Most of the equipment was decommissioned in 2010. The expansion plans called for the construction of two new combined-cycle power units with a capacity of 230 MW each.
The power plant was upgraded by Natsproektstroy Companies. Teploelectroproekt Institute developed the design. In 2012, Mosenergo TEK specialists began construction and installation. New power units were built without stopping operations at the site of the existing SDPP. This made it possible not to interrupt the power supply to consumers. A specific feature of the plant is that due to the constrained conditions, the deep water intake pipelines run along the bottom of the Nizhnyaya Tura Reservoir.
The new natural gas-fired power units were put into operation on December 15, 2015. Each of them includes a gas turbine with a generator, a steam turbine, a heat-recovery steam generator, a turbo generator and auxiliary equipment.
