Stakeholder Needs

To limit global warming to less than 2 °C requires a low-carbon transition with very large shares of renewables. Options such as wind, solar and hydro are influenced by both short and longer-term weather and climate variability. While still subject to natural and anthropogenic climate forcing and fluctuating energy prices, water reservoirs can dually operate as storage and production facilities and serve to balance the more volatile production capacity from solar and wind. This paper assesses the dynamics and demands of the hydro-dominated Nordic electricity system and market and identifies untapped potential for climate services based on a combination of literature-based research, documented stakeholder needs and data sources on historical and future conditions. A critical need for both improving the appropriateness and reliability of existing climate services and for developing new tailored solutions for a broader group of stakeholders from the renewable energy sector in the Nordics is observed. The quantification of uncertainties related to short-term weather forecasts and longer-term climate predictions is also found to be important for minimizing the financial risk in relation to systems management and to overall investments in renewable energy.

Containment Measures

Abstract The ongoing COVID-19 pandemic has presented us with an unprecedented global emergency that severely threatens the lives of millions of people around the world. In response to this existential crisis, state governments have taken drastic containment measures to limit the spread of the coronavirus. The consequential lock-downs have disrupted production and economic activity and had profound impacts on major industries. The heightened financial risk has significantly slowed down new investments while stoking fears of a looming economic recession. Indeed, the pandemic-induced strong reduction in global demand has resulted in sharp falls in energy prices leading to a temporary market distortion that may impede progress in the deployment of new renewable energy projects. Besides, some countries could be at risk of falling short of their 2020 national binding targets given the lack of effective policies required to facilitate new renewable energy investments. Considering the present impacts of the COVID-19 pandemic on the global energy market, there are opportunities to highlight the important role of renewables while making the case for clean energy investments, especially in the electricity sector. This review aims to provide important insights by analyzing the significant impacts of the COVID-19 pandemic on the global energy market. On the other hand, sustainable energy strategies are also discussed in detail. Finally, lessons learned amidst the costly battle against this invisible enemy could help policymakers and government leaders in identifying the appropriate renewable energy paths for their countries in a post-pandemic future.

<p>As climate change issues arise and become a global concern, to reduce carbon emissions has become an urgent issue to respond to. Therefore, the application of renewable energy plays more and more important roles in the energy domain nowadays, which may also bring significant impacts to the low-carbon electricity market transition. With the advantages of developing renewable energy, the Taiwan government anticipates achieving the goal of reaching 20% renewable energy in electricity structure by 2025. Moreover, Taiwan has carried out the most vigorous amendment on the Electricity Act in history to open the electricity market so that more stakeholders can participate in it to propel energy transition. Since the UK is the lead in this field, it is worth investigating. This paper takes the UK as a case study to analyze its evolution in recent decades after the deregulation of its electricity market from the retail side perspective. It expects to explore how the transition drove actors to empower their roles, or even create new roles and responsibilities, and engage in the low-carbon electricity market transition pathway. This paper expects the UK case as a great reference for Taiwan, which echoes the current scenario in Taiwan with the potential to deliver further insights.</p>

The national electricity market (NEM) of Australia is reforming via the rapid uptake of variable renewable energy (VRE) integration concurrent with the retirement of conventional synchronous generation. System strength has emerged as a prominent challenge and constraint to power system stability and ongoing grid connection of VRE such as solar and wind. In order to facilitate decarbonization pathways, Australia is the first country to evolve system strength and inertia frameworks and assessment methods to accommodate energy transition barriers, and other parts of the world are now beginning to follow the same approach. With the evolvement of the system strength framework as a new trending strategy to break the transition barriers raised by renewable energy project development and grid connection studies, this paper provides a high-level overview of system strength, covering such fundamental principles as its definition, attributes, and manifestations, as well as industry commentary, cutting-edge technologies and works currently underway for the delivery of a secure and reliable electricity system with the rapid integration of inverter-based resources (IBRs) in the NEM grid. The intent of this study is to provide a comprehensive reference on the engineering practices of the system strength challenge along with complementary technical, regulatory, and industry perspectives.

AbstractThe focus on expanding the sector coupling and binding the electricity system and end-user sectors like the transport and industry bring attention to environmental trade-offs. Otherwise, unintended environmental impacts could potentially impede the transformation process. Given that, this paper aims to identify and discuss environmental burdens that should require government attention. For that, the approach of coupling Life Cycle Assessment with the electricity market model (ELTRAMOD) is presented. Results show that the large impact on land use occupation as a regional issue requires attention due to diversified permitting mechanisms and eligibility criteria for solar fields among European member states. Metal and ozone depletion bring the challenge that transformation processes need attention on global limits related to finite resources and fugitive losses of anthropogenic substances.

Rooftop solar photovoltaics (PV) are accelerating the transition towards low carbon electricity systems in many countries, particularly in Australia. This review paper provides an overview of the (1) technical, (2) economic, (3) socio-political, and (4) regulatory and institutional aspects that should be considered concurrently when navigating the transition towards a rooftop PV-dominated electricity system. We consider the suitability of two prominent long-range transitions theories for understanding the importance and interaction of elements within these four aspects during the transition. The multi-level perspective (MLP) of transitions theory is considered best suited for this task as it addresses fundamental shifts in the socio-technical systems, rather than being weighted towards technological and/or economic solutions. We find that relatively little research has been undertaken where the renewable energy transition is being driven by the uptake of rooftop PV within the distribution network of established islanded electricity systems. These islanded electricity systems will be the first to experience system impacts from high levels of rooftop PV. This review provides further analysis of important gaps in understanding the rooftop-PV-led energy transition and the implications for policy makers in maintaining stable electricity supplies during the transition.

Energy Production System

The purpose of this paper is to describe a new way of producing renewable energy based on fjords as a water heater. We will call this system the Water-thermal Energy Production System (WEPS), because the basic idea is to extract heating and cooling energy from water. Although a prototype of WEPS has existed in Norway for more than ten years, a WEPS currently in operation has not been financially analyzed in the literature. Coastal parts of Norway have a potential of 5 TWh of profitable WEPS-facilities [9], due to convenient access to fjords containing water with stable all-season temperatures of about 4–12C when the depth of the water is about 50 meters. This stability of the water temperature makes it possible to extract energy from the fjord in a very efficient way. The potential for economically-profitable WEPS in other parts of the world has not been estimated. In order to answer such a question, more research is required. We have conducted a case study of a WEPS located in the Norwegian municipality of Eid. This is the first full-scale Norwegian WEPS, and it has been operating since 2006. The nascent years have passed, and the technology has been in operation for some years. In this paper, we have made an estimate of the business profitability and the external effects based on past empirical evidence and some assumptions about future development in some key figures. The results suggests that WEPS-Eid has been a profitable investment carrying a positive internal rate of revenue, even if the present underutilization in production capacity will continue in the future. Stability in energy prices for heating purposes has also gained customers compared to the more volatile prices of alternative renewable energy, like hydropower or wind turbines. The negative, external effects in the operating phase from WEPS-Eid are insignificant. Despite the significant profitability of the WEPS facility in Eid, there are two main obstacles for new entrants. There is a lack of relevant operational information for potential investors due to few facilities. This leads to uncertainty, and investments in WEPS appear as a risky business. Secondly, construction of a WEPS requires both big financial investments in digging and facilitating long trenches for a pipeline system and time and effort spent on acquiring the licenses needed for doing this work. A coordinating unit is probably required in order to get the necessary public and private licenses and to reduce fixed costs by coordinating other tasks in the same trenches, like pipes for water and sewer, fiber cables and tele-cables. In Eid, the local municipal administration was the coordinating unit.

The paper focuses on the quantitative analysis of Israeli Government’s targets of 10% renewable energy penetration by 2020 and determining the desired methodology (models) for assessing the effects on the electricity market, addressing the fact that Israel is an electricity island. The main objective is to determine the influence of achieving the Government’s goals for renewable energy penetration on the need for backup in the Israeli electricity system. This work presents the current situation of the Israeli electricity market and the study to be taken in order to assess the undesirable effects resulting from the intermittency of electricity generated by wind and solar power stations as well as presents some solutions to mitigating these phenomena. Future work will focus on a quantitative analysis of model runs and determine the amounts of backup required relative to the amount of installed capacity from renewable resources.

The UK’s exit from the European Union (EU) has potential ramifications for the country’s electricity sector, given its increasing interlinkage with other EU electricity systems. Brexit could hamper the development toward higher market integration and the realization of new interconnector projects. Moreover, a fall in the value of the Pound, resulting from Brexit in the medium term, could also affect the electricity trading structure. Combining a European electricity market model and a multi-criteria decision analysis tool, this study assesses the implications of Brexit for the electricity market of Great Britain (hereafter GB) for 2030, from the perspective of (i) political decision makers, (ii) electricity consumers, and (iii) producers. Results indicate that the implications of Brexit depend on the future development of the GB electricity system and on the objectives of the respective stakeholders. Possible opportunities brought by Brexit under a low-carbon trajectory contrast with greater challenges and tradeoffs between stakeholders under alternative power system development paths. Despite increased British autonomy in energy and climate matters, there remains interdependency between British and EU energy policy.
