At present, the state supports power generation and recoups the cost over 15 years through consumer bills. Contracts are awarded to wind projects with the lowest construction costs.
The current scheme is seen as "a reliable and understandable tool for investors and financial organisations," said Alisher Kalanov, head of renewables investment at state-owned venture capital firm Rusnano.
Kalanov's reservations over the proposed new scheme are shared by the Russian association for the development of renewable energy.
A change in the basic principle of guaranteeing investments will seriously increase the cost and risk of developing wind projections in Russia, the association said.
The government revealed last October its intention to introduce a new support scheme for wind power for the 2025-35 period.
Deputy prime minister Dmitry Kozak had suggested that further support should be tied to the volume of exports of Russian-made wind power equipment, as well as Russia-based operations for foreign suppliers.
