The U.S. nuclear industry has overcome a challenging period during which low wholesale market prices threatened the survival of nuclear power plants (NPPs). From 2017 to 2019, several U.S. states initiated out-of-market support schemes to bolster the financial conditions of NPPs. This paper...

Combined cycle (CC) plants are expected to play an important role in balancing generation of heat and electricity from non-dispatchable renewable energy sources. In this work, we study different retrofit options for using hydrogen in CC plants to reduce the plant's CO2 emissions. These options...

The worldwide matter of climate change, which has negative impacts on the Earth and its inhabitants, is attributed to the elevation in emissions of greenhouse gases (GHGs) caused by the burning of fossil fuels. Due to the disproportionate rise of GHGs in recent decades, global warming and...

The development of a country cannot be realized only through the amount of energy it produces and its industrialization. In a country where its people are left homeless and poor, and its cultural and natural riches are destroyed, the electricity produced is not a measure of development on its...

Purpose This research assesses the economic impact of biomass plant installations on Brazilian municipalities, focusing on (1) labor income, (2) sectoral labor income and (3) income inequality. Design/methodology/approach Municipal data from the Annual Social Information Report, the National...

This paper proposes a novel index, ECI (Electricity Climate-Compatibility Index), to measure global fossil fuel electricity generation alignment with climate targets. Net anthropogenic carbon dioxide emissions (CO2) must approach zero by mid-century to stabilise the mean temperature to well...

This study presents an archetype-based approach to designing effective strategies for low-carbon transitions in the power sector. To achieve global energy transition goals, a renewable energy transition is critical, and understanding diverse energy landscapes across different countries is...

Evaluating maintenance plans for power generation is a critical task managed by the National System Operator, as it is directly related to criteria such as operational cost, rationing, and availability of natural resources. This study identifies the most suitable maintenance schedule between...

The use of distributed energy resources (DER) programs, which include separate renewable energy (RE) programs, has expanded in residential as well as commercial structures as an outcome of recent technological developments. The virtual power plant (VPP) may improve the security and reliability...

The population increase and the demand for water and energy, accompanied by the implications of environment pollution for natural and human resources, indicate the critical necessity for a coherent movement towards nexus between water, energy, and environment. Due to the fact that power...

Iran holds the world's second-largest proven oil reserves and fourth-largest gas reserves. However, the heavy reliance on highly subsidized fossil fuel resources, coupled with growing demand, has led to their depletion and increased greenhouse gas (GHG) emissions. This research introduces a...

Finding fuel sources to replace coal in power plants is crucial in the march toward decarbonization. Biomass and ammonia are two options offering significant potential. Both can be used with coal or alone in newly constructed facilities or in modified power plants. Relatively new power plants...

Physical Assets play a critical role in infrastructures. Physical Asset governance is the required framework to implement asset management systems, including regulations and procedures that ensure its efficiency and effectiveness. Due to the dominant contribution of thermal power plants in...

In order to innovate the operation strategy of pumped-storage power stations and explore the establishment of a long-term mechanism for hydropower revenue sharing, this paper uses real option theory to design a new SBOO investment strategy for government-enterprise cooperation, and evaluates the...

Wave energy research is a reality in many parts of the world. It is essential for any wave power plant at the commercializing stage to accurately model and forecast its production to ensure efficient trading in the daily wholesale electricity market. Altogether, a reliable forecast is a required...

The increasing share of intermittent renewable energy sources supports the decarbonization of energy systems worldwide. Simultaneously, the fluctuating infeed from wind and solar photovoltaics leads to challenges, such as increased flexibility requirements. Bioenergy, a CO2-neutral and...

How does private equity ownership affect firms' environmental performance? Using electricity generating unit level data from U.S. fossil fuel power plants, we find that private equity-backed buyouts reduce output-scaled CO2 and NOx emissions by 5.5% and 8.1%, respectively. The declines are...

The flexibilization of electricity demand and production becomes increasingly important in energy systems with rising shares of fluctuating renewable electricity production. Power-to-heat and cogeneration units, combined with thermal storages, are considered as promising technologies for the...

In this paper, we study the impact of the 2013 reform of the Spanish support scheme for renewable on the revenues of photovoltaic plants. We break down the revenue change into two sources. The first lies in the difference between the payment per unit of electricity that the plant received under...

We quantify the net external effects of conventional and renewable electricity generators by analyzing housing prices in their vicinity. Using a Differences-in-Differences approach, we find that (1) wind turbines reduce prices significantly, (2) solar fields have no significant impact, and (3)...

We collect ownership data of U.S. power plants accounting for 99% of U.S. electricity generation over the 2008-2020 period. Domestic listed corporations have reduced their ownership from 69% to 54% of total generation, while private equity, institutional investors, and foreign corporations have...

We present a methodology to estimate fixed cost parameters relevant to the decision to operate, mothballor retire an open-cycle gas turbine (OCGT) using a dynamic discrete choice model, based on fuel andelectricity prices, as well as technical data and the operational status of OCGTs in the PJM...

Non-fossil energy increases the non-dispatchability of power system, requiring fossil-based technologies to provide back-up capacity as dispatchable source. In a coal-based economy like China, it is coal-fired units that act as back-up capacity. We show that increase of non-fossil energy...

Under the background of the continuous promotion of Henan Lankao energy Internet, there are problems that new energy can not be effectively utilized and the utilization efficiency is not high. However, the virtual power plant can solve this problem by optimizing the output of distributed...
