Regulation and Energy Policy, Hydropower Plant Upgrading, and Environment

Improvements in existing hydroelectric power plants can increase quantity of production, but very often they are also designed to improve its quality, that is, peak generation capacity and availability of reserve energy, which in turn leads to a reduction of emissions in the producer part. An adequate valuation and economic recognition of the energy quality in remuneration seems essential to encourage these improvements. Frequent size discrimination acts against this recognition, because quality of energy is more often present in conventional-sized installations.

Abstract Every year, there are many floods on the planet, which have a significant impact on ensuring the safety of people and affects the quality of life. The development of modern modelling technologies makes it possible to predict various scenarios for the development of the situation and reduce the likelihood of negative consequences. This issue is especially relevant for settlements located in the immediate vicinity of hydroelectric power plants, since by regulating discharge costs from hydroelectric power plants, it is possible to safely pass flood waters avoiding flooding of residential buildings and infrastructure, but this requires knowing the flooding zones at different water levels and discharge costs. This paper presents the results of solving the problem of modelling the dynamics of flood waters within the boundaries of the settlement of Krasnoyarsk. To calculate the flooded areas, the TUFLOW program was used in the Surface-water Modelling System modelling environment, as well as neural network forecasting using the NeuroPro software product. The simulation results made it possible to predict local flooding of the settlement during the flood of 2021 and take preventive measures to reduce the risk of flooding.

Koto Panjang Reservoir is one of the hydroelectric power plants in Indonesia, located in Kampar Regency, Riau Province. This paper aims to determine the water quality and tropic status of the Koto Panjang Reservoir. The research was carried out along the Koto Panjang Reservoir, covering the floating net cages area, inlet, outlet, and the center of the reservoir. Water samples were collected twice a year, February and September 2017. The results showed that the water quality of Koto Panjang reservoir is still within the tolerance range for the aquatic organisms' life, including fish. Based on the TSI analysis, the Koto Panjang Reservoir throphic status was categorized as eutrophic to heavy eutrophic. This study recommends that relocating floating net cages is necessary so that the nutrient load will not only be concentrated in one location. The efficiency of using the feed for floating net cages could minimize the waste.

The activity of any enterprise is always associated with risk. This is especially true of hydropower enterprises, since they work in the conditions of renewable energy sources, which are directly dependent on nature. This necessitates the introduction of the concept of risk management, which will take into account risk factors in the process of developing and approving management decisions.Hydroelectric power plants play an important role in ensuring the required quality of electrical supply, participating in regulating voltage and frequency, covering the uneven part of daily load schedules, guaranteeing measured operation modes of nuclear and thermal power plants, increasing the safety and economy of operation of the final cycles load, performing the function of a temporary emergency and operational power reserve.The purpose of this article is to analyze the characteristics of risk management in hydropower, as well as to justify the development and feasibility of introducing the concept of risk management in hydropower.

The main theoretical aspects of the environmental risks as a scientific category, the definition of environmental risk in the Ukrainian legislation, as well as major environmental risks associated with the construction and operation of hydroelectric power have been described. Taking into account the largescale plans of the hydroelectric power plants building in Ukraine after the implementation of "green" tariff the determination and issue the appropriate environmental risks assessment is crucial for making the reasonable management decisions on the construction of hydroelectric power or abandon it. Key words: environmental risk, hydropower plant.
