Title Performance of molten salt solar power towers in Chile Type

Volume 5 Issue 5 Pages 15 pp

Abstract Chile is facing important challenges to develop its energy sector. Estimations demonstrate that in its electricity consumption Chile will grow at an annual rate of 4.6% until 2030, despite ongoing efficiency improvements. To satisfy this demand in a sustainable way, the national energy policy promotes the integration of novel and clean power generation into the national power mix, with special emphasis on concentrated solar power (CSP). The present paper assesses the development of solar-based electricity generation in Chile by CSP, achieved by a Solar Power Tower plant (SPT) using molten salt as heat carrier and store. Such SPTs can be installed at different locations in Chile, and connected to the main national grid. Results show that each SPT plant can generate around 76 GWh(el) of net electricity, when considering solar irradiation as the sole energy source and at a 16% overall efficiency of the SPT process. For operation in a continuous mode, a hybrid configuration with integrated gas backup system increases the generating potential of each SPT to 135 GWh(el). A preliminary Levelized Energy Cost (LEC) calculation provides LEC values between 0.15 and 0.18 $/kWh, as function of the overall process efficiency and estimated investment cost. Chile's solar irradiation favors the implementation of SPT plants. (C) 2013 AIP Publishing LLC.

Title Assessing the economic viability of energy storage systems in the Chilean electricity system: An empirical analysis from arbitrage revenue perspectives Type
Year 2019 Publication Journal of Renewable and Sustainable Energy Abbreviated Journal J. Renew. Sustain. Energy
Volume 11 Issue 1 Pages 015901
Keywords
Abstract The emergence of high penetration rates of renewable energies in power systems presents a serious challenge in energy generation and load balance maintenance to ensure power network stability and reliability. Energy Storage Systems (ESSs) could play a relevant role in facing these challenges, as the technologies have passed the demo and prototype phases to a wide market implementation phase. The only remaining barrier for their implementation is their cost, but even this barrier is quickly disappearing. In this paper, we address the financial feasibility of storage technologies in electricity systems. In particular, we evaluate whether such technologies are economically sustainable and how far they are from becoming viable. For this purpose, we consider the Chilean electricity system and evaluate the maximum possible arbitrage revenues that could be achieved under ESS through benefiting from energy time shift, diminishing of transmission losses, and transmission upgrade deferral. The results show that the arbitrage revenues are still below the cost of storage systems. Further improvement in storage efficiency or a decrease in the cost of storage systems is still needed to make this type of investment financially viable in the near future.
