020, which threaten to undermine the 2014 Electricity Market Reform measures and deliver bad value. The CFD scheme under the Energy Act 2013 should provide a stable revenue level which should, in turn, reduce investment risks and financing costs, and so drive innovation and development of low-carbon technologies. The scheme can also cap the support costs for consumers when electricity prices are high. Concerns about the impact of CFD allocation policies on the solar industry can be addressed. This paper indicates that there is a clear benefit in committing to invest in low-carbon generation technologies to 2020, and beyond to the 2030s.The Government should state clearly that it intends to support investments in low-carbon technologies through the 2020s.Index Terms-Renewable obligation, energy solar power, CFD.

Impact of flexible bioenergy provision on residual load fluctuation: a case study for the TransnetBW transmission system in 2022

et al. 2017

Background: The transition towards a renewable based power system in Germany largely depends on variable renewable energy sources (vRES) like wind power and solar PV. Their high variability over time poses new challenges for power system stability. Bioenergy as a renewable source has already been established in recent years and has the capability to offset fluctuations from wind and solar PV and can therefore play a new role in coming years. Methods: This paper describes how existing bioenergy plants can be operated in order to offset fluctuations in power systems, performing a power system modelling based on time series data. As sample transmission system (TS), TransnetBW has been chosen, one of the four German transmission systems. We modelled two different types of bioenergy plant clusters, one including solid biomass plants and the other cluster covering biogas plants and other plants with comparable characteristics. For the modelling of the operation of these clusters, we used registered time series of the years 2011 and 2012 for a total load and feed-in from wind and solar PV, which were projected for the year 2022. The flexible bioenergy clusters are operated in order to minimize fluctuations in residual load (RL). This approach served as the basis to assess how concepts for flexible bioenergy provision can contribute to the task of balancing future power systems based on vRES. Results: Bioenergy plays an important role in the renewable power supply of the TransnetBW TS, as it holds a share of 23.3% among the renewables projected for 2022. A flexible bioenergy (BE) provision allows for a reduction in daily residual load fluctuations by 30% compared to the non-flexible power generation from BE. Flexible BE effectively offsets high fluctuations originated from the feed-in of the substantial solar PV installations in the TS and also contributes to serve the peak load. But in contrast to regions with higher renewable shares from vRES, the amount of avoided BE power production in times of negative RL (excess power from renewables) is still negligible for the 2022 time frame investigated and thus reducing the immanent requirement for flexible BE. Conclusions: In line with existing studies, the results show that bioenergy is already a valuable asset to achieve the targeted REN shares and can support the integration of the large vRES capacities in coming years, if produced flexibly. Operating biomass installations in a flexible manner effectively reduce daily fluctuations in RL, allow for a better integration of vRES and contribute to cover peak power demand. But from the findings of this case study, we conclude that the focus in the near-term should be on the efficient utilization of BE as the top priority until the demand for flexible BE provision is progressively increased with rising shares of vRES. Giving the regional differences, it should be stressed that the regional context, the relative share of wind and solar PV in the power system and therefore the investigated time horizon are important for ...

“…Furthermore, transmission grid expansion is the cheapest way to integrate high shares of renewables and makes the power system more resilient (Ecofys 2013). Finally, in the light of the growing generation from scattered and intermittent RES, grid management faces new challenges such as unplanned energy flows (Spiecker and Weber, 2014), and interconnectors are one of the necessary components of achieving efficiency (Neuhoff et al, 2011). Finally, a case study of a Japan-Korea interconnector reveals significant costeffectiveness of interconnection and increased efficiency of the regional decarbonisation strategies compared to individual efforts.…”

Terms of use: Documents in AbstractThe common European electricity market requires both market integration and transmission grid expansion, including trans-border interconnectors. Although the benefits of increased interconnectivity are widely acknowledged, expansion of interconnectors is often very slow.This paper gathers insights on the reasons behind this "grid-lock" drawing on the study of the German-Polish border. Although two interconnectors already exist, the trade is blocked by unplanned electricity loop flows. A third interconnector has been discussed for years, but saw little progress in spite of declarations of support on both sides. Drawing on the existing literature on the topic of grid expansion we identify four hypotheses for the grid-lock: inadequate financing; diverging interests; governance and administration problems; and different actors' motivations, trust and security perceptions. We evaluate them using the empirical material gathered through document analysis and stakeholder interviews conducted in Germany and Poland. None of the hypotheses on its own can explain the "gridlock". However, while financing has not been a major obstacle, divergent interests had an impact on the project delay, administrative and governance problems are a great hindrance on the technical level, while motivations influence interstate political relations and policy shaping. EU support and closer bilateral cooperation provide opportunities to address these challenges.
