Coalstar coal mining holding will supply coal to RusHydro's Far Eastern thermal power plants at prices included in electricity and heat tariffs. Supply volume will amount to just over 1 million tons of coal per year, or 10% of the total consumption by RusHydro's thermal generation in the Far East. This will reduce RusHydro's losses from the purchase of coal at prices higher than the regulator took into account in the tariffs.
