Iran (IMNA) - The government’s latest initiative envisions constructing solar power plants adjacent to hydroelectric dams, leveraging Iran’s natural resources and existing infrastructure. This project, characterized by innovative ideas and practical solutions, aims to enhance grid stability, reduce carbon emissions, and help the country achieve its ambitious energy goals.
At the core of Iran’s strategy is the concept of synergy. Recently, a Memorandum of Understanding (MoU) was signed with the Iranian Renewable Energy and Electricity Efficiency Organization (SATBA) to establish solar power plants at strategic dam sites nationwide. Officials highlight that combining solar with hydroelectric power will effectively integrate renewable sources into the energy mix while decreasing reliance on fossil fuels.
The potential of renewables in addressing Iran’s energy challenges is immense, given the country’s abundant solar, wind, biomass, and geothermal resources. The goal is to generate 500 megawatts of new solar capacity, a crucial step towards achieving broader renewable energy targets. With numerous sunny days, solar power is uniquely positioned to provide a reliable and sustainable energy source.
A particularly innovative aspect of this energy transition is the development of floating solar power plants. As urban land prices rise, alternative locations for solar farms are increasingly necessary. Iran is turning to its extensive network of dams and reservoirs as potential sites for floating photovoltaic (PV) systems. A pilot floating solar project has already been launched at Mahabad Petrochemical Company, utilizing domestically developed floating structures, paving the way for larger-scale initiatives and showcasing the country’s growing expertise in renewable energy.
Floating solar power offers significant environmental benefits, especially for a country like Iran, which faces water scarcity and harsh climatic conditions. By placing solar panels on water bodies, Iran can reduce water evaporation from reservoirs, conserving vital resources while enhancing solar panel efficiency by 5 to 10 percent due to the cooling effect of water.
Economically, floating solar presents a cost-effective solution to Iran’s increasing energy demands. Its ability to boost efficiency, minimize water evaporation, and provide a sustainable energy source could ultimately lower electricity production costs, contributing to long-term energy stability.
The synergy between solar and hydroelectric energy is particularly compelling. Iran has a rich history of hydropower generation, with the Iranian Water and Power Development Company managing over 70% of the country’s hydroelectric plants. While these plants have traditionally offered a reliable energy source, the development of new hydroelectric projects has slowed due to financial constraints and drought challenges.
By integrating solar energy with hydroelectric power, Iran can mitigate the intermittency issues that often affect renewable sources. Solar energy is generated during the day, while hydroelectric power can provide a steady electricity flow at night. This complementary relationship can stabilize the grid, ensure a consistent power supply, and enhance the resilience of the energy system. During dry seasons, solar energy can offset reduced hydroelectric output, while hydroelectric plants can compensate for limited solar generation during rainy seasons, creating a more reliable energy mix.
Despite the promising outlook, Iran’s renewable energy ambitions face challenges. The technical complexities of floating solar systems in fluctuating water levels present engineering hurdles, and the financial costs of these projects are higher than those of land-based solar farms due to specialized materials and installation processes. Additionally, securing the necessary capital for large-scale renewable energy projects remains a significant challenge, exacerbated by years of international sanctions and domestic financial pressures.
However, the global success of floating solar systems in countries like China, India, and South Korea demonstrates the viability of this technology. With rising land costs and increasing pressure to conserve water resources, floating solar is becoming a crucial part of the renewable energy solution worldwide. Iran’s initiative to integrate floating solar into its renewable energy strategy positions it at the forefront of this emerging trend, allowing the country to capitalize on its vast water resources and abundant sunlight for significant advancements in energy production and water conservation.
