Azerbaijan's green energy sector is quickly increasing, with a focus on transitioning to alternative and renewable energy sources, lowering carbon dioxide emissions, and other progressive concepts. The country will host the renowned COP-29, declaring 2024 the “Year of Solidarity for the Green World”. Hydro power plants, in particular, are being built on a systematic basis in accordance with the President's directions to transform the the liberated regions into green energy zones. One of these regions is the Lachin district, where “Azerenerji” JSC is carrying out several projects. According to the green energy policy, hydro power plants have been erected at nine locations in the Lachin district. Thus, up to today in the Lachin district, the 8.25 MW Mishni, 8 MW “Gulabird”, and 6 MW “Alkhasli” HPPs have been reconstructed and put into operation, and the 4 MW “Sus” HPP has been restored. More than 77 mln kilowatt-hours of ecologically clean Green Energy have been produced at the hydroelectric power plants (HPP) put into operation by Azerenerji OJSC in Lachin district. The production of 77 million kWh of green energy saved 18 million cubic meters of gas and millions of tons of manat, avoiding the release of 32,000 tons of carbon dioxide into the atmosphere. Important precautions have been taken to protect the ecosystem, and eco-turbines of European origin have been installed at the power plants. Currently, five more hydro power plants with a total capacity of more than 40 MW are currently under construction in the Lachin district. More precisely, the works on “Agbulag” HPP with a capacity of 14.25 MW have already been completed. Construction works on “Aghbulag-2” HPP with a capacity of 14.7 MW, “Garagishlak” HPP with a capacity of 4 MW, “Mirik” HPP with a capacity of 3.5 MW, and “Zabukh” HPP with a capacity of 2.8 MW have been completed and installation and adjustment works are currently underway. These 5 hydro power plants are scheduled to be commissioned as part of the year of solidarity for a “2024-Green World".
