“…Studies on the cost-benefit of CSP mainly focus on the LCOE. According to , from 2014 to 2050, the LCOE of CSP decreased from RMB1.01/kWh to RMB0.60/kWh for the Blue Map scenario and was between RMB0.98/kWh and RMB0.50/kWh for the Roadmap scenario [15]; Hernández-Moro and Martínez-Duart (2012) used the life-cycle cost method to discuss the LCOE of CSP in the period of 2010-2050 [19]. Zhu et al (2015) found that the LCOE values of CSP in China varied between RMB1.2/kWh and RMB2.7/kWh [25], while Zhao et al (2017) pointed out that the LCOE of SCP in China was approximately RMB1.44/kWh [26].…”

In 2016, the first batch of concentrated solar power (CSP) demonstration projects of China was formally approved. Due to the important impact of the cost-benefit on the investment decisions and policy-making, this paper adopted the static payback period (SP), net present value (NPV), net present value rate (NPVR), and internal rate of return (IRR) to analyze and discuss the costbenefit of CSP demonstration plants. The results showed the following.(1) The SP of CSP systems is relatively longer, due to high initial investment; but the cost-benefit of CSP demonstration plants as a whole is better, because of good expected incomes. (2) Vast majority of CSP projects could gain excess returns, on the basis of meeting the profitability required by the benchmark yield of 10%. (3) The cost-benefit of solar tower CSP technology (IRR of 12.33%) is better than that of parabolic trough CSP technology (IRR of 11.72%) and linear Fresnel CSP technology (IRR of 11.43%). (4) The annual electricity production and initial costs have significant impacts on the cost-benefit of CSP systems; the effects of operation and maintenance costs and loan interest rate on the cost-benefit of CSP systems are relatively smaller but cannot be ignored.

Abstract-The high average solar radiation in Indonesia makes solar power plant an option to improve renewable energy-based electricity generation in the country. Currently in Indonesia, the photovoltaic (PV) plant has been more widely implemented, and several extensive researches on solar thermal plant have been carried out. In this paper, a comparative study on the 20-MW on-grid solar thermal and photovoltaic (PV) power plant is committed to measure the cost competitiveness of the technologies in Rongkop district, Indonesia; which is recently considered as the center for solar power plant in Indonesia. The simulation follows two installed energy capacity scenarios by the International Energy Agency and is committed up to year 2030, in accordance with the target year of United Nations' Sustainable Development Goals.By using System Advisor Model it is shown that a 20-MW solar thermal power plant equipped with 6-hour storage is able to produce slightly higher annual energy output than the solar PV plant design of similar capacity. However, the levelized cost of electricity (LCOE) values of both solar thermal plants with no storage and 6-hour storage significantly exceed the LCOE of PV plant throughout the years of simulation. This implies that in Rongkop, Indonesia the PV plant is a more economically competitive solar power plant technology to be implemented until 2030, compared to the solar thermal plant.

“…The levelised cost of energy (LCOE) of hybrid VRE-CSP plants have been evaluated in a number of studies. Parrado et al (2016) forecast the LCOE of a hybrid PV-CSP plant located in the Atacama desert. Looking at two alternative scenarios of global penetration of solar power, they forecast the LCOE from the present to 2050.…”

A challenge of solar energy production is the intermittency of solar availability. Photovoltaic (PV) arrays can be supplemented with battery storage to maintain steady output even during solar transient events. Concentrating solar power plants (CSP) solve this problem with thermal energy storage (TES), allowing production to be inexpensively shifted away from periods of solar availability. Hybrid PV-CSP plants combine the benefits of both methods, with the PV plant being used to produce electricity when the solar resource is available, and the CSP plant with large TES being used to provide the remaining power to track loads. However, during cloud transients, the power output of PV arrays dramatically changes, much faster than the dynamics of a CSP plant. This paper looks at the use of short term (up to 10 minutes) predictions of solar availability to anticipate these events and enable the plant to better track its required load.In order to do this, models of both the CSP and PV components of the hybrid plant are developed with suitable time dynamics. A model predictive control method is used to control the power output of the CSP plant and simulate the performance of the combined plant for 1-1.5 hour periods of variable solar availability. Three different methods of solar availability prediction are used: no predictions, perfect knowledge, and predictions of direct normal irradiance (DNI) from Pidgeon (2014).For the periods simulated, the use of perfect predictions reduced the RMSE of plant power output with respect to a reference power output by 35-50%. By comparison, the causal predictions from Pidgeon (2014) only gave a 5-10% improvement. Both of these methods also reduced the size of battery storage required to supply extra power to meet the required load, which can contribute to lowering the costs of such a hybrid plant. This shows that better predictions of solar availability forecasts can improve the load tracking ability of a PV-CSP plant. This work also gives some insight into improvements that can be made to solar availability predictions to improve the performance for this kind of application.
