Russia and Tajikistan are discussing the construction of large-scale solar power plants with a total capacity of up to 500 megawatts. The initiative builds on a memorandum signed in 2025, with both sides now working on implementation details and potential locations for the facilities.

Northern regions prioritised

According to Tajikistan’s Minister of Energy and Water Resources, Daler Juma, the country’s solar energy potential is largely concentrated in the south. However, electricity demand is significantly higher in the north, creating supply imbalances, particularly during winter.

As a result, the new solar facilities are expected to be developed in northern Tajikistan, where they could help reduce seasonal shortages and stabilise electricity supply. Authorities say the project is intended to strengthen the resilience of the national power system and improve energy availability for industrial and residential users.

Up to 500 MW of new capacity

The planned solar plants are expected to reach a combined capacity of up to 500 megawatts. Tajikistan has previously announced plans to develop two photovoltaic stations with a capacity of 250 MW each. Together, these facilities would significantly increase the share of renewable energy and help diversify the country’s energy mix.

Investment in the project is estimated at around $250 million, with commissioning expected by the end of 2026.

Reducing dependence on hydropower

Tajikistan’s energy sector currently relies heavily on hydropower, making electricity production vulnerable to seasonal water availability. During winter months, reduced river flows often lead to shortages and increased pressure on the grid.

The development of solar power is expected to complement hydropower by providing additional generation during daylight hours. Officials say this will improve system stability, reduce risks associated with water shortages, and support long-term energy diversification.

Regional cooperation in green energy

The Russia-Tajikistan initiative is also seen as part of broader regional cooperation in renewable energy. The project could support Tajikistan’s transition to cleaner energy sources while strengthening bilateral ties in infrastructure development.

Authorities note that expanding solar generation will contribute to improved energy security, reduced seasonal imbalances, and sustained economic growth. The planned facilities are expected to play a key role in modernising Tajikistan’s power sector and advancing its shift towards sustainable energy.
