“…Furthermore, as the share of intermittent renewable energy achieves higher levels in electricity systems, policies are evolving to account for the full system level costs incurred by intermittent renewables as opposed to just levelized costs of electricity (LCOEs), which often are calculated without consideration of wider system impacts. System level assessments are geographically specific and bring an important understanding of the true lifecycle costs of intermittent renewable energy [24,25]. In fact, system level considerations are leading to Net metering Access-based Pegged to the retail electricity rate System output offsets retail electricity purchases and excess generation can be applied as a credit to future electricity purchases the convergence of electricity tariff and renewable energy policy design as the adoption of distributed renewables is increasingly impacting electricity system costs as well as the distribution of expenses among electricity market ratepayers [26].…”

Policies to support the deployment of renewable energy technologies have been widely established for power generation, heating, cooling, and transportation. However, as renewable energy technologies have become increasingly cost-competitive and more widely deployed, policymakers have begun to focus their attention on the adaption of existing policies to reflect the rapidly changing economics of these technologies and the impacts they have may have on the energy systems in which they are deployed. Optimal renewable energy policies moving forward must, therefore, be context specific and tailored to the unique political, economic and social circumstances of the regional, national or sub-national energy systems in which they are to be applied. The Gulf Cooperation Council (GCC) is a region where each member country has stated ambitions and targets for renewable energy but deployment to date has been minimal. Therefore, GCC ambitions must be translated into actions via defined policies and regulations that reflect regional context, and thus have the highest likelihood of achieving success. This paper investigates current trends in renewable energy policy with the aim of identifying those that will be the most effective and feasible to catalyze renewable energy in GCC countries. The findings show that utility-scale renewable energy auctions are a primary mode of stimulating renewable energy deployment internationally and this mechanism is optimally aligned with catalyzing renewable energy deployment in the GCC countries. However, further evolution of regionally tailored renewable energy policy will be required as auction mechanisms gain traction and renewable energy becomes increasingly prominent.

“…The establishment of a professional benchmark for thorium nuclear reactors with only a few free parameters for a parametric study will significantly increase the reliability of such an analysis. Moreover, a comparative analysis with other generators, such as fossil fuels and renewables, will help to define the position of nuclear electricity in the energy mix for the selected region (Khatib & Difiglio 2016). The study shows the basic environmental problems related to the nuclear fuel cycle, which could Modelling of the reactor cycle cost for thorium-fuelled PWR and environmental aspects of a nuclear fuel cycle be elaborated in detail in future analysis.…”

The paper presents the methodology applied to the cost modelling of the uranium-thorium nuclear reactor cycle for PWR reactors as well as brief introduction to the environmental impact of the nuclear fuel cycle. The reactor core contains seed uranium fuel and blanket thorium fuel. In such a cycle, energy is produced in the fission of 235 U included in the fresh fuel and in the fission of 233 U bread from the fertile 232 Th. A modified methodology developed by the OECD Nuclear Energy Agency was used for the reactor cycle cost modelling. The method is based on the levelized lifetime cost methodology for a reactor cycle, which is directly related to the heavy metal mass balance. Contrary to the case of uranium-fuelled nuclear reactors, the cost modelling includes the additional cash flow for thorium fuel. The abundance of thorium in the Earth's crust is about 3-5 times larger than that of uranium, which suggests its promising potential as a nuclear fuel. However, this needs to be proved economically.

Although technical potential and costs reduction are beneficial for these technologies to find prominence in the system, research has shown that there is an optimal deployment level for both wind and PV given their variability and uncertainty [10,11,33,35].…”

“…The third reason for exclusion of distribution and transmission grids in long-term planning is that all technologies will increase integration costs. For the centralised system, these are mainly grid-related costs [40] and contingency reserve costs [127]. While this is true that every technology induces some integration costs, the variabilities of PV and wind introduce additional costs called profile costs and intermittency introduces another type of cost called the balancing costs on top of grid costs.…”

It is an undeniable fact that energy systems all over the world are at the point of a paradigm shift as a need for decarbonisation is eminent and unavoidable. The pressure to decarbonise mounts year after year. Since two thirds of all anthropogenic greenhouse-gas emissions come from the energy sector, decarbonisation is more about reducing emissions in the energy system than any other system in the world. The increased need for decarbonisation has resulted in the increased installation of photovoltaic (PV) and wind systems in countries such as China,
